Problems solved by technology

[0002] Currently, changing the farming system, improving fertilization methods, and using soil conditioners are the main restoration methods in the restoration of obstacle soil. These restoration methods can only improve the obstacle soil to a limited extent, but cannot restore the damaged microbial community in the obstacle soil. Larger, and the repair effect is poor
There is also a technical method of using bio-organic fertilizers to repair the barrier soil, but this type of bio-organic fertilizers are microorganisms with specific functions, the resulting products have limited functions, and it is difficult to obtain microorganisms

Abstract

The invention discloses a soil conditioner, which is prepared from the following components in parts by weight: 10-20 parts of distiller grains, 1-10 parts of cow dung, 1-10 parts of earthworm cast, 1-10 parts of oil cake, 10-20 parts of decoction dregs, 20-40 parts of fallow soil and 20-40 parts of river sands. The invention further discloses a method for preparing the soil conditioner, which comprises the following steps: firstly, respectively fermenting the distiller grains, cow dung, earthworm cast, oil cake and decoction dregs; and then, mixing with river sands and fallow soil, and performing secondary solid fermenting culture to obtain the soil conditioner. The soil conditioner has a remarkable effect for repairing barrier soil, and enables the microbial diversity index of repaired soil to be improved and the soil microbial ecological structure to be improved, so that the crop quality can be promoted.

technical field [0001] The invention relates to a soil conditioner and a preparation method thereof, belonging to the technical field of soil ecological restoration. Background technique [0002] Currently, changing the farming system, improving fertilization methods, and using soil conditioners are the main restoration methods in the restoration of obstacle soil. These restoration methods can only improve the obstacle soil to a limited extent, but cannot restore the damaged microbial community in the obstacle soil. The sexiness is bigger, and the restoration effect is poorer. There is also a technical method of using bio-organic fertilizers to repair the barrier soil, but this type of bio-organic fertilizers are microorganisms with specific functions, the resulting products have limited functions, and it is difficult to obtain microorganisms. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the p...
