- 摘要:
- 以番茄为试材，通过室内和田间对比试验，研究了竹醋液复合铜、氨基酸铜、络合铜A和络合铜B 4种不同的铜制剂对番茄软腐病的防治效果。结果表明：在室内条件下，每种铜制剂在供试浓度（1.25~20.00 mmol/L）内均对该病菌有一定的抑制作用，且抑菌效果随着浓度的升高而增强，且竹醋液复合铜的抑菌效果最好，其抑制中浓度（EC50值）为1.50 mmol/L；当竹醋液复合铜浓度为2.50 mmol/L时，对温室内番茄软腐病的治疗效果达到58.63%，而预防效果则高达77.72%，显著高于其它铜制剂的防治效果。
- Abstract:
- Taking tomato as material,the inhibition effect of bamboo vinegar reunited copper，compound amino acid cheated copper，cheated copper A and cheated copper B on bacterial soft rot of tomato were studied indoors and in the greenhouse.The results showed that the inhibition were strengthened with the increase of the concentrations by all copper treatments above，and the bacteriostasis of bamboo vinegar reunited copper was the best,with EC50 value 1.50 mmol/L.Therapeutic efficiency of bamboo vinegar reunited copper was 58.63% on bacterial soft rot of tomato in the greenhouse at the concentration of 2.50 mmol/L，which was significantly higher than the other copper preparations，while its preventative efficiency was up to 77.72%.
