摘要
室内测定了环境因素与油乳剂对莠去津防除杂草的影响．结果表明，土壤含水量、空气湿度的提高均有利于莠去津茎叶处理药效的发挥，而４８ｈ内降雨将大大降低莠去津的防效．莠去津喷雾液内加入油乳剂将减轻上述不利因素的影响，提高莠去津的喷雾效果。
Experiments were conducted in the growth chamber and greenhouse to determine the influence of relative humidity,soil moisture content (SMC),simulated rainfull,and oil additive with atrazine upon weed control.Generally,atrazine increased the effectof weed control with high rather than low relative humidity and low SMC.A simulatived rainfull within 48h after atrazine application greatly reduced weed control efficiency.Oil Emulsion to the spray heavily reduced the edtrimental effect of above envir onments.
