摘　　要：使用不同孔径WS-16型背负式手动喷雾器喷片喷雾防除胡麻田一年生阔叶杂草和野燕麦的结果表明,药液在胡麻叶片上的附着率以0.7 mm喷片孔径最高。药后45 d 40%2甲.辛酰溴乳油1 500 mL/hm2对水675kg对一年生阔叶杂草的防效、8.8%精喹禾灵乳油750 mL/hm2对水675 kg对野燕麦的防效均以0.7 mm孔径喷雾最高,不同孔径之间差异极显著。The different diameters apertures of WS-16 hand-operated knapsack against annual broadleaf weeds and wild oat （Avenafatua L.） was studied in linseed field. The results showed that the highest adhesive rates was 0.7 mm. After 45 days the Control effects on annual broadleaf weed by using 40% MCPA-Isooctyl Bromoxynil Octanoate EC with 1 500 mL/hm2 and wild oat by using 8.8% Quizalofop-P-ethyl EC with 750 mL/hm2 in linseed field were significantly different by using different diameters aoertures, but the best were 0.7 mm.
