Embodiment 1

[0015] This embodiment is prepared by mixing the following raw materials in mass percentage, 50% of sand, 20% of organic fertilizer, and 30% of waste substrate. After mixing, it can be directly sprinkled on the soil for crop planting, and the application amount will gradually decrease with the years, and 25m can be applied in the first year 3 / 667m 2 , which can be halved in the second year.

[0016] The above-mentioned organic fertilizer is fully decomposed farm organic sheep manure. If the decomposition is not complete, add water to the farm organic sheep manure to adjust the humidity to 45%-55%, add bran and biomycin at 0.6‰ mass percentage (bran: biomycin = 5:1), and cover it with plastic cloth Obtained after 7-15 days of fermentation.

[0017] The above-mentioned waste matrix is ​​the waste after seedling raising and cultivation for 2-3 crops. After high-temperature sterilization, nitrogen, phosphorus and potassium compound fertilizer is added at 5% by mass, and water ...

Embodiment 2

[0019] This embodiment is prepared by mixing and preparing raw materials according to the following mass percentages, 48% of sand, 20% of organic fertilizer, and 32% of waste substrate. After mixing, it can be directly sprinkled on the soil for crop planting, and the application amount will gradually decrease with the years, and 25m can be applied in the first year 3 / 667m 2 , which can be halved in the second year.

[0020] The above-mentioned organic fertilizer is fully decomposed farm organic sheep manure. If the decomposition is not complete, add water to the farm organic sheep manure to adjust the humidity to 45%-55%, add bran and biomycin at 0.6‰ mass percentage (bran: biomycin = 5:1), and cover it with plastic cloth Obtained after 7-15 days of fermentation.

[0021] The above-mentioned waste matrix is ​​the waste after seedling raising and cultivation for 2-3 crops. After high-temperature sterilization, nitrogen, phosphorus and potassium compound fertilizer is added ...

Embodiment 3

[0023] This embodiment is prepared by mixing the raw materials in the following mass percentages, 60% of the river sand in the concentric sand field in Ningxia, 15% of the organic fertilizer, and 25% of the waste matrix. Gradually reduce, 25m can be applied in the first year 3 / 667m 2 , which can be halved in the second year.

[0024] The above-mentioned organic fertilizer is fully decomposed farm organic chicken manure. If the decomposition is not complete, add water to the farm organic chicken manure to adjust the humidity to 45%-55%, add bran and biomycin at 0.6‰ mass percentage (bran: biomycin = 5:1), and cover with plastic cloth Obtained after 7-15 days of fermentation.

[0025] The above-mentioned waste matrix is ​​the waste after seedling raising and cultivation for 2-3 crops. After high-temperature sterilization, nitrogen, phosphorus and potassium compound fertilizer is added at 5% by mass, and water is added to adjust the humidity to 65%. It is covered with plastic...

Abstract

The invention relates to a clayed soil improvement agent. The clayed soil improvement agent is mainly prepared by compounding the following raw materials by mass percent: 40-60% of sand, 15-25% of organic fertilizer and 25-35% of waste matrix. The clayed soil improvement agent has the advantages that firstly mechanical composition and texture of soil can be improved, physical and chemical properties of clayed soil can be improved, fertilizer utilization rate can be increased, and crop growth environment can be improved; secondly, after the clayed soil is applied, soil bulk density is reduced by 5.2%, ventilation porosity is increased by 31.5%, soil organic matter is increased by 18.6%, soil alkali-hydrolyzable nitrogen is increased by 5.9%, and rapidly available phosphorus is increased by 8.4%; and thirdly, raw material resources are rich, a manufacturing process is simple, the clayed soil improvement agent is easy to use in the field, production cost is low, and no side or toxic effect is produced.

Description

technical field [0001] The invention relates to a soil conditioner, in particular to a soil conditioner used in sticky soil. Background technique [0002] Ningxia has vigorously developed facility agriculture, which has become a new bright spot for farmers to increase their income steadily. Currently, 85% of facility agricultural product production bases have passed the pollution-free and green food certification. The varieties mainly include vegetables, fruits, flowers, etc. However, during the construction of the facility agricultural base, the surface soil is used to build the greenhouse, and the backfill soil is the deep soil excavated for the greenhouse. There is a large amount of cohesive soil in this kind of backfill, which has low organic matter content, compact soil structure, hard soil, excessive soil viscosity, poor water permeability and air permeability, and the organic matter and nitrogen, phosphorus, and potassium in the soil cannot be well mineralized. If it...
