摘要
利用0.11%对氯苯氧乙酸钠AS(2,4-滴)对番茄进行浸花处理试验,结果表明:在10,15,20mg/kg三个剂量下,具有提高番茄坐果率、促进番茄提早成熟、增加番茄早期产量的作用。但是在50mg/kg剂量下,番茄出现明显药害症状。施用时要根据气温适当调节施药浓度,并加强生长后期水肥管理。
Tomato flowers were dipped by 0.11% Sodium p-chlorophenoxy acetate AS in this research. The result showed it can increase fruit-setting rate, primary product, and promoted ripeness at 10,15,20 mg/kg （active ingredient）level, But there was symptom of serious chemical damage at the dose of 50 mg/kg （active ingredient）. So applied concentration must be pay attention, meanwhile temperature, water and fertilizer management should be enhanced.
