Ecological soil conditioner for improving saline and alkaline land soil and preparation method

Abstract

The invention belongs to the technical field of soil improvement and particularly relates to an ecological soil conditioner for improving saline and alkaline land soil and a preparation method. The ecological soil conditioner is prepared from, by weight, 30-80 parts of industrial residues, 20-40 parts of sulfonated humic acid, 10-20 parts of pyroligneous solution, 10-30 parts of nano-filler, 5-15 parts of pH-sensitive hydrogel, 1-5 parts of water-soluble starch, 1-5 parts of cyclodextrin, 1-5 parts of medium trace elements and 0.5-3 parts of traditional Chinese medicine extract. The soil conditioner is environmentally friendly and safe, the application method is simple and easy to implement, the soil conditioner can be applied along with fertilizer in a drip irrigation mode, the utilization rate of the fertilizer is increased, nutrient elements can be released along with pH changes of the soil environment, a certain slow release effect is achieved, the utilization rate of the soil conditioner is greatly increased, cost is greatly reduced, meanwhile, the status quo of the saline and alkaline land soil can be improved, the organic matter content of the soil can be increased, and diseases and pests of the soil can be reduced.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to an ecological soil conditioner for improving saline-alkali soil and a preparation method thereof. Background technique [0002] my country is a big country with saline-alkali land, and the national saline-alkali farmland soil area accounts for about 60% of the country's land area. Due to the high salinity and high alkalinity in the saline-alkali soil, the soil is sticky and heavy, the organic matter in the soil is destroyed and lost, the air permeability is poor, it swells and becomes muddy when it encounters water, and it shrinks hard when it loses water, which seriously affects the germination of crop seeds and the normal development of crops. In addition, Excessive sodium ions in the soil are alkaline, directly destroying plant tissue, and the root system of crops is also perishable, affecting nutrient transformation, making phosphorus fertilizer and trace...

Problems solved by technology

[0008] In order to solve the deficiency in improving the function of saline-alkali soil, the present invention proposes an ecological soil conditioner and a preparation method for improving saline-alkali soil. The ecological soil conditioner is environmentally friendly and safe, and is a slow-dissolving particle with certain water solubility. The method of use is simple and easy, and it can be drip-irrigated with fertilizers to improve the utilization rate of fertilizers, especially nitrogen and phosphorus fertilizers and medium and trace element fertilizers; and it will release nutrients with the pH changes of the soil environment, which has a certain slow-release effect and greatly Improve the utilization rate of soil conditioner, greatly reduce the cost, and at the same time improve the status of soil in saline-alkali soil, increase the content of soil organic matter, improve the phenomenon of soil compaction in saline-alkali land, reduce the occurrence of soil diseases and insect pests, and improve the absorption of phosphorus fertilizer and trace element fertilizer by soil
