Problems solved by technology

[0003] The invention aims to solve the problem of poor antifreeze ability and insect resistance ability of fruit trees, prevent the tree from being frozen, and dry out branches and buds
It can solve the problem of freezing damage caused by low temperature, freezing damage, ice and snow, freezing damage, early frost, cold dew wind, and "late spring cold"

specific Embodiment approach

[0008] An antifreeze and anti-insect technology for fruit trees. At the end of September or early October, early application of base fertilizer and organic fertilizer; timely spraying of dry land dragon, amino acid or rare earth once after fruit picking, antifreeze and drought resistance, increase nutrition, prevent stripping, and promote full flower buds. The tree body is strong. For fruit trees that have lost leaves and cannot be sprayed on the leaves, amino acids can be applied to the trunk once. For fruit trees that are prone to freezing, antifreeze can be sprayed once after falling leaves, or the base of the tree can be soiled to prevent the roots from being frozen. You can apply a layer of lime water to the trunk base and main branches. Entering the dormant period, the resistance of the bacteria weakens and the resistance of the fruit trees begins to increase. Before the fruit trees germinate, spray high-concentration pesticides that cannot be applied during the growth pe...

Abstract

The invention discloses an anti-freezing and insect-preventing technology of fruit trees. The anti-freezing and insect-preventing technology comprises the following steps of: applying a base fertilizer as soon as possible and then applying an organic fertilizer in the end of September or the beginning of October; spraying a fulvic acid drought resistance agent, amino acids or rare earth on the fruit trees once in time after fruit picking, wherein with regard to leaf-fallen fruit trees which cannot be subjected to foliage application, the amino acids can be sprayed onto trunks once, an antifreezing agent can be sprayed onto leaf-fallen easy-to-freeze fruit trees once, or the roots of the leaf-fallen easy-to-freeze fruit trees are earthed up to prevent root systems from being frozen, and the truck base parts or main branches can be also coated with a layer of whitewash; after the fruit trees enter a dormancy peroid, spraying a high-concentration pesticide before the fruit trees are germinated, wherein the high-concentration pesticide cannot be applied in the growth peroid; and when temperature drop sharply happens, taking protective measures of binding grass bundles on trunks, wrapping plastic films, earthing up the tree roots and the like in time, cleaning accumulated snow on the trees after snow and rain so as to prevent icing, spraying a Fulan Sukang and brown sugar mixed solution as soon as possible after freeze injury happens, and spraying lime sulphur in time in the beginning of spring. The anti-freezing and insect-preventing technology disclosed by the invention has the advantages of enhancing the water-retention, anti-freezing and insect-preventing capabilities of the fruit trees, increasing the fertile fruit rate of the fruit trees and improving the high-yield effect of the fruit trees.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and relates to an antifreeze and insect-proof technology for fruit trees. Background technique [0002] The vast majority of fruit tree production is still cultivated in the open field. The open field cultivation is greatly affected by natural factors, and freezing damage is an important factor affecting the production of fruit trees. The light ones cause the tree body to be frozen, and the branches and buds are drained. Freeze damage to fruit trees is closely related to tree species, tree age, tree parts, topography, and management. The performances are as follows: 1. Different tree species have different degrees of frost damage. Zanthoxylum bungeanum, apricot, chestnut, jujube, etc. are less susceptible to freezing damage due to early leaf fall and low cortex water content, while walnuts, peaches, apples, grapes, etc. are late leaf fall, vigorous growth, high cortex water cont...
