Saline-alkali land soil improvement agent and preparation method thereof

Abstract

The invention belongs to the field of soil improvement and specifically relates to a saline-alkali land soil improvement agent and a preparation method thereof. The saline-alkali land soil improvementagent is obtained by mixing organic waste fermented materials, activated humic acid materials, chemical acidic fertilizer, ecological acidic fertilizer and starch uniformly. The organic waste fermented materials in the soil improvement agent contain various beneficial microorganisms and organic matters, can improve the physical structure of the soil and have the function of regulating and controlling a soil biota; gram-positive bacteria in the organic waste fermented materials can kill harmful bacteria, nematode in the soil and reduce soil-borne diseases; gangue, peat and lignite in the soilimprovement agent serve as associated mineral of coal production, contain a large amount of organic matters and rich trace elements, contain nutritional elements such as carbon, nitrogen, phosphorus and potassium necessary for crops, and achieves the effects of improving the physical and chemical properties and the biological properties of the soil, improving the soil fertility and increasing theyield of the crops in the soil improvement agent.

Description

technical field [0001] The invention belongs to the field of soil improvement, and in particular relates to a saline-alkaline soil improvement agent and a preparation method thereof. Background technique [0002] Land salinization is one of the main hazards that cause the decline of land production capacity and land loss. Controlling salinization and improving soil are issues of concern to the entire agriculture, forestry, animal husbandry, and water industries. Xinjiang is a region with serious saline-alkali land hazards in my country. There are about 1,333,300 hectares of saline-alkali cultivated land, and nearly 1 / 3 of the cultivated land is saline-alkali, of which more than 80% are secondary soil salinization. Except for the milder soil salinization in the Ili Valley, the Altay region, and some areas in Tacheng, the soil salinization in other areas has varying degrees, and the southern foot of the Tianshan Mountains and the irrigation areas in the west of the Tarim Basin...
