Problems solved by technology

The problem or shortcoming of prior art: although the way of washing out salinity with above-mentioned water can wash away redundant salinity, correct the pH value of soil, but also wash away most of soil nutrient simultaneously, have seriously reduced the fertility of soil

Embodiment Construction

[0013] Hereinafter, the present invention will be described in detail with reference to examples.

[0014] In the method for improving soil of the present invention, the saline-alkali soil is rinsed or rinsed with clear water to remove excess saline-alkali and become soil with a pH value of 6-7; use organic matter to produce organic fertilizers with microbial populations; then detect the soil Nitrogen, phosphorus, potassium and other trace elements necessary for crop growth; then, according to the element content of the soil and the needs of the crops to be cultivated, the quantitative organic fertilizer and slow-release chemical fertilizer are evenly infiltrated into the soil.

[0015] The microbial population includes yeast, actinomycetes, photosynthetic bacteria, nitrogen-fixing bacteria, and phosphorus- and potassium-solubilizing bacteria. Each gram of fertilizer contains 0.2-0.5 billion effective viable bacteria; organic matter comes from livestock manure, cotton cypress, ...

Abstract

A soil improvement method comprises the steps of leaching or washing saline soil through water to remove redundant salt and alkali so as to obtain soil with the pH of 6-7; generating organic fertilizers through microbial population by means of organic matters; detecting contents of nitrogen, phosphorus, potassium and other microelements required by crop growth in the soil; uniformly infiltrating quantitative organic fertilizers and controlled-release chemical fertilizers into soil according to the microelement contents of the soil and demands of the planted crops. According to the soil improvement method, raw materials for producing the fertilizers can be collected easily, and manufacturing cost is low. Capacity of municipal refuse treatment and reutilization is improved greatly, pollution is reduced, and the environment is beatified. The produced fertilizers can improve a land structure, kill malignant bacteria in the soil, decompose high-concentration chemical components in the soil and avoid soil hardening. In addition, yield increase of the crops is promoted, and crop quality is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to a soil modification method. Background technique [0002] Fertilizer production is very important to China's agricultural development. Chinese agriculture has used chemical fertilizers for many years. Generally speaking, chemical fertilizers mainly contain nitrogen, phosphorus, and potassium to supplement the lost nutrients for the soil, thereby increasing the total output of crops. However, in recent years, the utilization rate of chemical fertilizers has been declining, and the yield of crops is not as good as before. A number of agricultural studies have pointed out that although chemical fertilizers can add enough nutrients to the soil, they ignore the replenishment of organic matter. If chemical fertilizers are used alone for a long time, the soil will have adverse effects on soil quality and the environment. In the absence of sufficient organic matter in th...
