- 摘要:
- 以根结线虫侵染后的黄瓜幼苗为试材，用无线美、海绿素、毒线丹、阿维菌素处理种植土壤后，测定了黄瓜叶绿素、SOD、POD、相对电导率含量的变化，检测药剂对线虫的防治效果。结果表明：经药剂处理后，黄瓜叶部的SOD活性高于对照，在4种药剂中以无线美的最高；处理的POD活性均显著高于对照，其中无线美处理值是对照的3倍多；药剂处理的相对电导率均显著低于对照。根结线虫侵染番茄后，经不同药剂处理均有一定的防效，且使黄瓜的生理指标有明显变化。
- Abstract:
- Cucumbers infected by Meloidogyne spp. as material in this experiment, changes of superoxide dismutase(SOD),peroxidase(POD),relative conductivity in cucumber were tested, in order to reflect control effect of different pesticides to Meloidogyne spp.,when the soil was respectively treated by Wuxianmei, Hailvsu,Duxiandna and Avermectin.The results showed that SOD activity of cucumber leaves in the treatment was higher than that in the control.SOD activity of cucumber treated by Wuxianmei was highest in four pesticides.POD activity in the treatment was all obviously higher than that in the control. Treatment value of Wuxianmei was more than three times of control value.Relative conductivity in the treatment except Duxiandan were obviously higher than those in the control.Different pesticides had some certain effect to Meloidogyne spp. infecting cucumber and made cucumber physical indexes had distinct change.
