Orchids turn pots and change soil in spring

The plan of the year lies in spring, and spring returns to the earth in the twinkling of an eye. Spring is the golden season for the growth of orchids in a year, and it is also a critical time for orchids to turn pots, ramet and germinate. At the same time, it is also the acceptance and summary of the dill achievements of the people who raised orchids last year.

The best temperature for orchid planting is 5-15 degrees. 10 degrees is the dormancy threshold temperature of orchids. Therefore, turning the basin at about 10 degrees has the least impact on the orchid, so the basin can be turned in the spring and autumn.

As the saying goes, "grow grass in spring, grow flowers in autumn, grow grass more, grow flowers less". This is the principle of turning the basin in mind by the people who raise orchids.

Generally speaking, turning the basin should be controlled in the spring and autumn, around the Qingming Festival in spring and around the Autumn Equinox in autumn. From the point of view of the basin, the orchid enters the winter dormancy period in autumn, and the time of resuming the basin is short.

When the orchid turns the pot in spring, the orchid will soon enter the vigorous growth period, so the spring turn is better than the autumn, the summer is hot, the winter is cold, it is the dormant period of the orchid. Turning the pots in this season is not conducive to the repots of orchids.

On the Internet, I have communicated with many orchid friends. With regard to the time between turning pots, most of them think that it is not good for orchids to turn pots and change soil frequently, and it would be better to change orchids for two to three years. Because orchids do not like to do 'sports' less turning pots can also make strong grass.

Turning over the pot and changing soil of orchids are closely related to personal cultivation habits, planting materials, management and so on. I am tilting to turn the basin once a year and replace the new plant material.

Sichuan orchid developed earlier, and the cultivation technology of national orchid can be regarded as second to none in the country. I am in the north, is a non-producing area, contact with friends and purchase of orchid seedlings, most of them are from Sichuan. In order to make Lan adapt to the northern environment as soon as possible. The selected plant materials and the regulation and management of the small environment are basically the same as those in Sichuan.

The choice of plant materials can be regarded as a minor detail in the process of raising orchids. But sometimes if it is not handled properly, there will be problems. Those who are light will fall into the grass and those who are serious will be wiped out. It is one of the key factors for the success or failure of cultivation.

Each person's choice of plant material varies according to the variety of orchid, the regional environment of cultivation and the degree of cognition of orchid cultivation. As long as it can cooperate with the personal cultivation environment and management to make the orchid grow healthily and healthily, any plant material can be selected.

Now write down the types and treatment methods, preparation ratio and planting process of the plant materials you use.

Species preparation ratio of plant materials

Subsoil; 70% of particles in burned soil, 30% of charcoal particles

Base soil: 10% of particles in burning soil, 25% of small particles in burning soil, 10% of particles in fairy soil, 25% of small particles in fairy soil, 20% of oak leaves, 10% of peat with charcoal and active soil.

Topsoil; put a layer of peat, active soil and Zhixiang near the pseudo-bulb, and then put a layer of small particles of burning soil.

Peat; also known as grass coal, or Vietnam. It is the product of biological decomposition of plants in swamps. However, because there are too many impurities to go through many times of washing, sterilization (now the finished product of fine washing) is very good for weak roots and tissue culture seedlings.

Before use, soak in boiling water, dry and cool, spray 500 times blue bacteria king.

Burning soil; made of natural clay, fired at high temperature, with hollow particles and many round pores on the surface. Therefore, it has good water absorption and water retention.

Before use, it should be often washed with water to make it absorb water, remove the fire and wash off the powder, and let it dry for use.

Fairy soil; also into peat, is trees, weeds and other organic matter, after thousands of years of decay, rich in humus, humic acid.

Soak for one or two days before use, wash off the powder and dry for semi-dry use.

Oak leaves and green bar leaves; wild orchids often grow in oak and green bar forests in nature. Their leaves, branches, bark, etc. are most suitable for the reproduction of cyanobacteria and other beneficial bacteria. Compared with the two, green bark leaves are much better than oak leaves, but because there are few trees, the price is relatively high. Oak leaves are usually used. Among them, the spiny oak leaves are the best.

