Problems solved by technology

[0003] However, the traditional method of soil improvement in saline-alkali land mainly uses desulfurized gypsum or phosphogypsum to replace sodium in the soil. This method is relatively simple, and it is easy to increase the salinity of the soil, resulting in an increase in soil bulk density; in addition, more irrigation is required. Drainage can reduce the total salt content of the soil and increase the risk of soil compaction

Embodiment 1

[0021] Get the corn stalk that percentage by weight is 30%, pulverizes with pulverizer earlier, then with 50% chicken manure, 10% phosphate rock powder, 5% gypsum, 2% ammonium sulfate and 3% bacterium agent (bacteria agent It is obtained by mixing Bacillus megaterium, Bacillus subtilis, Trichoderma viride and lignocellulosic bacteria in any proportion) after stirring and mixing evenly, fermenting under natural conditions for 50 days, drying in a dryer, and then sifting through a mesh, bagging and sealing That's it.

Embodiment 2

[0023] Get the corn stalk that percentage by weight is 20%, pulverizes with pulverizer earlier, then with 60% pig manure, 10% phosphate rock powder, 5% gypsum, 3% ammonium sulfate and 2% bacterial agent (bacterial agent It is obtained by mixing Bacillus megaterium, Bacillus subtilis, Trichoderma viride and lignocellulosic bacteria in any proportion) after stirring and mixing evenly, fermenting under natural conditions for 50 days, drying in a dryer, and then sifting through a mesh, bagging and sealing That's it.

Embodiment 3

[0025] Get the wheat straw that weight percent is 10%, pulverize with pulverizer earlier, then with 70% cow dung, 10% calcium superphosphate, 5% gypsum, 4% ammonium sulfate and 1% bacterial agent (microbial agent It is obtained by mixing Bacillus megaterium, Bacillus subtilis, Trichoderma viride and lignocellulosic bacteria in any proportion) after stirring and mixing evenly, fermenting under natural conditions for 50 days, drying in a dryer, and then sifting through a mesh, bagging and sealing That's it.

Abstract

The invention provides an organotrophic saline soil conditioner. The conditioner is prepared from the following components in percentage by weight: 50%-70% of livestock and poultry wastes, 1%-5% of accelerator, 10%-30% of straw, 8%-15% of powdered rock phosphate or calcium superphosphate, 3%-8% of gypsum and 1%-8% of modifier. When the soil conditioner is applied in the saline alkali soil, the volume weight of the soil can be reduced, the porosity is increased, the velocity of permeability is improved, the water retention capacity is enhanced, the pH value is significantly reduced and the structure of the soil is greatly improved. The application of the soil conditioner promotes the improvement in phosphorus and nitrogen levels and thus the yields of crops are further increased.

Description

technical field [0001] The invention belongs to the technical field of soil conditioners, and in particular relates to an organic nutrition saline soil conditioner. Background technique [0002] With the wide application of soil conditioners in agriculture and ecological environment, there are more and more new products of soil conditioners at home and abroad. Especially in recent years, the emergence of high-efficiency and low-consumption soil improvers or conditioners, the continuous improvement of use methods and the gradual reduction of costs have made it possible for soil improvers to be widely used in the field. [0003] However, the traditional method of soil improvement in saline-alkali land mainly uses desulfurized gypsum or phosphogypsum to replace sodium in the soil. This method is relatively simple, and it is easy to increase the salinity of the soil, resulting in an increase in soil bulk density; in addition, more irrigation is required. Drainage can reduce the...
