摘　　要：采用品种、播期双因素裂区设计,系统研究了不同播期下不同玉米品种品质的差异,旨在找出供试玉米品种最优品质的播期。结果表明,强盛49号和屯玉6号的籽粒蛋白质和脂肪含量都是在第3播期最高;在试验播期内,二者的淀粉含量在晚播处理下高于早播处理;推迟播期,籽粒蛋白质、脂肪含量呈现减少趋势,淀粉含量呈现增加的趋势,表明要获得较好的籽粒品质,可以通过提前播种来实现。研究结果可作为供试品种在类似地区优化品质的参考。Using split plot design of varieties and sowing date double factors, the differences of quality between different maize varieties under different sowing dates were discussed aiming to find out the best sowing date for the tested maize variety. The results showed that protein and fat content in the grain of Qiangsbeng 49 and Tunyu 6 was the highest on the 3rd sowing date; in the test sowing time, the starch content in the grain of Qiangsheng 49 and Tunyu 6 was higher in the late sowing than in the early sowing. With delaying the sowing date, the content of the protein and oil had the tendency to reduce and the starch had the tendency to increase. It showed that the better grain quality can be reached by early sowing. The results of research could be a reference to the cultivation of test variety in similar areas for the quality optimizing.
