Due to the relatively closed environment of the soil wall greenhouse, soil wall greenhouse planting is more prone to diseases and insect pests than open-air planting. Therefore, soil wall greenhouse manufacturers suggest that it is necessary to do a good job in the prevention and control of crop diseases and insect pests in soil wall greenhouses.
(a) Regularly check the growth of crops grown in the soil wall greenhouse to keep up with the growth of crops. When pests and diseases are available, you can learn about them as soon as possible. During the inspection, use a multi-sided earthen wall through every corner of the greenhouse to check the back of the leaves, as the back of the leaves is usually a place to hide pests.
(2) For some special crops, fungicides must be used preventively. Only a small amount of fungicide can solve this problem and is more cost-effective.
(3) Pests not only cause harm to plants through feeding, but also spread a variety of plant viruses. The insects that cause huge economic losses are flower thrips, which can be monitored with yellow and blue armyworm plates. Monitoring the density of pest populations in soil wall greenhouses allows for an understanding of pest species and their densities.
(4) In the earthen wall greenhouse, only healthy seeds, seedlings or other breeding materials are planted, and no diseases and pests shall occur. Seed seedlings must be purchased from skilled and reputable production units and ensure that they are free of pests and diseases.
