摘要：

本研究通过对杭州地区收集的3种地方特色白黄瓜种质资源的病虫害发生情况进行调查,分析了其对主要病虫害的易感性,研究了不同种质资源的病虫侵害风险并制定了其防治技术。结果表明,在田间自然发生条件下,苗期病害以2022CA1-1最易感;大田期的病害以黄瓜霜霉病最为易感,其中2022CA1-2对霜霉病感病性最强,春黄瓜、秋黄瓜上病情指数峰值分别达77.89、80.04;细菌性角斑病2022CA1-1和2022CA1-2均中度易感,易感性高于2022LH1-1;白粉病在生长中后期发病重,以2022CA1-2最易感;虫害以蚜虫、烟粉虱、蓟马等微小害虫最易感,瓜绢螟中度易感,美洲斑潜蝇、红蜘蛛等其他害虫在田间时有查见但虫量不高,各种质间主要害虫发生程度差异均不显著。根据不同种质资源病虫害易感性情况分析,针对播种前、苗期、大田期不同时期发生的病虫害制定了绿色防控技术,以期为白黄瓜抗病虫种质材料的筛选及利用提供依据。

Abstract:

In this study, we investigated the occurrence of pests and diseases of 3 local varieties of white cucumber germplasm resources collected from Hangzhou area, analyzed their susceptibility to diseases and pests, explored the disease and pest risk and developed the control technique for them. The results showed that under the condition of natural occurrence, different germplasms of white cucumbers have significant differences in the susceptibility to diseases and pests. The most susceptible germplasm to seedling disease was 2022CA1-1. Downy mildew was the most susceptible disease in the field period, and the most susceptible germplasm was 2022CA1-2 whose peak disease index of spring and autumn cucumber were 77.89 and 80.04, respectively. The susceptibility of 2022CA1-1 and 2022CA1-2 to the bacterial angular leaf spot were moderate which showed higher than 2022LH1-1. The most susceptible germplasm to powdery mildew was 2022CA1-2 which led to heavy occurrence in the middle and late growth stage. Aphis gossypii, Bemisia tabaci, Thrips palmi were the most susceptible pests, and Diaphania indica was moderate. Liriomyza sativae and Tetranychus cinnbarinus could be often investigated but less amount of occurrence. The incidence extent of all major pests had no obvious difference between different germplasms of white cucumber. On the basis of susceptibility analysis results to pests and diseases in various germplasm, the green techniques against different stages which included preplanting, seedling and field period were formulated. The findings of this study could be useful for breeding and utilization of resistance germplasm in white cucumber.
