Problems solved by technology

However, the fertilizer component of this invention does not involve the silicon-calcium element that has a significant impact on lodging, but only utilizes the synergistic effect of nitrogen and potassium, and does not utilize the synergistic effect of nitrogen, phosphorus, potassium, silicon, calcium and trace elements
The improvement of anti-lodging ability is limited, and the price of resin coating is extremely high, which lacks practical production and application value

Abstract

The invention relates to a special formula fertilizer for direct seeding rice lodging resistance and its preparation method and application. With granular urea as the core and silicon calcium magnesium phosphorus potassium fertilizer as the coating layer, a modified inorganic phosphate binder is sprayed in a granulator, and added Trace elements are used to prepare coated urea rich in trace elements such as silicon and calcium, and then compound the macroelements N, P, and K according to the nutritional requirements of direct-seeded rice to obtain a special formula fertilizer for lodging resistance of direct-directed rice. This process balances the nutritional requirements of direct-seeding rice by achieving nitrogen control, stabilizing phosphorus, increasing potassium, and supplementing silicon and calcium, improves the lodging resistance and yield of direct-seeding rice, reduces the cost of fertilization, and has greater economic benefits and promotion value .

Description

technical field [0001] The invention relates to a special formula fertilizer for direct-seeding rice, a preparation method and application thereof, and belongs to the technical field of fertilizer preparation and utilization. Background technique [0002] Rice direct seeding is a light and simple cultivation technique of rice that has been rapidly expanded in my country in recent years. It has the outstanding advantages of labor saving, labor saving, high efficiency, and is conducive to mechanical operation. In recent years, with the development of rural economy and the transfer of rural labor force, the level of mechanization of farmland has been improved, and the direct seeding planting method has been welcomed and adopted by more and more rice farmers. According to incomplete statistics, the global direct-directed rice planting area has reached about one-third of the rice planting area, and the direct-directed rice planting area in my country also exceeds 15%. , coupled ...
