Application of insect-proof net in forest and fruit industry
Insect nets have many applications, and they are also widely used in fruit planting. Because of the high-efficiency anti-insect effect of the anti-insect net, it has applications in agriculture and forestry. Insect net is a kind of insect net with small mesh or very small mesh made of high-density polyethylene material. Pests cannot pass through these meshes, but they can ensure the passage of sunlight and moisture. In this way, plants can be protected, and the use of pesticides can be reduced, especially for fruits, which are very healthy and environmentally friendly. The repeated use of insecticides every year will pollute the soil and ecology, poison the fruit trees, especially the enrichment effect, which will cause the quality of the fruit to decline. Therefore, most soft-skinned fruits use insect nets as the best way to prevent insects.
Insect-proof net in the forest and fruit industry.
- The anti-insect effect of the anti-insect net
Covered during the whole growth period of fruit trees, no adult pests can fly in. Fruit trees cultivated in summer can basically avoid various pests such as Pieris rapae, Plutella xylostella, Brassica oleracea, Spodoptera litura, Yellow beetle, apes, aphids, etc. Harm.
- Disease prevention function of insect-proof net
The disease prevention effect of the fruit tree insect screen is mainly reflected in effectively inhibiting the invasion of pests, while cutting off the transmission route of the virus, reducing the occurrence and harm of virus-transmitting insects, and the ventilation of the insect screen is good, and it also inhibits some bacteria to a certain extent. Sexual and fungal diseases occur.
- Insect net’s shading and cooling effect
Excessive sunlight will have a negative effect on fruit trees, speed up metabolism, and accelerate decline. After the insect screen is covered, it can block part of the light, so that the crop can get the light needed for photosynthesis. Generally, the shading rate of the white insect net is 15%-20%, and the white insect net has the function of scattering the light when the light passes through, making the light in the net more uniform, and reducing the insufficient light of the lower leaves caused by the blocking of the upper branches and leaves of the fruit tree. This phenomenon improves the utilization rate of light.
- The anti-disaster effect of the insect-proof net
Fruit tree insect-proof nets are made of high mechanical strength. Heavy rain or hail falls on the nets, and then enters the nets after impact. The impulse is buffered, thereby effectively reducing the impact of heavy rains, storms and other disasters on crops. At the same time, the insect-proof net also has a certain anti-freezing effect.
- Insect nets save labor and save money
Although the shading effect of using sunshade nets in production is good, it is not suitable to cover the whole process because of too much shading. It needs to be covered at noon after the shading is lifted or covered during the day and night, or covered under the sun, and the management is more labor-intensive. Insect nets provide less shading and can cover the whole process. Once used to the end, management will save labor. After applying the insect-proof net, the fruit trees can be completely free of insecticides during the whole growth period, which can control the pollution of insecticides and save the labor of pesticides and spraying.
