Kiwi fruit winter frost damage prevention method

Abstract

The invention discloses a kiwi fruit winter frost damage prevention method. The method includes the steps that foliage fertilizer is applied in October to November at the late growth stage of kiwi fruits, and monopotassium phosphate or phytoalexin or fertility micro element fertilizer is sprayed; after winter comes, more fertilizer is applied, pits at kiwi fruit trunks close to roots are expanded, and rotten manure or pig and cattle pen manure or organic biological fertilizer is applied; the kiwi fruit trunks close to the roots are covered, the kiwi fruit trunks close to the roots are covered with rice straw, straw and weeds in winter, or the kiwi fruit trunks close to the roots are covered with a mulching film; before frost approaches, the mulching film or straw mats cover branches of a kiwi fruit shed frame. The kiwi fruit winter frost damage prevention method has the advantages that tree vigor can be improved through fertilization application, and the stress resistance of the kiwi fruits is improved; the soil temperature can be raised by covering the kiwi fruit trunks close to the roots, so that root systems are protected; by covering the branches of the kiwi fruit shed frame, water loss and cracking of the branches can be prevented. It has been proved that the kiwi fruits can be protected to survive the winter safely.

Description

technical field [0001] The invention relates to the cultivation of kiwifruit, in particular to a method for preventing kiwifruit from freezing damage in winter. Background technique [0002] During the growing season and dormant season, kiwifruit often encounters long-term low temperatures of -8°C-1.5°C, and even short-term low temperatures of -10°C. Low temperature and freezing will cause branches to lose water, branches to split, and even die , causing losses in production. At present, the method of fumigation is commonly used to prevent freezing, but the cost is high and the effect is not good. Contents of the invention [0003] The purpose of the invention is to provide a method for preventing kiwi fruit from freezing damage in winter. [0004] The technical scheme that realizes the object of the present invention is: [0005] A method for preventing kiwi fruit from freezing damage in winter, comprising the following technical measures: [0006] 1. Apply foliar fer...
