When does bamboo mature?

Question 1: When does bamboo mature into different kinds of bamboo? Heterobamboos are perennial lignified plants with aboveground stems (bamboo poles) and underground stems (bamboo whips). Bamboo poles are usually cylindrical, rarely quadrangular, and the internodes are connected, often hollow, rarely solid, and the internodes are composed of reeds and rod rings. Branches on each node. There are two kinds of leaves, one is stem and leaf, commonly known as leaves; The other is the vegetative leaf, which is needle-shaped and its size varies with varieties. Bamboo flower is composed of pulp, stamen and pistil. The fruit is mostly caryopsis. Most of bamboo's life is a vegetative growth stage. Once it blooms and bears fruit, all plants will die and complete a life cycle. Because bamboo is a perennial flowering plant, bamboo flowering is a normal natural phenomenon and belongs to a process of bamboo fruiting and reproduction. People in ancient China have observed this phenomenon for a long time. There is a saying in Shan Hai Jing more than 2,000 years ago: "Bamboo bears flowers, and its years will surely wither." Record. In the Bamboo Spectrum written by Dai Kai in Jin Dynasty, it is recorded: "The medicine must be sixty, and it will take six years." Its annotation is: "Bamboo roots change easily in sixty years, and roots change easily and die easily." However, bamboo mainly reproduces asexually. Every spring, bamboo shoots grow from underground bamboo whips and then develop into new bamboo. The bamboo whip is not its root, but an underground stem. Underground stems can be divided into three types: uniaxial underground stems can continue to grow, with buds on both sides and lateral buds developing into bamboo shoots; Axial terminal buds develop into bamboo shoots, and lateral buds produce new underground stems, which are connected to form axial buds. Underground stems produce dense bamboo stem clusters, which belong to this category. There is also a compound shaft type, which is a mixture of the above two. The sexual reproduction of bamboo, like other flowering plants, first blooms and then bears seeds to complete the whole growth cycle. There are three types of bamboo flowering cycle due to different bamboo species: few bamboos can bloom every year, and after flowering, bamboo stalks will not die, but they can still whip up bamboo shoots; Most bamboos bloom only once in the whole growth process, and there is a certain period, ranging from 40 to 80 years. After flowering, the stems and leaves turn yellow and die, and the underground stems gradually turn black and lose their germination ability. The seeds formed are called bamboo rice, which can grow into new bamboo, arrow bamboo and bamboo after planting. The other is sporadic flowering from time to time. Bamboo forests do not die after flowering, such as Zizhu. Bamboo, Fargesia macrophylla, etc. All belong to the category of regular flowering. This kind of bamboo has a long flowering interval, usually 50-60 years; Some even open once every 100 years. However, no matter which year the bamboo pole grows, as long as the age of the bamboo whip is the same or similar, then the flowering time is roughly the same. Even if the ecological environment is very different, flowers can bloom at the same time on sunny slopes, shady slopes, steep slopes and gentle slopes, with different soils and different altitudes. 3. Bamboo will also blossom. Because different bamboo species have different flowering cycles, this is also influenced by heredity. Some bamboos take more than ten years or decades to blossom, such as Dendrocalamus latiflorus and Dendrocalamus latiflorus, which take about 30 years to blossom, Dendrocalamus affinis and Dendrocalamus latiflorus, which take 32 years to blossom, and some kinds of bamboos take more than 80 years to blossom. Some even take a hundred years to blossom, such as Zhu Gui, which takes 120 years to blossom. Of course, there are a few exceptions, such as Phyllostachys pubescens, which bloom once a year or so; On the other hand, Tang Zhu and Xiaoshunzhu bloom irregularly. It is precisely because bamboo is rare to bloom, after flowering, the green leaves wither, branches wither and die in batches, so some superstitious people mistakenly think that bamboo flowering is an "ominous sign", which makes people feel mysterious and has various questions about this natural phenomenon. What kind of bamboo dies in pieces after flowering? Although scholars at home and abroad have different opinions on the causes of bamboo flowering, they can be summarized as "recycling theory" and "nutrition theory". The former mainly thinks that bamboo is a perennial gramineous plant. Like other Gramineae plants, it has a certain growth cycle and can blossom and bear fruit after a certain period of time. But this statement ignores and denies the influence of environmental conditions on flowering cycle. The latter believes that inadequate nutrition, poor management, dry weather and poor growth environment are the reasons for bamboo flowering. But it ignores the inherent developmental essence of plants and overemphasizes the influence of environmental conditions. This is true of plants that once bloomed, such as wheat and rice, and bamboo is no exception. When bamboo blooms, the nutrients stored in bamboo whips and bamboo poles are exhausted, and most species, such as Phyllostachys pubescens and pear bamboo, are used up. After flowering, all the above-ground and underground parts died. However, a few bamboo species, such as Phyllostachys pubescens, Phyllostachys cinnamomi, Phyllostachys pubescens, etc., die after flowering, but the buds in the underground part can still rejuvenate and renew; There are also some bamboo species, such as Phyllostachys pubescens, Phyllostachys pubescens, etc., whose leaves remain green after flowering and the underground parts do not wither. & gt

