在冬麦田应用百草敌防除阔叶杂草的试验示范结果表明 ,1hm2用 48%百草敌水剂 2 2 5ml,30 0 ml,375 ml,对水 675 kg/ hm2 ,在 3月 2 5日 (冬小麦拔节前 10天左右 )喷雾进行茎叶处理。 2 0天后 ,对各种杂草的防除效果 ,灰黎为 88.4% ,89.5 %及 93.7% ;播娘蒿为 66%及82 .9%和 85 .1% ;米瓦罐为 5 0 % ,66.7%及 83.3% ;田旋花为 77.8% ,88.9%及 88.9% ;苦苣为 38.9% ,77.8%及 67% ;涩荠为 46.2 % ,61.5 %及 69.5 %。综合分析 ,以用量 30 0 ml/ hm2 为好。大田示范用量 30 0 ml/ hm2 ,对播娘蒿、灰藜、田旋花防效分别为 82 .5 % ,86.4%及 74.3% ,增产效果为 2 1.4% ,成本低于 2 .4D丁酸和 2甲 4氯 ,对小麦安全。 In the winter wheat field trial of herbicide against broadleaf weeds showed that 1hm2 was treated with 48% Herba Albatrosus, 250ml, 300ml, 375ml, 675kg / hm2 of water on March 25 Winter wheat before jointing about 10 days) spray for stems and leaves treatment. After 20 days, the control effect on various weeds was 88.4%, 89.5% and 93.7% respectively, that of Artemisia annua was 66%, 82.9% and 85.1% 66.7% and 83.3% respectively. The spikes were 77.8%, 88.9% and 88.9% respectively. The bitter chrysanthemums were 38.9%, 77.8% and 67% respectively. The water chestnuts were 46.2%, 61.5% and 69.5% respectively. Comprehensive analysis, the amount of 30 0 ml / hm2 is better. The field dosage of 30 0 ml / hm2 was 82.5%, 86.4% and 74.3% for Artemisia annua L., Chenopodium glaucum, and Spinosia, respectively, with a yield increase of 214.4% and a cost of less than 2.4D butyric acid And 2 A 4 chlorine, safe for wheat.
