Problems solved by technology

Phosphorus-deficient rice plants are often dark green, with narrow and upright leaves, dead lower leaves, reduced tillers, poor root development, and growth stagnation, which often lead to rice shrinkage and red seedlings, delaying the growth period, and seriously affecting yield; Promote the synthesis, decomposition and transfer of carbohydrates, and help nitrogen metabolism and protein synthesis. Therefore, the more nitrogen is applied, the demand for potassium will increase accordingly. Potassium activates many important enzymes in rice. Potassium can also improve photosynthesis and increase the carbohydrate content of the rice body, making the cel

Abstract

The invention relates to the technical field of slow release fertilizer, in particular to a rice-dedicated slow release fertilizer and a preparation method thereof. Raw materials include organic fertilizer, monopotassium phosphate, sulfate, urea and medical stone powder and can also include chitosan sodium glycero-phosphate temperature-sensitive gel. The rice-dedicated slow release fertilizer is comprehensive and balanced in nutrition; through reasonable arrangement of a coating structure, nutrient release is matched with rice required fertilizer, and therefore the nutrient resource utilization rate is raised; physiological disease resistance of rice is enhanced, the lodging-resistance capability is enhanced, the demand of rice in the maximum absorption period can be met, therefore, the yield of rice is increased, and the quality of rice is improved.

Description

technical field [0001] The invention relates to the technical field of slow-release fertilizers, in particular to a special slow-release fertilizer for rice and a preparation method thereof. Background technique [0002] Rice is the staple food of the world's population, and it is also the main source of nutrition and energy for people in China and even Asia. Nitrogen, phosphorus, and potassium are the basic nutrients for rice growth and development. Among them, nitrogen is the core component of important nitrogen-containing organic compounds in rice; phosphorus is one of the important components of cytoplasm and nucleus, and directly or indirectly participates in sugar, protein and fat metabolism, and can also participate in energy metabolism. Part of the high-energy phosphoric acid is the main energy storage place. Therefore, phosphorus is indispensable in cell division and meristem development, and it is more important in the seedling and tillering stages. Phosphorus-def...
