Abstract

The invention belongs to the technical field of agricultural fertilizers and relates to a soil improvement agent and a preparation method thereof. The soil improvement agent comprises the following raw materials in part by weight: 1-10 parts of fish aquatic products processing waste powder, 10-20 parts of shell powder, 1-10 parts of straw powder, 1-10 parts of diatomite, 0.1-2 parts of high-activity biological agent, 2-5 parts of acid and 1-10 parts of medical stone powder. The preparation method comprises the steps as follows: adding the raw materials into a mixer and mixing fully and uniformly to obtain the soil improvement agent. The soil improvement agent is used for improving saline alkali soil, so that the soil salinity can be reduced, the volume weight of soil can be reduced, the soil porosity can be enhanced, the soil permeability can be enhanced, the soil pH value can be reduced, the soil organic matter can be increased, and the soil fertility can be enhanced.

Description

technical field

[0001] The invention belongs to the technical field of agricultural fertilizers, and relates to a soil improver and a preparation method thereof. The soil improver is mainly used for improving saline-alkali soil. Background technique

[0002] The Yellow River Delta is one of the three major estuary deltas in my country and has great potential for land development and utilization. However, this area is close to the Bohai Sea, and saline-alkali land is widely distributed, with an area of ​​442,900 hm of salinized land 2 , accounting for more than half of the total area of ​​the whole region, among which, 236,300 hm of heavily salinized soil and saline-alkali bare ground 2 , accounting for about 28.4% of the area's land area. The soil has high salinity, mainly chloride, and the salinity of the soil surface is in the range of 0.4% to 3%. The soil structure is poor, and the fertility is low. Without improvement and treatment, it is difficult to carry out agricul...
