| 摘 要： | 14C-苄嘧磺隆与尿素混用,处理后1h,陌上菜Lindernia procumbens (Krock.) Philcox]植株的14C放射性计数达到高峰.然而,14C-苄嘧磺隆单用,陌上菜植株的14C放射性计数随时间延长而缓慢增加,直至48h仍显著低于1h的除草剂与尿素混和的14C放射性计数.处理后24h,14C-苄嘧磺隆在陌上菜植株中的分配以根系最高,茎次之,叶最低.14C-苄嘧磺隆+尿素浸根,促进陌上菜植株对除草剂的吸收,但涂抹叶片时,无论单用还是混用,陌上菜植株均不吸收除草剂. |
| 关 键 词： | 苄嘧磺隆 尿素 陌上菜 除草剂 碳14 |

| Abstract: | Nutrient culture study was initiated to examine the synergistic mechanism of combinative application of bensulfuron and urea for weed control. The absorption of 14 C bensulfuron and their distribution in Lindernia procumbens (Krock.) Philcox were also investigated to determine the variation between two methods (combinative use of 14 C bensulfuron plus urea and 14 C bensulfuron alone). One hour after combinative application of 14 C bensulfuron plus urea, the highest amount of 14 C activity in L. procumbens were obtained. However, when 14 C bensulfuron applied alone, total absorption of 14 C activity was much lower in the 1st hour and then it slowly increased with time. The distribution of 14 C bensulfuron in root of L.procumbens plant was the highest and that in leaves was the lowest. |
