采用草甘膦 + 1%无酶洗衣粉和草甘膦加柴油两种配比在不同浓度、剂量下的对比试验表明 ,两种配比在同一浓度下的防治效果基本一致 ,同一浓度下剂量越大 ,防治效果越显著。但从成本投入和防治效果综合考虑 ,草甘膦 +柴油 +水 ,浓度在 1∶ 1∶ 5和草甘膦 +水的浓度在 1∶ 1的剂量为 0 .1ml防治芦苇经济、有效 ,两种配制浓度及用量相同下防效都在 80 %以上 ,最好在芦苇生长旺盛期防治效果最好 ,3叶期株高 2 3cm时防效在 96%以上。
The comparison experiment of glyphosate + 1% enzyme-free detergent and glyphosate plus diesel at different concentrations and dosages showed that the control effect of the two ratios at the same concentration was basically the same, and the dosage under the same concentration The greater the effect of prevention and control more significant. However, considering the cost input and prevention and control effects, the dosage of glyphosate + diesel + water at a concentration of 1: 1: 5 and glyphosate + water at a ratio of 1: 1 is 0.1 ml, and the prevention and treatment of reed is economical and effective. The same concentration and dosage of the control effect are above 80%, preferably in the vigorous growth of Phragmites prophylaxis best effect, 3 leaf height 3 cm when the control effect of more than 96%.
