Abstract

The invention relates to the technical field of soil improving materials, in particular to a soil conditioner. The conditioner is mainly prepared from mineral materials, an activating agent A, a microbial agent, an activating agent B used for providing nutrition for the microbial agent, and an enzymic preparation. The mineral materials include zeolite, attapulgite and sepiolite. The main component of the activating agent A is organic acid. A bacterial strain contained in the microbial agent is bacillus subtilis.

Description

technical field [0001] The invention relates to the technical field of soil improvement materials, in particular to a soil conditioner. Background technique [0002] Soil Conditioner has the functions of improving soil, controlling deserts, water retention and drought resistance, enhancing crop resistance, increasing crop yield, improving the quality of agricultural products, restoring the original ecology of crops, etc. Improve the quality of agricultural and forestry products and restore the natural appearance of agricultural and forestry products. [0003] At present, my country's saline-alkali soil accounts for about one tenth of the world's total, and about 20% of irrigated agricultural land is affected by salinization, of which arid and semi-arid saline-alkali soil accounts for 54%, which has become the biggest environmental problem in dryland agriculture. Therefore, actively researching and exploring the control measures of soil salinization, improving the effective ...
