摘要
利用13种除草剂对棚栽香附子进行芽后茎叶喷雾药效对比试验,并对药效较好的除草剂进行了安全性评价。结果表明,在试验条件下,豆磺隆、甲磺草胺、太阳星、灭草松、2甲4氯在剂量较高时药效较好,达75%以上;宝成、秀百宫、百垄通等对香附子的防治效果最好,达90%以上,且能杀灭再生根茎。在防效最好的除草剂中,秀百宫的药害较轻,宝成的药害较重。百垄通的药害最重,使甘蔗难以恢复生长。一些混用的组合表现较高的选择性。
The effect of 13 herbicides on control of weed Cyperus rotundus L. , which planted in shed covered with plastic film, was conducted by spraying on the leaves of the plant. And the safety to the crop was evaluated in some of the herbicides those showed high control effect in sugarcane field. The result showed that with the tested condition, chorimuron -ethyl, sulfentrazone, ethoxysulfuron, bentaxone and MCPA gave a better control effects,topping 75%, but with the effects over 90%, rimsulfuron, flazasulfuron and imazapic gave the best ones compared with the others. Furthermore they could effectively kill the regenerated bulb of the weed. In poisonous effect on sugarcane, rimsulfuron was more serious than flazasulfuron, while imazapic was the most serious, which caused so badly injury to the crop that the poisoned plants couldn＇t return to normale. Some mixtures of the herbicides performed a highly selectivity in controlling the weed.
