在人工气候室试验了添加剂硫酸铵对镇草宁的增效作用,初步研究了不同环境条件对添加剂硫酸铵活化作用的影响。 0.1～1.0％硫酸铵不仅对镇草宁防除狗牙根地上部的药效,具有显著的增效作用,而且也可使狗牙根地下根茎的复发能力大为降低。处理狗牙根地上部的镇草宁浓度意低,硫酸铵的增效作用愈显著,随着镇草宁浓度的增加,增效的坡度渐低而最后趋于接近。由于硫酸铵的增效作用,镇草宁的使用剂量可减少一半左右。 环境条件对硫酸铵的活化作用没有影响,在各种环境条件下,硫酸铵对镇草宁的增效作用基本相同。
The synergistic effect of additive ammonium sulphate on Zhencao Ning was tested in the artificial climate chamber, and the effect of different environmental conditions on the activation of the additive ammonium sulphate was preliminary studied. 0.1-1.0% ammonium sulfate has significant synergistic effect not only on the effect of Zhencao Ning against the proliferation of bermudagrass, but also greatly reduces the germination ability of root rhizomes of Bermudagrass. The treatment of bermudagrass of the town grass Ning Italy concentration Italy, ammonium sulfate synergistic effect of the more significant, with the town grass Ning concentration increases, the efficiency of the slope gradually decreased and eventually tends to close. Because of the synergistic effect of ammonium sulfate, the use of Zhencao Ning dose can be reduced by about half. Environmental conditions have no effect on the activation of ammonium sulfate. Under various environmental conditions, the synergistic effect of ammonium sulfate on Zhencao Ning is basically the same.
