The main function of fruit tree insect control net coverage:
1. After the orchards and nurseries are covered with insect-proof nets, the prevention and control of these pests can be achieved by blocking the occurrence and transmission of various fruit pests such as aphids, psyllids, fruit-sucking moths, fruit flies, etc. It can control the damage of aphids, psyllids and other vector insects, and play an important role in preventing and controlling the spread of citrus yellow dragon disease, decay disease and other diseases, as well as the control of bayberry (blueberry) fruit flies. In order to ensure the safe production of fruit virus-free seedlings.
2. Anti-frost Fruit trees are in freezing and early spring low temperature seasons at the young fruit stage and fruit maturity stage, and are susceptible to frost damage, resulting in cold damage or freezing damage. The use of insect-proof net covering is not only conducive to improving the temperature and humidity in the net, but also uses the isolation of the insect-proof net to prevent frost damage on the fruit surface, which has a very obvious effect on preventing frost damage at the young fruit stage of loquat and chilling damage at the mature fruit stage.
3. Anti-dropping bayberry fruit ripening period coincides with heavy rainy weather in summer. If the insect-proof net is used to cover, it will reduce the fruit drop caused by rainstorm during the ripening period of bayberry, especially in years with heavy rain during the ripening period of bayberry fruit. obvious.
4. The slow-ripening fruit trees are covered with insect-proof nets, which can block light and prevent direct sunlight. Generally, the ripening period of fruit trees will be delayed by more than 3 to 5 days. For example, net cultivation of bayberry will delay the ripening period of fruit by about 3 days compared with open field cultivation. Net cultivation, the fruit ripening period should be delayed for more than 5-7 days.
5. Anti-bird damage Fruit trees are covered with insect-proof nets, which not only facilitates high yields and harvests, but also prevents birds from pecking, especially cherries, blueberries, grapes and other fruits that are susceptible to bird damage, which are ideal for bird damage prevention.
