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.

[0018] In organic fertilizer: humic acid 10%, mineral fulvic acid 1%, amino acid 1%, bagasse 25%, biochar 33%, calcium sulfate 30%;

[0019] Inorganic fertilizers are purchased from the market. The content of nitrogen, phosphorus and potassium in inorganic fertilizers is: nitrogen ≥ 20%, phosphorus ≥ 15%, and potassium ≥ 10%.

[0020] The organic fertilizer is prepared by uniformly mixing all raw materials and fermenting them by conventional methods in the prior art.

[0021] Microbial agent Microbial agent is made by adding microorganisms to decomposed straw. The microbial agent contains: Bacillus subtilis 100 million cfu / g, Bacillus megaterium 100 million cfu / g, halophilic bacteria 100 million cfu / g, yeast Bacteria 100 million cfu / g. ...

Embodiment 2

[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.

[0030] In organic fertilizer: humic acid 12%, mineral source fulvic acid 1.5%, amino acid 1.5%, bagasse 20%, biochar 35%, calcium sulfate 30%;

[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.

[0034] In organic fertilizer: humic acid 13%, mineral fulvic acid 2%, amino acid 2%, bagasse 22%, biochar 33%, calcium sulfate 28%;

[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.

Abstract

The invention discloses a soda saline soil comprehensive fertilization conditioner and a soil improvement method thereof. The conditioner comprises an inorganic fertilizer, an organic fertilizer, a microbial agent and decomposed straw which are matched for use; the inorganic fertilizer comprises nitrate nitrogen, monopotassium phosphate, humic acid, mineral fulvic acid, amino acid, bagasse, charcoal and calcium sulfate; and the microbial agent comprises bacillus subtilis, bacillus megatherium, halophilic and halophilic bacteria and saccharomycetes. The invention provides a comprehensive fertilization conditioning and improving technology aiming at the three problems of thin, dead and thick saline-alkali soil, and the conditioner can obviously enhance the ion exchange capacity of soil, increase the content of available nutrients and slow-release nutrients of the soil, increase the air permeability of the soil, reduce the pH value of the soil, activate the microbial activity of the soil and improve the drought resistance of the soil and crops; and the conditioner disclosed by the invention is a multifunctional saline soil improvement fertilizer with balanced nutrients, can continuously improve soil and improve soil fertility, and realizes yield increase and efficiency increase of agricultural products.

Description

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 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. 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...
