覆膜处理对恩施地区超稀植模式种植油菜的影响

Effects of Plastic Film Mulching on Rape Planting Under Super Sparse Planting Pattern in Enshi

采用每平方种植1株油菜(Brassica napus L.)的超稀植模式种植油菜并进行覆膜处理,可适当提升油菜的株高,提升抗倒伏能力,对油菜冠幅、分枝角度、茎粗等性状没有明显影响。但覆膜种植油菜对油菜子品质有一定的负面影响,覆膜种植后,油菜子中芥酸含量、硫代葡萄糖苷含量、蛋白质含量都有所升高,含油率下降。综合分析认为,超稀植模式下覆膜种植油菜不是较好的种植方式。

The height of plant and the lodging resistance of rapeseed can be improved appropriately,and the crown width,branch angle and stem diameter of rape be not significantly affected when the rape was planted in super sparse planting pattern of 1 plants per m2,and covered with plastic film.Planting rape on rapeseed has a negative effect on rapeseed quality.The content of erucic acid,glucosinolates and protein content of rapeseed increased,and the oil content decreased.It showed that under the super sparse planting pattern,rape planting was not the best way of planting by comprehensive analysis.