Question 2: When will bamboo mature? July

Question 3: What is the maturity time of bamboo in my world? Direct bone meal

Bone meal is made of bones falling from the bones that have been killed and used as dyes or fertilizers.

Like all dyes, bone meal can be used directly on sheep to dye white. Because bone powder can't turn dyed wool squares back to white on the workbench, this is its only direct use, but it can still be mixed with other dyes to produce new colors.

Fertilizer is the unique use of bone meal.

When it is used on crops or saplings, it will consume one unit of bone meal and make plants grow immediately, but it has a certain failure probability and needs to be reused. After use, the crops will mature immediately, and the saplings will grow into trees, as long as there is enough space.

In addition, the bone meal used on the saplings without enough space to grow into big trees will be consumed, and there is no visible effect.

When planting trees, players must be careful not to be in places that hinder the growth of new leaves or wood, lest they grow in the box where the player's head is located, causing suffocation.

Question 4: When will the bamboo rice mature? Put it in the pot for about 20 minutes.

Question 5: When will bamboo blossom and bear fruit? It is the characteristic of seed plants, and bamboo is no exception. It's just that many bamboo species have been growing for decades before entering the stage of sexual maturity. Finally, they bloom, bear fruit and die, the seeds fall into the soil, and then they grow and grow into clumps.

Probably because most species of bamboo don't blossom and bear fruit every year like ordinary angiosperms, some people mistakenly think that bamboo doesn't blossom and attribute it to natural disasters such as climate anomalies or earthquakes, and some even think it is an ominous sign.

Our people have long observed the phenomenon of bamboo flowering. More than 2000 years ago, Shan Hai Jing recorded that bamboo blooms, but it will wither in a year. According to the Bamboo Spectrum written by Dai Kai in Jin Dynasty, it takes six years to recover. Its annotation is: bamboo roots change easily in sixty years, and roots change easily and die easily.

According to scholars' research, there are three flowering habits of bamboo: one is to bloom once a year or once a year, such as bamboo with line marks and bamboo with clustered buds. The second category is bamboos with irregular flowering periods, such as Tang Zhu and Xiaoshun bamboos. The third kind is a piece of bamboo that blooms periodically, and the flowering time is about 30 years, such as Dragon Bamboo and Banna Sweet Bamboo. There are about 32 years of flowering, such as bamboo and vest bamboo; Some flowers only bloom for more than 80 years, such as some kinds of bamboo; Some even have a flowering interval as long as 120 years, such as Zhu Gui. No matter which year the bamboo stems are older, as long as the bamboo whips are the same or similar in age, the flowering time is roughly the same. Even if the ecological environment is very different, such as shady and sunny slopes, steep and gentle slopes, different soils and different altitudes, they all bloom at the same time. Some bamboo varieties will bloom at the same time even if they are transplanted thousands of miles away. It can be seen that the internal factors play a leading role in the flowering and fruiting of bamboo, and the external ecological environment can only promote or delay it to a certain extent, but can not change the characteristics of bamboo flowering in pieces regularly.

