Saline-alkali land biomass soil conditioner

Abstract

The invention discloses a saline-alkali land biomass soil conditioner. The saline-alkali land biomass soil conditioner is prepared from plant ash, straws, sheep manure, an organic fertilizer, a phosphate fertilizer, a nitrogen fertilizer, sulfur and a microbial improving bactericide. A production method comprises the steps: firstly, smashing the plant ash, the straws, the sheep manure, the organicfertilizer, the phosphate fertilizer, the nitrogen fertilizer and sulfur and evenly stirring; then spraying the microbial improving bactericide; mixing and fermenting to be used. According to the saline-alkali land biomass soil conditioner, product raw materials are drawn on local resources, the resources are abundant, and a production technology is simple and easy to operate; the soil conditioner product prepared from biomass has the advantages lower cost, no pollution and fertilizer efficiency; the soil conditioner is prepared from naturally existing organisms (or matters) in soil, does notcontain pollutants of chemicals, heavy metal and the like, has no pollution to soil environment and green plants and has an obvious soil improving effect; furthermore, soil is prevented from hardening.

Description

technical field [0001] The invention relates to the field of soil improvement, in particular to a saline-alkali land biomass soil improver. Background technique [0002] Soil salinization has become one of the main reasons restricting the development of agriculture and animal husbandry in arid areas of our country. Saline-alkali land is the most important reserve land resource in China. Improving and utilizing saline-alkali land can increase the area of ​​cultivated land and alleviate the conflict between man and land. Especially with the current situation that the pressure of insufficient land resources in our country is increasing year by year, it is very important to carry out the improvement, restoration and continuous utilization of saline-alkali land, especially in arid and semi-arid areas, land salinization is a problem that needs to be paid attention to and solved. In order to achieve the sustainable development of agriculture and achieve the goal of high yield, hig...

Problems solved by technology

[0003] At present, there are many types of solid particle modifiers developed using materials such as dolomite, phosphogypsum, phosphate rock powder, zeolite, montmorillonite powder, calcium silicate powder, sulfur powder, limestone powder, boron ore powder, etc., but mineral modifiers Use sometimes breaks the balance of soil chemical elements. Too much of a certain nutrient will affect plant growth, cause soil heavy metal pollution, and easily cause negative effects such as soil compaction in low soil moisture or dry seasons.
