果园杂草种类繁多,繁衍迅速,人工除灭费工费时,且难以彻底。近年来,草甘膦作为果园除草剂应用已有报道。其优点是:高效低毒,内吸性强,杀草范围广,土壤无残留。但其药效迟缓,一般7天后见效,对宿根性杂草效果尤差。为增强其药效,缩短药效发挥时间,我们在本校果园内进行了草甘膦+乙烯利化学除草增效试验。 Orchard weeds a wide range, rapid reproduction, labor costs and labor costs, and difficult to completely. In recent years, glyphosate has been reported as an orchard herbicide. Its advantages are: high efficiency and low toxicity, strong absorption, a wide range of herbicide, soil no residue. However, its efficacy is slow, usually effective after 7 days, the effect of perennial weeds particularly poor. In order to enhance its efficacy and shorten the time to exert its efficacy, we conducted a glyphosate + ethephon herbicidal and synergistic experiment in our school orchard.
