Abstract

The invention discloses a sweetness reinforcement method of loquat fruit. The sweetness reinforcement method of the loquat fruit aims at resolving the problem that at present fruit tree sweetener used in production is difficult to overcome sour of the loquat fruit, and is a cultivation and management method capable of improving the sweetness, quality and output of the fruit. The sweetness reinforcement method of the loquat fruit is characterized in that 0.5% of monopotassium phosphate is sprayed on leaves in a full-blossom period of a loquat garden, 0.05% of borax is added, and then peanut bran liquid fertilizer is added; and in a young fruit period, fruit thinning is carried out, 0.5% of the monopotassium phosphate is sprayed for the second time, and the peanut bran liquid fertilizer is added. By means of the sweetness reinforcement method of the loquat fruit, the yield per unit area of the loquat fruit is improved by 25%, and the sweetness of the fruit can reach 11-13% (soluble solid).

Description

A kind of sweetening method of loquat

Technical field

The invention belongs to the fruit tree planting technique field, particularly a kind of loquat increases sweet method.

Background technology

Loquat is the south China famous and high-quality fruit.During fruit maturation, tart flavour is heavier, and the market price reduces.Produce at present the upper fruit tree sweetener that uses, even increase usage amount, increase sweet effect also not obvious, be difficult to overcome the problem of loquat tart flavour.

Summary of the invention

The objective of the invention is for using the fruit tree sweetener in present production, loquat increases sweet DeGrain, is difficult to overcome the problem of loquat tart flavour, provide a kind of cost low, simple and easy to do, and can improve the cultivation management method of fruit sweetness, quality and yield

The main points of the technical solution used in the present invention are: the potassium dihydrogen phosphate at Loquat Garden full-bloom stage foliage-spray 0.5% adds 0.05% borax, then adds the peanut press pulp liquid fertilizer; Young fruit period carries out fruit thinning, sprays the potassium dihydrogen phosphate of secondary 0.5%, adds the peanut press pulp liquid fertilizer.

Method of operating of the present invention is:

1, soil increases and puts farmyard manure.Soil application will be according to distribution, growth and the soil condition etc. of loquat root system, takes the method for digging the strip ditch around the tree crown drip, puts into various fertilizer, is beneficial to the fruit tree Root Absorption.Annual 3-4 time of soil application.Should be noted increasing application phosphorus potassium fertilizer, as yielding positive results then excessively, should be noted to enrich nitrogenous fertilizer, recover to promote tree vigo(u)r.After annual fruit picking, the 5--6 month is compounding applications such as fertilizer, cake fertilizer, compost etc. and instant nitrogenousfertilizer phosphate fertilizer.Farmers' big porker, cow dung barnyard manure 20-40 kilogram are executed in strain, 1 kilogram, fused calcium magnesium phosphate, and fruit tree Chemical Mixed Fertilizer 1-2 kilogram, 1 kilogram of peanut press pulp, fertilizer and soil are wanted abundant mixing.

2, foliar applied fertilizer.Pore on the loquat blade face and cuticula can rapidly, directly absorb various nutrients.Need not pass through root system owing to absorbing fertilizer, and do not set the impact of nutrient distributing center in body, therefore can satisfy in time the needs that the loquat flowers and fruits are grown.

(1) preparation of peanut press pulp liquid fertilizer: the peanut press pulp powder is put into water, and the ratio of peanut press pulp and water is 1: 15, allows it decompose under anaerobic environment.Use after 2 months, the ripe rotten time is not over 4 months.During use, need the mother liquor thin up.

(2) the florescence spray is fertile.At loquat orchard full-bloom stage, namely the orchard has the plant more than 90% all to bloom, and in 3--4 days thereafter, sprays 0.5% potassium dihydrogen phosphate with sprayer, adds 0.05% borax, adds peanut press pulp liquid fertilizer (ratio of mother liquor and water is 1: 10).Spray the time, select fine day morning, spray in rear 2 hours as rainwater, need again spray.

(3) the young fruit period spray is fertile.Spray the potassium dihydrogen phosphate of 2 times 0.5% at the loquat young fruit period, add peanut press pulp liquid fertilizer (ratio of mother liquor and water is 1: 10), every minor tick 8-10 days.Liquid fertilizer wants even spraying on blade face and fruit face.Spray the time, select the morning of fine day.

3, flower thinning fringe, bud, young fruit.

(1) flower thinning fringe.Between the month, every young fringe on tree crown carries out the flower thinning fringe when all having revealed at 10-11.When as too much in the loquat flower fringe, can remove the colored fringe on the long tip on the skeleton branch of tree crown top or weak branch.As on female branch, 2-3 fringe being arranged, should dredge 1 fringe, what 4--5 fringe arranged thinly removes 2 fringes.General tree crown is dredged on the top more, stays 1/3 colored fringe; Dredge less the tree crown bottom, stays 2/3 colored fringe.In addition, the inflorescence of good year tree, old tree, old and feeble tree, weak tree is dredged more, after making it pass through to dredge fringe, sprouts strong branch, the recovery tree vigo(u)r.

(2) flower thinning flower bud.The general every fringe of large fruit kind stays 2-3 fulcrum, in, the every fringe of small fruit type kind stays 3-4 fulcrum.Extract the bud of each fulcrum tip, keep the bud of fulcrum base portion.

(3) dredge young fruit.Fruit thinning is chosen in late December to early January period.The principle of fruit thinning.The every fringe of large fruit kind stays 3-4, and the every fringe of middle fruit type kind stays 4-5.During fruit thinning, first extract malformed fruit, sick wormed fruit or hypogenetic young fruit.Also to consider during fruit thinning on fruit ear the fruit position, unsuitable crowded between fruit and fruit, can not collide with branch, stay the fruit of hiding in leafage as far as possible.

Adopt this method, can make the loquat per mu yield improve 25%, fruit sweetness reaches 11-13% (soluble solid).

Claims

1. the sweetening method of a loquat, is characterized in that, the potassium dihydrogen phosphate at Loquat Garden full-bloom stage foliage-spray 0.5% adds 0.05% borax, then add the peanut press pulp liquid fertilizer; Young fruit period carries out fruit thinning, sprays the potassium dihydrogen phosphate of secondary 0.5%, adds the peanut press pulp liquid fertilizer.
