Saline-alkaline soil amendment

Abstract

The invention discloses a saline-alkaline soil amendment, relates to a soil fertilizer conditioner, and belongs to the soil fertilizer field. The saline-alkaline soil amendment is characterized in that raw materials comprise, by weight, 10-30% of beneficial microorganism, 5-30% of gypsum, 5-20% of charcoal, 10-20% of pyroligneous liquor, 10-20% of 732 type cation exchange adsorption resin (H+ type), and 10-40% of organic polymer. The beneficial effects of the saline-alkaline soil amendment are that: by employing the amendment, soil is improved, soil fertility is improved, crop growth is promoted, soil ecology balance is maintained, crop pollution is reduced, and an effective way is provided for soil sustainable utilization, the way is novel, safe, reliable and stable for soil-borne disease prevention, and the way plays an important role in achieving pollution-free sustainable development for green food, the amendment promotes the popularization and application of soil amendment technology, land salinization is reduced, and toxic effects of saline-alkali soil on seeds are alleviated.

Description

technical field [0001] The invention relates to a soil fertilizer conditioner, which belongs to the field of soil fertilizer, in particular to a saline-alkali soil conditioner. Background technique [0002] Soil conditioners, also known as soil conditioners, are materials that are mainly used to improve the physical, chemical and biological properties of soil to make them more suitable for plant growth, rather than mainly providing plant nutrients. agent. For example, lime is used to adjust the pH value of acidic soil, and gypsum is used to suppress Na in the soil. + , HCO 3- , and CO 3 2- Plasma, application of beneficial microorganisms to enhance soil biological activity, etc. [0003] my country is a big country with saline-alkali land, how to improve saline-alkali land has always been a research hotspot. There are complex microbial flora systems in the soil environment. The long-term natural environment has made these flora a relatively stable micro-ecological flor...

AI Technical Summary

Problems solved by technology

[0004] Due to the special geographical and climatic environment, the accumulation of salt in the soil, and the influence of the agricultural farming system, the micro-ecological flora of the soil is destroyed, especially the physical and chemical properties and biological properties of the soil are destroyed by continuous cropping, so that the soil is compacted, the nutrients are destroyed, The imbalance of microbial flora hinders the normal transportation of water, air, and nutrients. It is difficult for beneficial microorganisms to survive, and it is difficult for ordinary plants that are not resistant to salt and alkali to survive, resulting in a continuous cycle of nausea and even more serious salinization.
