How to manage Hot Pepper in greenhouse in Winter

Pepper planting area in our country is very large, because now the planting technology is more and more mature. So peppers can now basically be grown all year round. When pepper is planted in winter, it is mainly planted in greenhouses. In winter, we need to do a good job of management when planting pepper in greenhouse. So how should winter greenhouse peppers be managed? Today's small series will give you a brief introduction. Let's take a look at it together.

1. Temperature and humidity management

In winter greenhouse planting pepper, the first management point is to pay attention to control the temperature and humidity. Because in winter, the temperature is very low and the ground temperature is not high. Pepper plant growth is weak, easy to appear excessive growth, slow growth of growth points and other phenomena. It affects flower bud differentiation, leads to abnormal fruit growth, and the fruit setting rate will decrease accordingly. Therefore, we should pay attention to raising the temperature. The temperature should be kept at about 30 degrees during the day and about 15 degrees at night. Then pay attention to the humidity in the shed, try to release air and reduce humidity during high temperature, avoid excessive temperature in the shed, and adjust the watering interval.

2. Cultivation management

Pepper cultivation in winter is considered anti-seasonal cultivation, so winter pepper cultivation management is very important. In particular, attention should be paid to foliar fertilizer topdressing, in order to promote bud growth, improve fullness and fruit setting rate. Foliar fertilizer should be sprayed properly. Foliar fertilizer can be sprayed with plant growth rejuvenating agent, phosphorus and potassium power mixture, about once a week or so, about three times. According to the growth of plants, compound fertilizer and other fertilizers should be applied reasonably, and fruit thinning should be done well. Abnormal fruits, over-dense fruits and rotten fruits should be removed and picked in time to avoid falling trees.

3. Fertilizer and water management

Although the winter temperature is low, we still have to pay attention to watering. However, it should be watered in sunny days, mainly with small drops of water, not too much watering to avoid freezing damage. If it is not sunny, then it is best not to water to avoid unnecessary losses. Then fertilization work is also indispensable, winter watering and fertilization are generally to raise roots as the main purpose. Therefore, we should pay attention to control the amount of fertilizer according to the growth of pepper and fruit setting rate, and do not use high potassium fertilizer to avoid fertilizer damage.

4. Disease prevention

Because the temperature in winter is very low, the greenhouse will basically be more tight, and there will not be too long air time every day. The humidity in the greenhouse is easy to increase, so it is easy to have various diseases. Therefore, we should pay attention to the prevention and control of diseases, mainly based on prevention. In addition to high temperature ventilation work, but also pay attention to moisture reduction, watering to small drops of irrigation, can not expire frequently watering. And to combine drugs for prevention, common diseases are gray mold, cotton blight, etc., we must pay more attention.
