Abstract

The invention discloses a mineral-substance saline-and-alkaline-land soil modifying agent. The mineral-substance saline-and-alkaline-land soil modifying agent is prepared from, by mass, 120-180 parts of shale, 250-400 parts of citric acid residues, 160-200 parts of a releasing bonding agent, 120-160 parts of malva seeds, 80-120 parts of calcite powder, 30-60 parts of phytase, 8-20 parts of gold stone powder, 800-1,200 parts of palygorskite powder and 10-14 parts of microelement fertilizer. According to the mineral-substance saline-and-alkaline-land soil modifying agent, all nutrient ingredients are reasonably matched, all the ingredients are combined, influenced and coordinated each other, and soil secondary salinization caused by fertilizer abusing can be avoided.

Description

technical field [0001] The invention relates to a mineral saline-alkali soil improver and its preparation and application. Background technique [0002] Soil salinization has a relatively large damage to the physical and chemical properties of the soil, which is extremely unfavorable to the growth of many crops, and it is easy to cause the lack of seedlings or death of crops, thus hindering the development of agricultural economy. Due to the high salt content, low organic mass, and high pH in saline-alkali land, the soil humus is leached and the soil structure is damaged. It is sticky when wet and hard when dry. There are often white salt deposits on the soil surface, and poor ventilation and water permeability. Severe cases can cause plant wilting, poisoning and root rot to die. In addition, if the soil is too alkaline, it will affect the availability of nutrients such as phosphorus, iron, manganese, boron, and zinc in the soil, and will easily cause a large amount of nitr...
