Several aspects that should be paid attention to in orchid cultivation

Orchid cultivation in China has a long history, and predecessors have accumulated rich experience in orchid cultivation. It is necessary to master the experience of predecessors, absorb its essence and deeply understand: cultivation environment, planting materials, watering, fertilization and pest control. It is the five links of orchid cultivation management.

1. The choice of environment is more important. Whelan mainly grows under shrubs in subtropical forests, and develops the growth habit that orchids like semi-cloudy and semi-sunny, and like moist and ventilated. As long as we master the growth law of orchids and provide or create environmental conditions close to orchids, Cymbidium hybridum is suitable for planting all over the country.

2. Use of plant materials. According to the experience of cultivation in various places, orchids can grow well no matter what plant materials (including soilless culture) are slightly acidic. The problem is that different plant materials should adopt different management methods. It is best to use pottery pots or Yixing pottery pots for flowerpots, because orchids are aerial rooting plants, and the ventilation of flowerpots is very beneficial to the growth of orchids.

3. Rational watering is the key to raising orchids. The water for watering orchids should be clean and slightly acidic, and never water sewage with germs. The method of watering varies from plant to plant. Loose mountain mud contains enough water, and granular soil and rocky volcanic rocks absorb enough water, but there is no water accumulation. After different plants were watered once, the surface of the basin was dry and the plants turned white by about one centimeter. In order to raise the temperature, water can be sprayed on the surface of the basin to increase the water content of the planting materials in the upper water-rich basin, so as to keep the bluegrass and pseudobulbs moist to a certain extent, and then the whole basin can be watered before it is completely dried.

4. Fertilization: On the basis of mastering watering, fertilization is becoming more and more important in order to promote the better growth of Poa pratensis. Organic fertilizer, that is, farm manure, should be diluted every ten days, and other inorganic fertilizers (fertilizers) should be used according to the instructions. Foliage fertilizer can be topdressing outside the roots during the growth period of orchids. Base fertilizer is also very important. When turning over the pots and changing the soil, a proper amount of base fertilizer can be added without touching the orchid roots. Too much fertilizer can easily burn orchid roots and produce black spots. If fertilized properly, it can grow strong seedlings and flowers. Orchid fertilization is generally required to be small, thin and light, and it is really thin and diligent.

5. Pest control: Pests are easy to prevent, but fungal diseases are difficult to treat. If pests such as scale insects are found in bluegrass, they can be sprayed according to the instructions, and it is best to use them together, 2-4 times a year. General bacterial diseases can also be treated as black spots. According to the instructions, bactericides such as chlorhexidine, methylbutanazine and chlorothalonil can be used. During the growth period of 15-20 days, regular cross treatment and preventive spraying can be carried out. If Balasi soft rot (rotten coccidiosis) is found, it is an incurable disease of orchids. Once found, it can be removed in time. Therefore, when buying bluegrass, we must pay attention to the fact that we must buy diseased grass with lower price at home, which will affect other valuable bluegrass.

At present, with the increasing demand for orchids at home and abroad, the trend of orchids is quite promising, especially fine products, treasures and rare products. Therefore, the orchid market and the potential market of orchids are very broad, and there is still great room and prospect for the development of orchids. Therefore, we must correctly face, adapt and adapt to this gratifying situation. Fully protect the increasingly depleted orchid resources, master the growth habits of orchids, and make your own bluegrass better.

How to raise orchids indoors?

1, there must be a gentle wind blowing.

Wind can send away dirty air and sultry airflow, and bring fresh air at the same time. Throughout the ages, orchid families have emphasized the importance of ventilation as a height related to the survival of orchids. At present, indoor decoration materials emit a lot of harmful gases, and there is also domestic pollution in the room. It is necessary to open more doors and windows to make the air convection, and set up a ventilator when necessary to ensure the indoor air is fresh, which is the primary condition for raising orchids.

2, there should be sunshine and rain (simulation)

Plants nourished by sunshine and rain can thrive, and elegant orchids cannot do without sunshine and rain. Indoor, it is not enough for orchids to receive light only by part of the sunshine from the window and changing the pot position frequently, so lighting is needed to make up the light. Frequent micro-spraying simulates rain and dew, and sprinkling water on the ground creates a humid environment.

3, pay attention to breathable hydrophobic.

A choose blue pots (tile pots, sweat mud pots, etc.) with good air permeability and hydrophobic performance. )

B choose rough planting materials for cultivation (pond stone, fairy soil, ceramsite, etc. )

Build a blue frame and lift it into the air.

4, timely watering and fertilization.

Because it is cultivated with coarse plants, water is easy to lose, so pay attention to moisturizing and avoid being too dry. It is better to fertilize with long-acting slow-release fertilizer (magic fertilizer, etc.). ), supplemented by foliar fertilization.

5. Insecticide and sterilization

Insecticide and disinfection should be carried out regularly, and prevention should be done at least once a month. We should always pay attention to the growth of orchids, prevent pests and diseases in time, and avoid spreading.

How to raise orchids

"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. It is best to be outdoors in an open and humid place. There should be enough light indoors, preferably facing south. In this way, it is beneficial to orchid growth. It's best to put the basin on a 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. Erect leaf varieties from Xia Lan and Qiu Lan are best placed in the cool south to 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 best to be eight points dry and two points 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 northern areas, orchids are not too dry because the climate is too dry in winter and early spring.
