Effect of late spring cold on fruit trees

1, "late spring cold" is very harmful to fruit trees. When the "late spring cold" occurs, the fruit trees will be frozen. At this time, if the fruit tree is in its infancy, the buds will be damaged and the leaves of the fruit tree will be irregular and small! If the fruit tree is in flowering or young fruit stage, freezing injury will cause flowers or fruits to fall off, which will seriously affect the fruit tree yield! And the cold in late spring will aggravate some diseases. After the cold in late spring, the barks of peach trees and plum trees will be damaged, and the gum will easily flow behind them, which will destroy the nutritional components of fruit trees, leading to the loss of nutritional components of fruit trees, weak growth of fruit trees and less fruit food.

2. "Late spring cold" refers to the phenomenon that the temperature rises rapidly in early spring (late February and early March), but the temperature in late spring cold (April) is lower than usual. The main reason is that in early spring and late spring, due to the influence of cold air flow, the temperature plummeted, resulting in "late spring cold".
