Problems solved by technology
[0002] There are three problems in saline-alkali land: "thin, dead, and hard". The nutrient content in the soil is low, the soil aggregate structure is damaged, the ventilation performance is poor, and the soil is compacted, resulting in low microbial activity in the soil, and reduced crop emergence rate and yield.
The currently promoted saline-alkali soil improvers, such as calcium sulfate and aluminum sulfate, mainly exchange sodium ions from the saline-alkali soil out of the soil, and do not have the effect of improving soil and improving soil fertility.

Embodiment 1
[0017] A comprehensive fertilization conditioner for soda saline soil, comprising the following raw materials used together: 10 kg of inorganic fertilizer, 20 kg of organic fertilizer, 2 kg of microbial agent, and 500 kg of decomposed straw.
[0029] This example is roughly the same as Example 1, except that the comprehensive fertilization conditioner for soda saline soil includes: 13kg of inorganic fertilizer, 23kg of organic fertilizer, 3kg of microbial agent, and 580kg of decomposed straw.
[0031] Among them, the dosage of inorganic fertilizer is 13kg per mu; the dosage of organic fertilizer is 23kg per mu; the dosage of microbial agent is 3kg per mu; the dosage of decomposed straw is 580kg per mu.
Embodiment 3
[0033] This example is roughly the same as Example 1, except that the comprehensive fertilization conditioner for soda saline soil includes: 15kg of inorganic fertilizer, 25kg of organic fertilizer, 5kg of microbial agent, and 650kg of decomposed straw.
[0035] Among them, the dosage of inorganic fertilizer is 15kg per mu; the dosage of organic fertilizer is 25kg per mu; the dosage of microbial agent is 5kg per mu; the dosage of decomposed straw is 650kg per mu.

technical field [0001] The invention relates to the technical field of soda saline soil control, in particular to a soda saline soil comprehensive fertilization conditioner and a method for improving soil. Background technique [0002] There are three problems in saline-alkali land: "thin, dead, and hard". The nutrient content in the soil is low, the soil aggregate structure is damaged, the aeration performance is poor, and the soil is compacted, resulting in low microbial activity in the soil, and reduced crop emergence rate and yield. The currently promoted saline-alkali soil improvers, such as calciumsulfate and aluminum sulfate, mainly exchange sodium ions from the saline-alkali soil out of the soil, and do not have the effect of improving soil and improving soil fertility. Therefore, it is necessary to develop a conditioner that can both reduce saline-alkali components in saline-alkali soil and improve soil fertility. Contents of the invention [0003] The purpose o...
