利用地膜覆盖栽培技术对甘蓝型油菜进行栽培比较试验。结果表明：地膜覆盖直播较未覆地膜直播早熟5d，较覆膜移栽早熟2d，较未覆膜移栽早熟7d；地膜覆盖直播较未覆膜直播增产88．24％；地膜覆盖移栽技未覆膜移栽增产46．15％。证明这项技术在淮北地区有推广前景。
Cultivation of Brassica napus by plastic film mulching cultivation. The results showed that the direct seeding coverage of mulching with film mulching was 5 days earlier than direct mulching without mulching, 2 days earlier with mulching transplanting, 7 days earlier with mulching without transplanting, 88.24% No film transplanting increased yield 46.15%. Prove that this technology has promotion prospect in Huaibei area.
