Abstract

The invention discloses a soil improving method. The soil improving method comprises the following steps: increasing a decomposed organic fertilizer to improve lean soil; and mixing the decomposed organic fertilizer with an soil improving agent to obtain a mixture, uniformly spraying the mixture to the surface of leveled soil, and turning the mixture under the soil, wherein the dosage of the decomposed organic fertilizer is 1200kg per mu. According to the soil improving method disclosed by the invention, the pH and other physical and chemical properties of the soil are improved by regulating the formula of the soil improving agent, so that heavy metals generate reactions such as precipitation, chelation and the like, thereby reducing bio-availability of the heavy metals, reducing absorptive amount of crops to the heavy metals, improving the quality of agricultural products and achieving subsidiary function to restoration of heavy metal contaminated soil.

Description

A kind of soil improvement method

Technical field

The invention belongs to agricultural technology field, specifically a kind of soil improvement method.

Background technology

In most of vegetable-growing area, all there is the long-term unreasonable phenomenon using chemical fertilizer in a large number, not only base fertilizer fertilizer application amount is large, and to topdress also be a large amount of uses, soil aggregate is made to destroy so serious, gas permeability reduces, and the microbial activity of aerobism declines, and soil-ripening is slow, thus cause soil compaction, in soil, salt ion increases, and hinders vegetable root system normally to absorb water, affects plant strain growth; Meanwhile, the shortage of the trace element such as Iron in Soil zinc boron, also greatly can affect growing of vegetables, cause production declining.Improve soil is the effective ways improving soil compaction.

Summary of the invention

The object of the invention is to overcome prior art defect, a kind of soil improvement method is provided.

Object of the present invention can be achieved through the following technical solutions:

A kind of soil improvement method, comprises the following steps:

(1) fertilizer become thoroughly decomposed is enriched, improvement lean soil, the described fertilizer become thoroughly decomposed is prepared by the following method: dish root, dish leaf adhesive tape are encapsulated, imbed dell 10-20 days, by the weight ratio of 1:10, sheep excrement and chicken manure are mixed into fermentation vat, in fermentation vat, add the dish root after buried process and dish leaf, temperature remains on 35-40 DEG C, sealing and fermenting 45 days, obtains the fertilizer become thoroughly decomposed;

(2) fertilizer become thoroughly decomposed is mixed with soil conditioner, evenly spread fertilizer over the fields the surface, soil with smooth mistake, and plough under in soil, the consumption of the fertilizer become thoroughly decomposed is every mu of 1200kg, wherein, soil conditioner is made up of the component of following weight portion: 50 parts, flyash, ash 30 parts, 15 parts, ammonium phosphate, ammonium chloride 8 parts, 12 parts, potassium chloride, 5 parts, magnesium sulfate, citric acid 3 parts, polyacrylamide 1.8 parts, humic acid 5 parts, 20 parts, urea, 4 parts, diatomite.

The weight ratio of the fertilizer that described step (2) is become thoroughly decomposed and soil conditioner is 100:1.

Beneficial effect of the present invention: the inventive method changes pH and other physicochemical property of soil by the formula adjusting soil conditioner, the reactions such as heavy metal precipitates in soil, chelating can be made, reduce its biological effectiveness, reduce the absorptive amount of crop heavy metal, improve the quality of agricultural product, also the reparation of heavy metal contaminated soil has booster action.

Embodiment

For the ease of it will be appreciated by those skilled in the art that the present invention is further illustrated below in conjunction with specific embodiment.

Embodiment 1

Soil improvement method: enrich the fertilizer become thoroughly decomposed, improvement lean soil, this fertilizer become thoroughly decomposed is prepared by the following method: dish root, dish leaf adhesive tape are encapsulated, imbed dell 20 days, by the weight ratio of 1:10, sheep excrement and chicken manure are mixed into fermentation vat, in fermentation vat, add the dish root after buried process and dish leaf, temperature remains on 40 DEG C, sealing and fermenting 45 days, obtains the fertilizer become thoroughly decomposed.

The fertilizer become thoroughly decomposed is mixed with the weight ratio of 100:1 with soil conditioner, evenly spread fertilizer over the fields the surface, soil with smooth mistake, and plough under in soil, the consumption of the fertilizer become thoroughly decomposed is every mu of 1200kg, wherein, soil conditioner is made up of the component of following weight portion: 50 parts, flyash, ash 30 parts, 15 parts, ammonium phosphate, ammonium chloride 8 parts, 12 parts, potassium chloride, 5 parts, magnesium sulfate, citric acid 3 parts, polyacrylamide 1.8 parts, humic acid 5 parts, 20 parts, urea, 4 parts, diatomite.

Be rich in various trace elements needed for nitrogen, phosphorus, potassium and crop in fertilizer of the present invention, have and have obvious the effect of increasing income.Due in arviculture process, use chemical fertilizer year after year, not only cause soil compaction, fertilizer efficiency day subtracts, also pollute environment, the present invention is not only the energy that agricultural production provides new, also effectively improve Cultivated-land Fertility, improve the feature of fertilizer provision from soil environment, the spore exo polysaccharides produced in fertilizer is the adhesive of soil aggregate, can chesson, strengthen soil aggregate, improve water retention capacity, increase the soil organic matter, activating soil, increase fertilizer efficiency, assist effect of potential nutrients in release soil, the noisy soil of activation nutrient pine, strengthen the gas permeability of soil, be conducive to crop root growth, improve vitality and the immunity of crop.

Embodiment 2

Soil improvement method: enrich the fertilizer become thoroughly decomposed, improvement lean soil, the described fertilizer become thoroughly decomposed is prepared by the following method: dish root, dish leaf adhesive tape are encapsulated, imbed dell 10 days, by the weight ratio of 1:10, sheep excrement and chicken manure are mixed into fermentation vat, in fermentation vat, add the dish root after buried process and dish leaf, temperature remains on 35 DEG C, sealing and fermenting 45 days, obtains the fertilizer become thoroughly decomposed.

The fertilizer become thoroughly decomposed is mixed with the weight ratio of 100:1 with soil conditioner, evenly spread fertilizer over the fields the surface, soil with smooth mistake, and plough under in soil, the consumption of the fertilizer become thoroughly decomposed is every mu of 1200kg, wherein, soil conditioner is made up of the component of following weight portion: 50 parts, flyash, ash 30 parts, 15 parts, ammonium phosphate, ammonium chloride 8 parts, 12 parts, potassium chloride, 5 parts, magnesium sulfate, citric acid 3 parts, polyacrylamide 1.8 parts, humic acid 5 parts, 20 parts, urea, 4 parts, diatomite.
