How to arrange insect proof nets in greenhouses when planting vegetables in hot and sunny weather

Firstly, it is necessary to manage the planting greenhouse well. Timely cooling and shading can help prevent vegetable burns. Adding shading nets in a timely manner can reduce the amount of sunlight inside the greenhouse, effectively reducing sunburn injuries. Strengthening ventilation and opening all air vents in the greenhouse can help release hot air as soon as possible. It can also be humidified and cooled by frequent watering and frequent spray. 2. Careful use of hormones is not conducive to vegetable cultivation and growth. Many greenhouse vegetables have abnormal fruits due to excessive use of hormone substances in high temperature weather, which affects the normal differentiation of flower buds and hinders the growth of various organs. Therefore, the use of hormones should be strictly controlled in summer.

In addition, we need to strengthen the pest control work of greenhouse insect nets and take various measures to prevent and control pests, which is an important task at this stage. For example, in summer, insect proof nets with a mesh size of 80 or more should be installed at the two air vents of the greenhouse, and sticky insect boards can be hung inside the greenhouse. Once pests are detected, timely control measures should be taken.
