森泰除草剂防除香椿幼林地杂草的试验研究

Experimental Study on Controlling Young Toona sinensis Forest Land Weeds with Hexazinone Herbicide

使用25%森泰水剂和5%森泰颗粒剂防除香椿幼林地的杂草研究试验结果表明:25%森泰水剂和5%森泰颗粒剂均能够有效防除香椿幼林地的五节芒、苦竹、刚竹、芒萁骨等多年生恶性杂草,防除效果均可达93%以上。使用25%森泰水剂除草比人工除草可减少用工56 1%～92 2%,降低除草成本36 1%～61%。同时,可根据幼林地杂草的种类、高度、盖度和水源等因素选择合适的森泰除草剂的剂型和剂量组合,以达到理想的防除杂草效果。

The experimental results indicated both 25% of hexazinone water agent and 5% of hexazinone granular pesticide could effectively control perennial malignant young Toona sinensis forest land weeds including Miscanthus floridulus,Pleioblastus amarus,Phyllostachys sulphurea and Dicranopteris linearis,etc.,the control effects all may reach 93% and more.Meanwhile,based on the species,height,cover degree and water source,etc.of young forest land weed,the suitable combination of drug form and drug dosage of hexazinone herbicide was selected to reach the rational effect of controlling weeds.
