油菜地膜覆盖高产栽培技术探讨

Study on High yielding cultivated Technology of Rapeseed Growth Covered by the Ground Plastic

油菜地膜覆盖栽培技术是油菜育苗移栽与地膜覆盖栽培相结合的一项新的栽培技术体系 ,能有效地解决生产中存在的干旱、晚茬、冻害、肥水流失等一系列问题 ,覆膜移栽生育期短 2～ 3d,一般增产 2 0 %～ 30 % ,在沿淮及沿淮以南地区有推广前景。

The technique of rapeseed growth covered by the grourd plastic was a new technique that combined the technique of rapeseed transptanting and growth under the cover with ground plastic.The technique can effectively solve the problem of aridity,freeze injury,and the loss of fertilizer and water 2～3 days of its growth period can be shortened and 20%～30% of yield can be increased.