When bamboo blooms, the nutrients preserved by bamboo whip and bamboo stalk are absorbed and consumed by flowers, which has a great influence on bamboo. Most of the aboveground and underground parts die after flowering, and bamboo forests can only be restored by natural seed regeneration or artificial seed seedling regeneration. A few species die on the ground after flowering, but the underground buds can still rejuvenate and regenerate, so the bamboo forest can be restored by renewing the bamboo whip. Some kinds of plants still keep green leaves after flowering, and the underground parts do not die. When they bloom, cut off the branches as soon as possible to reduce nutrient consumption and maintain the normal growth of bamboo forests.

Large areas of bamboo forests will cause great disasters. For example, in the giant panda producing area of Sichuan, China, due to the large-scale flowering of orange bamboo and arrow bamboo in China, a large number of rare animals such as giant pandas died due to lack of food. Another example is the large-scale flowering of cinnamon, which accounts for 30.7% of the bamboo forest area in Japan, which once led to the closure of Japanese bamboo enterprises. But things are divided into two, which is beneficial to the flowering and fruiting of bamboo and the reproduction and rejuvenation of bamboo from the perspective of systematic development.

Bamboo flowering has long been recorded in ancient books in China. Shan Hai Jing wrote: "Bamboo changes its roots every sixty years, but the roots will bloom, the flowers will bear fruit, the fruit will die and the fruit will revive."

Bamboo blossoms and bears fruit, and the fruit is called bamboo rice. Bamboo rice looks similar to edible rice and can also be eaten. Bamboo rice is rich in nutrition, and its main components are starch, crude protein, crude fat and crude fiber. It can be ground to make cakes, and the price of bamboo rice is much more expensive than ordinary rice. Bamboo and rice can also germinate, grow seedlings, afforest and breed offspring.

Bamboo seldom blooms. In the famine of 1960, all the bamboos in the mountain actually blossomed and formed "rice", which helped many people survive the famine.

Even if you move back to a small bamboo seedling, it may bloom after only a few years. Because, not every bamboo has its own life, they were originally only the primary ones connected by blood. So their life, death and age are not calculated by their own age, but by the trees of their ancestors.

Bamboo blossoms, and there are even more ominous predictions, such as: regime change, owner's move, human death, natural disasters and so on.

South China may not produce sesame seeds. People often say that "the bamboo flowers bloom higher and higher", which seems to be a good thing.

Question 6: When will bamboo blossom? Because different bamboo species have different flowering cycles, this is also influenced by heredity. Some bamboos take more than ten years or decades to blossom, such as Dendrocalamus latiflorus and Dendrocalamus latiflorus, which take about 30 years to blossom, Dendrocalamus affinis and Dendrocalamus latiflorus, which take 32 years to blossom, and some kinds of bamboos take more than 80 years to blossom. Some even take a hundred years to blossom, such as Zhu Gui, which takes 120 years to blossom. Of course, there are a few exceptions, such as Phyllostachys pubescens, which bloom once a year or so; On the other hand, Tang Zhu and Xiaoshunzhu bloom irregularly.

It is precisely because bamboo is rare to bloom, after flowering, the green leaves wither, branches wither and die in batches, so some superstitious people mistakenly think that bamboo flowering is an "ominous sign", which makes people feel mysterious and has various questions about this natural phenomenon.

Why do bamboo die in pieces after flowering? This is a question that people have been puzzled for a long time, and scientists also hold different views on it. Some scientists believe that bamboo will inevitably get old when it reaches a certain age. In order to reproduce, it will blossom and bear fruit before the end of life. Their explanations are as follows: roots, stems and leaves of plants are called vegetative organs, and their growth is called vegetative growth; Flowers, fruits and seeds of plants are called reproductive organs, and their growth is called reproductive growth. The flowering habits of plants can be divided into two categories: one is once flowering plants, such as rice, wheat, bamboo and so on; The other is plants that bloom many times, such as apples and pears. Once-flowering plants only bloom once in their lives, which is characterized by vegetative growth in the early stage of growth. When vegetative growth reaches a certain stage, reproductive growth gradually turns to superiority, and finally blooms and bears fruit. Because flowering and fruiting consume a lot of organic nutrients, which come from roots, stems and leaves, after flowering and fruiting, most of the nutrients stored in the vegetative organs are consumed, and they can no longer live and die gradually. This is true of plants that once bloomed, such as wheat and rice, and bamboo is no exception. When bamboo blooms, the nutrients stored in bamboo whips and bamboo poles are exhausted, and most species, such as Phyllostachys pubescens and pear bamboo, are used up. After flowering, all the above-ground and underground parts died. However, a few bamboo species, such as Phyllostachys pubescens, Phyllostachys cinnamomi, Phyllostachys pubescens, etc., die after flowering, but the buds in the underground part can still rejuvenate and renew; There are also some bamboo species, such as water bamboo, flower bamboo and so on. After flowering, the leaves of plants remain green and the underground parts will not die. However, flowers should be picked as soon as possible to reduce nutrient consumption and ensure the normal growth of bamboo forests.

