Problems solved by technology

Most of the slow-release fertilizers in the prior art are coated with a slow-release agent, the structure of the coating is single, and the nutrient release efficiency and quality of the fertilizer core after coating cannot meet the needs of the actual planting process, so it is urgent to develop a fertilizer. Slow-release fertilizer for rice cultivation solves problems of prior art

Abstract

The invention discloses a slow-release fertilizer for rice planting. The slow-release fertilizer for rice planting comprises a degradable buffer baffle, a degradable fixed clamp buckle, a degradable limiting ring, an adhering layer, a slow release layer, an inner cavity and a fertilizer inner core, wherein the slow release layer is prepared from the following raw materials of sodium hydroxide, polyethylene glycol, rice bran wax, calcium chloride, borax, alum, polyvinyl alcohol and silane coupling agent KH-570; the fertilizer inner core is prepared from the following raw materials of rice hull ash, seaweed meal, brown rice residues, soybean straw, potassium humate, fly ash, illite powder, coconut shell flour, lignin, urea, monoammonium phosphate, potassium fulvic acid, ammonia chloride, diammonium phosphate, monopotassium phosphate, dipotassium phosphate, potassium chloride, potassium sulfate, ferrous sulfate, manganese sulfate, zinc sulfate, ammonium molybdate, ammonia-para-nitrophenolate, EM (effective microorganism) bacterial agent and soil regulator. The slow-release fertilizer for rice planting has the advantages that the slow release property is excellent, the release efficiency and quality of nutrients are effectively improved, and the output and quality of the rice are effectively improved when the slow-release fertilizer is applied to the rice planting.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a slow-release fertilizer for rice planting. Background technique [0002] Organic fertilizers are rich in organic matter and nutrients needed for crop growth. They can not only provide the nutrients needed for crop growth, improve the soil, but also improve crop quality, increase crop yield, promote high and stable crop yields, maintain soil fertility, and increase fertilizer efficiency. Utilization rate, reduce production cost. The full and rational use of organic fertilizers can increase crop yields, improve soil fertility, improve the quality of agricultural products, and increase the effectiveness of soil nutrients. Most of the slow-release fertilizers in the prior art are coated with a slow-release agent, the structure of the coating is single, and the nutrient release efficiency and quality of the fertilizer core after coating cannot meet the needs of the actual plant...
