Abstract

The present invention discloses a soil improvement method of yellow soil and red sand stone. The soil improvement method comprises the following steps of: (1) applying organic fertilizer and livestock fertilizer to improve the soil structure in spring to autumn, planting paddy rice, and culturing fishes between the paddy rice; (2) applying phosphate fertilizer, potash fertilizer, livestock fertilizer and edible fungi residue in winter, and planting strawberry by using greenhouses; (3) mixing the yellow soil and the red sand stone according to some proportion after the strawberry is shipped to the market in the next year; and (4) adjusting the proportion of the yellow soil and the red sand stone year by year to enable pH value of the soil to be greater than 6.0 and less than 7.5. According to the soil improvement method, through applying the fertilizers, the soil structure is improved, and the soil nutrient is coordinated; utilization rate of the fertilizer is increased, and utilization of the phosphor and potash fertilizers and crop plantation are cooperated to improve the soil structure; and finally the yellow soil and the red sand stone are mixed, the proportion of the yellow soil and the red sand stone is adjusted year by year to enable the pH value of the soil to be greater than 6.0 and less than 7.5, so that the soil is improved.

Description

The soil improvement method of yellow soil and red sand stone

Technical field

The present invention relates to a kind of soil amelioration techniques, particularly the improvement method of a kind of yellow soil and red sand stone.

Background technology

Existing yellow soil soil major part is acid, and general pH value is 4.0 ~ 5.5, and quality is sticky heavy, and shallow, the easy drought of structural difference, tilth is easily flooded; Effective fertility is low, permeability is poor, nutrients release is slow; Bad tilth, difficulty plough again difficult rake, soil acidity is higher, available phosphorus content is low, and existing soil of growing formation mostly is sandy soil, has lime reaction in various degree, the micro-alkalescence of soil is to alkalescence, and red sand stone is Red Sandstone waste outwash or residual deposit, is distributed in each several part in field, for rufous, husky earth is to light earth, and pH value is 8.1, soil layer thinner (thickness is at 35 ~ 65cm), soil profile is grown not obvious, soil nature is cold, preserve moisture and fertility ability, sends out seedling and does not send out Lao Miao.

The soil improvement method of existing basic yellow earth and red sand stone is generally add acid chemical in soil, as added Cosan, ferrous sulfate etc., although soil melioration can be become neutral or subacidity soil by this improvement method, but the soil fertility after improvement is still poor, can not provide more sufficient nutrition for plant growth.

Summary of the invention

In view of this, the object of this invention is to provide the soil improvement method of a kind of yellow soil and red sand stone, the soil improvement method of this yellow soil and red sand stone improves the structure of soil by fertilising, coordinate the nutrient of soil; Improve the availability of fertilizer, with the use of the fertilizer such as phosphorus, potash fertilizer, proportion of crop planting, the structure of improvement soil; Finally yellow soil and the blending of red sand stone, adjust the ratio of yellow soil and red sand stone year by year, make the acid-base value of soil be greater than 6.0, be less than 7.5, reach the object of improvement soil.

In order to solve above-mentioned technical problem, the soil improvement method of a kind of yellow soil of the present invention and red sand stone, its step is as follows:

1) in spring to autumn, improve the structure of soil to yellow soil soil applying organic manure and family's animal manure, rice cultivation, carry out breeding fish between rice;

2) in the winter time, increasing the p application rate, potash fertilizer, family's animal manure and edible fungi residues, adopt greenhouse gardening strawberry;

3) Second Year is after strawberry listing, and add red sand stone, red sand stone and yellow soil are proportionally admixed, applying organic manure and family's animal manure improve the structure of soil, at Second Year then rice cultivation in spring to autumn, carry out breeding fish between rice,

4) adjust the ratio of yellow soil and red sand stone year by year, make the acid-base value of soil be greater than 6.0, be less than 7.5.

Further, in step 1) in, described animal manure is pig manure after fermentation and cow dung, and is sprinkled upon in yellow soil field by 3 ~ 5 tons/mu.

Further, in step 1) in, after rice cultivation, between rice, cultivation throws in river snail, swamp eel and earthworm, for breeding fish between rice.

Further, in step 3) in, by red sand stone and yellow soil according to 8: 2 ratio admix.

Further, in step 4) in, the addition of every mu, red sand stone is reduced by 10% year by year.

Beneficial effect of the present invention:

The soil improvement method of yellow soil of the present invention and red sand stone improves the structure of soil by fertilising, coordinate the nutrient of soil; Improve the availability of fertilizer, with the use of the fertilizer such as phosphorus, potash fertilizer, proportion of crop planting, the structure of improvement soil; Finally yellow soil and the blending of red sand stone, adjust the ratio of yellow soil and red sand stone year by year, make the acid-base value of soil be greater than 6.0, be less than 7.5, reach the object of improvement soil.

Embodiment

Below in conjunction with embodiment, the invention will be further described.

The soil improvement method of a kind of yellow soil of the present invention and red sand stone, its step is as follows:

1) in spring to autumn, the structure of soil is improved to yellow soil soil applying organic manure and family's animal manure, rice cultivation, carries out breeding fish between rice, and described animal manure is pig manure after fermentation and cow dung, and be sprinkled upon in yellow soil field by 3 ~ 5 tons/mu, after rice cultivation, between rice, cultivation throws in river snail, swamp eel and earthworm, for breeding fish between rice, the present embodiment improves the structure of soil by fertilising, coordinates the nutrient of soil; Improve the availability of fertilizer, with the use of the fertilizer such as phosphorus, potash fertilizer, proportion of crop planting, the structure of improvement soil, is improved the output of breeding fish, utilizes swamp eel and earthworm to burrow by river snail, swamp eel and earthworm, improve soil effective fertility, improves soil permeability.

2) in the winter time, increasing the p application rate, potash fertilizer, family's animal manure and edible fungi residues, adopt greenhouse gardening strawberry, and this structure is conducive to the nutrient coordinating soil; Improve the availability of fertilizer, increase the value in soil, carry out economic extra earning.

3) Second Year is after strawberry listing, add red sand stone, red sand stone and yellow soil are proportionally admixed, preferably the addition of every mu, red sand stone is reduced by 10% year by year, applying organic manure and family's animal manure improve the structure of soil, at Second Year then rice cultivation in spring to autumn, carry out breeding fish between rice, finally yellow soil and the blending of red sand stone, adjust the ratio of yellow soil and red sand stone year by year, make the acid-base value of soil be greater than 6.0, be less than 7.5.

4) adjust the ratio of yellow soil and red sand stone year by year, the addition of every mu, red sand stone is reduced by 10% year by year, makes the acid-base value of soil be greater than 6.0, be less than 7.5, reach the object of improvement soil.

What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
