摘　　要：为明确宛氏拟青霉提取物(ZNC)对番茄根结线虫病的防治潜力,采用盆栽试验,以清水为对照,研究ZNC(0.5、1.0μg·株-1灌根)、阿维菌素(5 mg·株-1底施处理)及两者配施对番茄生长和果实品质的影响及其对根结线虫病的防治效果。结果显示,与清水处理相比,ZNC能够显著提高番茄根质量,降低根结数量,同时能够显著增加番茄的叶长、叶宽,提高番茄的株高和地上部鲜质量,还可提升植株抗氧化能力和果实品质;与阿维菌素配施对番茄根结线虫病防效可达88.89%,显著高于阿维菌素单施,同时番茄生长状况和果实品质得到提升。表明ZNC能够促进番茄生长,与阿维菌素配施后可提高番茄根结线虫病的防治效果。In order to determine the control potential of Paecilomyces variotii extract named ZNC against tomato root-knot nematode disease,this paper conducted pot culture experiment and took water as the contrast to study the effects of applying ZNC(root-irrigation:0.5 or 1.0μg per plant),abamectin(basal application:5 mg per plant)and their combinations on tomato growth and fruit quality,their control effects on root-knot nematode disease,respectively.The results showed that comparing with water treatment,ZNC could significantly increase tomato root fresh weight and reduce root nodes number,at the same time significantly increase tomato leaf length and width,raise tomato plant height,above ground fresh weight,and promote plant antioxidant capacity and fruit quality.The control effect of ZNC combined with abamectin against tomato root-knot nematode disease could reach 88.89%,significantly higher than that of applying abamectin alone.Meanwhile,tomato growth conditions and fruit quality were all got promoted.These facts indicated that ZNC could promote tomato growth,improve control effect against tomato root-knot nematode disease when combined with abamectin.
