Function of Anti Insect Netting

Anti insect netting is like window screen, with high tensile strength, anti-ultraviolet, heat, water, corrosion, aging and other properties, non-toxic and tasteless, the service life is generally 4-6 years, up to 10 years. It not only has the advantages of sunshade net, but also overcomes the shortcomings of sunshade net, which is worthy of vigorous promotion.

Funtion of anti insect netting

1. Frost-proof

Fruit trees at young fruit stage and fruit ripening stage are in the freezing and early spring low temperature season, which are vulnerable to frost damage, causing chilling injury or freezing injury. The application of anti insect netting covering not only helps to increase the temperature and humidity in the net, but also prevents frost injury on fruit surface by isolation of anti insect netting. It has a very obvious effect on preventing frost injury in young loquat fruit stage and cold injury in mature citrus fruit stage.

2. Prevention of Diseases and insects

After covering orchards and nurseries with anti insect netting, the occurrence and transmission routes of fruit pests such as aphids, psylla, fruit-sucking armyworm, carnivorous insects and fruit flies are blocked, so as to achieve the purpose of controlling these pests, especially the pests of aphids, Psylla and other vectors, and to prevent and control citrus yellow dragon disease and decline disease. The spread of diseases such as pitaya fruit and blueberry fruit flies plays an important role.

3. Fruit drop prevention

Fruit ripening period is a rainstorm weather in summer. If anti insect netting is used to cover the fruit, it will reduce the fruit drop caused by rainstorm during fruit ripening period, especially in the rainy years of Pitaya fruit, blueberry and bayberry fruit ripening period, which has more obvious effect on reducing fruit drop.

4. Improving Temperature and Illumination

Covering anti insect netting can reduce light intensity, adjust soil temperature and air temperature and humidity, reduce precipitation in net room, reduce water evaporation in net room, and reduce transpiration of leaves. After covering anti insect netting, the relative humidity of air was higher than that of the control, and the humidity was the highest in rainy days, but the difference was the smallest and the increase was the lowest. With the increase of relative humidity in the net chamber, the transpiration of fruit trees like citrus leaves can be reduced. Water affects fruit quality development through precipitation and air relative humidity, which is more conducive to fruit growth and development, and fruit quality is good.
