Abstract

The invention relates to a method for preventing a fruit free from being frostbitten. The method for preventing the fruit free from being frostbitten comprises the steps of (1) applying base fertilizer in early stage, wherein organic fertilizer or inorganic fertilizer is applied in the end of September or at the beginning of October; (3) conducting whitening on the trunk, wherein 9 parts to 11 parts of quicklime, 1 part to 3 parts of sulphur powder, 1 part to 3 parts of salt, 0.1 part to 1.6 parts of plant oil and 20 parts to 27 parts of clear water are evenly mixed, and then the mixture is painted to the trunk and bifurcations of skeleton branches; (3) covering the root of the tree with a mulching film and straw, wherein before the First Frost, the entangle root of the tree is covered with the mulching film with the length ranging from 0.5 m to 1.2 m, and then the mulching film is covered with the straw with the thickness ranging from 15 cm to 20 cm; (4) removing snow accumulated on the body of the tree, wherein after a snow, snow accumulated on the tree should be shaken down in time, and the snow is accumulated on the root of the tree. According to the method for preventing the fruit free from being frostbitten, the fruit tree can be prevented from being frostbitten, slightly frostbitten cells can be renovated, and most of the slightly frostbitten cells can be recovered; the water retention capacity and the cold resistance of the fruit tree can be improved, cold damage is reduced, the cultivation of resilience is improved, the freezing point is lowered, damage of moderately and slightly frostbitten plants can be relieved, and the moderately and slightly frostbitten plants can be recovered; the percentage of fertile fruits of the fruit tree is increased, the yield of the fruit free is increased, and the income is increased; meanwhile, the method is simple, popular and easy to understand, and time, labor and money are saved.

Description

A kind of method of freezing protection for fruit tree

Technical field

The present invention relates to plant maintenance method, particularly a kind of method of freezing protection for fruit tree.

Background technology

The production of fruit trees overwhelming majority is still outdoor cropping.And outdoor cropping is comparatively large by the impact of natural cause, freeze injury is exactly the key factor affecting production of fruit trees, and the lighter makes tree body endure cold, and branch, bud are drained, and causes the death of tree body and total crop failure time serious.On freezing injury of fruit trees and seeds, the age of tree, tree, position, 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. are owing to falling leaves early, and cortex water content is low, and not easily by freeze injury, and walnut, peach, apple, grape etc. are owing to falling leaves evening, and grow prosperous, cortex water content is high, easily endures cold.2, same seeds different age of tree freeze injury degree is different.The freeze injury of young-abounding tree is more serious than the strong tree of large tree.3, different parts is endured cold degree difference.The position that water content is high is serious, and windward side is serious; Ripe branch is more freeze proof, and bud is easily endured cold, and branch place endures cold serious because easy accumulated snow freezes.

Frostbite brings serious economic loss to orchard worker every year, existing means to prevent freezing complicated operation and wasting time and energy, and effect is not clearly.

Summary of the invention

For solving the deficiency of existing fruit tree maintenance process, the object of the present invention is to provide a kind of simple, saving time, saving of labor, to save money and the method for effective anti-fruit tree frostbite.

For achieving the above object, the present invention is achieved by the following technical solutions, and concrete steps are as follows:

(1) early basal dressing, organic fertilizer material or inorganic fertilizer at the beginning of by the end of September or 10 months;

(2) trunk is whitewashed, and by quicklime 9 ~ 11 parts, Cosan 1 ~ 3 part, salt 1 ~ 3 part, vegetable oil 0.1 ~ 1.6 part, 20 ~ 27 parts, clear water are mixed even rear brushing at trunk and skeleton branch crotch;

(3) covering with plastic film, lid grass: in the mulch film that tree dish covering 0.5 ~ 1.2 meter is square before the Frost's Descent, then add a cover the grass of 15 ~ 20 centimetres on mulch film;

(4) remove tree volume snow: after snowing, the accumulated snow trembled on tree should be shaken in time, and accumulated snow heap is trained the root in tree.

Further, organic manure described in step (1) selects stalk, people and animals' fecaluria; Described inorganic fertilizer is nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, micro-fertilizer mix according to 3:2:2:1.

Further, trunk described in step (2) is whitewashed and is carried out in late October.

The invention has the beneficial effects as follows: a kind of method that the invention provides freezing protection for fruit tree, the method not only can be antifreeze, and can repair light cold damage damaged cell, makes to reply by light cold damage cell major part.Preserving moisture of fruit tree cold tolerance can be strengthened, alleviate freeze injury harm, improve anti-adversity ability, reduce freezing point, have mild or moderate freeze injury plant alleviate, rehabilitative action.Improve fruit tree percentage of fertile fruit, improve fruit tree and to get bumper crops the effect of increasing income, and method is simple, easy-to-understand, and save time, saving of labor, to save money.

Embodiment

For understanding the present invention better; below by embodiment, elaboration concrete is further done to the present invention; but unintelligible is limitation of the invention; for some nonessential improvement and adjustment that those skilled in the art does according to foregoing invention content, be also considered as dropping in protection scope of the present invention.

embodiment 1

The method of a kind of freezing protection for fruit tree of the present embodiment, concrete steps are as follows:
