摘  要:
利用已经筛选的耐豆磺隆甜菜品系,研究豆磺隆土壤和茎叶处理对甜菜生物性状的影响。结果表明,土壤中豆磺隆施用量为0.5 ga.i..hm-2时对耐性甜菜品系生长无明显抑制作用。当土壤中豆磺隆施用量为0.5和1.0ga.i..hm-2时,耐性甜菜品系根系活力降幅较小,叶绿素含量呈增加趋势。用7.5 ga.i..hm-2豆磺隆茎叶处理3 d后,耐性甜菜品系叶绿素含量开始增加,并且在短时间内恢复至正常水平,叶片鲜重虽然受到一定抑制,但6 d后开始恢复生长,根系则保持持续增重。

摘  要:
Using tolerant sugarbeet to chlorimuron-ethyl which has been selected in our laboratory to study its biological character as chlorimuron-etyl was used in soil and sprayed on leaf.The results showed that growth of the tolerant sugarbeet variety was unaffected when soil chlorimuron-ethyl was 0.5 ga.i.·hm-2.Root activity of tolerant variety was slightly decreased and chlorophyll content showed increasing trend when soil chlorimuron-ethyl was 0.5 and 1.0 ga.i.·hm-2.Three days after 7.5 ga.i.·hm-2 chlorimuron-ethyl was sprayed on the leaf of tolerant sugarbeet,its chlorophyll content began increased and recovered formal level in short time.Although fresh weight of leaves was inhabited,but it recovered growth after 6 d.The root weight maintained formal growth all the time.
