小麦高产群体质量栽培,是以合理的群体起点为基础,使群体和个体、地上部与根系、营养器官与生殖器官等都能够比较健全而协调的发展,从而能经济有效地利用光能和地力。在生育前期促进形成壮苗早发;中期减少无效分蘖发生,控制最高茎蘖苗数,提高茎蘖成穗率;后期促根保叶,促花保花,延缓衰退速度,增大穗形、提高粒重,从而实现高产目标的栽培方式。
Quality cultivation of high-yielding population of wheat is based on a reasonable starting point of population, which enables the development of population and individual, shoots and roots, vegetative organs and reproductive organs so that they can utilize light energy and soil fertility economically . Promote the formation of early vigorous growth in the early stage of fertility; reduce the occurrence of ineffective tillering in the middle stage, control the maximum number of tillering seedlings and increase the percentage of stem tillering into ear; promote the leaf retention and flower conservation at the later stage, delay the decline rate, increase the spike shape, Improve grain weight, in order to achieve the goal of high yield cultivation methods.
