Method for preparing green high-efficiency soil conditioner

Abstract

The invention relates to a method for preparing a green high-efficiency soil conditioner, which belongs to the technical field of conditioner preparation. According to the invention, substances such as bentonite and fly ash are mixed, a mixture is applied to the irrigated paddy field, water dropwort is planted in the paddy field, and loach can be cultured in the paddy field, after the water dropwort grows to a certain height, the water dropwort is cut and the loach is removed, the paddy field after the water is discharged is insolated, and the soil on the surface of the paddy field is collected, the black powder is obtained through drying and crushing processes, polished rice and glutinous rice are taken as the raw materials for fermentation to obtain a precipitate slurry, and the precipitate slurry is mixed with the black powder to obtain the product. The green high-efficiency soil conditioner does not contain heavy metal, cannot generate harm on soil ecology, increases the output and quality of an agricultural product; has the effects of water retention, fertility increasing and ventilating effects, the water-holding capacity is increased by 15.6-25.3%, the unit weight of the soil is reduced by 0.04-0.05 g / cm<3>, and the agricultural product output can be obviously increased.

Description

technical field [0001] The invention relates to a preparation method of a green and high-efficiency soil conditioner, belonging to the technical field of conditioner preparation. Background technique [0002] Soil conditioner is made of agricultural water-retaining agent and natural peat rich in organic matter and humic acid or other organic matter as the main raw materials, supplemented by biologically active ingredients and nutritional elements, and processed by scientific technology. The three soil conditioning properties of water retention, fertilization, and ventilation can break soil compaction, loosen soil, improve soil air permeability, reduce soil bulk density, promote soil microbial activity, and enhance soil fertilizer and water permeability; it can improve soil and control deserts. Conserve water and fight drought, enhance crop disease resistance, increase crop yield, improve the quality of agricultural products, restore the original ecology of crops and other fu...

Problems solved by technology

[0004] The technical problem to be solved by the present invention: the raw materials for preparing the soil conditioner contain heavy metals, long-term use in the soil will undoubtedly cause the accumulation of heavy metals in the soil, which will cause a kind of harm to the soil ecology and affect the quality of agricultural products. Ionized water, bentonite and fly ash are mixed to obtain a mixed slurry, which is then applied to the irrigated paddy field, and then planted with water celery and cultured loach in the paddy field. After the water celery grows to a certain height, it is cut off. Water celery and loach are removed, the watered paddy field is exposed to the sun, and the soil on the surface of the paddy field is collected, dried and crushed to obtain a black powder, which is then fermented using japonica rice and glutinous rice as raw materials to obtain a sediment slurry material, and finally mix it with black powder to get a green and efficient soil conditioner
