Problems solved by technology

[0003] At present, the improvement of saline-alkali soil usually uses salt washing, planting saline-alkali-tolerant crops, etc., which cannot fundamentally solve the problem
Soil improver is a means of improving saline-alkali soil in the prior art, but the improvement effect of the saline-alkali soil improver in the prior art is not ideal, and it cannot comprehensively improve the structure of the soil and increase the yield of crops
Therefore lack a kind of improver that can effectively improve saline-alkali soil, and can provide the nutrient substance needed for growth for crop to meet the demand of market

preparation example Construction

[0035] The present invention also provides the preparation method of the described saline-alkali soil conditioner, comprising the following steps:

[0036] (1) mixing animal manure, crop straw, rice husk and EM bacterial inoculum to obtain fermentation material, and stacking and fermenting the fermentation material for 20-30 d to obtain decomposed clinker;

[0037] (2) mixing the decomposed clinker with biochar, fly ash, humic acid, polypeptide amino acid, and ferrous sulfate, and granulating to obtain a saline-alkali soil conditioner.

[0038] In the present invention, the water content of the fermentation material during the stacking fermentation is 61-65%, preferably 63%; the central temperature of the fermentation stack during the stacking fermentation is 30-60°C, preferably 40-50°C, and further Preferably, the temperature is 45°C; the stacking fermentation time is preferably 25d; when the central temperature of the fermentation stack is >60°C, the stack is turned over imm...

Embodiment 1

[0048] Take 25kg of chicken manure, 25kg of duck manure, 40kg of soybean straw, 25kg of rice husk and 0.02kg of EM bacterial agent, and then pile and ferment for 25d under the condition of water content of 62% to obtain decomposed clinker. During the stacking fermentation, the core temperature of the fermentation pile should not exceed 60°C. Once it exceeds 60°C (including 60°C), the pile should be turned over immediately. The obtained decomposed clinker was mixed with 18kg of biochar, 10kg of fly ash, 10kg of humic acid, 2kg of polypeptide amino acid, and 3kg of ferrous sulfate in a granulator to obtain a soil conditioner for saline-alkali soil.

[0049] During the rotary tillage on April 18, 2020, the saline-alkali soil conditioner was applied in the amount of 1kg / mu, and the rice seedlings were transplanted on May 7 according to the plant-row spacing of 4cm. After transplanting, manage according to conventional methods. The pH, soil bulk density, and soil porosity of the s...

Embodiment 2

[0052] Take 60kg of chicken manure, 10kg of corn stalk, 20kg of peanut straw, 28kg of rice husk and 0.01kg of EM bacterial agent, and then pile and ferment for 20 days under the condition of water content of 65% to obtain decomposed clinker. During the stacking fermentation, the core temperature of the fermentation pile should not exceed 60°C. Once it exceeds 60°C (including 60°C), the pile should be turned over immediately. The obtained decomposed clinker was mixed with 15kg of biochar, 8kg of fly ash, 8kg of humic acid, 4kg of polypeptide amino acid, and 2kg of ferrous sulfate in a granulator to obtain a soil conditioner for saline-alkali soil.

[0053]During the rotary tillage on April 18, 2020, the saline-alkali soil conditioner was applied in the amount of 2 kg / mu, and the rice seedlings were transplanted on May 7 according to the plant-row spacing of 4 cm. After transplanting, manage according to conventional methods. The pH, soil bulk density, and soil porosity of the ...

Abstract

The invention relates to the technical field of agriculture, in particular to a saline-alkali soil conditioner and a preparation method and application thereof. The saline-alkali soil conditioner is prepared from the following components in parts by mass: 50 to 60 parts of animal waste, 30 to 40 parts of crop straw, 20 to 28 parts of rice husk, 12 to 18 parts of biochar, 8 to 12 parts of fly ash, 6 to 10 parts of humic acid, 2 to 6 parts of polypeptide amino acid, 2 to 4 parts of ferrous sulfate and 0.01 to 0.03 part of EM bacterium agent. The saline-alkali soil conditioner obtained according to the components can regulate the pH of soil, improve the soil structure and increase the crop yield.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a saline-alkali soil conditioner and a preparation method and application thereof. Background technique [0002] Saline-alkaline soil is a general term for saline soil and alkaline soil. Saline soil mainly refers to salinized soil with high chloride or sulfate content, the soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate. The pH value is high, the soil is alkaline, the organic matter content of the saline-alkali soil is low, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations that are harmful to crops. Promote seedlings. Plants can hardly survive in severe saline-alkali soil areas. [0003] At present, the improvement of saline-alkali soil usually adopts salt washing, planting salt-alkali-tolerant crops, etc., which cannot fundamen...
