| 中文摘要: |
| 以当地糯玉米主栽品种垦粘1号和京科糯2000为对照，在5个种植密度下对沈糯9号及两个当地对照品种的鲜穗产量、鲜籽粒产量、穗部性状、植株性状及熟期进行了研究。结果表明：密度对三个品种产量的影响达极显著水平；各密度下鲜穗产量、穗长、穗粗、穗行数均显著高于垦粘1号和京科糯2000；籽粒深度、行粒数、百粒重及株高与京科糯2000相当，显著高于垦粘1号，但穗位显著低于京科糯2000；沈糯9号熟期较垦粘1号和京科糯2000分别晚6 d和早9 d。综上所述，沈糯9号在产量、穗部性状及田间长势均优于垦粘1号和京科糯2000，且填补了垦粘1号和京科糯2000之间的熟期空白，因此，沈糯9号在黑龙江省东南部乃至全省的开发前景十分可观。 |
| 英文摘要: |
| Fresh ear yield, fresh grain yield, panicle traits, plant characteristics and maturation periods of the waxy corn Shennuo 9 were studied under five densities using local main cultivar Kennian1 and Jingkenuo 2000 as control. The results show that effects of density on the three varieties were significant; fresh ear yield, spike length, ear diameter and ear rows of Shennuo 9 were obviously higher than that of Kenian1 and Jingkenuo 2000; grain depth, grains per row, 100-grain weight and plant height of Shennuo 9 is comparable to Jingkenuo 2000 whereas significantly higher than Kennian1. The ear position of Shennuo 9 is lower than that of Jingkenuo 2000. Maturation period of Shennuo 9 was six later days and nine days earlier than that of Kennian1 and Jingkenuo 2000, even fill in gaps in maturation period of Kennianl and Jingkenuo 2000. In conclusion, yield, panicle traits and field performance of Shennuo 9 are better than that of Kennian1 and Jingkenuo 2000, indicating that Shennuo 9 is suitable for Southeast of Heilongjiang Province. |
