Problems solved by technology

It can be said that the saline-alkali soil microbial improver prepared by fermenting traditional Chinese medicine dregs with microorganisms has broad application prospects in the treatment of saline-alkali land. At present, there is no special preparation system for saline-alkali soil microbial improver. Due to the preparation process of the improver, There are strict requirements on the water content of traditional Chinese medicine dregs, usually in the range of 15-25%, and it is difficult for existing equipment to obtain quantitatively the water content of traditional Chinese medicine dregs through pressure filtration; at the same time, due to the long fermentation period during the fermentation process, Changes in the external ambient temperature will also have adverse effects on the fermented products in the fermenter, and it is difficult to ensure that the fermentation temperature is constant within a controllable range; in addition, the preparation method is still mostly in the theoretical exploration

Abstract

The invention relates to a preparation system and method of a saline-alkali soil microbial improver. The preparation system mainly comprises a filter pressing subsystem, a fermentation subsystem and adrying subsystem, the filter pressing subsystem is used for carrying out filter pressing on the traditional Chinese medicine residue substrate to obtain a substrate with required water content; the fermentation subsystem is used for mixing and stirring the traditional Chinese medicine residue substrate subjected to filter pressing, a microbial agent and sucrose water, and performing fermenting; and the drying subsystem is used for baking the fermented material to obtain a solid composite fermented material, and the composite fermented material can be used for improving saline-alkali soil after being crushed. According to the invention, the water content can be controlled in the filter pressing process, and a long-period and stable fermentation environment can be provided in the fermentation process.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement, in particular to a preparation system and method of a saline-alkali land soil microbial amendment. Background technique [0002] At present, traditional Chinese medicine products are widely used. After the traditional Chinese medicine factory prepares the liquid medicine, the remaining Chinese medicine dregs are directly buried or incinerated, causing a lot of waste. However, there are a large number of saline-alkali lands in the northwest and coastal areas of our country. Due to the lack of organic matter in the soil, crops are not suitable for planting, resulting in a large amount of land being abandoned. Now the scientific community is exploring the recycling of traditional Chinese medicine dregs, and making saline-alkali soil conditioner through microbial fermentation, which is used to improve saline-alkali soil. It can be said that the saline-alkali soil microbial imp...
