摘要
为选取有效种植方式指导玉米生产,以先玉335为试验材料,研究不同种植方式对玉米的产量和农艺性状的影响。结果表明:平作的玉米产量高于平作垄管和垄作,前者与后两者产量差异达极显著水平。平作种植方式较垄作种植方式增产7.2%。采取平作种植的玉米在棒三叶叶面积、株高、穗粗和穗行数等性状上表现突出。
In order to select effective plant pattern to guide maize production, Xianyu 335 was taken as experimental material to study the effects of different plant patterns on maize agronomic traits and the yield. The results showed that the flat planting could improve the yield, which higher than that of flat planting with ridge management and ridge tillage,there was significant difference between the former and the latter. Flat planting could increase the yield by 7.2 % compared with ridge of three ear-leaves, plant height, ear diameter and row tillage. There were significant advantages in the leaf area number under the flat Dlantin; nattern.
