Problems solved by technology

[0002] The physical and chemical properties of saline-alkali soil are poor, with less organic mass, less soil humus, damaged soil structure, sticky when wet, hard when dry, poor ventilation and water permeability, and the increase of soil-borne disease sources and pests in the soil, resulting in wilting and poisoning of plants And rotten roots die, and the soil is too alkaline, which affects the availability of nutrients in the soil, easily causes the loss of a large number of elements, and greatly affects the growth of plants
The use of river pond silt to prepare organic fertilizers can effectively reduce the alkalinity of the soil, increase the nutrient content of the saline-alkali soil, improve the characteristics of the saline-alkali soil, and benefit the improvement of the saline-alkali soil. Insufficient bacterial flora in organic fertilizers, less organic quality and soil humus quality, less improvement to saline-alkali soil, not conducive to saline-alkali soil improvement

Embodiment 1

[0014] The method for preparing saline-alkali improved fertilizer by using river pond silt comprises the steps of:

[0015] (1) concentrating river pond silt to make its water content reach 30%;

[0016] (2) Cut the fresh straw into 0.5cm straw sections, mix the concentrated river pond silt, fresh livestock and poultry manure and straw sections at a weight ratio of 50:10:20, put them into a container, seal them and pass in steam. , pressure to 2.0MPa, reaction time is 10 hours;

[0017] (3) After the reaction, the mixture is lowered to normal temperature, and adjusted to a water content of 10%, then pulverized, and then mixed with a compound microbial agent according to 5% of the weight of the mixture after the reaction. ;

[0018] Wherein the composite bacterial agent is 2 parts of yeast, 1.5 parts of Bacillus subtilis, 1 part of Bacillus megaterium, 0.5 part of Trichoderma viride, 0.6 part of potassium bacteria, 0.5 part of nitrogen-fixing bacteria and 0.1 part of white ro...

Abstract

The invention discloses a method for preparing a saline-alkali soil improvement fertilizer by utilizing river and pond silt, which comprises the following steps: after being concentrated, river and pond silt is fermented and sterilized along with fresh livestock and poultry feces and straws under high temperature and high pressure, and after the mixture is mixed with compound bacterial agent to ferment, the improvement fertilizer is prepared. The processing method disclosed by the invention is mature, the acting effect of flora in the prepared organic fertilizer is high, the amount of organicmatters and the amount of soil humus are large, the improvement of saline-alkali soil is greater, and the improvement of saline-alkali soil is benefited.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a method for preparing saline-alkali-improved fertilizers by utilizing river and pond silt. Background technique [0002] The physical and chemical properties of saline-alkali soil are poor, with less organic mass, less soil humus, damaged soil structure, sticky when wet, hard when dry, poor ventilation and water permeability, and the increase of soil-borne disease sources and pests in the soil, resulting in wilting and poisoning of plants In addition, the soil is too alkaline, which affects the availability of nutrients in the soil, and easily causes the loss of a large number of elements, which has a great impact on the growth of plants. The use of river pond silt to prepare organic fertilizers can effectively reduce the alkalinity of the soil, increase the nutrient content of the saline-alkali soil, improve the characteristics of the saline-alkali soil, and benefit...
