How to raise Daxuesu Culture methods and matters needing attention

In fact, Da Xue Su is also a variety of orchids, it is different from other orchids, it is special, its leaves are broad, and its flowers are white and plain, like heavy snow, very beautiful, so it gets its name, so what is the breeding method of Da Xue Su, and what do we need to pay attention to in the process of breeding?

How to raise Da Xue Su

1. Selection of basin

The pot is the relative space for the growth of orchids, and its material, size and shape should be selected according to the growth habits and root conditions of orchids. The root system of the orchid plant should be taken as the reference object, and the basin body that can allow the root system to be placed naturally should be the most suitable, so it is called "looking at the root and selecting the basin".

When planting big snow, the basin should be slightly larger, because the wide-leaf lotus petal needs more nutrients.

2. Placement position

The place where orchids are placed is very important, which directly affects the growth and development of orchids. Heavy snow is generally placed in the open field in spring, summer and autumn (shaded in the open field in summer) and indoors in winter.

It is best to be open outside, the air is moist, and there should be enough light indoors, preferably facing south, where orchids will grow. The orchid basin had better be put on the wooden frame or table, not on the floor.

3. Shade

Daxue can shine more sunlight to promote its growth in the first and middle of April. It should be shaded properly after late April, from June to September, every day should be shaded early, such as Reed curtains can be used with dense curtains or two layers of thin curtains. After October, the weather turns cool and the sun is weak, which can postpone shading, but we still need to pay attention to shading around noon.

Culture methods and matters needing attention of Daxue element

I. Culture methods

1. Temperature and light

The suitable temperature for the growth of Daxue is between 15 and 28 ℃, and the temperature in winter is not lower than 0 ℃. It is generally safe to survive the winter. When the temperature is more than 30 ℃ in summer, it is necessary to prevent heat and cool down, and the maximum temperature should not be higher than 35 ℃.

2. Humidity requirements

The humidity requirement of large snow element mainly refers to two aspects, air humidity and basin soil humidity, which is higher than that of other orchids, keeping it at 60%-80%. But it still needs a better ventilation environment, it should not only create conditions to increase air humidity, but also strengthen the ventilation of the cultivation environment.

3. Soil requirements

When planting snow, the soil generally contains humus-rich soil, the soil should be rich in humus, more mixed with some bark, leaves, peanut shells and other organic matter, the amount of these organic matter should not be less than 30%.

4. Fertilization

Daxue is relatively fond of fertilizer, so it is necessary to apply more fertilizer in the peak growth period. if the soil is fertile, you can reduce the amount of fertilizer and apply some foliar fertilizer. Plant fertilizer cannot be used directly, it must be fermented before it can be applied.

II. Points for attention

1. Keep the humidity of the air and pay attention to the humidity of the basin soil.

2. The growing environment of Daxuesu is relatively wet, so we should pay attention to daily insecticide and sterilization to prevent and control diseases and insect pests.

The cause of heavy snow leaf yellow

1, normal metabolism: generally after a period of growth, new leaves gradually born, old leaves will be metabolized. The gradual yellowing of old leaves is a normal phenomenon, and there is no need to worry about affecting the normal growth of Daxue.

2. Hot sun exposure: plants with heavy snow will be burned if the sun is too strong, especially after heavy rain in summer, which can easily lead to yellowing of leaves.

3. Improper management of water and fertilizer: too much water and fertilizer will not work, which will affect the overall development of Daxue, make the leaves grow badly and turn yellow.

The solution of heavy snow leaf yellow

1. Pruning: generally, the leaves caused by normal metabolism turn yellow, so there is no need to worry, just trim the yellowed leaves to keep the appearance of Da Xue Su beautiful.

2. Pay attention to water control and ventilation: in the normal growth of heavy snow, we should pay attention to control watering and ventilation to avoid diseases caused by excessive air humidity and leaf yellow.

3. Rational fertilization: control the amount and times of fertilization, apply fertilizer thinly, and replenish the missing elements in time. Due to the phenomenon of yellowing of leaves due to improper fertilization, you can remove the soil to the basin, replace it with new culture soil, replant it, water it once, and put it in the semi-shade to slow down the seedlings. After its growth resumes, thin liquid fertilizer or compound chemical fertilizer is applied.

Big snow is very good-looking, it can watch the leaves and flowers, but if there is a leaf yellow phenomenon, but it will affect its beauty, so when there is this phenomenon, we have to find out the reason, symptomatic treatment, will quickly recover, in fact, the general leaf yellow is caused by water, fertilizer, pruning and other factors.