In fact, bamboo flowering has long been recorded in ancient books in China. Shan Hai Jing wrote: "Bamboo changes its roots every sixty years, but the roots will bloom, the flowers will bear fruit, the fruit will die and the fruit will revive." There is a similar record in the Book of Jin: "In the second year of Emperor Jinhui's Yuankang, grass and bamboo all bear seeds such as wheat, and in the spring of the next year, bamboo in Brazil blooms."

In modern times, there are also many records about bamboo flowering at home and abroad. Interestingly, sometimes bamboo blooms across mountains, provinces and continents. For example, in 1907, bamboos bloomed, while in the Royal Botanical Garden in Wan Li, bamboos bloomed at the same time. For example, the bamboo forests in Jiaxing, Zhejiang, China bloomed at 1933, and all the bamboo forests around Matou Town, Lu 'an, Anhui Province bloomed at the same time.

Bamboo flowering is a physiological phenomenon, which generally occurs in bamboo gardens with long-term drought, soil hardening, overgrown weeds and old whips. This is because bamboo is seriously short of water and nutrition, photosynthesis is weakened, nitrogen metabolism is reduced, and sugar concentration is correspondingly increased, resulting in a high sugar-nitrogen ratio, which creates conditions for the formation and flowering of flower buds. It can be seen that bamboo flowering is caused by poor growth environment. Therefore, according to the characteristics of bamboo species, corresponding management measures can be taken to control bamboo flowering. For example, measures such as loosening soil, fertilizing, covering soil, watering, digging bamboo piles, and controlling pests and diseases can be taken to create a suitable growth environment for bamboo, so as to avoid flowering.

Question 7: How to distinguish bamboo? The length of growth mainly depends on bamboo skin. Generally, those with green hair and white hair are tender, those with light green hair belong to mature bamboo, and those with yellow or brown spots are older.

In addition, it can also be judged from the hardness of bamboo and the density of branches and leaves.

Question 8: When is the best season to grow bamboo? Bamboo planting season is generally in autumn, winter and spring every year, that is, 10 to February of the following year, which is a good season for afforestation.

Question 9: When will mangosteen mature? May to September is the season when mangosteen is abundant, so we should choose small and medium-sized ones. The pedicel of fresh mangosteen is green, and the shell is soft and elastic when pinched. When opened, the meat inside is pure white. If you can hold the shell with your thumb and forefinger, it means it is mature. If the shell is as hard as a stone, it is probably inedible. If there is a lot of yellow juice in Goldie, she decides not to buy it. Look at mangosteen. There are many petals there, and there are many petal pulp in it. Mangosteen shells dry easily in the wind, so it is recommended to buy as much as you eat. Cold storage is the main way of preservation, which needs to be kept in the refrigerator. Usually, after five days of storage, the taste will get worse and worse. It can only be kept for ten days at most.

May and June are usually the peak season. Most mangosteen on the market are imported, native to Malay Peninsula and Malay Archipelago, and cultivated in Southeast Asia such as Malaysia, Thailand, Philippines and Myanmar.

Mangosteen shell is thick, hard and purple, with soft meat and sweet and slightly sour taste. Very delicious. If you don't like durian, eat mangosteen, which is also a good fruit. In hot Thailand, mangosteen is in the hottest summer, so eating mangosteen is of great help to reduce fire, clear heat, cool and delicious.

Mangosteen is a unique fruit with a thick shell, which is not easy to damage the pulp. The life span of fruit trees is over 70 years. The planting cost is not high. But it will take seven or eight years to harvest. Unlike rambutan, it only takes three or four years to have fruit. Liu Hua can also be sold in five years. Mangosteen produced in Rayong, Thailand is of good quality.
