Abstract
The invention relates to a method for drawing branches of a direct seeding and orchard constructing inter-trunk solid-planted young date tree. The method comprises the following steps: selecting and keeping a permanent trunk at intervals of 1.0 meters in a date tree direct seeding line in a direct seeding and orchard constructing inter-trunk solid-planted young date tree garden in mid-May and removing the tops when date tree branches grow to between 30 and 40 centimeters; pulling main branches of the remaining young trees towards both sides by using a rope or a steel wire, controlling a branch pulling angle to be between 60 and 70 degrees and fixing the branches by using wood piles to prevent the date heads from sprouting, enlarge illumination space of grafted seedlings and promote blossoming and fruit bearing; and performing conventional cultivating management. Branch pulling among the trunks is performed to remarkably improve illumination environment in tree crowns of the direct seeding and orchard constructing young date tree, reduce invalid light region and enhance ventilation and light transmission state of tree bodies. After branch pulling treatment, the yield and quality of dates are effectively enhanced.
Description
Technical field
The present invention relates to the method for drawing branches in the jujube cultivation technology of ring oasis, Tarim Basin, Xinjiang.
Background technology
Drawing branch is the normal method that adopts in the fruit tree shaping pruning, and the economic benefit of fruit tree efficiently being cultivated reasonable utilization cultivation step, raising fruit quality and output, increase orchard worker in the research has important actual directive significance.Forefathers draw the effect and the mechanism of branch to carry out more research for fruit tree, but draw a technical research to yet there are no report to the young date tree in dense planting jujube garden between live strain of building the garden formula.
Jujube (Ziziphus jujube Mill.) is an intolerant tree species, in China cultivation history in several thousand is arranged, and is the distinctive fruit tree resource of China, Chinese first dry fruit and the seventh-largest fruit tree.Because jujube has shown splendid growth adaptability and high yield and high quality performance in Xinjiang.Since 2006, ring oasis, Tarim Basin band jujube planting scale development speed is swift and violent.In order to improve the survival rate and the storage rate of jujube plantation, nearly 2 years, the live garden (1 year sowing wild jujube, kind grafting in 1 year) of building day by day became the main developing direction that jujube is planted, and its seeding row spacing adopts 0.25m * 4m more.This pattern major advantage is " forest form is neat, high density and high benefit ", but the problem that exists is: overstocked between second and third year strain after the grafting, transplant comparatively difficulty, and effectively photosynthetic area reduces, and single plant yield reduces, and jujube fruit matter descends.For this reason, under the prerequisite of effective strain number that does not reduce dense planting children jujube garden in age between live strain and raising output, researched and developed live " draw between strain branch, reserve permanent strain " technology of building formula jujube garden, garden---promptly young date tree is taked to keep at a certain distance away in capable and choose the permanent strain of a strain, all the other produce strain successively toward two layback branches as joining, to improve jujube fruit quality and yield, improve the jujube high-yield high-grade culture technique.
Summary of the invention
The objective of the invention is to, the method for drawing branches of a kind of direct seeding and orchard constructing inter-trunk solid-planted young jujube tree is provided.This method is that young age of dense planting between live strain is in the jujube garden, in blooming early stage, in the live row, keep permanent strain, all the other strains are produced strain toward two layback branches as joining, and to improve between live strain between the garden strain of dense planting jujube photoenvironment in the canopy, reduce invalid light district, improve tree body ventilation and penetrating light situation, so that improve jujube fruit yield and quality.
The method for drawing branches of direct seeding and orchard constructing inter-trunk solid-planted young jujube tree of the present invention follows these steps to carry out:
A, select direct seeding and orchard constructing inter-trunk solid-planted jujube garden in young age for use, spacing in the rows is 0.25m, and line-spacing is 4m;
B, keep permanent strain: in the plantation row, keep 1 permanent strain every 1.0m the mid-May before jujube tree blooms, jujube head branch growth carries out pinching during to 30-40cm;
C, draw branch: to keeping the treelet beyond the permanent strain in the row, with rope or iron wire the treelet major branch is drawn back to both sides successively toward both sides, and fix on ground with timber, pinching simultaneously suppresses the jujube head growth, promotes to blossom and bear fruit the interior photosynthetic active radiation of canopy between the increase strain;
D, control measures: carry out conventional cultivation management then and get final product.
Step c draws an angle to be controlled at 60 °-70 °.
The present invention compared with prior art has the following advantages and distinguished effect:
1. objective for implementation of the present invention is direct seeding and orchard constructing inter-trunk solid-planted jujube garden in young age, and is different from an object that draws of general introduction;
2. the present invention compares with an existing technology of drawing, " draw branch between strain, reserve permanent strain " technology of direct seeding and orchard constructing inter-trunk solid-planted young date tree has been proposed, improved the yield and quality of direct seeding and orchard constructing inter-trunk solid-planted jujube tree, perfect oasis, ring Tarim Basin band jujube high-yield high-grade culture technique.
Embodiment
Embodiment 1
The method for drawing branches of direct seeding and orchard constructing inter-trunk solid-planted young jujube tree of the present invention, test site are positioned at Aksu City Top Lu Ke township 1 squad of 10 groups dense planting children jujube garden in age between live strain of building the garden, coordinate be 40 ° 56 of north latitude ', 80 ° 06 of east longitude '.This garden jujube tree is the wild jujube seedling of sowing in 2007, grafting fine horse jujube in 2008, and seeding row spacing is 0.25 * 4m, density is 10005 strains/hm
2, closing between strain in 2009.Test procedure:
A, select direct seeding and orchard constructing inter-trunk solid-planted jujube garden in young age for use: 1 year sowing wild jujube, 1 year grafting fine horse jujube drew branch on the 3rd year;
B, keep permanent strain: in the jujube plantation row, keep 1 permanent strain the mid-May before jujube tree blooms, during jujube head branch growth 30-40cm, carry out pinching and handle every 1.0m;
C, draw branch: to planting the treelet that keeps in the row beyond the permanent strain, with rope or iron wire the treelet major branch is drawn back to both sides successively toward both sides, draw an angle to be controlled at 60 °-70 °, and fix on ground with timber, injured in order to prevent branch, position at branch tether or iron wire, can fill up lining thing (as cloth etc.), carry out the pinching of jujube head simultaneously, promote to blossom and bear fruit, increase grafting illumination space, increase the interior photosynthetic active radiation of canopy between strain;
D, control measures: carry out conventional cultivation management then and get final product.
By the enforcement of the method, plantation leaf area index in the ranks improves 119.0%, and light transmittance improves 1 times between strain, and luminous environment obviously improves; Draw the longitudinal and transverse demeter of a back fruit to become big, single fruit weight and single plant yield amplification are respectively 3.57%, 16.05%; Jujube fruit total reducing sugar and total acid content have improved 24.84% and 7.80% respectively.
Therefore,, can improve the economic benefit at plantation family, promote of the long-run development of jujube industry in this area by the mode of " draw branch between strain, reserve permanent strain " in the direct seeding and orchard constructing inter-trunk solid-planted jujube garden in young age of ring oasis, Tarim Basin band.
