Soil fertility increasing agent and preparation method and application method thereof

Abstract

The invention discloses a soil fertility increasing agent and a preparation method and an application method thereof, and belongs to the field of agricultural production. The soil fertility increasing agent is prepared by mixing plant ash, a nitrogen fertilizer, a phosphate fertilizer, biological manure, a nutrient solution and organic humus; the biological manure and the nutrient solution are obtained by the steps of carrying out mixed fermentation of animal dung, calcium oxide, calcined red mud, urea, vinasse, soybean straw, peanut seedlings and a backing material abandoned after cultivation of edible fungi, and then filtering to obtain a filter residue being the biological manure and a filtrate being the nutrient solution; the organic humus is obtained by the steps of carrying out piling fermentation of leaves, wheat straw, green corn straw and river bottom sludge and then carrying out sterilization treatment. Through mixing of the specially-prepared biological manure and organic humus with the plant ash, nitrogen fertilizer, phosphate fertilizer and other conventional fertilizers, the fertility increasing agent is rich in a variety of trace elements and soil required biomass, fully meets the needs of the soil, also facilitates the absorption and utilization of the soil, and enhances the soil fertility.

Description

technical field [0001] The invention relates to chemical fertilizers used in the field of agricultural production, in particular to a soil fertilizer and its preparation and use methods. Background technique [0002] In agricultural production, the fertility of the land will decrease after years of continuous planting of crops, and continued planting on the land will lead to a reduction in crop yield. In the prior art, the land with reduced fertility is generally stopped planting for one to two seasons, which is called "resting ground". During this period, the land is fertilized and topdressed with various fertilizers. In the prior art, organic fertilizers, organic fertilizers and chemical fertilizers are generally used to fertilize the land, or measures such as straws, increasing soil microbial activities, and increasing soil enzymes are used to fertilize the land. Among these fertilization methods, the use of straw Fertilizer is to directly bury crop stalks in the land, w...

Problems solved by technology

In the prior art, organic fertilizers, organic fertilizers and chemical fertilizers are generally used to fertilize the land, or measures such as straws, increasing soil microbial activities, and increasing soil enzymes are used to fertilize the land. Among these fertilization methods, the use of straw Fertilizer is to directly bury crop straws in the land, which takes a long time. When methods such as increasing soil microbial activities and increasing soil enzymes are used, the cost is very high, so bio-organic fertilizers are generally used for fertilization
