Do you like orchids? Have you ever had orchids? Many people who like to raise orchids know that there is a proverb for raising orchids, called three seeds, seven branches. This means that orchids management is very important. If they are not properly managed at ordinary times, orchids will have various problems, so how to manage orchids correctly? The small series introduces you to the management points of orchid conservation.

The four correct management points for orchid conservation

1. Different lighting at different times

Orchids need to be maintained indoors in winter, spring, summer and autumn should be planted under shade. If the light is suitable and the fertilizer and water are appropriate, they can grow green leaves and flowers. Shed shading best can think of the freedom of adjustment, can not cover too old-fashioned, generally morning and evening when to open, so that orchids absorb dew. Orchids generally need to grow in a half-shade and half-sun lighting conditions, especially in its flowering period, more need to be carried out under cool and humid conditions, so as to extend the ornamental time of orchids. Generally, at the end of autumn, orchids will be given strong light, and in winter it is best to place orchids in places with more strong light to facilitate orchids growth. Orchid leaf structure color depends on light, general mesophyll hypertrophy, yellow green or spotted leaves need more light, and thin leaves and dark green leaves need less light. Cymbidium and cymbidium need strong light, while cymbidium and cymbidium need weak light.

2, the season is different humidity is also different

Orchids love a humid environment, but the pot soil requires drought, so you can sprinkle water on the ground and pot soil every day to increase the humidity around you. Watering should not be too much, basically keep seven points dry, winter should be kept slightly dry, pot soil slightly dry, can make plant nutrition concentrated, conducive to flower bud differentiation, too wet is easy to make orchid leaves grow, even rotten roots, so the lower part of the orchid pot should be filled with broken bricks and charcoal blocks to facilitate drainage; before flowering, watering can not be sprayed on the scape, no deletion will rot bud. In short, the spatial humidity required by orchids is more important than root humidity.

3. Management points of orchid pot replacement

Because orchids grow slowly, new roots and new leaves are only produced once a year, so it is generally necessary to wait until two years later. When dividing pots, the soil should be fully dried. If the fleshy roots of orchids are slightly wilted, the seedlings should be poured out, then the old soil should be shaken off, and then the diseased roots, old roots and broken roots should be cut off. Even if the plants are cultivated without roots, there is no need to worry. After pruning, they should be washed with water. Then divide the orchid seedlings into 2-3 clusters, pay attention to at least 3 false bulbs in each cluster, apply furnace ash or sulfur powder on the wound part of the orchid seedlings, then place it in a cool and ventilated place, wait until the roots are slightly dry, white and soft, and then plant it in the basin soil with heavy sand content. The reserved orchid roots should be placed in the basin naturally, and the new buds should be outward, so that its growth and development leave room. Pay attention not to planting too deep. It is advisable to ensure that half of the false bulbs are exposed.

4, orchid growth process pest control

Physiological diseases of orchids can be observed and mastered from subtle changes in leaves: generally yellow and thin leaves, is the phenomenon of lack of fertilizer; from the tip of the leaf gradually downward scorch, is caused by excessive fertilization or fertilizer application, and leaves from bottom to top scorch, is caused by excessive watering; from the middle of the leaves yellow or black spots, or even scorch, is caused by excessive difference between soil temperature and water temperature.

The above is about the management points of orchids, we in the maintenance of orchids, the above four aspects of management should be done well, so that you can grow vibrant orchids oh, love orchids you must not ignore these management points.

How can orchids be better maintained? New Techniques for Orchid Conservation and Management

Orchids how to grow, this site has been detailed, then orchids how to better conservation? Do you know all about new orchid conservation and management technologies? The next small series will introduce you in detail how to better maintain orchids? Orchid conservation management new technology to help everyone better grow orchids.

New technologies for orchid conservation and management:

Orchids must be placed in sunny places, especially in cold winter, to create a better growth space for orchids.

Change pots must be timely, not only to maintain the space for orchid growth, but also to ensure the fertility of the soil after changing pots, so that orchids can better absorb nutrients and grow better.

The best growth temperature of orchids is 3-10 degrees above, otherwise orchids are easy to freeze, so when the temperature is low, we must pay attention to warm measures, but also spray fertilizer before the temperature is low to maintain the temperature of orchids themselves, the impact on cold weather will be reduced.

Orchids must be planted in different species separate, otherwise different species will affect each other.

How to maintain orchids in summer and autumn? Orchid Summer and Autumn Conservation Guide

How to maintain orchids in summer and autumn? Orchids can also be called Chinese orchid, spring orchid, orchid grass, orchid, orchid, white, white green, yellow green, yellow, pale brown, yellow and so on. Orchids like shade afraid of sun, avoid hot, dry, planting requires a good ventilated environment. Therefore, it is possible to carry out summer and autumn conservation management according to this habit of orchids.

1. Shade and ventilation

Orchid planting from early summer to the end of September should be shade, the shade should not be less than 70%. Shading large amount of use shading net, small amount placed in the north balcony, eaves. During this period, the plants should be scattered, the pots and pots should not be less than 10cm, and the bottom of the pot should be supported with bricks, which can increase the ventilation and make it ventilated. In addition, it is necessary to prevent the pollution of harmful substances such as sulfur dioxide, hydrogen fluoride and dust, and promote its healthy growth.

2. Cooling and humidification

Orchids suitable for growth temperature of 20-28 degrees, when the temperature is above 25 degrees grow rapidly, more than 32 degrees will enter the dormant period. When the temperature reaches 30 degrees, cooling and humidification measures should be taken. Orchids can be cultivated in the open air, and river sand or plastic film can be laid on the ground. Persimmons on the balcony can be sponged under the basin, and they are often kept moist. At the same time, spray plants and sprinkle water on the ground throughout the day. Indoor farming can be cooled by air conditioning or fans.

3, watering and fertilization

At present, the vast majority of orchids are cultivated in soil, and more are potted plants. The water content of the basin soil should adhere to the principle of "moistening but not wet, dry but not dry". Water when the topsoil is slightly white. Do not water too much. From midsummer to early autumn, water once in the morning and water at night according to the dry and wet degree of the basin soil. If the soil is dry at noon, it should be replenished with water at any time. After mid-autumn, the climate is getting cooler, but the air is dry. According to the requirements of "autumn is not dry", keep the basin soil moist. Orchids should be fertilized according to the principle of less quantity, thin, frequent watering and timely. From May to September, fertilizer should be applied according to different orchid species and different growth stages. Liquid fertilizer is generally applied once every 15 to 20 days, with a ratio of fertilizer to water of 1:10, and solid fertilizer is used indoors. Scale production of multi-purpose fertilizer, concentration of about 0.1%. Foliar fertilizer concentrations are formulated according to product specifications.

4. Disease prevention and pest control

Orchid anthracnose can be controlled by carbendazim and thiophanate; white silk disease can be controlled by spraying chloramphenicol injection 500~1000 times; scale insects can be manually removed and sprayed with drugs during larva incubation period in May-June; aphids and whiteflies can be controlled by spraying 10% wettable powder 500 times.
