摘　　要：研究了甲磺隆对水稻不同品种的抑制作用 ,结果表明 :⑴甲磺隆对水稻不同品种抑制作用存在较大差异 ,表现为对早稻的抑制作用大于晚稻 ,对常规稻的抑制作用大于杂交稻。⑵甲磺隆对水稻根长、株高的抑制作用十分类似 ,甲磺隆的浓度对数与水稻根长。Effects of inhibition of metsulfuron-methyl to different rice varieties were studied.The results were as follow.⑴There were significant differences among different rice varieties due to the effects of metsulfuron-methyl.The effect of inhibition to early rice was stronger to normal rice,and it was stronger than that to hybrid rice;⑵ The effects of inhibition of metsulfuron-methyl to root length and plant height of rice were similar,and there was asymmetric S-curve relation between the logarithm density of metsulfuron-methyl and both root length and plant height of rice.
