摘  要：
文章采用室外盆栽法研究野慈姑球茎发生规律和化学控制技术,探讨野慈姑防除方法。研究表明,球茎繁殖野慈姑结球盛期在8月中旬~9月中上旬。当抽薹数为6个·株-1时,发生新球茎概率最大为83.00%;种子繁殖野慈姑结球盛期在8月末到9月中上旬。当抽薹数为3个·株-1时,发生新球茎概率最大为66.70%;五氟磺草胺土壤处理对当年野慈姑球茎抑制效果最好,丙嗪嘧磺隆对次年球茎出苗控制最好。茎叶处理对野慈姑球茎抑制作用顺序依次为氯氟吡啶酯>2-甲-4-氯钠盐>2-甲·灭草松>嘧肟·丙草胺>灭草松。文章填补国内野慈姑球茎防除效果研究空白,为多年生杂草营养繁殖器官防除提供参考。

摘  要：
Study on the outdoor potted plant method occurrence and chemical control technology of Sagittaria trifolia L. corms were targeted by pot method, and then the master not only reduced the Sagittaria trifolia L. on the competitiveness of rice, but also reduced the occurring number of the next year Sagittaria trifolia L. The results were as follows: new corms occurred Sagittaria trifolia L. peaked from mid-August to early September. When the number of bolting was six per plant, the probability of new corms occurred was 83.00% at the maximum. The seed propagation of Sagittaria trifolia L. peaked from late August to early September. When the number of bolting number was three per plant, the maximum probability of occurrence of new bulbs was 66.70%. Soil treatment Herbicide: Penoxsulam had the best inhibitory effect on the corm seedlings. Propyrisulfuron was the best control of the emergence of the next year corms. The order of inhibition of the leaf-treated herbicides of the corms was as follows: florpyrauxifen-benzyl> agritox >agritoxbentazone> pyribenzoxim-pretilachlor >bentazon. The results obtained in this study could fill the gaps in the research on Sagittaria trifolia L. corms control effect, and provide a reference method for control of reproductive organs of perennial weeds.
