Method for preventing fruit tree frostbite

Abstract

The invention discloses a method for preventing fruit tree frostbite. The method comprises the following steps that (1) main branches and new branches on mother branches of fruit tree are pruned in autumn so that the length of the main branches to be larger than the length of the new branches, and the pruned main branches and new branches are arranged in a staggered way, are pulled to a horizontalstate, and are fixed by iron wires; (2) the end parts of the pruned main branches and new branches are coated with plastic films, and the upper parts of the pruned main branches and new branches arecovered with dry straw, and the fixing is carried out by using an iron wire; (3) a groove is dug at a place which is 1.0-1.5m out of a main root of the fruit tree, and fertilizer is laid in the groove; (4) winter irrigation is carried out on the fruit tree in winter, and the grooves are filled with grove digging soil, so that the groove is flushed with the ground; and (5) a whitening agent is smeared on a tree trunk of the fruit tree in winter, and an anti-freezing agent is sprayed on the fruit tree branches. The anti-freezing measures provided by the invention are comprehensive and reasonable, and effective anti-freezing is carried out on the fruit tree.

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...

Problems solved by technology

[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 prevent fruit trees from freezing

[0004] In summary, the antifreeze measures for fruit trees in the prior art have the problem that the antifreeze measures are simple and cannot effectively prevent the fruit trees from freezing.
