Saline and alkaline soil improvement agent including soil loosening agent, and preparation method of soil improvement agent

Abstract

The invention discloses a saline and alkaline soil improvement agent including a soil loosening agent. The saline and alkaline soil improvement agent comprises 120-180 parts of the soil loosening agent, 250-400 parts of a soil improving organic fertilizer, 160-200 parts of rhamnolipid, 120-160 parts of a blue alga decomposition accelerator, 80-120 parts of hydroxyethyl cellulose, 30-60 parts of potassium dihydrogen phosphate, 8-20 parts of potassium dihydrogen phosphate, 800-1200 parts of water and 10-14 parts of a microbial fermentation agent. The saline and alkaline soil improvement agent including the soil loosening agent improves the soil structure, increases the air permeability of soil and supplements organic matters; and the saline and alkaline soil improvement agent can be combined with common chemical improvements in the prior art to realize ion change of sodium ions in oil in order to reduce alkalis and remove salts, so the saline and alkaline soil is thoroughly improved without replacing soil, and the saline and alkaline soil improvement agent can be used in agricultural production.

Description

technical field [0001] The invention relates to a saline-alkaline soil improvement agent containing a soil bulking agent and a preparation method thereof. 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 eas...

Problems solved by technology

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 nitrogen, phosphorus, and potassium major elements, as well as trace elements such as iron, calcium, and boron.

[0003] At present, most of the fertilizers used in saline-alkali land are ordinary fertilizers. Although ordinary fertilizers can provide some nutrients for the soil, they cannot effectively increase the air permeability of the soil while reducing the soil salinity, soil pH, and soil bulk density. Soil water retention capacity, increase the microbial content in the soil, and comprehensively improve soil fertility
