小麦高产栽培中的主要矛盾之一是处理好群体与个体的关系。随着肥力和产量水平的提高,适当降低基本苗,有利于建立合理的群体结构。但减少基本苗必须以满足适宜的穗数为前提。因此,必须掌握分蘖成穗规律及分蘖幼穗发育特性,才能在高产栽培中确定适宜的基本苗,合理利用分蘖成穗。为此于1982～1984年在重庆北碚对几种不同分蘖类型品种进行了调查研究。
One of the major contradictions in high-yielding wheat is to handle the relationship between groups and individuals. With the increase of fertility and yield, it is helpful to establish a reasonable population structure by appropriately reducing the basic seedlings. But to reduce the basic seedlings must be to meet the appropriate number of spikes as a prerequisite. Therefore, we must master the laws of tillering panicle and tillering panicle growth characteristics in order to determine the appropriate high-yielding basic seedlings, rational use of tillers into ear. To this end in 1982 and 1984 in Beibei, Chongqing, several different types of tillers were investigated.
