摘　　要：为了筛选出防除甜菜田间杂草理想的除草剂配方,进行了8种除草剂配方的甜菜田间杂草防除试验,结果表明,不同除草剂配方对甜菜田间杂草都有一定的防效,施用安全,且与产量和产糖量呈正相关,建议使用除草剂配方(5)(杂草2~4叶施用220m L/667m^2 16%甜安宁,杂草4~6叶施用260m L/667m^216%甜安宁+60m L/667m^2 20%乙呋黄,甜菜6~8叶施用280m L/667m^2 16%甜安宁+120m L/667m^220%乙呋黄)和除草剂配方(6)(杂草2~4叶施用260m L/667m^2 16%甜安宁,杂草4~6叶360m L/667m^216%甜安宁,甜菜6~8叶施用480m L/667m^2 16%甜安宁)对甜菜田进行除草。The test of 8 kinds of herbicide formulas to control sugarbeet field weed was conducted to screen ideal herbicide formula. The results showed that different herbicide formulas all had certain effect on controlling beet field weeds and were safety. They were positively correlated with root yield and sugar yield of sugarbeet. The recommended herbicide formulas were as follows： （1） Weeds 2 - 4 leaves, applying 220 mL/667m2 16% PhemediPham ＋ DesmediPham, Weeds 4 - 6 leaves applying 260 mL/667m2 16% PhemediPham ＋ DesmediPham ＋60 mL/667m2 20% Ethofumesate, beet 6 - 8 leaves applying 280 mL/667m2 16% PhemediPham ＋ DesmediPham ＋120 mL/667m2 20% Ethofumesate; （2）Weeds 2 - 4 leaves applying 260 mL/667m2 16% PhemediPham ＋ DesmediPham,Weeds 4 - 6 leaves applying 360 mL/667m2 16% PhemediPham＋DesmediPham, beet 6 - 8 leaves applying 480 mL/667m2 16% PhemediPham ＋ DesmediPham.
