Description

A kind of rock sugar tangerine is downgraded the implantation methods of high yield

Technical field

The invention belongs to the fruit tree planting technique field, relate in particular to the implantation methods that a kind of rock sugar tangerine is downgraded high yield

Background technology

The granulated sugar tangerine is the famous-brand and high-quality kind of citrus, its wide adaptability, and strong stress resistance, high and stable yield, fruit quality is good, and the fruit look orange is, fresh and sweet, skin is thin easily peels off, and on market, popularity is high, liked by consumers in general.Producing at present the upper subject matter existed is, because these seeds enter operation period and set body higher, to management, brings many difficulties, increases production cost, orchard up-front investment DeGrain.

Summary of the invention

The present invention is directed in the production of rock sugar tangerine and exist the tree body higher, to management, bring difficulty, increase production cost, the problem of orchard up-front investment DeGrain.A kind of implantation methods of downgrading high yield is provided.

Performing step of the present invention is as follows:

1, field is selected.Rock sugar tangerine orcharding should select that soil structure is good, soil layer is deep, fertile, irrigation and drainage convenient, sandy loam or the stony soil earth of soil acidity or alkalinity between 5.5--6.5 is advisable.

2, seedling planting.

(1) generally after young sprout is aging on once young sprout before sprouting, all can plant, take spring planting and autumn and winter to plant as good.The plantation specification adopts the Cultivation With Dwarf Varieties And Close Spacing mode, and strain, line-spacing are 2.2 * 2.5 meters, and mu is planted 120 strains.

(2) will hold plant hole successfully before the plantation, improvement plant hole soil, in order to growing of root system.Paddy field will line up high furrow by plant.The nonirrigated farmland that soil property is barren, hillside, dig dark, wide each kind plant hole of 1 meter or adopt trench to replace plant hole, presses one deck soil one deck nutriment in a fertilizer 3-4 layer during earth backing, and general every cubic metre of plant hole should be put sufficient 75-100 kilogram farmyard manure, 0.5-0.75 kilogram lime.

3, earsh management.

(1) target of earsh management: cultivate into underground root system powerful, overground part skeleton branch is strong, the structure steady.Early knot, high yield, stable yields knob type tree crown.

(2) the earsh tree crown is little, and between strain, line-spacing, vacant lot is many, should take full advantage of between carrying out and plant, cultivating peanut, the short stalk crops such as beans, green manure are for well, in order to increase soil fertility and improve orchard microclimate.

(3) put in time the tip.It is main that one age set to cultivate tree crown, puts the tip well four times, and each tip requires that the healthy and strong young sprout of 2--3 treaty 6-8 cun is arranged on each base tip.1. the spring tip (February), 2. summer shoot (the first tenday period of a month in May) early, 3. slow summer shoot (on July, the middle ten days), 4. autumn growth (mid-September), the autumn growth of the tree that bears fruit the coming year is put during the tip time should be selected in the Limit of Heat to White Dew, will be carried out the work of bud picking control shoot while putting the tip, two 80% of emphasis GPRSs just can be put the tip, there is 80% full the sprouting of tree eye in the Ji Quan garden, and every strain has 80% branch to sprout to take out to tell.

4, bearing-age tree management.

(1) fertilising.Executed fertilizer four times.1. urge the flower tip-promoting fertilizer.Under executing, take available N fertilizer as main before the spring tip.2. fruit retention fruit-promoting fertilizer.Under mainly executing, should be cautious use of N fertilizer, in conjunction with P, K fertilizer before physiological fallen fruit for the second time.3. autumn growth fertilizer.Under within 15-20 days before White Dew, executing, take available N fertilizer as main, coordinate P, K fertilizer.4. winter top dressing.Under executing after fruit picking, take complete long-acting fertilizer as main,, high yield tree many to bearing fruit should suitably be supplemented available N fertilizer.

(2) dredge the spring tip, control summer shoot, short autumn growth.Dredge and remove the part spring tip, reduce nutrient consumption.Adopt the manual method early summer shoot of erasing, to the strong tree of green grass or young crops, can put slow summer shoot.Autumn growth is the main bearing basal shoot of rock sugar tangerine, autumn growth enriches with no, be directly connected to yielding positive results of the coming year, thereby will extremely focus on doing a good job of it autumn growth and urge to put management, put the shady and cool weather during the tip time generally is selected in the Limit of Heat to White Dew, before putting the tip, within 7-10 days, once prune, cutting back is strengthened the tip, to large annual bearer, takes to change the tip (wiping out fruit on the strong tip) with fruit, to guarantee enough healthy and strong autumn growths, and carry out bud picking and put the tip.The tip in White Dew can be put in young strong tree, the orchard that rich water quality management is good, and putting the tip time can not be too early or excessively slow, puts too early the tip, may take out the winter tip, and crossing delayed release tip autumn growth can not be aging, affects flower bud differentiation.

(3) promote flower bud differentiation.Fertile by executing before and after fruit picking, water processed after autumn growth is aging, in conjunction with ploughing deeply the measure of grade of being completely cured of improving the soil, suppress winter tip growth, raising resin concentration, promotion flower bud differentiation.

(4) flower and fruit protecting.1. thank and spend 1-2 5-8PPM2.4-D of 2/3 beginning spray, improve percentage of fertile fruit.2. the tip is really fought for nutrient, is the main cause that affects percentage of fertile fruit, and particularly children orchard in age, without spending the spring tip long, consume nutrient very large, affects floral organ and young fruit development and causes a large amount of fruit drops, therefore should suitably remove.3. extract in time early summer shoot, to reduce the tip, really fight for nutrient.4. enrich fertilizer and top dressing, young fruit period, except execute fruit retention fertilizer in April, sprays 2-3 0.3% urea simultaneously and adds 0.2% potassium dihydrogen phosphate, adds 0.1% borax and 0.1% magnesium sulfate, to improve percentage of fertile fruit.

(5) winter pruning.Winter, the appropriateness cutting back was one of key measure of downgrading the dense planting stable yields, but prune principle and take light pruning as main, in conjunction with clear garden in winter, wipe out deadwood, sick branch, intersection branch, cutting back water sprout, descending branch, slim and frahile branch, and planned to the 5-9 level part branch cutting back that bounced back, the clip rugosity is controlled at 1 centimetre of left and right.Retain greenery branch layer as far as possible, keep ventilation and penetrating light in tree crown, keep tree crown independence.

Adopt the present invention, within after the field planting of rock sugar tangerine fruit tree the 3rd year, enter the operation initial stage, the 3-5 kilogram is produced in average strain, the 4th year per plant 5-10 kilogram, become annual bearer per mu yield 2500-3000 kilogram, most of tree height is controlled at 1.5-1.7 rice left and right, and the tree crown width is between 1.6-1.9 rice.The orchard stable yield.
