不同除草剂对甘薯田间杂草的防除效果

Control Effect of Different Herbicides on Weeds in Sweet Potato Field

为缓解甘薯种植过程中除草成本过高的问题,筛选出薯标、精喹禾灵、氟吡甲禾灵3种除草剂进行甘薯生长发育及田间杂草防除效果的试验。结果表明,相比于其他除草剂,薯标处理的杂草株数和杂草鲜质量显著降低,杂草株防效和鲜质量防效显著增加,薯标除草效果最佳,与对照相比,薯标处理的分枝数、单株结薯数分别增加26.09%,23.27%,蔓长显著降低27.78%,鲜薯产量增加31.18%;精喹禾灵处理的商品薯和大中薯产量最低,小薯产量最高。综合杂草防控和甘薯性状,在商薯19生产过程中喷施2250 mL/hm^2薯标除草剂较为适宜。

To alleviate the problem of labor difficulties and high cost in the process of sweet potato cultivation,the field experiments were conducted to study the effects of three herbicides on the weeds control and growth and development of sweet potato.The results showed that the number of weeds and fresh quality of weeds treated by Shubiao decreased significantly compared with other treatments.The control effect of weed plants and fresh quality significantly increased,and the weeding effect of Shubiao was the best.Compared with CK,branch number and tuber number of per plant of potato label increased by 26.09%,23.27%,respectively,vine length decreased by 27.78%,the yield of fresh potato increased by 31.18%.The yield of commercial potatoes and large and medium sweet potatoes was the lowest,and the yield of small potatoes was the highest of Quizalofop-P.Comprehensive weed control and sweet potato characters,sprayed the sweet Shubiao herbicide was more suitable for production of Shangshu 19.
