The weather in Qingyuan in August

Speaking of bluegrass and orchids, you may often hear, what is the difference between bluegrass flowers and orchids? It is very difficult to breed bluegrass. Many people breed bluegrass and die for no reason. So, what are the breeding methods and precautions of bluegrass?

The difference between bluegrass and orchid

Many flower lovers have the same question, how to distinguish orchids from bluegrass, the same plant, some people call orchids and some people call bluegrass, which statement is correct? In fact, this is just a conventional name.

In China, many people are used to calling orchids orchids. At first, they specifically referred to China orchids, such as Cymbidium hybridum and Cymbidium hybridum. Later, Cymbidium hybridum entered China, mainly Cymbidium hybridum, which is one of the varieties of orchids. Many people also call it an orchid. In fact, they are all members of the same family, and they all belong to Lancome. Because there are too many varieties of Orchidaceae, few people subdivide them now, and they are basically common. Some people directly call orchids that have not yet blossomed "bluegrass" to distinguish them from orchids.

The following are the customary standards for distinguishing bluegrass from orchids in China.

Bluegrass is a small flower of grass, which is light, thin and has a little fragrance. There are many varieties of bluegrass.

Common bluegrass:

Chunlan: It is distributed in most provinces and regions south of the Yangtze River in China.

Rough leaves, fleshy roots, serrated leaves, and an inconspicuous pseudobulb at the junction of roots and leaves.

Spring blossoms, flowers overflowing, one for two.

It is a group of orchids in China.

Cymbidium sinense: It is distributed in Taiwan Province, Fujian, Guangdong, Guangxi and other provinces in China, with tender, broad and smooth leaves, fleshy roots, inconspicuous bulbs and serrated leaves.

Many flowers, spring flowers, fragrant or slightly fragrant.

Spring sword: distributed in Guizhou, Yunnan, Sichuan and other provinces, with sparse population, rough leaves and obvious ribs. Most leaves are hard and straight with fleshy roots (the new roots are twice as big as Chunlan).

The leaves have serrated edges, the bulbs are not obvious, and they bloom in spring.

Many flowers, fragrant flowers.

Four-season orchids (Xialan and Jianlan) are distributed in most provinces and regions south of the Yangtze River in China, with tender and smooth leaves, serrated leaves and fleshy roots. There is an obvious pseudobulb at the junction of roots and leaves.

Flowers bloom three times a year, in June, July and August respectively.

Many flowers, fragrant flowers.

Orchid (Ying Ge Green, Douban Orchid): It is distributed in most provinces and regions south of the Yangtze River in China, with long and narrow leaves, roots as big as spring swords, serrated leaves and inconspicuous bulbs.

Spring flowers, single petals, petals hypertrophy.

Most flowers are neither fragrant nor light.

Song Chun (Orchidaceae): The leaves are rough, with obvious ribs, leaf shape, fleshy roots and serrated edges. In addition to new buds, two or three new leaves will grow in the center of the old plant every year until 18 leaves are mature.

Flowers bloom in March and April.

Many flowers, fragrant flowers.

Lotus: distributed in western Yunnan, mountainous areas of Taiwan Province Province and a few areas of Sichuan.

Lotus root leaves are thin and narrow with small pseudobulb, with a diameter of about 65438±0cm and a root diameter of about 0.5 cm.

Pedicels are erect, slender and tall, with strong aroma in1-March.

Cicada (pig excrement bean): semi-epiphytic, with wide, thick and long leaves, serrated leaves, semi-fleshy roots and branches.

Many flowers, big flowers, flowers are not fragrant or slightly fragrant.

Flowers bloom in March and April.

Cold orchid: the leaves are tender and smooth, the upper edge of the leaves is serrated, the bulbs are not obvious, the fleshy roots are flowery and the flowers are fragrant.

The flowering period is September and 10.

Orchids, belonging to Orchidaceae, are monocots and perennial herbs.

Height 20-40 cm, long cylindrical roots.

Leaves clustered from stems, linear-lanceolate, slightly leathery, 2-3 in bundles.

Racemes, perianth in 2 whorls, fleshy, inner whorl.

Of the 3 petals, 2 petals are upright, the lower petal is lip-shaped and rolled outward, with or without purple spots on it. Stamens and styles combine to form Gynostemma pentaphyllum, and the color ranges from yellow-brown to light yellow, and the solid color without brown is the most precious.

The budding fruit is triangular and there are few kinds.

Orchids are usually divided into China orchids and orchids. Orchids in China are mainly produced in the subtropical region of Asia, mainly in the mountainous areas of the Yangtze River valley in China, and also distributed in Southwest China, South China and Taiwan Province Province. Orchids are mostly produced in tropical and subtropical forest areas.

Orchids from China have been cultivated in China for more than 1000 years, which is of great ornamental value: the leaves are evergreen and the flowers are fragrant and natural, so they are called "fragrance" and "national fragrance".

