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。
Through tracking investigation on the super high yielding wheat field of Wenmai 6, the population quantity, the dry matter accumulation, the leaf area coefficient, the leaf layer leaf after the flagging were obtained when the grain yield was 9093kg per hectare. The dynamic index of area coefficient and the individual quality dynamic index of corresponding period. Clearly, the three factors of yield formation are as follows: 6.285 million spikelets per hectare, 35.25 spikes per spike, 40.17 g grain weight. At the same time, the corresponding indexes of Lumai22 high yielding field were compared and analyzed, and the improved technical measures were put forward.
