Method of preventing cold injury of fruit tree

Abstract

The invention discloses a method of preventing cold injury of a fruit tree and relates to the field of fruit tree plantation. The method comprises steps that main branches and newly-born branches of a fruit tree mother shoot are trimmed in autumn; then the trimmed main branches and the newly-born branches are staggered and pulled to form a horizontal shape and then fixed by iron wires; a groove is dug at a distance of 1.0 to 1.5m from a main root of the fruit tree in autumn; organic fertilizer and inorganic fertilizer are placed layer by layer in the groove according to a thickness ratio of 4 to 1; the top layer organic fertilizer is covered with groove-digging soil with the thickness of 3 to 5cm; the fruit tree is irrigated in winter; the groove is filled with the groove-digging soil till being aligned to the land; mixtures of straws, dry faeces and oil residues are placed in 1.0 to 1.5 parts of the main root of the fruit tree layers by layers; and the rest groove-digging soil is placed on the top layer straws. The main and newly-born branches are staggered and fixed; organic and inorganic fertilizers are placed in the groove surrounding the fruit tree layers by layers, the fruit tree is irrigated in winter and mixtures of straws, dry faeces and oil residues are placed on the land surrounding the fruit tree layers by layers, so anti-frozen measurement is comprehensive and rational, and cold injury of the fruit tree can be effectively prevented.

Description

technical field [0001] The invention relates to the field of fruit tree planting, in particular to a method for preventing frostbite of fruit trees. Background technique [0002] Many fruit trees in northern my country (such as: apple trees, pear trees, peach trees, apricot trees, jujube trees, etc.) are not resistant to severe cold, and are severely frostbited every year, which affects the amount of fruit in the coming year and reduces the yield and quality of fruit trees. Freeze damage to fruit trees is closely related to tree species, tree age, tree parts, topography, and management. [0003] Existing antifreeze measures for fruit trees mainly cover or wrap branches with straw and plastic film to prevent branches from being frozen. Usually, antifreeze measures are taken for branches of fruit trees, and some simple hay mulches are carried out for the roots of fruit trees or no antifreeze measures are taken. , but these simple antifreeze measures cannot effectively antifre...
