摘要
通过对温麦6号超高产麦田跟踪调查测定,得出了该品种实现每公顷9093kg籽粒产量时,各重要生育时期的群体数量、干物质积累量、叶面积系数、挑旗后各叶层叶面积系数的动态指标,及其相应各时期的个体质量动态指标。明确了产量构成三因素分别为:每公顷成穗628.5万,每穗35.25粒,千粒重40.17g。同时还与鲁麦22号高产田的相应指标进行了对比分析,并提出了改进技术措施。
Experiments and investigations on Wenmai 6 were conducted in super-high-
yielding wheat field. The number of tillers, the amount of dry matter accumulation, and the leaf
area index at each important developing stage, the dynamic vertical distribution of the leaf area
index at each leaf layer after booting, and the individual quality dynamic index at each stage un
der the grain yield level of 9093 kg per ha were achieved. The yield components were 628. 5 ×
104 spikes per ha, 35. 25 grains per spike, 40. 17 g per grain. Meanwhile, comparision and analy
sis in those index mentioned above between Wenmai 6 and Lumai 22 were made, and the ways to
improve were discussed.
