摘要
[目的]筛选出适用于火龙果园的除草剂品种。[方法]采用喷雾法,测定不同除草剂对火龙果的安全性及对牛筋草的除草活性。[结果]常用量处理30 d,精喹禾灵和高效氟吡甲禾灵对火龙果茎、根抑制率低于5%,对牛筋草鲜重防效大于90%;草甘膦对火龙果根长抑制率达50%,对牛筋草防效低于70%,其他试验药剂对火龙果幼茎生长有显著抑制作用。[结论]精喹禾灵和高效氟吡甲禾灵对火龙果安全,适用于火龙果园牛筋草的防除。
[Aims] The study aims to screen out herbicides applied to Hylocereus undulatus orchards. [Methods] The selectivity of different herbicides to H. undulatus and their weeding efficacy on Eleusine indica were evaluated by foliar spraying method. [Results] At 30 th day, the inhibition rates of quizalofop-p-ethyl and haloxyfop-p-methyl treated with usual doses on H. undulatus stem and root were less than 5%, and their fresh weight control effects on E. indica were more than 90% at the same time, root length inhibition rate of glyphosate isopropylamine to H. undulatus was more than 50%, as well as its control effect on E. indica were less than 70%, other experimental herbicides had a significant inhibitory effect on young stem growth of H. undulatus. [Conclusions] Quizalofop-p-ethyl and haloxyfop-p-methyl were safe to H. undulatus at test dose, which would be suitable for E. indica control in H. undulatus orchards.
