How to raise orchids in autumn

In autumn, when the temperature decreases, the growth of orchid plants slows down, the water demand decreases, and the substrate can be kept wet. In order to make the root grow healthily, the substrate should not be too wet and too fat. Too wet will damage the root system, which in turn will damage the whole orchid plant.

The root of orchid, fleshy, stout, not resistant to flooding. The preparation of loose and breathable matrix is the key to the cultivation of orchid root. The root has the characteristics of water and fertilizer. The following is to introduce to you-the main points of cultivating orchids next autumn:

Typhoon prevention in early autumn is a season of frequent typhoons. Special attention should be paid to making preparations for typhoon prevention, which must not be taken lightly, otherwise, the consequences will be unimaginable. I remember that in the autumn of four years ago, when a typhoon came, due to the failure to close the doors and windows of the orchid room in time, the ceiling of the orchid room was blown off, and the downpour washed out the orchid root; the typhoon passed, and the hot sun was in the sky in the next few days. because there was no time to repair and no good shade, my orchids suffered heavy losses, and several pots of undead orchids have not even recovered. Therefore, remind everyone: in the typhoon season, to attach great importance to check whether the orchid room sunshade net bundle is firm, orchid room ceiling, doors and windows are firm. It is best to design a plan: if the ceiling of the orchid room is blown off by a typhoon or strong wind, you can move the orchid to a safe place, and so on.

Shading and preventing the sun still plays the leading role in autumn. It can be said that early autumn is like summer and late autumn is like winter. The weather in early autumn is still hot and hot, and when it is sunny, it is no different from summer, and sometimes the temperature is higher than summer, so shading and sun prevention must be done carefully.

Third, disease control, pest control and scorched head (coke tip) autumn is also a high incidence season of orchid diseases and insect pests, and its harm momentum is greatly fierce (high) in summer, therefore, the prevention and control of orchid diseases and insect pests in autumn is the top priority of the whole orchid cultivation link, if a disease occurs, bluegrass will be scorched (coke tip), serious, will make the harvest of the harvest disappear,-year's painstaking efforts will also be in vain. Therefore, it is necessary to do a good job in the prevention and control of diseases and insect pests. Especially for diseases, more attention should be paid.

Fourth, timely watering to prevent dry and wet autumn wind and dust flying, which shows that the autumn climate is mainly dry, so the basin noodles of orchids dry very quickly at this time, especially orchids planted with mud pots and large grain plants, should be watered at the right time to prevent dehydration and dryness, but for strong grasses, water control can be carried out to promote flowers. Orchids raised with pearl sand flowerpots and plastic flowerpots should prevent them from getting too wet and eat hot roots, and pay special attention to orchid pots with fine plant materials and poor air permeability. At this time, the watering and shading of orchids are very important. If the water is impermeable and not in place, it will cause the orchid root to dry up and die. If the water is poured too much, the new orchid root will suffer from heat and pathological changes, which will cause inestimable losses. Skills and matters needing attention on how to cultivate orchids

Orchid is a kind of green plant with high ornamental value, and many people want to raise it at home, but people don't know much about its breeding methods, let alone what they need to pay attention to when raising orchids. Today, the editor will introduce these problems to you, so that you can easily understand how orchids should be raised.

How to grow orchids

1. Choose the right soil

Usually the choice of orchid soil is very important, it likes fertile soil, usually can choose humus-based humus or mountain humus soil, in addition, you can also go to the market to buy special orchid mud, and then add the right amount of vermiculite and perlite, prepare them into loose, aerated and permeable nutrient soil.

2. Temperature and light

Orchid culture in mild light is two very heavy conditions, usually it likes to grow in a warm environment, when the external temperature is about 20 degrees, it grows the fastest, when the external temperature drops below 10 degrees, it will stop growing. In addition, the orchid is a shade-loving plant. It should be placed in a cool environment in spring, summer and autumn, especially in summer. It must not be placed on the sunny south windowsill, otherwise its leaves will be burned by strong light.

Matters needing attention in culturing orchids

1. Pruning

When cultivating orchids, attention must be paid to pruning, especially when old and yellow leaves appear in orchids, they need to be cut off as soon as possible, only in this way can we promote the growth of new leaves, improve permeability and reduce the occurrence of diseases. However, when pruning orchids, special attention should be paid to the scissors used for pruning, which must be disinfected in advance to prevent infection.

