What are the application functions of insect control nets in the forest and fruit industry
1. Insect control effect of insect net
Covering the fruit trees during the whole growth period, the adult pests cannot fly in, and cultivating fruit trees in summer can basically avoid the cabbage caterpillar, diamondback moth, cabbage armyworm, Spodoptera litura, yellow warped flea beetle, ape leaf beetle, aphids and other pests. harm.
2. The disease prevention effect of insect net
The disease prevention effect of fruit tree insect control net is mainly reflected in effectively inhibiting the invasion of pests, and at the same time cutting off the transmission route of viruses, reducing the occurrence and harm of virus-transmitting insects, and the ventilation in the insect net is good, which also inhibits some bacteria to a certain extent. Sexual and fungal diseases occur.
3. The shading and cooling effect of the insect net
Excessive sunlight will have negative effects on fruit trees, accelerate metabolism and accelerate decline. After the insect net is covered, part of the light can be blocked, so that the crops can get the light needed for photosynthesis. Generally, the shading rate of the white insect-proof net is 15% to 20%, and the white insect-proof net has the effect of scattering light when the light passes through, making the light in the net more uniform and reducing the lack of light on the lower leaves caused by the blocking of the upper branches and leaves of the fruit tree. phenomenon, which improves the utilization rate of light.
4. The anti-disaster effect of insect nets
The fruit tree insect-proof net is made of high mechanical strength. Heavy rain or hail falls on the net. After impacting and re-entering the net, the impact is buffered, thereby effectively reducing the impact of heavy rain and storms and other disasters on crops. At the same time, the insect net also has a certain anti-freeze effect.
5. Insect-proof nets save labor and cost
Although the shading effect of the sunshade net is good in production, it is not suitable to cover the whole process due to too much shading. The insect-proof net has less shading, can cover the whole process, and can be used to the end, saving labor in management. After the application of the insect-proof net, the fruit trees can be completely free of insecticides and pesticides during the whole growth period, which controls the pesticide pollution, and saves the labor of pesticides and spraying.
