不同颜色地膜对火柴头后代生长的影响

Effect of different color of plastic films on offsprings' growth of Commelina bengalensis L.

为控制火柴头对农田产生的不良影响,探讨4种不同颜色地膜对3种类型火柴头种子后代生长的影响。结果表明:地膜颜色相同、不同类型的火柴头种子,其后代的生长与繁殖方式是不同的。种子类型相同,不同颜色地膜决定着植株的生长与繁殖方式。其中蓝色和黑色的地膜覆盖可最大程度地控制火柴头的生长。

In order to control the adverse effects of Commelina bengalensis L. on farmlands, four different color of plastic films were explored on the growth of three types of seeds of Commelina beng^densis L. The results showed that covering films of the same color, the growth and reproduction mode of the offspring were different using different types of seeds. Meanwhile, using the same type of seeds, films of different color determined the growth and reproduction of the plants. Among them, the effect of blue and black plastic films on limiting the growth of Commelina bengalensis L. were the best.
