Abstract

The invention discloses a first rice crop ear granule fertilizer based on rice-ratooning rice and a preparation method thereof. The first rice crop ear granule fertilizer based on the rice-ratooning rice comprises nitrogen, phosphorus pentoxide and potassium oxide according to a certain ratio. The preparation method comprises the steps of A, weighing urea and feeding the urea into a melting tank at the top of a high tower; B, weighing raw materials such as ammonium chloride, ammonium sulfate, monoammonium phosphate, potassium chloride and heptahydrate, and feeding the raw materials into a hightower mixing tank to be mixed and melted; C, mixing the melted urea and the uniformly mixed raw materials; D, spraying out the urea which coats the raw materials from a nozzle, and cooling and granulating the urea which coats the raw materials in the landing process; E, obtaining a granular fertilizer by using a screen; F, cooling the granular fertilizer and spraying anti-blocking substances to the granular fertilizer; and G, continuing to cool the fertilizer, and packaging and sealing the fertilizer. The first rice crop ear granule fertilizer based on the rice-ratooning rice, disclosed by the invention, has the advantages that the growth and development of first rice crops and yield formation of the first rice crops can be promoted, the first rice crop ear granule fertilizer based on therice-ratooning rice is beneficial for germination and earing of axillary buds of the ratooning rice, and high yield of double-season rice is guaranteed, the water solubility is good, granules are uniform, the dissolution is fast, nutrition supply is timely, the concentration is high, the absorption is easy, and the nutritional requirement of longer growth period of the rice can be satisfied.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and more specifically relates to a first-season rice panicle-grain fertilizer suitable for rice-ratio-ratonic rice, and also relates to a method for preparing a first-season rice panicle-grain fertilizer suitable for rice-ratio-ratonic rice. It is suitable for the use of rice panicle and grain fertilizer in the first season. Background technique [0002] Rice is one of the main food crops in China, and stably increasing rice production is the key to ensuring food security. In the past 40 years since 1949, although the average annual increase of rice planting area was small, the average annual increase of per unit yield was 4.53%, which made the total rice output increase year by year, with an average annual increase of 5.69%. However, in recent years, it has become more and more difficult to increase the yield of rice per unit area, with an annual increase of less than 3%. At the same time,...
