Abstract

The invention discloses a blueberry root domain space covering cultivation method which comprises the steps as follows: adopting a planting furrow covering method or a planting hole covering method, covering the interior of the planting furrow with crop straws, sawdust or pine needles, laying microporous permeable non-woven fabrics on all walls and the bottom of the planting furrow, and using plastic films to partition the non-woven fabrics on all walls of the planting furrow, planting blueberry seedlings, wherein the root system of the blueberry seedlings cannot penetrate through the non-woven fabrics, filling the nutrient soil to the planting furrow and performing fix planting of the blueberry seedlings, and covering overground parts of the blueberry seedlings after fixing planting with the crop straws, sawdust or pine needles with certain height, wherein the pH value of soil is stabilized within the range of 4.5-5.7. Therefore, the blueberry root domain space covering cultivation method is simple to operate, the purpose of improving blueberry planting soil can be achieved only with lower cost, the influence on growth of blueberries due to inappropriate soil conditions is avoided, the soil has favorable permeability, the blueberries grow well, the fruit quality is improved, and the blueberry root domain space covering cultivation method is very conducive to production of organic fruit products and expansion of planting range of the blueberries.

Description

A kind of blueberry root-zone space mulching and planting method

Technical field

The invention discloses a kind of blueberry cultivation method.Be a kind of blueberry root-zone space mulching and planting method specifically, utilize blueberry root growth characteristics, distribution space and, to the soil condition requirement, reduce soil pH value too high, guarantee that again soil has good permeability simultaneously.

Background technology

Blueberry is that a kind of economic worth is high, the emerging fruit tree that development potentiality is large, but because it requires harshness to soil, the acid ground that happiness is loose, the content of organic matter is high, and the most soil meta-alkalis of China or neutrality have limited its cultivation scope.In producing at present, adopt used the acidic fertiliziers such as sulphur, ferrous sulfate more, and add in a large number organic manure and improve soil, but due to the impact that is subjected to the surrounding soil environment, soil pH value can raise gradually, cause repeatedly applying acidic fertilizier, this has not only improved the cost of blueberry plantation, and the acidic fertiliziers such as the excessive sulphur that applies, ferrous sulfate easily cause serious environmental pollution, and is especially very big to the pollution of agricultural water; Although and adopt traditional potted plant mode short-term to solve the too high problem of soil pH, but the potted plant soil compaction that often causes, the soil permeability gas permeability descends, and potted plantly can not apply on a large scale aborning, therefore can not fundamentally solve the higher problem of soil pH value in the blueberry plantation, how to solve soil pH value too high, guarantee again that it is the subject matter in the blueberry plantation that soil has good permeability simultaneously.

Summary of the invention

In view of above-mentioned present situation, the present invention belongs to undershrub according to blueberry, the root system mean level is distributed in the view field of tree crown, the degree of depth is in the rhizosphere solid space of 30-45cm, the inventor is according to these growth characteristics of blueberry, and require acid, gas permeability and drainage is good, the content of organic matter is high soil condition in conjunction with it, changes the blueberry cropping pattern of improving the soil in traditional potted plant and land for growing field crops, and the blueberry root-zone space mulching and planting method of proposition.

The present invention includes following method:

1, at first on the ground of planting, dig the planting furrow that 50cm is wide, 70cm is dark, or dig the planting hole that 50cm is long, 50cm is wide, 70cm is dark;

2, at the nonwoven of planting furrow wall and bottom place mat microporous permeable, with plastic film, the nonwoven of planting furrow wall is separated;

3, in the planting furrow of place mat nonwoven, cover crops straw, wood chip or the pine needle material that 20cm is dark, then in planting furrow, fill out Nutrition Soil 40-50cm;

4, field planting blueberry seedling;

5, by planting furrow Nutrition Soil top cover crop stalk, wood chip or pine needle material after field planting, cover height 5-10cm, soil pH is stabilized in 4.5-5.7.

The Nutrition Soil of indication of the present invention, comprise that the proportioning of field soil, river sand, the peat composed of rotten mosses is: 2: 1: 1.

Effect of the present invention is: by by blueberry root-zone space surrounding and the isolation of surrounding soil ambient level, make the blueberry root growth in the environment of relative closure, reduce the impact of surrounding soil environment on blueberry rhizosphere soil pH; The bottom, space isolates with the micropore nonwoven of water-permeable and air permeable, the root-zone space top and the bottom cover with crops straw, wood chip or pine needle simultaneously, guarantee that the rhizosphere vertical space communicates with the external world, guarantee the water-permeable and air permeable of root-zone space, simultaneously cushion again the interference of external environment to rhizosphere soil, increased the preservation capacity of water and fertility of soil, effectively improved the also physicochemical property of stable soil, the stable 4.5-5.7 left and right that remains on of soil pH value, for the blueberry growth provides suitable soil condition.This technology is easy to operate aborning, and cost is low, and water-saving is economized fertile laborsaving, and environmental friendliness, to producing Organic Fruit, enlarges the blueberry planting range all very favourable.

After adopting the rhizosphere soverlay technique: the average plant height of blue rich blueberry reaches 1.64m, average fruit footpath 1.56cm, and mean fruit weight 2.98g, average soluble solid reach living strain in 12.5%, four year and produce blueberry 1.54kg.Every mu can be reduced fertilizer and pesticide and drop into more than 2000 yuan, 3000 yuan of service charges.
