1、 How to deal with Han LAN just bought it
The cold orchid just bought back can be spread out and dried to check whether the root is rotten. If so, it needs to be cut off with scissors. Then soak the root of the plant with 5% potassium permanganate solution for half an hour to sterilize the root of the plant. After soaking, put it in a ventilated place to dry, and finally select the appropriate basin soil for basin p>
2、 Specific breeding methods
1. Soil: you can choose a more fertile soil for breeding Hanlan. When planting, you can choose the high pots. In the basin 1/3, use coarse bricks and foam plastic blocks to fill the bottom. In the middle, mix the red soil and the brick and sand into 1/3. The upper part is mixed with a small amount of humus soil with the grain size of the sand. p>
2. Watering: it likes to be wet and avoid being dry. It is not suitable to pour too much water when you just bought it. You can pour water every 3-5 days and spray water on the leaf surface every day to ensure the humidity of the soil. It should be noted that each watering must be thoroughly watered, but the basin soil cannot be allowed to accumulate water, otherwise the root of the plant is likely to rot p>
3. Temperature: it likes a relatively warm environment. When it first comes back, it can be maintained in an environment with a temperature of about 24 ℃. If the temperature exceeds 35 ℃ in summer, it will grow poorly, so shading and cooling treatment is needed. Under normal circumstances, its optimum growth temperature is 15 ℃ - 30 ℃. In winter, when the temperature is lower than 5 ℃, it will affect its growth ability. At this time, it will be in a dormant state. Therefore, certain thermal insulation measures should be taken in winter so that it can survive the winter safely p>
4. Light: it likes shade and avoids direct sunlight. Too strong light can easily lead to leaf sunburn and sunburn. When you just bought it, you can put it in a semi shady environment for maintenance and give it scattered light appropriately. However, it is also not allowed to be excessively shaded or placed indoors for a long time, which is easy to cause poor plant growth and difficult to blossom. Under normal circumstances, more sunlight can be seen properly under the condition of ensuring that the plant leaves are not burned p>
5. Fertilization: it doesn't need much fertilizer. During the slow basin period, it doesn't need fertilization at all. Under normal circumstances, fertilizer can be applied 2-3 times a month, and potassium dihydrogen phosphate and orchid king can be used alternately as foliar fertilizer. During the growth period of new buds, an appropriate amount of urea can be added, and high potassium fertilizer can be sprayed two to three times during the maturity period of new seedlings. We can apply thin organic fertilizer once a month from April to June and from September to October, and avoid applying thick fertilizer to avoid fertilizer damage p>
