Abstract

The present invention belongs to the technical field of agricultural fertilizers, and provides a special high-silicon rice fertilizer, a production method and an application method thereof, wherein the fertilizer comprises, by mass, 10-18% of silicon fertilizer granules, 30-38% of large granule urea, 25-28% of diammonium phosphate, and 6-35% of potassium chloride. According to the present invention, the high-silicon fertilizer is produced through extrusion granulation, and the produced high-silicon fertilizer is added to the special fertilizer for rice according to the ratio to obtain the special high-silicon rice fertilizer; and the obtained special high-silicon rice fertilizer is used for carrying out basal application on rice according to the use amount of 30-35 kg / mu, the yield is significantly increased, plant diseases and insect pests are reduced even eliminated, and the quality of rice is improved.

Description

Technical field [0001] The present invention relates to the technical field of agricultural fertilizers, and in particular to a high-silica rice special fertilizer and its production and application methods. Background technique [0002] It has been determined that silicon is one of the essential nutrients for rice. The silicic acid content in rice is about 10 times that of nitrogen and 20 times that of phosphorus. Silicon can not only increase rice production, but also has an important impact on the quality of rice. In 2008, the sky-high price of rice imported from Japan was sold in the Beijing market at 98 yuan per kilogram. It is said that this rice was produced using silicon fertilizer. [0003] At present, the content of silicon in the soil is relatively rich, but the absorption rate of rice is extremely low. The demand for silicon nutrients in rice must be supplemented by the application of silicon fertilizer. Most of the silicon fertilizers currently on the market a...
