The cold wave hits the orchard to prevent freezing
â— Fruit trees are protected from freezing and cold, and they must be “eat and wear wellâ€
â—The fruit tree is painted white to prevent disease
â— After the freezing damage occurs, the fruit tree is remedy
Recently, due to the influence of strong cold air, the temperature in most parts of central and eastern China has dropped by 6 °C ~ 8 °C, and there will be rain and snow in many places. Under the influence of this cold current, fruit tree growth will be seriously affected. When the temperature is too low, the water in the fruit trees is frozen in the interstitial space, causing physiological damage to the plant tissue. After the frostbite of the tree, it is easily infected by the pathogen, and then the germ spreads, which damages other healthy cells and parts, causing secondary harm and inducing disease. Therefore, winter orchard antifreeze measures are the focus of management. Management should take measures such as supplementing nutrition and preventing pests and diseases to enhance resistance, and adopt measures such as tree binding, fumigation, whitening, and antifreeze to prevent freezing damage. After the occurrence of freezing damage, it should be remedied by pruning, nourishing, spraying, etc., and finally achieve the purpose of safe wintering of the fruit trees.
