采用 5 0 %骠·异隆 375 g/ hm2、 5 6 2 .5 g/ hm2、 75 0 g/ hm2三个剂量 ,在整地质量好的麦田施药后 40 d对碎米荠的密度防效均达 10 0 % ;施药后 80 d对看麦娘密度防效分别为 86 .0 2 %、 90 .90 %及 93.43% ,鲜重防效分别为 95 .11%、 96 .77%、 97.96 % ;对牛繁缕的密度防效和鲜重防效均达 10 0 %。在整地质量差的试验田防除效果比整地精细的效果差。施用该药剂防除麦田杂草有增产作用 ,增产率分别为 19.40 %、 2 3.83%及 2 2 .11%。
The density of M. cardamom was controlled 40 days after the application of three different dosages of 50% 骠 and IU 375 g / hm2, 562.5 g / hm2 and 75 0 g / hm2 Reaching 100%. After 80 days, the control effect on the density of Ophiopogon japonicus was 86.02%, 90.90% and 93.43%, respectively. The fresh weight and anti-control efficiencies were 95.11% and 96.77%, respectively. 97.96%; the control effect on the density and the control of the fresh weight of the calf are all up to 100%. In the preparation site of poor quality test preparation, the effect of prevention and cure is worse than the fineness of site preparation. The application of the medicament to control the weeds in wheat field has the effect of increasing yield, the increment rates are respectively 19.40%, 23.83% and 22.11%.
