农药增效剂对多效唑的增效效果

Synergized Effect of Synergist of Pesticide for Paclobutrazol

在小麦分蘖期每亩用250ppm 的多效唑50kg 药液喷雾,可增产小麦26.13kg。若将每亩多效唑有效成份减少一半,再加入农药增效剂15ml,不但不会降低药效,且仍可增产小麦38.06kg。上述两种处理相比,后者比前者可多增产小麦11.93kg,经测验其差异达或显著水平;同时每亩还可降低生产费用2.36元。

Applying the Paclobutrazol of 250ppm,50kg per mu in the form of spray in the tiller stage,the output of wheat can be raised by 26.13 kg/mu. Decreasing the Paclobutrazol to 50%,and intercalated the synergist of pestici de to 15ml,the output of wheat can be raised by 38.06 kg/mu.The latter- treatment not only brings 11.93 kg more yield per mu than the former but also lowers the cost by 2.36 yuan per mu.
