Problems solved by technology

[0002] At present, domestically produced biological fertilizers, organic fertilizers, inorganic compound fertilizers, bio-organic fertilizers, organic-inorganic compound fertilizers, etc. have certain defects in use and effect: single application of biological fertilizers and organic fertilizers can improve soil physical and chemical properties and improve land quality. Structure and soil environment to improve the quality of agricultural products
However, it is difficult to increase the yield of crops: single application of inorganic compound fertilizers or inorganic fertilizers can increase the yield of crops, but long-term application destroys soil physical and chemical structure and soil fertility
At the same time, the utilization rate of chemical fertilizers is very low, only about 30%.

Abstract

The invention relates to a ternary slow-controlled compound fertilizer. The ternary slow-controlled compound fertilizer is prepared by mixing an inorganic compound fertilizer and a granular bio-organic fertilizer according to the weight ratio of (2:1)-(3:2); wherein the contents of N, P2O5 and K2O in the inorganic slow-controlled compound fertilizer are respectively 8%, 8-15% and 8-15%. By virtue of the slow-controlled compound fertilizer disclosed by the invention, the application amount is less, the quality of crops can be improved, the yields of crops is increased by 25%, yields of fruits and vegetables are increased by above 35%, and physical and chemical properties of the soil, soil structure and soil environment can be improved and the soil is upgraded by one level after the compound fertilizer is continuously applied for three years.

Description

Technical field [0001] The invention relates to a large ternary (biological, organic and inorganic) slow-control compound fertilizer and a preparation method thereof, belonging to the technical field of fertilizers and fertilizers. Background technique [0002] At present, domestically produced biological fertilizers, organic fertilizers, inorganic compound fertilizers, bio-organic fertilizers, organic-inorganic compound fertilizers, etc., have certain defects in their use and effects: single application of biological fertilizers and organic fertilizers can improve soil physical and chemical properties and improve land Structure and soil environment improve the quality of agricultural products. But it is difficult to increase the yield of crops: single application of inorganic compound fertilizer or inorganic chemical fertilizer will increase the yield of crops, but long-term application destroys the physical and chemical structure of soil and soil fertility. At the same time, t...
