Problems solved by technology

[0003] Existing rice-specific slow-release fertilizers do not use mineral elements as fertilizers, which cannot cause plant roots and leaves to produce antibodies, are susceptible to pest infestation, have low fertilizer utilization rates, and cause loss when used. The rice yield is low and the soil is not fertile enough. Therefore, here we propose rice-specific slow-release fertilizer and preparation method thereof based on mineral soil

Abstract

The invention discloses a special slow-release fertilizer taking mineral soil as a matrix and used for rice, and a preparation method thereof. The special slow-release fertilizer is prepared from thefollowing raw materials in parts by weight, 10 to 15 parts of bentonite, 3 to 8 parts of clay, 5 to 7 parts of talc, 2 to 6 parts of calcium superphosphate, 1 to 3 parts of urea, 10 to 12 parts of potassium chloride, 15 to 24 parts of nitrogen, phosphorus and potassium, 2 to 6 parts of microbial powder, 5 to 15 parts of aquatic shells, 8-18 parts of shrimp and crab shells, 10 to 25 parts of synthetic water-absorbent resin. The special slow-release fertilizer is beneficial for rice growth; by using a mineral fertilizer, the development of plant root systems can be promoted, and the quality ofcrops is improved; a slow-release performance of the nitrogen-phosphorus-potassium fertilizer is good, the utilization rate of the fertilizer is high, fertilizer loss is reduced, rice yield can be increased, rice quality is improved, and rice resistance is enhanced; and an aquatic shell fertilizer enables rice planting soil to be fertile and is convenient to apply and popularize.

Description

technical field [0001] The invention relates to the technical field of slow-release fertilizers, in particular to special slow-release fertilizers for rice with mineral soil as the substrate and a preparation method thereof. Background technique [0002] Slow-release fertilizers are also known as slow-release fertilizers or controlled-release fertilizers. The nutrient-containing compounds in the fertilizer are released slowly in the soil or the nutrient release rate can be controlled to a certain extent for the continuous absorption and utilization of crops. The purpose of using slow-release fertilizers: (1) to reduce the loss of fertilizer nutrients, especially nitrogen in the soil; (2) to reduce the number of fertilization operations, saving labor and costs; (3) to avoid damage to seeds or fertilizers caused by excessive fertilization. Seedling damage. Slow-acting fertilizers are divided into three categories: (1) insoluble compounds in water, such as magnesium ammonium ...
