The invention discloses special sustained-release
panicle fertilizer for sweet glutinous rice and a preparation method of the special sustained-release
panicle fertilizer, and relates to the field ofagricultural
fertilizer. The special sustained-release
panicle fertilizer for the sweet glutinous rice is provided base on the basis of the problems that existing fertilizer cannot meet the
nutrient demands of the sweet glutinous rice, the release cycle of the fertilizer is short, the yield of fragrant rice is low and the content of
aroma effective ingredients in the fragrant rice is low. The special sustained-release panicle fertilizer for the sweet glutinous rice is prepared from the following raw materials in parts by weight: 10 to 30 parts of
organic fertilizer, 60 to 80 parts of inorganicfertilizer-trace fertilizer mixed fertilizer, 5 to 10 parts of Chinese herbal medicinal additive, 1 to 3 parts of special fertilizer synergist and 1.3 to 1.5 parts of
polyvinyl alcohol; the inorganicfertilizer-trace fertilizer mixed fertilizer consists of
inorganic fertilizer and trace fertilizer. The preparation method comprises the steps of preparing and mixing the
organic fertilizer, the
inorganic fertilizer-trace fertilizer mixed fertilizer, the Chinese herbal medicinal additive and the special fertilizer synergist and granulating. The special sustained-release panicle fertilizer for thesweet glutinous rice, disclosed by the invention, has the advantages that
nutrient demands of the sweet glutinous rice at all growth nodes during rice panicle period of the sweet glutinous rice are met, the yield of the sweet glutinous rice is improved, the accumulation amount of
nutrient elements is improved, the quality of the sweet glutinous rice is improved, the content of characteristic
aroma substances in the sweet glutinous rice is increased and the
infection rate of the sweet glutinous rice to
pathogenic bacteria is reduced.
