摘　　要：为了研究不同高产玉米品种在黑龙江春玉米区种植的可行性,以‘先玉335’和‘郑单958’为试材,通过对比分析,探讨2个品种在该地区种植的灌浆和脱水特性。结果表明,‘先玉335’灌浆迅速,生理性脱水快,产量高;‘郑单958’灌浆持续期略长,前期和中期灌浆速率较‘先玉335’慢,但后期灌浆速率和自然性脱水速率都快,产量较高。从气温和降雨特点来看,在黑龙江春玉米种植区部分积温较高地区,可考虑将‘郑单958’作为品种更替及多样化的备选材料。In order to study the feasibility of different high-yield maize planted in the planting area ofHeilongjiang spring maize,‘Xianyu 335＇and‘Zhengdan 958＇varieties were selected and the grain fillingand dehydration characteristics of them were analyzed.The quick velocity of grain filling,physiologicdehydration,and higher yield in‘Xianyu 335＇were found,whereas those of long duration period of grainfilling in‘Zhengdan 958＇and slow velocity of grain filling in early and middle of filling period were compared.While the quick velocity of grain filling and natural dehydration,and high yield were found in the later offilling period of‘Zhengdan 958＇.It is possible for‘Zhengdan 958＇as a candidate for variety alternate anddiversification to be planted in the zone which has higher accumulated temperature in Heilongjiang province.
