| 摘 要： | 采用四因素五水平二次回归旋转组织合设计系统的研究了不同农艺措施对冬小麦分蘖成穗数的动态影响，结果表明，播期是影响冬前分蘖的首要欠之；播量是影响人生分蘖的首要因素，播期次之；而播量，播期，氨磷施用量相互配合对分蘖成穗数起决定作用。

| Abstract: | The dynamic effect of different agrotechnology on tilling and ears development of tillers was studied systematically with parabolic regrossion revolution design for four factors.The results show that sewing time had the most important effect on tilling before winter stage, next came sowing norm;sowing norm had the first effect on spring tillers,next came sowing time;and the ears development of tillers were decided by the cooperation of sowing time,sowing norm and amount of nitrogen and phosphate fertilizer applied.Analysis showed that sowing time and sowing norm had decisive effect on the number of tiller on rich land,but the number of ears was decided not only by the former two factors but also by the amount of nitrogen and phosphate fertilizer applied. |
