高产单位水稻施肥多半采用定性及形态指标施肥,这种经验法施肥难以在生产上推广应用,针对这种局限性,我们吸取当前各种施肥技术(特别是近几年来省肥栽培施肥技术)的可取之处,从1976年开始对早稻施肥方法进行研究,经过几度改进、试验、摸索,使早稻施肥由传统施肥(常规法、经验法)个性规律初步找到了水稻施肥的共 Most of the high-yielding units of rice fertilization use qualitative and morphological indicators of fertilization, this empirical fertilization is difficult to promote the application of production, in view of this limitation, we draw on the current various fertilization techniques (especially in recent years, fertilizer and fertilization techniques) Desirable, starting from 1976 on the method of early rice fertilization research, after several improvements, tests, groping, so that the early rice fertilization by the traditional fertilization (conventional method, the law of law) to find the initial law of the individual fertilizers
