Abstract

The invention belongs to the field of soil improvement, and particularly relates to a soil leavening agent, which is prepared from the following raw materials in parts by mass: 25 to 28 parts of crushed corn straws, 25 to 28 parts of crushed cotton straws, 20 to 22 parts of edible fungus dregs, 5 to 10 parts of turfy soil, 5 to 8 parts of plant ash and 5 to 8 parts of zeolite powder. The oil leavening agent provided by the invention can improve a soil structure, increase soil aeration and supplement organic matter; by being combined with a chemical modifier commonly used in the prior art, the effect of reducing alkaline and desalting can be realized by ion exchange of sodium ions in the soil, and on the premise of not changing the soil, the saline-alkali soil can be thoroughly modified and can be further used for agricultural production or urban landscaping.

Description

technical field [0001] The invention belongs to the field of soil improvement, in particular to a soil bulking agent. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. Soil salinization is a worldwide problem. The saline-alkali soil area in the world is about 1 billion hectares. my country has 99.13 million hectares, or about 1.47 billion mu. More than 100 cities in the country are located in saline-alkali soil distribution areas. Nearly 500 million mu of land has been reduced or abandoned due to salinization, mainly concentrated in the arid and semi-arid regions of North China, Northwest China and Northeast China. In addition, during the cultivation process, the long-term excessive application of chemical fertilizers leads to the intensification of secondary salinization of the soil, serious compaction, and the continuous expansion of salinized and alkalized so...
