How long does litchi blossom?

Question 1: When will litchi blossom? I was in Guangdong from March to April. Now the litchi has blossomed, so I can eat litchi in May.

Question 2: How long does it take for litchi to blossom and mature? Litchi generally germinates in February 65438-June 1, blooms in February-April, fruits develop in May-June, fruits are harvested in June-June, autumn shoots germinate in August-September, and mature in June10-June1autumn shoots. According to local experience, the key point of fertilization for litchi fruit trees should be the third fertilization.

Question 3: When does litchi blossom and bear fruit? Litchi blooms in March-April and ripens in May-August.

Question 4: When will the litchi tree blossom? 1. The root system of litchi varies with the propagation mode of seedlings. The taproots of seedling trees and grafted trees have developed; The lateral roots and fibrous roots (ring branches) of litchi propagated under high pressure are developed and there is no main root. The root system of litchi consists of many thick and developed lateral roots and slender and dense fine roots. The newborn young root is white and crisp, commonly known as "bean sprout root". The old roots are grayish brown. Litchi roots and fungi grow together to form mycorrhiza, which is a total branching type. Second, the trunk and branches (1) Litchi trunk is tall, the tree height is more than 16.0 meters, the crown diameter is more than 15.0 meters, and the trunk is thick. The bark is rough and slightly cracked, but smoother than longan, grayish white, taupe or dark brown. There are differences in color and roughness of tree epidermis among different varieties. Shuidong black leaf, jujube and other varieties have gray trunks and smooth skins, while black leaf, glutinous rice paste, stand out and other varieties have dark brown trunks and rough skins. Trunk height and crown size are related to soil, varieties, propagation methods and cultivation management. Poor soil layer or high groundwater level, small crown; The soil layer is deep and fertile, and the crown is large. The trunk of the plant propagated by barge branches is not obvious, mostly 3-4 trunks, which are multi-trunk, and the crown is semi-circular with an opening; Seedling with obvious trunk, single stem type and round crown. Litchi trunk wood texture is delicate and reddish brown. (2) The leaf buds and flower buds at the top of the branches are single buds, showing * * *, but the terminal buds are protected by young leaves. The top of the branch tip has strong advantages, and the terminal bud is easy to germinate into branches; Only 1-2 axillary buds with strong branches can germinate, and the rest are latent buds. After the new buds mature, some tips die and the first lateral buds become terminal buds. Litchi branches can be divided into 1 according to their properties. Vegetative branches are called vegetative branches when they are extracted from leaf buds. Generally, the length is 20-30 cm, and the long branch is 60- 100 cm. The last branch with sufficient nutrition grows well and can be heading and flowering in the second year, which is called the fruiting mother branch. 2. Branches that can blossom and bear fruit are called fruiting branches. The flower buds of litchi are mixed buds. When the young spike meets high temperature, the fruiting branches of leafy inflorescences are extracted; When the ear development process encounters low temperature, the leafless pure inflorescence is extracted, and the fruiting branches are not obvious, which becomes the main axis of the inflorescence. The characteristics of litchi bamboo shoots vary from variety to variety. The branches that stand out are dense and short; Large-scale, water east sparse long; Cinnamon tastes hard and crisp. Litchi shoots are yellow-green, and the epidermis is covered with many gray-white round or oval spots; Mature branches are grayish brown; Perennial branches are darker in color. Three, litchi leaves are even or odd pinnate compound leaves, leaflets are generally 2-5 pairs, opposite or alternate. Among them, the compound leaves of stand out and plum are composed of 1-8 leaflets, with 2-4 leaflets more. Litchi leaflets are elliptic or lanceolate or ovoid, 5- 16 cm long and 2-5 cm wide, with short stalks and acuminate or acute tips. Leaf base is round or wedge-shaped. The leaves are intact, tough and shiny, and some of them are wavy. The leaves are green and the back is blue and white. The new tender leaves are copper or yellow-green, and turn green when they mature. The main veins on the back of leaves are raised, and the lateral veins are not obvious, and the lateral veins on the surface of leaves are generally not obvious. The length, width, size and depth of leaves vary with varieties, which can be used as one of the characteristics of variety identification. Four. Litchi with flower (1) spike structure are clustered inflorescences arranged in a cone shape. Spike consists of main spike, lateral spike, branch spike and flower group. There are also some axillary spikes at the base of the main spike (main root) and at the axils of leaves. A small flower group is generally formed by zigzag arrangement of three flower buds, and two small flower groups and a single flower bud in the middle, that is, seven flower buds, form a flower group. Some big spike flower heads are also composed of two flower groups and a single bud in the middle, that is, 15 buds form a big flower group. Generally, 2-7 flower groups (or large flower groups) form a branch. 3- 10 branches to form a lateral spike. 6-20 lateral spikes and several axillary spikes form a convergent panicle. The density of small flowers on litchi inflorescence varies with varieties. Cloves and cinnamon inflorescences are scattered; Plums and stems have short flowers and many flowers, so they feel dense; March red, great creation, thallium litchi with thick inflorescence and many flowers. The number of flowers per inflorescence varies from variety to variety. More than 800 flowers per inflorescence, more than 0/600 flowers in March, more than 0/300 flowers in sugar and more than 0/00 flowers in cinnamon. (2) Inflorescence size varies from variety to variety, and has certain correlation with fruit maturity, fruit size and leaf size. First, early-maturing varieties such as March Red, Jujube, Black Leaf, etc. have large and long inflorescences and thick pedicels, which are called "long-legged flowers" by fruit farmers, characterized by many flowers and large fruit shapes; Late-maturing varieties, such as Guiwei, Heli, glutinous rice paste, etc. The inflorescence is short and the pedicel is thin, which is called "short-footed flower" by fruit farmers, which is characterized by few flowers and medium fruit shape. & gt