It needs to be completely fermented before use, and there are only semi-fermented and fried ones in the market. If it's not urgent, in the summer. Can be oak leaves and a small inch of branches, black plastic bags, and there are yeast slices, fungicides, pesticides. The pile of water is sprayed wet and tied up and placed in the sun for a period of time to let it ferment. Use after complete fermentation. Yeast tablets can be fermented rapidly, and fungicides and pesticides can completely kill bacteria and eggs in oak leaves.

In case of emergency, you can use a high-pressure cooker for half an hour or cook for two hours to make the leaves feel a little soft.

Charcoal, especially the charcoal that has just been fired, contains a lot of activated carbon, has strong adsorption capacity, has disinfection, sterilization and bacteriostatic effect, preferably burned by trees, and the charcoal used for barbecue in the market is mechanistic and easy to powder. it contains sundries such as coal powder, which can not be used.

Charcoal has a bactericidal effect. So each pot can not account for 5% of the plant material ratio. The basin bottom is the best.

Planting should make full contact between Langen and granular plant material. There are many empty roots, but this aspect has not been properly dealt with.

First of all, the orchid plant, cut off the empty root, rotten root and cut root. Disinfection after the sun to Langen white, slightly soft and elastic when the best, must not be too dry.

When planting, first mix with the base material, put it into the bottom of the basin about 1/3, put the orchid in the basin. After the use of mixed foundation soil, while feeding while gently shaking the basin, you can also use chopsticks, up and down cuttings, so that Langen separate from each other and fully contact with the particles. Fill near the false bulb, you can use both hands to gently firm the basin on the ground, so that there is no gap around the orchid, put a layer of peat, active soil, plant Xiang after a layer of burning soil particles. The false bulb is required to be in line with the mouth of the basin. The plant just covered the false bulb and made it into a steamed bread shape. Wash the orchid leaves with water spray, pour water thoroughly, and restore the basin in a cool and ventilated place. In addition, the plant particles cultivated now are generally relatively large, so we must pay attention to planting seeds when we put them on the pot to prevent the nest roots.

I tilt to turn the basin and change the soil every year. It has a lot of advantages.

one。 Summing up the experience and turning the basin every year, we can see the sturdy roots and the growth of orchids. Summarize the gains and losses of fertilizer, water and orchid management experience in the past year. In case it is adjusted in time in the coming year. At the same time, in the process of turning the basin, clean up the empty roots, comb the old roots, and reduce the hotbed of pathogen breeding. The replacement of plant materials and the selection of orchid pots are carried out at the same time.

two。 Replacement, loose planting material

1. If the orchid mud raises the orchid, turning the basin every year can prevent the consolidation of the basin soil and prevent the orchid root from suffocating the orchid root due to the basin soil consolidation, or the phenomenon that the orchid can not be watered to dry the orchid.

two。 If it is granular plant material and disease-free, do not want to change the new plant material, you can turn the basin to comb the orchid root to dry until the blue root is white, slightly soft and elastic, plant it with the old soil, which can ensure the wetness of the lower part of the potted soil.

After a year of growth. The plant material in the basin forms a certain waterway every time it is watered, a large amount of water rushes down along the gap in the basin wall, which looks like it has been watered through from the outside. In fact, it was just the surface of the topsoil and the basin soil below, which moistened and dried quickly. Can not meet the needs of the growth of Langen. In this way, the orchid root of the orchid is horizontally long, and the lower part of the original strong root is empty because of the loss of water. Therefore, the orchid is getting weaker and weaker.

three。 Substitute pesticide

Changing new plant material every year helps to prevent the resistance of orchid from weakening due to acidification of plant material. New plant materials can replace pesticides, reduce the use of fertilizers and drugs, reduce plant resistance to drugs, and kill three birds with one stone.

four。 Increase the germination rate

There are many good varieties of orchid, the germination rate is low, often three or four seedlings. Turning the pot every year makes the orchid have a sense of crisis and can improve the germination rate to a certain extent. For example, if you soak the root with blue fungus king, promoting root and other commercial fertilizer for an hour, the effect is more obvious, not only to improve the germination rate, but also to sprout.

five。 Reduce loss

Proper ramet. It can reduce the risk of death due to disease, so that the whole pot will not die and precious orchid varieties will be lost. (you can't put all eggs in one basket.)
