CN105941041A - Cultivation method for promoting early fruiting and high yielding of pear trees - Google Patents

Abstract

The invention discloses a cultivation method for promoting early fruiting and high yielding of pear trees. The cultivation method comprises following steps: field selecting, deep tillage, base fertilizer applying, hole digging, seed sowing, fertilizer applying, field planting, trimming, branch thinning, flower thinning, leaf thinning, foliar dressing and watering. By means of the method, base fertilizer is applied to promote the robust growth of the pear trees, to increase the stress resistance, and to fully guarantee the nutrient annually required by growth; ripe peaches are large in size, vivid in color, good in taste and high in yield; different fertilizer applying methods in the growth period can guarantee the reasonable utilization of fertilizer effect, increase the fertility of the fertilizer, and quicken the fertilizer effect; the method has small investment, fertilizer amount is saved, cost is saved and yield increases by 10% to 15%.

Description

A kind of cultural method promoting pear tree early to tie high yield

Technical field

The present invention relates to agricultural plantation technology field, particularly relate to a kind of cultural method promoting pear tree early to tie high yield.

Background technology

Pear tree is Rosaceae pear, perennial deciduous fruit tree, and arbor has in the whole world and is distributed widely.Edible fruit use, There is the highest nutrition and medical value.

Pears, fruit title, Rosaceae Pyrus L, perennial deciduous tree fruit tree, leaf is avette, spends the whitest, typically The color of pears is that crust presents golden yellow or warm yellow, and the inside sarcocarp is then well-illuminated white, fresh and tender succulence, and taste is sweet, core The micro-acid of taste, cool sexuality；Pears are distributed in North China, northeast, northwest and Yangtze river basin each province；7～JIUYUE between fruit maturation time gather, can Using fresh herb or section are dried.

Pear tree well developed root system, vertical root is deeply up to more than 2-3m, and horizontal branch is distributed more widely, is about hat about 2 times.Happiness light Happiness temperature, preferably selects soil layer gentle slope deep, well-drained mountain planting, especially with sand loam mountain region as ideal.Dryness is strong, layer More apparent.Early, fruiting period is long, and some kind 2-3 i.e. starts result, and the best fruiting period can maintain more than 50 years for result.

Summary of the invention

Through the spy meter for many years pear tree cultivated, draw a set of pear tree cultural method, the invention provides a kind of promotion pears Tree early ties the cultural method of high yield.

The technical solution adopted in the present invention is:

A kind of cultural method promoting pear tree early to tie high yield, its cultural method comprises the steps:

Selection of land gesture is smooth, and soil layer is deep, the soil is porous, milpa is made in well-drained field, during early winter applies field Become thoroughly decomposed feces and Realgar, carry out ploughing deeply of degree of depth 50-60cm；

The deep 80-85cm of planting pit before rudiment in early spring, diameter 1m, spacing 4m, discharge 10-15cm thickness biogas residue layer, biogas residue in every cave Discharge 5cm thickness compound fertilizer on Ceng, calcium, fertiliser containing magnesium mix fine sand soil layer, and compound fertilizer, calcium, fertiliser containing magnesium, the weight ratio of thin sand and soil are 3:0.2: 0.2:35, the nitrogen of compound fertilizer, phosphorus, potassium, than for 15:15:25, carry out field planting earthing and water；

Surely do during seedling field planting, heading height 40-50cm, ground floor major branch number 3-4, second layer major branch 2-3, Third layer major branch 1-2, highly 2-2.2m, the top tip falls head, ground floor and second layer spacing 1m, the second layer and third layer spacing 55cm, every interlayer major branch is interlaced；

Winter cuts and removes brachyplast, fruit branch and too much bud, and one excision between bud on branch, on branch, 18-22cm stays one Inflorescence, each inflorescence stays 2-3 alabastrum, first extracts disease pest fruit, malformed fruit, small and weak fruit, removes weak branch in 15 days after fallen flowers On young fruit, retain fruit with blade ratio for 35:1；

July, the urea solution of 2-3 0.2-0.3% was even sprayed on blade face, was spaced 20 days, and spraying concentration August is 0.2-0.3% phosphoric acid Potassium dihydrogen 2-3 time, is spaced 15 days；

After field planting 20 days interval within 20 days, water permeable once, mid-August, stopping was watered, and watered permeable surviving the winter by the end of October.

Beneficial effects of the present invention: promoted the healthy and strong growth of pear tree by basal dressing, improve resistance, fully ensured that complete The growth in year need to use nutrient, and the peach fruit in period of maturation is big and bright-coloured, and mouthfeel is good, and yield is high, and the Different Fertilization mode of trophophase ensures The Appropriate application of fertilizer efficiency, fertility utilization rate is high, and fertilizer efficiency is quick, less investment, saves dose, thus cost-effective, increases production on year-on-year basis 10-15%。

Detailed description of the invention

A kind of cultural method promoting pear tree early to tie high yield, its cultural method comprises the steps:

Selection of land gesture is smooth, and soil layer is deep, the soil is porous, milpa is made in well-drained field, during early winter applies field Become thoroughly decomposed feces and Realgar, carry out ploughing deeply of degree of depth 50-60cm；
