| 摘要: |
| 采用不同覆膜方式，对渭北旱塬的油菜栽培技术进行研究。结果表明，覆膜栽培增产效果明显，尤以膜上穴播栽培增产显著，比露地栽培增产71.28%；膜侧栽培增产效果次之，比露地增产33.36%。1999～2001年3年大面积覆膜栽培的实践证明，膜上穴播不便于机械化操作，且费工费时；膜侧栽培利于机械化种植，群众乐意接受，3年累计在渭北旱原推广2.85万hm2，增产油菜籽1.85万t，新增产值3 326.2万元。 |

| Study into film-covering rape cultivation technique and its application in North Weibei Dry-land of Shaanxi |

| Abstract: |
| Experiments showed that the rape-yield was increased significantly by various ways of film covering,especially,the bunch planting was the highest,the yield could increase 71.8% compared with non-film-covering cultivation.Furrow planting beside film was the follow-up,33.6% higher than CK.By means of three-year extensive practice from 1999 to 2001,it has been found that bunch planting is inconvenient for mechanized operation and it is a waste of time and labour.Furrow planting beside film is convenient for mechanized planting,and the mass would like to accept.During the three years,planting area of the film-covering rape was 28 500 hm2,rape yield increased 18 500 t,increasing value 33 262 000 RMB in the north Weibei dry-land. |
