研究黄腐酸钾与连作生物菌肥2种土壤修复剂对连作土壤西瓜枯萎病的防治效果。结果表明,单施或混施上述土壤修复剂后,各处理对西瓜枯萎病的相对防效都在38.6%以上,较对照可增产9.7%以上。尤以连作和黄腐酸钾混用处理对西瓜枯萎病的防效最高,相对防效可达63.9%,增产35.2%。综合考虑防治效果与使用成本,建议混合连作和黄腐酸钾作为防治连作土壤西瓜枯萎病的土壤修复剂。
The effects of two soil remediation agents such as potassium fulvate and continuous cropping bacterial fertilizer on water and fusarium wilt of continuous cropping soil were studied. The results showed that the relative control effects of all the treatments on watermelon blight were over 38.6% after single application or mixed application of the above soil remediation agents, which could increase 9.7% or more compared with the control. Especially in continuous cropping and yellow fulvic potassium mixed treatment of watermelon blight the highest control effect, the relative control effect of up to 63.9%, an increase of 35.2%. Considering the effect of prevention and treatment and the cost of using, we suggest that mixed continuous cropping and potassium fulvic acid should be used as soil remediation agent for the prevention and control of soil watermelon wilt.
