A kind of mineral microbial soil conditioner suitable for saline-alkali land and preparation method thereof

Abstract

The invention provides a mineral microbial soil conditioner suitable for saline-alkali land. The soil conditioner contains 40-50% of limestone, 10-20% of shale, 10-30% of humic acid, and Bacillus subtilis by weight percentage. Bacillus 1‑3%, Mallow 1‑5%, Akebia 1‑5%, Psyllium 1‑5%, and Eupatorium 1‑5%. The invention takes the ecological balance as the criterion, and according to the properties of the soil, organically synthesizes the minerals and microorganisms in a targeted manner, and activates each other to generate reactions under certain conditions to change the soil structure. The conditioning agent of the present invention is mainly used for saline-alkali land transformation to solve the problem of land desertification.

Description

technical field [0001] The invention relates to a soil conditioner, specifically a mineral microbial soil conditioner, and also relates to its preparation method and application. Background technique [0002] The situation of desertification in China is very serious. According to the materials released by the State Forestry Administration Office of Desertification Control and other government departments in 1998, China is one of the countries with severe desertification in the world. According to the national desert, Gobi and sandy land census and desertification survey results, China's desertified land area is 2.622 million square kilometers, accounting for 27.4% of the country's land area, and nearly 400 million people are affected by desertification. According to the research of international cooperation projects between China, the United States and Canada, the direct economic loss caused by desertification in China is about 54.1 billion RMB. [0003] At present, the tot...
