小麦精播高产技术是山东农业大学余松烈教授等研究成功的一项小麦高产栽培新技术,它的指导思想是处理好麦田群体与个体的矛盾,建立合理的群体结构,从而达到高产低耗的目的。其基本内容是:在地力比较高、土肥水条件比较好的基础上,降低基本苗,控制无效分蘖和过多的有效分蘖,使麦田的群体较小,群体的动态结构比较合理,从而改善群体内有效分蘖的光照条件,促进个体发育健壮,成穗率高,单株成穗数多,穗大粒重。从1985
The technology of high-yielding wheat sowing is a new high-yielding wheat cultivation technique successfully researched by Prof. Yu Songlie from Shandong Agricultural University. Its guiding ideology is to deal with the contradiction between the groups and individuals in the wheat field and establish a reasonable group structure so as to achieve the purpose of high yield and low consumption . Its basic content is: on the basis of relatively high ground force and soil fertility and water conditions, reducing basic seedlings, controlling ineffective tillers and excessive effective tillers make the population of wheat fields smaller and the dynamic structure of the population more reasonable, so as to improve the population Effective tillering within the light conditions to promote the development of robust individuals, into a high rate of spike per plant number, spike large grain weight.
