Not only does it have the characteristics of bird resistance, but it also has the characteristics of insect resistance. It mainly uses polyethylene or steel wire rope with anti-aging, UV resistance and other chemical additives as the main raw material, and is made of mesh fabric through wire drawing. It has the advantages of high tensile strength, heat resistance, water resistance, corrosion resistance, aging resistance, non-toxic and odorless, and easy to dispose of waste.

The relevant knowledge of polyethylene bird prevention nets is detailed as follows:

1. Insect prevention After covering up the insect prevention net to prevent viral diseases, it can basically eliminate the harm of various pests such as cabbage beetle, diamondback moth, cabbage armyworm, striped armyworm, yellow flea beetle, ape leaf beetle, aphid, etc., and control the outbreak of viral diseases caused by the spread of pests.

2. The experiment of adjusting temperature and ground temperature showed that under a 25 mesh white insect prevention net, the temperature of the greenhouse was at the same level as that of the open field in the morning and evening, while on a sunny day at noon under high temperature conditions, the temperature inside the net was about 1 ℃ higher than that of the open field; The temperature of the 10cm surface in the greenhouse is higher than that in the open field in the morning and evening, and lower than that in the open field at noon. According to observation, from late March to early April in early spring, the temperature inside the insect net covered greenhouse is 1-2 ℃ higher than that of the open ground, and the 5cm ground temperature is 0.5-1 ℃ higher than that of the open ground, which can effectively prevent frost.

3. Generally speaking, the shading rate of 25 mesh white insect net is 15% -20%, which is lower than that of agricultural film and shading net. After covering up the insect net, the relative humidity of the air inside the net is about 5% higher than that in the open air, and it is about 10% higher after watering, which has a certain moisturizing effect.
