Conditioning agent of high-nutrient saline soil and preparation method and application thereof

Abstract

The invention discloses a conditioning agent of high-nutrient saline soil and a preparation method and application thereof. The conditioning agent is prepared from charcoal, non-ionic polyacrylamide, anionic polyacrylamide, cationic polyacrylamide, lignite and kieselguhr according to the mass ratio of (5 to 10):(2 to 4):(2 to 4):(1 to 3):(3 to 5):1. The conditioning agent provided by the invention solves a series of problems of poor soil physical property, high ion content, low soil quality and the like caused by the saline phenomenon on the soil; the soil volume weight is reduced; the soil porosity degree is increased; the exchange of water, gas, heat and the like in the soil can be facilitated; the soil fertility is improved; meanwhile, the salt ion content and the whole salt content are reduced; the harm to the soil and the crops is reduced, so that the crop yield is increased.

Description

Technical field [0001] The invention relates to a polymer conditioner and a preparation method and application thereof, in particular to a conditioner for high-nutrient saline soil, and a preparation method and application thereof. Background technique [0002] Salinized soil contains potassium, sodium, calcium, magnesium chloride, sulfate, bicarbonate and other saline-alkali components, which will cause abnormal soil physical and chemical properties, low soil quality, and inhibit plant growth to varying degrees. The salinization of the soil in the greenhouse is due to the rapid growth of facility planting, high yield, and a large number of crops. The park often applies a large amount of base fertilizer (mainly organic fertilizer) before each crop. Therefore, some nutrients are not absorbed by the crops. And fertilizers remain in the soil in large quantities and become the main source of soil salt segregants, making the soil's nitrate nitrogen, phosphorus, potassium, and sulfate ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a conditioner for high nutrient salinization soil, the conditioner of the present invention solves a series of problems such as poor soil physical properties, high ion content and low soil quality caused by salinization phenomenon , can reduce soil bulk density and increase soil porosity, which is conducive to the exchange of water, air, heat, etc. in the soil to improve soil fertility, and at the same time reduce the content of salt ions and total salt, and reduce its harm to soil and crops , thereby increasing the crop yield
