Covering insect nets can prevent frost.
The young and mature stages of fruit trees are in the low-temperature season, which can easily cause cold or freezing damage. The use of insect proof nets for coverage not only helps to improve the temperature and humidity inside the nets, but also uses the isolation of insect proof nets to prevent frost damage on the fruit surface, which has a very significant effect on preventing frost damage during the young fruit stage of loquat and cold damage during the mature fruit stage of citrus.
