Abstract

The invention discloses a method for prevention and treatment of blossom and fruit drop of apple trees. The method comprises the following steps: applying base fertilizer before and after fruit picking to apple trees, wherein the base fertilizer is formed by mixing organic fertilizer with chemical fertilizer according to the mass ratio of 10:(1-2); performing artificial supplementary pollination or insect supplementary pollination during the flower reason of apples, spraying 0.3wt%-0.5wt% of borax during the flower reason, and spraying the mixture formed by 0.3wt%-0.5wt% of borax, 0.2wt%-0.3wt% of dipotassium phosphate and 0.3wt%-0.5wt% of urea after flowering; performing girdling, pinching, shoot twisting and branch bending on tree bodies from mid-May to mid-June. According to the method, phenomena of blossom drop and fruit drop of apple trees are effectively controlled, fruit yield is increased, benefits are increased, and the tree bodies are kept healthy and strong. The method is simple and convenient, low in cost, and suitable for large-area application.

Description

A kind of method of preventing and treating apple tree fruit drop

Technical field

The present invention relates to fruit tree planting technique field, be specifically related to a kind of method of preventing and treating apple tree fruit drop.

Background technology

Apple belongs to the rose family, and in 4～June of florescence, fruit fruit in 7～November of phase is ripe.Fruit is spherical, and taste is sweet, is common fruit, is also modal fruit, is rich in abundant nutrition, is the hat of the large fruit in the world four (apple, grape, citrus and banana).

Most apple trees all bloom every year in a large number, but only have 2%～20% spend and finally grow into fruit.All the other more than 80% flowers, after spending, (in earlier stage) or young fruit development phase (later stage) come off successively.Too much fruit drop, not only affects output, benefit, also can weaken the tree vigo(u)r of fruit tree itself.In earlier stage the main cause of fruit drop, be the bad or not fertilization of being fertilized, or embryonic development is bad; The main cause of later stage shedding is that the nutriment of preserving on tree body lacks fruit undersupply or nourish and grow or damage by disease and insect harm out of proportion with reproductive growth etc.In production, how preventing too much fruit drop, not only can improve output, increase benefit, is also the requisite measure of high-quality, stable yields and maintenance tree body stalwartness.

Summary of the invention

The object of the invention is to provide a kind of method of preventing and treating apple tree fruit drop, solves the too much fruit drop of apple, to improve output, to increase benefit, keeps tree body healthy and strong.

The present invention is by the following technical solutions:

A method of preventing and treating apple tree fruit drop, comprises the steps:

Step 1, before and after the apple tree fruit picking basal dressing, described base manure is that fertilizer and chemical fertilizer mix 10:1～2 in mass ratio;

Step 2, in Blooming Date of Apple Trees, carry out artificial supplementary pollination or insect supplementary pollination, and at the borax of florescence spray 0.3wt%～0.5wt%, spend the urea of borax+0.2wt%～0.3wt% dipotassium hydrogen phosphate+0.3wt%～0.5wt% of rear spray 0.3wt%～0.5wt%;

Step 3, mid-May to mid-June to tree body carry out band girdle, pinching, turn round slightly and smooth out with the fingers branch.

Described in step 1, basal dressing is to apply fertilizer by 40%～50% of fruit quality.

Described in step 2, insect supplementary pollination is honeybee supplementary pollination or wall honeybee supplementary pollination.

Described in step 3, band girdle is no more than 10% of branch thick.

Beneficial effect of the present invention:

1, the inventive method is effectively controlled apple tree fruit drop, has improved fruit yield, has increased benefit, and kept tree body healthy and strong.

2, the inventive method is simple, convenient, and cost is low, can be applicable to large area and use.

Embodiment

Below in conjunction with embodiment, the present invention is done further and explained.Following embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all among protection scope of the present invention.

A method of preventing and treating apple tree fruit drop, comprises the steps:

Step 1, press 40%～50% basal dressing of fruit quality before and after the apple tree fruit picking, described base manure is fertilizer and chemical fertilizer 10:1～2 mixing in mass ratio;

Step 2, in Blooming Date of Apple Trees, carry out artificial supplementary pollination or honeybee supplementary pollination or wall honeybee supplementary pollination, and at the borax of florescence spray 0.3wt%～0.5wt%, spend the urea of borax+0.2wt%～0.3wt% dipotassium hydrogen phosphate+0.3wt%～0.5wt% of rear spray 0.3wt%～0.5wt%;

Step 3, mid-May to mid-June to tree body carry out band girdle, pinching, turn round slightly and smooth out with the fingers branch, wherein, band girdle is no more than 10% of branch thick.

Embodiment 1

1, before apple tree fruit picking, press 40% basal dressing of fruit quality, described base manure is fertilizer and chemical fertilizer 10:1 mixing in mass ratio;

2, in Blooming Date of Apple Trees, carry out artificial supplementary pollination, and at the florescence, spray the borax of 0.3wt%, spend borax+0.2wt% dipotassium hydrogen phosphate+0.3wt% urea of rear spray 0.3wt%;

3, mid-May, tree body is carried out band girdle, pinching, turns round slightly and smooth out with the fingers branch, wherein, band girdle is no more than 10% of branch thick.

Embodiment 2

1, after apple tree fruit picking, press 50% basal dressing of fruit quality, described base manure is fertilizer and chemical fertilizer 10:2 mixing in mass ratio;
