| 摘 要： | 通过设计不同的播种时期和种植密度,研究不同处理造成的温光生态条件和群体结构差异对玉米不同部位子粒灌浆的影响。结果表明,播期和种植密度对玉米中部子粒灌浆速率影响主要表现在灌浆后期,密度影响较大;播期和种植密度对玉米顶部子粒灌浆速率主要是阶段性影响。播期对玉米中部子粒含水率影响较大,种植密度对玉米中部子粒含水率没有影响。

| Abstract: | By designing different sowing date and planting density in the experiment. The effects of temperature and sunshine ecological condition and plant group structure on maize filling were studied. The results indicated that the effects of sowing date and planting density on middle grain filling rate were in filling later stage. The effects of planting density were larger, the effects of sowing date and planting density on top grain filling rate were mainly in different stages. The effects of sowing date on middle grain water content were larger. The effects of planting density on middle grain water content were insignificant. |
