Earing fertilizer special for rice and production method thereof

Abstract

The invention discloses an earing fertilizer special for rice, which is prepared by mixing the components of large-granular urea with nitrogen content being 40-55%, potassium chloride, magnesium sulfate and silicate in a certain proportion. The invention also discloses a production of the earing fertilizer special for the rice. The method comprises the following steps: weighting materials according to the certain proportion; mixing and stirring the potassium chloride, the magnesium sulfate and the silicate, crushing, granulating with a granulator, drying at the temperature of 60-80 DEG C, cooling, screening and packing to obtain mixed batch; and mixing the mixed batch and the weighted large-granular urea, and stirring uniformly to obtain the earing fertilizer special for the rice. The earing fertilizer special for the rice, disclosed by the invention, contains nutrient elements (such as nitrogen, potassium, silicon and magnesium) which are required by the rice in middle-post stage of the rice production, by reasonably applying the earing fertilizer, strong stalks can be facilitate to form, the deterioration of glumous flowers can be reduced, and photosynthesis and prolonging functions of last three functional leaves can be facilitated, so that the thousand seed weight is improved, the rice yield is improved, the quality is improved, the cost is reduced, and the soil environment is improved.

Description

technical field [0001] The invention relates to a compound fertilizer for agricultural production, in particular to a special spike fertilizer for rice. [0002] The invention also relates to a production method of the ear fertilizer specially used for rice. Background technique [0003] At present, the ear fertilizer used in rice production is mainly nitrogen fertilizer (urea), and the application of potassium fertilizer and medium and micro fertilizer is neglected, which is easy to cause greedy green, crazy growth, shading, disease and insect pests, weak straw lodging, and yield reduction. The application of rice panicle fertilizer is at the critical moment of rice vegetative production and reproductive growth. How to apply panicle fertilizer and what kind of panicle fertilizer to apply is related to cost reduction, income increase, high yield and high quality. Therefore, a new technical solution is needed to solve the above technical problems. Contents of the invention...
