摘要: 以正大619、迪卡008及玉美头105为试验材料,在免耕条件下,探讨不同播种深度对玉米(Zea mays L.)的生育期、出苗率、倒伏率、植株性状、穗部性状及产量的影响,并探索出免耕条件下不同玉米品种在广西德保适宜的播种深度。结果表明,在土壤结构疏松的条件下,不同的播种深度对玉米生育期、出苗率、倒伏率及植株性状的影响较小,差异不显著。播种深度对部分穗部性状有影响,不同的玉米品种受影响的穗部性状则不同。正大619、迪卡008和玉美头105的最佳播种深度分别为12、5和12 cm,适宜播种深度范围为5~15 cm。

Abstract: In order to find suitable sowing depths for maize varieties under no-tillage conditions in Debao,Zhengda 619,Dika 008 and Yumeitou105 were used as experimental materials to study the effects of different sowing depths on growth period,emergence rate,lodging resistance rate,plant traits,panicle traits and yield of maize. The results showed that under the condition of loose soil,the influence of different sowing depths on growth period,emergence rate,lodging resistance rate and plant traits was small,and the difference was not significant. Some panicle traits were influenced by different sowing depths,which varied among different varieties. The optimum sowing depths of Zhengda 619,Dika 008 and Yumeitou 105 were 12 cm,5 cm and 12 cm,respectively. And the range of suitable sowing depth was 5~15 cm.
