不同颜色地膜覆盖对油菜生长发育及产量的影响

Effects of Different Color Plastic Film Mulching on Growth and Yield of Rape

通过开展油菜旱作节水试验,对比湟中县油菜作物在不同颜色地膜种植时的效果,确定油菜地膜种植的最优模式,为今后推选出最佳地膜油菜生产模式奠定理论基础。试验结果,不覆膜(CK)、黑地膜、白地膜处理产量分别为4280.1kg/hm^(2)、4496.865kg/hm^(2)、4943.565kg/hm^(2),黑地膜、白地膜处理较不覆膜处理产量分别增加14.45kg、44.23kg,增幅为5.1%和15.5%。产量结果表明,不同的颜色地膜对油菜的产量具有明显的影响,白地膜对油菜增产效果较黑地膜大。

The experiment of water saving in dry cultivation of rape was carried out,compared the effects of different color plastic film on rape planting in Huangzhong County,the optimum pattern of rape plastic film planting was determined,which laid the theoretical foundation for selecting the optimum pattern of rape plastic film production in the future.The results showed that the yields of rape with no plastic film,black plastic film and white plastic film treatments were 4280.1kg/hm^(2),4496.865kg/hm^(2)and 4943.565kg/hm^(2)respectively,the yields of rape with black plastic film and white plastic film treatments increased by 14.45kg and 44.23kg respectively than those with no plastic film treatments,growth rate was 5.1 percent and 15.5 percent.This indicated that different color plastic film had obvious effect on rape yield,and white plastic film had greater effect on rape yield than black plastic film.
