试验表明，油菜地膜覆盖有着明显的增温和保墒作用。盖膜比露地５ｃｍ日平均土温提高３．０７℃，耕层２０ｃｍ日平均土温提高１．９０℃；０～１０ｃｍ的土层含水量提高３．９６％，１０～２０ｃｍ土层含水量提高２．４１％；研究还表明地膜油菜较对照成熟早７ｄ左右，而且经济性状有不同程度的改善，其中以产量性状中的角粒数、千粒重、单株角数变化较大，分别增加３．７７粒、０．６７ｇ、５１．６个。地膜油菜公顷产３５５０．２０ｋｇ，比对照增产５４．２３％。
Experiments show that rape mulching has obvious warming and soil moisture effect. The daily average soil temperature increased by 3.07 ℃ and the average daily soil temperature increased by 1.90 ℃ in 5 cm of open field. The soil moisture content in 0-10 cm soil layer increased by 3.96% and the water content in 10-20 cm soil layer increased 2.41%. The research also showed that the rapeseed was mature about 7 days earlier than the control, and the economic traits had improved to some extent. Among them, the number of the grains, the 1000-grain weight and the number of the single plant in the yield traits varied greatly. 77 tablets, 0.67g, 51.6. Rape mulched hectare production 3550.20kg, 54.23% increase compared with the control.
