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

The antifreeze Pesticidal technology of one planting fruit-trees

Technical field

The invention belongs to the fruit tree planting technique field, relate to the antifreeze Pesticidal technology of a planting fruit-trees.

Background technology

The production of fruit trees overwhelming majority is still outdoor cropping.And outdoor cropping is subjected to the impact of natural cause larger, and freeze injury is exactly a key factor that affects production of fruit trees, and the lighter endures cold the tree body, and branch, bud are drained, and cause the death of tree body and total crop failure when serious.Freezing injury of fruit trees and seeds, the age of tree, tree upper part, physical features, management etc. have substantial connection.Show as: 1, different tree species freeze injury degree is different.Chinese prickly ash, apricot, Chinese chestnut, jujube etc. since fallen leaves early, the cortex water content is low, is difficult for being subjected to freeze injury, and walnut, peach, apple, grape etc. are owing to growing prosperous in fallen leaves evenings, the cortex water content is high, easily endures cold.2, the different age of tree freeze injury of same seeds degree is different.The freeze injury of young-abounding tree is more serious than the strong tree of large tree.3, the different parts degree difference of enduring cold.The position that water content is high is serious, and the windward side is serious; Ripe branch is more freeze proof, and bud is easily endured cold, and the branch place endures cold seriously owing to easily accumulated snow is icing.4, the different physical features degree difference of enduring cold.The place of high-land, arid, freezing injury of fruit trees is slightly light, and the local freeze injury of hypsography low-lying, impeded drainage is serious.5, meticulous, the increasing application phosphorus potassium fertilizer of management, later stage control water, in time fallen leaves, tree freezing tolerance that branch is sturdy are strong; Extensive management, partially water many, the branch excessive growth, unsubstantial tree freezing tolerance of nitrogen fertilizer application, later stage is poor.

Summary of the invention

The present invention is intended to solve the problem of fruit tree freezing tolerance and pest-resistant harmful ability, prevents from setting body and endures cold, and branch, bud are drained.The freeze injury problem that can solve low temperature, damage to plants caused by sudden drop in temperature, ice and snow, freeze injury, early frost, Cold Dew wind, " cold in the late spring " causes.

The present invention is achieved through the following technical solutions:

The antifreeze Pesticidal technology of one planting fruit-trees, by the end of September or at the beginning of 10 months, basal dressing early, organic fertilizer; In time spray Handilong, amino acid or a rare earth after the fruit picking, antifreeze drought resisting has additional nutrients, and prevents stripping, promote bud satiation, the tree body is healthy and strong, can't carry out the fruit tree of spray leaf fertilizer to falling leaves, and can smear amino acid one time at trunk, commute freezes fruit tree can spray antifreezing agent one time behind fallen leaves, or tree dish base portion earthed up, prevent that root system from enduring cold, can also be coated with one deck limewash to butt and major branch.Enter resting stage, the resistance of germ weakens and the resistance of fruit tree begins to strengthen, and sprays the high concentration agricultural chemical that can not use vegetative period before fruit tree germinates; When reduces heat, in time take trunk to tie up the safeguard procedures such as grass handle, plastic material film, the ridging of tree dish, after the sleet, in time the accumulated snow on the cleaning tree prevents from freezing, after the generation freeze injury, spray early rot fast health and brown sugar mixed liquor, prune in conjunction with the situation of enduring cold the beginning of spring, and light pruning length is put, and in time sprays lime sulfur.

Compared with prior art, the present invention has following useful technique effect:

The present invention not only can prevent the freeze injury of fruit tree, and can repair light cold damage damaged cell, makes to be subjected to that light cold damage cell is most of replys.Can strengthen the cold-resistant insect resistance capacity of preserving moisture of fruit tree, alleviate freeze injury harm, improve anti-adversity ability, reduce freezing point, mild or moderate freeze injury plant is had alleviate, rehabilitative action.Improve the fruit tree percentage of fertile fruit, improve fruit tree high yield the effect of increasing income.Embodiment

Claims

1. the antifreeze Pesticidal technology of a planting fruit-trees is characterized in that: by the end of September or at the beginning of 10 months, and basal dressing early, organic fertilizer; In time spray Handilong, amino acid or a rare earth after the fruit picking, antifreeze drought resisting has additional nutrients, and prevents stripping, promote bud satiation, the tree body is healthy and strong, can't carry out the fruit tree of spray leaf fertilizer to falling leaves, and can smear amino acid one time at trunk, commute freezes fruit tree can spray antifreezing agent one time behind fallen leaves, or tree dish base portion earthed up, prevent that root system from enduring cold, can also be coated with one deck limewash to butt and major branch; Enter resting stage, the resistance of germ weakens and the resistance of fruit tree begins to strengthen, and sprays the high concentration agricultural chemical that can not use vegetative period before fruit tree germinates; When reduces heat, in time take trunk to tie up the safeguard procedures such as grass handle, plastic material film, the ridging of tree dish, after the sleet, in time the accumulated snow on the cleaning tree prevents from freezing, after the generation freeze injury, spray early rot fast health and brown sugar mixed liquor, prune in conjunction with the situation of enduring cold the beginning of spring, and light pruning length is put, and in time sprays lime sulfur.
