Greenhouse insect net, considering the problems related to pesticides and increased costs, any modern greenhouse does not have adequate insect barriers. Properly installed anti insect net can prevent insects from invading and provide the greatest possible air circulation, which is essential to achieve optimal crop yields.
Insect protection net the air intake holes will have a significant effect, but all greenhouse openings, including access doors (and double screen doors), should be screened for best results. Insect proof net in order to prevent insects from entering the greenhouse, we usually install anti insect net mesh in the ventilation holes. It can keep insects away from growing areas and protect plants without the use of pesticides or alternative pesticides. This is a way of environmental protection, which is conducive to the sustainable development of agriculture.
In order to meet the needs of different plants, agriculture net have three types of insect barrier net. One is silver gray or aluminum foil, which has a good effect on repelling aphids and can lower the temperature of the greenhouse. The second type is white, its light transmittance is much better than silver gray, and it is more versatile. It is suitable for photosensitive plants, but in summer, it will increase the temperature of the greenhouse. The third type is black, which can have shading and cooling effects.
Installing insect netting at the vents of the greenhouse will significantly increase the ventilation resistance. It is necessary to install it and keep the temperature of the greenhouse monitored during the occurrence of pests. When the pest period has passed, it is best to remove it.
If the pests and diseases occur during the same period as the greenhouse requires ventilation and cooling, it is best to pay attention to the following points:
1. Increase the insect exclusion netting area or ventilation area to ensure adequate ventilation. Replacing rigid polyethylene walls with nets and polyethylene films is a good natural ventilation method to increase the ventilation rate.
2. For a ventilated greenhouse, only a protective net can be installed in the ventilation holes;
3. Keep the surface of the inspection net clean.
