Problems solved by technology

The application number is 201010601152.9, which discloses a method for improving soda alkalized soil with an inorganic polymer soil improver. The inorganic polymer soil improver is solid polyferric sulfate, and its principle is to replace sodium ions in saline-alkali land. It is the reaction product sodium sulfate that needs to be washed continuously for medium and severe saline-alkali land, and it is easy to return to saline-alkali
However, the price of solid polyferric sulfate modifier is more expensive, and the improvement cost is higher
Extensive use of aluminum sulfate amendments leads to a rapid increase in soil soluble aluminum content, which is likely to cause aluminum ion poisoning to rice

Abstract

The invention discloses a soda saline-alkaline land paddy field soil modifier and a preparation method thereof. Granules and microbial agents are mixed to react to obtain the modifier, and the granules comprise blocking agents, acid regulators, organic fertilizers and sedimentation agents. The soda saline-alkaline land paddy field soil modifier is applicable to improvement of soda saline-alkalineland paddy field soil, natural quasi-nano-nonmetallic mineral media are selected, automatically separate water and soil, naturally subside in a plowing layer of a saline-alkaline land and finally forman inert saline-alkaline isolate interface in a plow pan, halophilic alkali-resistant microbial agents are applied into the soil, various molecular mechanisms of the microbial agents such as acid discharging and neutralization, in-vivo enrichment salt inert treatment and degradation of organic matter by secreted extracellular enzymes in the plowing layer are utilized, so that soil saline and alkali degree is reduced, microbial activity of the soil is activated, an aggregated structure of the soil is improved, and the saline-alkaline land is fundamentally controlled.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a paddy field soil conditioner for soda saline-alkali land and a preparation method thereof. Background technique [0002] Physical measures are generally taken to control saline-alkali paddy fields, mainly in the following two ways: one is based on the law of water and salt operation of "salt comes with water, salt goes with water", and digs drainage ditches for low-lying areas , can draw out the excess water accumulated in the area and discharge it to other places, but this method is easy to return to saline; or, introduce external water into the area to form an aquifer at a certain depth in the depression, and soak for a long enough time to As for the salt contained in the soil fully dissolved in the water, it is discharged to the outside of the depression, and the salt in the soil is taken away with the water, thereby reducing the salt content of the soil...