2. Change the basin in time

When raising orchids, we should also pay attention to changing pots in time. Orchids grow slowly at the beginning, but they grow faster in the later stage, and their roots are well developed. they must change pots once a year, and when changing pots, they can put some tile grains at the bottom of the flowerpot, and then put them into the culture soil. after planting the orchid into the flowerpot, the orchid should be watered sufficiently, and the nutritive soil in the flowerpot should be compacted.

How to cultivate orchids in winter (scientific name: Cymbidium ssp.): epiphytic or terrestrial herbs, with several or more leaves, usually on the base or lower nodes of pseudobulbs, distichous, banded or rarely oblanceolate to narrowly elliptic, base generally with broad sheaths and enclosing pseudobulbs, articulated. Racemes with several or many flowers, the colors are white, pure white, white-green, yellowish green, yellowish brown, yellow, red, cyan, purple.

Master the following ten points: first, to master the correct time to enter the room; second, to spray disease and insect prevention drugs before entering the room; third, to pay attention to anti-freezing; fourth, to regularly ventilate; fifth, to prevent the basin soil from being too dry; sixth, to prevent the basin soil from being too wet; seventh, to prevent gas; eighth, to prevent overheating; ninth, to prevent wet leaves; and tenth, to waterproof and irrigate the heart of orchids. First, in order to prevent frozen orchids from overwintering, the room for raising orchids in winter can be a greenhouse (a glass room that can bask in the sun during the day) or a plastic shed, but the lowest temperature must ensure that the orchids are not less than 1 degree to prevent frostbite. If it is below zero, it is harmful to any orchid and can not freeze the orchid in any case. Use an electric heater to heat it up when it is too cold. Second, the cultivation of orchids in winter should prevent the raw flower pot soil from being too dry in winter, the orchids stop growing and the water demand is reduced, because the orchids are fleshy roots and generally can not die if the water is cut off, but if the pot soil is dry for a long time, it will lead to the strong orchid roots becoming empty roots. however, it will not be reflected from the orchid leaves for a while, such as the orchid roots have been seriously injured when reflected on the orchid leaves, and the serious ones have dried to death. This kind of problem often comes from an one-sided understanding of "winter is not wet". When you see the orchid is dry, it only moistens the water at the edge of the basin, and when you see the topsoil is wet, you think that the orchid has been thoroughly watered, causing Langen to dry to death. The correct way is "do not dry, do not water", "water is thoroughly". Too dry orchid pots can be soaked in water. Third, in order to master the correct time for breeding orchids in winter, our country is vast, and the temperature difference in the same season is very large, so the time of entering the room cannot be generalized. We should decide the time of entering the room according to the local climate change. I think if it is Chunlan, you can choose to enter the room the day before the weather forecast that it will be frozen tomorrow. Some people enter the room when it is less than 10 degrees. I think this is not conducive to the development of flower buds. Entering the house prematurely will lead to the decrease or even non-birth of flower buds in the next autumn, so as long as the temperature is not lower than the cold. Chunlan should let it carry out 10-0 degrees low temperature exercise, such a temperature can also make the orchid tissue more substantial, healthy, the next year new buds strong and powerful. Fourth, the cultivation of orchids in winter should be regularly ventilated in order to keep the orchids from freezing, and can not make the orchids in a place that is not ventilated for a long time, which will lead to the freezing of orchids and black spots on the leaves of orchids in spring. The correct way is to open the window and open the door in time when the temperature is high, to promote air convection, but to prevent the cold northwest wind, in addition to freezing, at noon can open the window to breathe. Fifth, in winter, orchids should be sprayed with disease and insect control drugs before entering the room. When the temperature is below 5 degrees, choose clear weather to spray 800 times the liquid of topzine or carbendazim. If there are mustard insects, you should also spray once cobalt oxide and other insecticides to prevent diseases caused by the high temperature in the greenhouse after entering the house. Orchids stop growing in winter, but the management of this period is directly related to the growth of the next year. Some people, due to improper management in winter, cause frostbite, frostbite, empty root and black spot, even to death. Therefore, every orchid farmer must pay attention to the winter care of orchids.
