Abstract

The invention relates to a method for improving Suda saline-alkali soil and generating a biochemical fulvic acid raw material, which belongs to the field of natural resources and ecological environment. The method comprises the following steps of preparing steam expanded straws, preparing a biochemical fulvic acid raw material, carrying out multistage salt leaching on saline-alkali soil, and preparing a biochemical sodium fulvate raw material. The method has the advantages that the purpose of improving the saline-alkali soil by agricultural wastes is achieved, and compared with the conventional method, the generated biochemical fulvic acid raw material has the advantages of shortened fermentation time, high humic acid content, trace elements and organic matters. The soil salinity is reduced, the excessive sodium ions are removed and fixed, the optimal pH value range is regulated, the soil aggregate structure beneficial for the target plant growth is formed, and the method is used in the fields of straw resource utilization, biochemical fulvic acid raw material production, saline-alkali soil modifier production, saline-alkali soil improvement technology, sodium fulvic acid raw material production, engineering strain fertilizer production and the like; the method is economical, environment-friendly, renewable in resource, beneficial to sustainable development of agriculture, universal in applicability and easy to popularize.

Description

technical field [0001] The invention relates to the fields of natural resources and ecological environment, in particular to a method for improving Suda saline-alkali land and generating biochemical fulvic acid raw materials. Background technique [0002] my country is rich in straw resources, ranking first in the world, among which the annual output of corn straw reaches more than 24 million tons, accounting for 24.00% of the total straw production in the country, but only 27.13% for feeding. At present, there are many ways to utilize straw in our country, such as using fuel, or direct waste incineration; mechanical returning to the field; processing silage and pellet feed; cultivating edible fungi; processing handicrafts; processing building boards; gasification; Fertilizer processing; Preparation of fuel alcohol; Direct combustion power generation. However, most of the straw is used as living fuel or burned on the spot, which not only causes waste of resources, but also ...
