| 摘 要： | 通过四种统计方法分析表明：本区中肥地春小麦成产因素对产量的作用大小依次为穗数＞穗粒数＞粒重，各成产因素间存在一定的互相制约和增进效应。增产途径应以增苗增穗为主，兼顾穗数与穗粒数和粒重的协调发展，其适宜基本苗范围为12.56～30.84万/666．7m2，适宜收获穗数范围为18．28～30．84万／666．7m2，并提出合理的产量结构指标。

| Abstract: | The analysis through four statistical ways showed that the functions of factorsinfluencing yield were quantity of spike, grain and weight of pre grain; there were yet restraint andincrement relationship between factors of yield, The ways to achieve higher yield should lncreasefoundation seedlings and spikes, lower the restrictions of groups to individual, and the proper limitsof foundation seedlings and spikes were 125. 6 ~ 308. 4 thousand/666. 7m2, and 182. 8 ~ 308. 4thousand/666. 7m2,the reasonable structure of yield was also proposed |
