摘  要：
为了筛选能有效控制野荸荠球茎的除草剂,采用茎叶处理的方法,研究9种除草剂单剂或混剂对桶栽野荸荠球茎形成的控制效果。结果表明,吡嘧.唑草酮有效成分用量54、67.5g/hm2处理后野荸荠球茎的形成完全受到抑制,吡嘧磺隆45、52.5g/hm2处理对野荸荠的球茎数量的抑制率达100%、97.30%,球茎产量的抑制率达100%、98.35%,2甲4氯钠756、924g/hm2对野荸荠球茎数量的抑制率也达95.04%、99.43%,球茎产量的抑制率达95.68%、99.62%,这些药剂处理后球茎大小也显著小于对照;苄嘧.唑草酮57、68.4g/hm2也对野荸荠球茎数量有较好的抑制作用,对其产量的抑制率则较高,球茎大小也显著小于对照;而氯氟吡氧乙酸、2甲4氯.氯氟吡氧乙酸、灭草松和唑草酮对野荸荠球茎数量、产量及球茎大小的影响小。

摘  要：
The suppressions,exerted by nine kinds of herbicides with foliar-treatment,on corm formation of E.plantagineiformis were tested in plastic keg naturally,for screening herbicide to control corm of E.plantagineiformis.The results showed that,the number of E.plantagineiformis corm was completely suppressed by pyrazosulfuron.carfentrazone-ethyl with an active ingredient dose of 54 g/hm 2 and of 67.5 g/hm 2.When dose of pyrazosulfuron was 45,52.5 g/hm 2,the inhibitory percentage nearly amounted to 100%.Being treated by MCPA-sodium with an active ingredient dose of 756,924 g/hm 2,the inhibitory percentage was 95.04%,99.43% in number and 95.68%,99.62% in yield.There was lower suppression in corm number,and efficient inhibition in yield and size after being treated by bensulfuron-methyl.carfentrazone-ethyl at 57 g/hm 2 and 68.4 g/hm 2.However,there were small effects on the number,yield and size of E.plantagineiformis corm which had been treated by other tested herbicides involving fluroxypyr,bentazone and carfentrazone-ethyl.
