Abstract

The invention discloses a fertilizer applicable to one-time fertilizing of rice and a preparation method thereof. A formula of the fertilizer comprises the following components in parts by mass: 18-28parts of nitrogenous fertilizer, 9-12 parts of phosphatic fertilizer, 12-17 parts of potassium fertilizer, and 0-5 parts of zinc fertilizer. The fertilizer has the following advantages: 1) the demandof the rice on nitrogen in growing stage can be effectively met; and the problems of withering in early period, denitriding in later period and unbalanced nutritional components can be avoided; 2) sufficient potassium fertilizer is supplied in later growing period of the rice, so that the lodging resistance of the rice is improved; and 3) the fertilizer is applied in one time, so that the problems such as frequent fertilizing of the rice, hard topdressing, and heavy work in farmlands can be effectively solved; the method is green; the labor is saved; the cost is saved; the efficiency is improved; the agricultural non-point source pollution is reduced; and the fertilizer utilization rate is increased.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a fertilizer suitable for one-time fertilization of rice and a preparation method thereof. Background technique [0002] Rice is one of the main food crops in my country, and its output accounts for one-third of the world, which plays a decisive role in ensuring my country's food security. Rice cultivation operations are complicated. In terms of fertilization, the traditional fertilization method includes at least three fertilizations of basal fertilizer, tiller fertilizer and panicle fertilizer. First of all, the paddy field growth environment of rice makes it more difficult to topdress than dryland crops; secondly, the traditional topdressing method mostly adopts the method of spreading, and most of the fertilizer dissolves in the paddy field, and some of it cannot be dissolved in water in time due to the shelter of rice itself. , causing waste and threatening environmenta...
