| 摘 要： | 渭北旱地油菜采用地膜覆盖栽培，具有良好的增温、保水作用，能促进冬前生长发育、保证幼苗安全越冬，加快油菜的生育进程、提高分枝结角率、增长效果十分显著。但采用垄覆膜和平覆膜不同的覆膜方式，其生育状况及产量结果具有十分明显的差异，垄覆膜平均亩产247．36kg，平覆膜平均亩产为185．15kg，对照（不覆膜）平均亩产99．98kg；垄覆膜较对照增产147.38%，平覆膜较对照增产85．17％。

| Abstract: | Covering winter rape with plastic film in Weibei dryland showed a function in increasing temperature,keeping moisture, improving the growth before winter,ensuring seedlings to survive the winter safely, speeding up its developing process,and raising the percentage of branching and podding,causing a significant yield increase.The results indicated distinct differences in growth and yield between ridge covering and level covering.The average yield of the ridge covering was 247.36 kg per mu. The yield of level covering was 185.15 kg per mu and that of control group (no covering) 99.98 kg per mu. The yield of ridge covering was 147.38% more than that of control group, and the yield of level covering 85.17% more than that of control group. |
