| 为了解花生田除草剂甲咪唑烟酸残留对后茬不同种类蔬菜的药害风险，田间评价了甲咪唑
烟酸在有效成分用量为108 g /hm2 后对下茬13 种蔬菜生长的影响，结果表明：甲咪唑烟酸土壤残留对后
茬瓜菜（青瓜、节瓜、白瓜）和叶菜（菜心、芥蓝、芥菜、红苋菜）幼苗生长抑制作用均达到极显著水平
（P<0.001），株高、根长和鲜重抑制率达到31%～95%；对不同茄科蔬菜（茄子、番茄、辣椒、马铃薯）、豆
角及其不同部位的抑制作用有差异；对甜玉米根长和株高的抑制作用与对照组相比无显著差异。用土壤添
加法进一步的室内生测结果表明，青瓜、菜心、辣椒和豆角对甲咪唑烟酸十分敏感性，按根长和株高的ID50
和ID10 值由低至高排列对甲咪唑烟酸敏感性，结果均显示：青瓜> 菜心> 辣椒> 豆角，且不同部位的ID50
和ID10 均显示根系比株高更敏感。因此，在蔬菜种植区，特别是后茬种植瓜菜和叶菜的田块不能使用甲咪
唑烟酸。 |
| 英文摘要: |
| In order to study the effects of imazapic residue on growth of vegetables，experiments were conducted
by growing 13 kinds of vegetables succeeding to the field with initial imazapic dosage of 108 g/hm2. The results
showed that imazapic residue obviously affected cucurbitaceous vegetables（ cucumber，Zucchini，white melon） and
leaf vegetables（flowering Chinese cabbage，cabbage mustard，senvy，red spinach）. The inhibition rate of their
plant height，root length and upside fresh weight varied from 31% to 95%，which was significant. As for Solanaceous
vegetables（ eggplant，tomato，pepper and potato） and long bean，the inhibition effect varied for different vegetables
and different parts of the vegetables；the root length and plant height for sweet corn did not have significant difference
compared to control group. Moreover，4 kinds of vegetables were grown in lab with modeling imazapic residue dosage
from 0 to 96μg/kg. By comparing their ID50 and ID10 value for plant height and root length，we can conclude the order
of sensitivity to imazapic: cucumber > flowering Chinese cabbage > pepper > bean；ID50 and ID10 value also showed
that roots were more sensitive than stem. Therefore，it is not recommended to use imazapic if succeeding corps are
leaf vegetables and cucurbitaceous vegetables. |