Question 5: When will litchi blossom? What season will bear fruit? It blooms in March-April and bears fruit in May-July.

In fact, there are many varieties of litchi, depending on what litchi it is. Her flowering and fruiting periods are different.

Chenzi

It is a must among litchi in Fujian. When it matures, it gives off a faint fragrance, which is refreshing. Putian and Xianyou are the most famous areas. Cai Xiang. Litchi spectrum. This variety has been introduced to the United States at the beginning of this century and cultivated in southern Australia.

Hang green

It is the treasure of litchi in Zengcheng, Guangdong Province, and one of the famous litchi varieties in Guangdong Province. Tribute of feudal times. "Lingnan litchi spectrum" describes: its fruit "protrudes a little higher beside the pedicle, which is called the dragon head; One side is low, called phoenix tail. Dressed in red when cooked, there is a green line running through it, so it was renamed. " The fruit is as big as a chicken print and the core is as small as a pea; Pericarp dark red with green; The lobes are flat and the suture lines are obvious; The meat is thick and crisp, sweet and juicy, fragrant and unique in flavor. Mature from late June to early July. At the 2002 Green Litchi Auction held in Zengcheng City, Guangdong Province, a litchi sold for 555,000 yuan. This litchi was picked from an old tree hanging green in Zengcheng "Xiyuan". This tree has a history of more than 400 years, and it bears little fruit every year. Its characteristic is that the shell color is slightly green and six dividends, and a green line runs through the fruiting body. The flesh is crisp, tender and slightly fragrant, and it is wrapped with non-wet paper after peeling. Become the most expensive fruit in history.

Question 6: How many days does it take for litchi to blossom from bud to month? I haven't counted them, but it's time for litchi to grow, and the princess smile won't bloom until February.

Question 7: When is the flowering period of red litchi in March? March red litchi blooms in1~ March under suitable conditions, the flowering period is about 40 ~ 50 days, and the fruit matures in the first half of May.

March red litchi, referred to as March red, is a variety of litchi. Because this variety matures in the late March of the lunar calendar, it is named March Red, which is the most precocious variety. The fruit of this variety is heart-shaped, wide at the top and sharp at the bottom; Lobes are different in size, irregularly arranged, and suture lines are not obvious; Thick skin, reddish; The meat is yellowish-white, slightly tough, rough in texture, large in core, sweet and sour in taste, and has residue after eating.

Question 8: How to nurse litchi during flowering and fruiting?

Litchi flower buds mature, followed by flowering and fruiting. The management of litchi in flowering and fruiting period focuses on assisting pollination, improving fruit setting rate, reducing fruit drop in growing period and promoting normal fruit growth and maturity. The growth process of litchi from flowering to fruiting is a complex physiological process. It usually takes two and a half months from pollination to fruit ripening (late March). During this period, due to the influence of external environmental factors, such as temperature, moisture, fertilization, pests and diseases, the physiological conditions inside the tree often change greatly, and unfavorable factors will lead to low fruit setting rate and fruit development stop or fall off. Therefore, during the flowering, pollination and fruit growth and development of litchi, it is necessary to strengthen management, seek advantages and avoid disadvantages in order to obtain a good harvest.

