1983年以来,我们在油菜上进行了覆膜应用,结果增产显著,一般亩增产菜籽50~100公斤,增产率在50%左右。油菜覆膜栽培,一般有直播覆膜和育苗移栽覆膜两种形式。直播油菜的覆膜栽培(一)整地。直播油菜的覆膜栽培在整地质量上比不覆膜的高得多。要做到厢平、厢宽一致和抢墒将地耙细。在拉绳开好沟后要用锄头将厢面整平,膜应比厢宽33厘米。
Since 1983, we have rape coating application, the results significantly increased yield, the general increase of 50000 acres of rapeseed yield increase rate of about 50%. Rape laminating cultivation, generally live film and seedling transplanting film in two forms. Live rape covered film cultivation (A) site preparation. Laminated rapeseed cultivation in the quality of land preparation is much higher than the non-coated. To be flat, the same car width and grab the soil harrow fine. In the drawstring after a good ditch to hoe car flat, the film should be 33 cm wide than the car.
