| 摘 要： | 目的]研究几种不同作用机理的防线虫制剂对植株叶片酶系统及膜透性的变化,为设施菜田土壤根结线虫的有效防治提供参考依据。方法]以根结线虫侵染后的番茄幼苗为材料,在无线美、海绿素、毒线丹和阿维菌素等制剂处理幼苗土壤后,测定了番茄体内SOD、POD、相对电导率和MDA含量及变化。结果]经施用不同制剂后,番茄叶片的SOD和POD酶活性高于对照,在4种药剂中以无线美最高。除毒线丹制剂外,其他处理的相对电导率和MDA含量均显著低于对照。番茄种植70 d后,阿维菌素防治根结线虫的效果最好,达66.3%。结论]根结线虫侵染番茄后,经不同药剂处理均有一定的防效,且使番茄的生理指标有了明显变化。设施菜田采用多种制剂综合防治有利于土壤根结线虫的控制。