First, assist pollination at flowering stage to improve fruit setting rate.

1, water shaking and retting prevention in rainy days: litchi flowering, continuous.

In rainy or foggy days, small water droplets often accumulate on the ears, causing the buds and flowers to be flooded. The anthers of open flowers are difficult to crack and emit pollen, and the sugar and tannin released by open flowers are dissolved in the water of the ear, which is easy to cause browning or mildew of the ear, seriously affecting flowering and pollination, and leading to the unfruitful flowers. Therefore, when litchi blossoms in this kind of weather, we should pay attention to shake the tree in time on short sunny days or when there is no rain, and remove the accumulated water on the flower spike (it is best to spray water first and then shake it in foggy days). You can use a long wooden stick with branches, wrap the branches with soft glue, and then shake them vigorously against the tree to shake off the stagnant water on the flower spike and the flowers that have blossomed and withered, so as to ensure that the flower spike is dry and ventilated and improve the environment conducive to pollination.

2. Spray water on dry days to prevent burning flowers: When litchi blossoms, especially when it is sunny and dry, the open female flower stigma will easily dry up, shortening the time for the stigma to receive pollen. At the same time, the dry climate will also make the flower spike secrete too much honey, which is not conducive to the spread and germination of pollen and affects pollination and fertilization. Therefore, in the flowering period of litchi, it is necessary to spray clear water on the crown every morning to wash the ears, dilute honey and increase air humidity, so as to prolong the time for female flower stigma to receive pollen, promote pollen germination and promote fertilization.

3. Pollination by bees in flowering period: During the flowering period of litchi, bees can be used to collect honey to help pollination and improve the pollination effect. During litchi flowering, each acre of orchard is sprinkled with 1-2 boxes of bees to help pollination. For orchards seriously damaged by gall midge in previous years, special attention should be paid to collecting bees and spraying them after 70-80% female flowers wither.

4. Artificial pollination: In bad weather (dry days or rainy days), or in orchards with different male and female flowers for each litchi plant, when pollinators such as bees are lacking, artificial spraying of pollen water can increase pollination opportunities. The newly shaken male flower can be washed with clear water, or the blooming male flower spike can be directly washed in a dish with clear water until the water turns pale yellow, filtered, added with pollinating agent to prepare pollinating liquid, and immediately sprayed on the blooming female flower spike.

5. Artificial tree-shaking assisted pollination: In the full flowering period of litchi, if the weather is fine and there is a breeze flowing, shaking the plants or some local branches of the flowers will help the distribution and spread of pollen, help the trees and the downwind trees to increase the chances of receiving pollen, and at the same time shake the flowers and honey, so that the plants and flowers are ventilated and breathable, which is conducive to flowering and pollination.

The second is to protect withered fruits and reduce physiological fruit drop.

According to many years' observation, there are three physiological fruit drops during the growth of litchi fruit, and the fruit drops are concentrated: the first physiological fruit drop is about a week after flowering, that is, when young fruits are large and few, the main reason for fruit drop is poor pollination and fertilization; The second fruit drop is about 4 weeks after the flower withers (at the end of April or early April), that is, when the young fruit is as big as a finger, the main reasons for fruit drop are insufficient nutrition, unbalanced auxin, bad climate influence, pests and diseases, etc. The second fruit drop has the greatest influence on yield; The third fruit drop is about 7- 10 weeks after flowering (after mid-May), at which time some fruits turn to near maturity. The main reasons for fruit drop are the harm of pests and diseases, insufficient nutrition of trees, the influence of bad weather and the imbalance of auxin in trees. According to the causes of fruit drop, the first fruit drop (or female flower) can be effectively reduced by improving the pollination and fertilization rate of fruit ear at flowering stage. The second fruit drop (key point) and the third fruit drop can be aimed at the causes of fruit drop, and on the basis of applying strong fruit fertilizer, pay attention to the early stage of fruit drop ...

Question 9:2065 438+06 When is the full flowering period of litchi in Guangdong? 10, now.

Question 10: What if litchi doesn't bloom at flowering stage? If there is, it will bloom naturally. You mean no flowers, right? The weather is abnormal this year, and varieties such as Guiwei have not blossomed.
