Abstract
The invention relates to a root cutting and high-yield method for nutrition control of a winter jujube tree, which comprises the following steps of: (1) controlling the humidity and time; (2) cutting and girdling; (3) controlling the humidity and fertilizer application; and (4) bud picking. The method has the advantages that the excessive growth of the tree is controlled, the operation is simple, and the method is convenient to popularize and apply in the rural areas; the yield is increased by about 30%, the acre yield is increased by about 500 kg according to 110 plants per mu, and the net benefit of yield per mu is increased by over 2000 yuan; and the economic benefit is improved, the industrial scale is broad, the initiative of farmers is improved, and powerful guarantee is provided for eliminating barren for afforestation.
Description
Technical field
The present invention relates to the agriculture forestry planting technical field, the jujube tree nutritional control is cut the root high yield method a kind of winter specifically.
Background technology
Along with the enforcement of country's conceding the land to forestry policy, from 2000, a lot of local counties and cities, the whole nation particularly southern area (is example with the Xiaochang County, Hubei Province) introduced the winter jujube that northern area is planted for many years, plant with annual 2000 mu speed.So not only reduced barren hill, hillock, can allow the masses increase income again.But there is following technical barrier in the winter jujube planting process:
⑴ tree vigo(u)r over growth: former northern area is dry, and the Xiaochang County is located in the Yangtze river basin, and is with heavy rainfall, and soil moisture is bigger, causes the growth of jujube tree tree vigo(u)r obvious prosperous excessively;
⑵ output is on the low side: in a single day tree vigo(u)r crosses prosperous growth, and formed flowers and fruits very easily come off, and cause output very low;
⑶ control nutrition dynamics is not enough behind the band girdle: can reach the purpose of the prosperous length of control behind the general winter jujube tree band girdle, and when for more fertile growing area, its DeGrain;
⑷ economic benefit is on the low side: 0.07 hectare winter jujube average yield is that economic benefit is on the low side about the 500-800 kilogram at present, and peasant's enthusiasm is generally not high.
Summary of the invention
The objective of the invention is to develop a kind ofly increase output, increase economic efficiency, winter jujube tree nutritional control simple to operate cuts the root high yield method.
Winter jujube tree nutritional control of the present invention is cut the root high yield method, and its step is as follows:
⑴ controlled humidity and opportunity: after entering the May, pay close attention to and grasp the soil moisture content in jujube garden, as arid weather, a week is irritated semlsulcus water in advance, and water in time carries out after doing; As continuous rainy weather, find opportunity cutting accurately, not deferrable clipping time;
⑵ cut, band girdle: clipping time must be between 15-May 20 May, is as the criterion with the jujube tree early flowering season, and it is 10-15cm that jujube hangs length; Along tree row vertically, apart from both sides, trunk 70-120cm place, 30 ° of incision 40-50cm get final product with tool tilt, and the cut-out root system is cut the slit behind the root, covers reality again with soil, avoid rain penetration to rot root, also are convenient to root of hair in the future;
⑶ controlled humidity, fertilising: cut behind the root as arid, must in time pour water, guaranteeing all the time has moisture in the soil; As a run of wet weather, do ditch cleaning row stain well; Every tree is executed fruit-specific fertilizer 2-3 jin with the interior fruit-promoting fertilizer of executing to cut behind the root 25-30 days;
⑷ bud picking: still there is new jujube bud to grow after cutting root, the new jujube bud of manually erasing, its effect of bearing fruit is better.
Described fruit-promoting fertilizer is the compound potassium sulfate fertilizer (fruit tree special use) that Hubei Yangfeng Stock Co., Ltd produces and sells.
The advantage that winter jujube tree nutritional control of the present invention is cut the root high yield method is: the control tree vigo(u)r is crossed prosperously and grown, and is simple to operate, conveniently applies in the rural area; Increase output, output can improve about 30%, calculates by every mu 110 strain, and its per mu yield has a net increase of about 500 kilograms, and the per mu yield benefit has a net increase of more than 2000 yuan; Increase economic efficiency, industry size advances more wide, improves peasant's enthusiasm, and the waste afforestation achievement of going out can obtain more strong guarantee.

Experimentation and effect:
1, in early June, 2008, promptly before and after the 10th day behind the band girdle, eugonic tree is subtracted the tip handle, vigorous tip length is controlled at about 10-20cm, and purpose is that the control shoot growth reaches the flower and fruit protecting purpose, but after 3-5 days, jujube hangs and continues to sprout sprouting, and effect is undesirable, and it is invalid to test;
2, between-20 days on the 15th May in 2009, on the occasion of the jujube tree early flowering season, select eugonic 30 trees, in tree row one side, apart from trunk 90cm place cutting root, degree of depth 40-50cm cuts the root ratio and accounts for about 25% of full tree, and the cutting back was carried out band girdle on the 5th day.Find through observing: jujube hangs growth obviously slowly, and fruit-setting rate improves about 10%;
3 ,-20 days on the 15th May in 2010, take and above-mentioned identical cutting method, select to carry out in 2009 30 trees of experiment, both sides at the tree trunk, cut root apart from doing the 90cm place along the longitudinal, cut the root degree of depth still for 40-50cm, the cutting ratio changes 50% of whole tree into must lateral root, cuts behind the root the 5th day and carries out band girdle.Find through observing: shoot growth is extremely slow, and fruit-setting rate improves about 30%.
Concrete output sees the following form:
Experimental results show that: after originally cutting the method for root application, output improves about 30%, calculates by every mu 110 strain, and its per mu yield has a net increase of about 500 kilograms, and the per mu yield benefit has a net increase of more than 2000 yuan.
