摘  要:为了明确河西走廊辣椒根腐病发病因素与发病程度的相关性,研究不同品种、不同药剂蘸根、不同药剂灌根、不同连作方式以及不同定植时间等因素对辣椒根腐病发生的影响。结果表明,各因素与辣椒根腐病发病程度具有极显著相关性(P<0.01)。‘陇椒5号’抗病性最强,恶霉灵+适乐时(70%恶霉灵WP+适乐时2.5%咯菌啨FS)混合蘸根防治效果较好,世高+恶霉灵(10%苯醚甲环唑WDG+70%恶霉灵WP)混合灌根效果最明显,新建温室发病率大幅度降低,9月20日及以后定植的辣椒发病率较低。In order to make clear the in Hexi Corridor of Gansu Province, correlation between the influence factors and disease severity of capsicum root rot we have studied the effects of different varieties, different chemical dipping root treatments, root irrigation of different agents, different cropping patterns and different planting time on capsicum root rot. The results showed that incidence of capsicum root rot and five different treatments have a very significant correlation (P〈0.01). Longjiao No.5 had the strongest resistance. The dipping root treatment with hymexazol and fludioxonil (70% hymexazol WP and 2.5% fludioxonil FS) got the better effect. The root irrigation treatment with Shigao and hymexazol (10% Difenoconazole WDG and 70% hymexazol WP) got the most obvious effect. The incidence rate in newly-buih greenhouse reduced greatly, and the incidence rate was low from mid-September to mid-October.