Cultivation methods and matters needing attention of Poa pratensis

Compared with other flowers, orchids are more difficult to raise.

The difficulty is that the roots of orchids are very sensitive to water, either "drowning" or "dying of thirst".

When the plant material is too wet or too dry, it will cause rotten roots or empty roots. If it lasts for a long time, the root problem will be reflected in the leaves and the plants will wither and die.

Because the pseudobulb of the orchid itself contains water, and the residual part of the root of the orchid still has a little water absorption function, even if the root of the orchid has problems, it can still stay for a period of time, so it is not easy to find problems from the aboveground part of the plant in time.

In fact, orchids are mostly drowned, that is, due to improper selection of planting materials, too strong water retention or frequent watering, the planting materials are always wet.

When this wet state lasts longer than the tolerance limit of orchids, the roots of orchids will rot and orchids will eventually die.

In addition, some people have heard that orchids are "afraid of water", so they seldom water them. As a result, overkill, orchids "thirst". This is also the case.

It can be seen that whether the water content in planting materials can be controlled well is the key to the success or failure of orchid cultivation.

"Three-point planting and seven-point cultivation" is the experience of ancient people in cultivating orchids.

The quality of conservation is related to whether orchids flourish or not, so it is reasonable for predecessors to attach great importance to this.

The following details the maintenance and management methods of orchids.

I. Place

The location of orchids is very important, which directly affects their growth and development.

Orchids are generally placed in the open field in spring, summer and autumn (in the open shade in summer) and indoors in winter.

The outdoor space should be clean and the air should be humid.

There should be enough light indoors, facing south.

In this way, it is beneficial to orchid growth.

Put the basin on the wooden frame or table, not on the ground.

Second, shading

Orchids are mostly semi-negative plants, and most varieties are afraid of direct sunlight and need proper shade.

Orchids can get more sunshine in the first half of April to promote their growth.

Appropriate shade should be provided after the end of April.

Varieties with erect leaves in Xia Lan and Qiu Lan are placed in the cool south, which makes them get more sunshine; Qiu Lan and Chunlan with drooping leaves should be exposed to the sun for two hours every day.

Shade early every day from June to September. If a reed curtain is used, a dense curtain or two-layer thin curtain can be used.

After 10, the weather turns cold and the sunshine is weak, so the shading of vegetables can be postponed, but attention should still be paid to shading around noon.

Third, rain protection.

Orchids can rain lightly, but we should avoid mildew rain, showers or even rainy days.

In the rainy season, it is particularly necessary to do a good job of rain protection.

From late June to mid-September, showers are frequent.

If it rains for a short time and the rainfall is small, water it more at night to discharge the hot air in the basin, otherwise it will damage the orchid and even rot its roots and die.

If the sun shines after the rain, it should be shaded in time to avoid the influence of the rising heat on the growth of orchids.

The rainy season is the stage when orchids grow leaves. If the pot soil is too warm, it will lead to bad growth of leaves or cause diseases.

At this time, a small amount of plant ash can be sprinkled to adjust the humidity of the basin soil.

Fourth, water.

The flower proverb says that "dry orchids wet chrysanthemums" has some truth.

Generally speaking, orchids are eight parts dry and two parts wet.

If it is too wet, it is easy to make flowers rot and die.

The principle of watering should be: water when it is dry, stop when it is wet, and dry when it is suitable.

When mastering the details, it is generally necessary to pay attention to watering more during the growing period (the end of May-June), watering less during the germination period (about March-April) and flowering period (about March-April), and watering less or not during the dormant period (winter).

If the flowerpot is big and the orchid plant is small, water less; if the potted plant is big, water more.

Water more when the climate is hot and dry, and less or no water when it is cold and humid (such as rainy season).

If the roots of orchids newly dug from the mountains are sparse or broken, they should be watered less to make the soil dry, so as to avoid root rot and be conducive to pumping new leaves.

As the ancients said, the experience of "dry in autumn and not wet in winter" well summarized how Chunlan and Xia Lan watered.

But in some areas in the north, orchids are not too dry because the climate is too dry in winter and early spring.

Watering time: it is advisable to water orchid leaves after sunset in summer and autumn, so that they can be dried before nightfall, or watered in the morning; It is best to water before and after sunrise in winter and spring.

It is not allowed to irrigate with cold water suddenly after the sun burns, so as not to lower the soil temperature, affect the water absorption of roots and interfere with the physiological balance.

The amount of watering should not be too large to inhibit the occurrence of diseases.

Watering method: water should be poured from the pot, not into the bud, so as not to cause rot.

The above is the difference between bluegrass and orchid, the breeding method of bluegrass and the relevant contents of matters needing attention.

It can be said that bluegrass is one of several plants that are difficult to raise, which tests everyone's reproductive ability very much!
