Ecology and environment-friendly soil improvement agent and preparation method thereof

Abstract

The invention discloses an ecology and environment-friendly soil improvement agent, which is prepared from the following raw materials in parts by weight: 15-25 parts of ore soil filler, 7-11 parts of coal gangue, 8-10 parts of straw, 10-20 parts of mixed grass meal, 3-5 parts of compound microorganisms, 5-7 parts of humate, 8-12 parts of excrement of livestock, 4-6 parts of desulfurized gypsum, 6-8 parts of bamboo charcoal powder and 5-7 parts of trace element additives. The soil improvement agent provided by the invention can effectively overcome the imbalance of nutrient elements in soil, improve soil fertility, loosen the soil, improve fertilizer efficiency, increase the contents of organic matters and nutrients, loosen hardened soil, accelerate a process of raw soil ripening and improve or recover land productivity; furthermore, industrial and agricultural wastes are used as most of the raw materials, so that the soil improvement agent is environmentally-friendly and safe; furthermore, the preparation method provided by the invention is lower in material cost, easy in obtaining of raw materials, simple in technology and easy to operate and in realization of industrial production, thus having higher practical value and a good application prospect.

Description

technical field [0001] The invention relates to the technical field of planting soil improvement, in particular to an ecological environment-friendly soil improver and a preparation method thereof. Background technique [0002] In recent years, with the increase of agricultural production activities and the excessive use of chemical fertilizers, the soil structure has been destroyed, resulting in soil compaction, low yield and poor quality of agricultural products, and people's consumption is harmful to human health. At the same time, there are large areas of sandy soil, saline-alkali land, acid soil, rocky desert land, desert land, soaked swamp land and other common soils in China. These soils are not suitable for planting crops or other crops, resulting in waste of land resources. At present, in order to maintain soil nutrients from depletion, it is necessary to apply soil amendments to poor soil to improve the physical, chemical and biological properties of the soil to ma...
