摘要
通过不同镉含量土壤上的覆膜油菜微区试验,分析了覆膜和镉含量对油菜生长特性的影响。结果表明,覆膜和不覆膜的油菜株高、鲜物质量和干物质量均随着生长时间的延长而增大,生长相同时间,随着土壤镉含量的增高,油菜株高、鲜物质量和干物质量逐渐减小;在不同生长时间,覆膜处理的油菜株高、鲜物质量和干物质量均明显大于不覆膜处理,随着生长时间的延长,覆膜对油菜株高、鲜物质量和干物质量影响逐渐减小。
Though micro-plot trials of rape on different cadmium amount soil with film mulching,the growth characteristic of rape was analyzed.The result showed that plant height,fresh weight and dry weight of rape with film or without film increase gradually with time and decrease gradually with soil cadmium amount increasing;plant height,fresh weight and dry weight of rape under film mulching is obviously higher than rape without film mulching in different time;the effect of film mulching on rape plant height and fresh weight decrease gradually with time.
