Abstract

The invention discloses a preparation method of a fertilizer for increasing hybrid rice yield per mu. The method includes steps: stirring kaolin and nitric acid solution, adding P123 and polystyrene microsphere emulsion, continuing stirring, cooling, washing, drying, calcining, cooling and grinding to obtain a first material; stirring talcum powder, sepiolite powder, zeolite powder, a first material and molybdenum trioxide to obtain a second material; well mixing urea, ammonium bicarbonate, precipitated phosphate fertilizers and kiln dust potassium fertilizers, adding EDTA chelated zinc, EDTAchelated manganese, brassinolide and triacontanol, and well mixing to obtain a third material; mixing the second material and the third material, granulating, adopting a coating agent for coating, anddrying to obtain the fertilizer for increasing hybrid rice yield per mu. The fertilizer prepared according to the method enables increasing of rice yield, cost reduction is realized, the fertilizer utilization rate is increased, quality and taste of hybrid rice and common japonica rice are improved, original flavor of rice is recovered, and storage time of the hybrid rice is prolonged by half a year or longer.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a method for preparing fertilizers for increasing the yield per mu of hybrid rice. Background technique [0002] Hybrid rice has very strong growth potential, adaptability and stress resistance, and the rice yield is significantly higher than that of common late rice japonica rice. With the acceleration of industrialization and urbanization, the situation of maintaining arable land area is becoming increasingly severe. The development of industrialization and urbanization requires a large amount of land for construction, which has serious contradictions with maintaining the stability of food production. The increase of construction land will inevitably lead to the decrease of cultivated land. Under the basic premise that the area of ​​cultivated land continues to decrease, increasing rice yield per mu is an inevitable choice for stabilizing grain production. Contents of th...
