| 摘 要： | 研究了甜瓜枯萎病菌的生物学特性，并对防治药剂进行了室内初步筛选。结果表明：菌丝生长的适宜温度范围为5～35℃，最适温度30℃，菌丝和孢子的致死温度为58℃；光暗交替条件下产孢量最大。生理生化特性测定结果表明：甜瓜枯萎病菌对孔雀石绿不敏感，对淀粉和硝态氮的利用能力强。采用生长速率法测定了9种杀菌剂对病菌的抑制作用，其中多菌灵和氟硅唑的毒力较高，EC30分别为2．2671mg／L和13．3418mg／L。 |

| Abstract: | The biological characteristics of muskmelon fusarium pathogen were studied and the preliminary screening of fungicides was conducted in a laboratory.The results showed that the suitable temperature for the mycelial growth was 5～35 ℃ and the best was 30 ℃.The thermal death temperature of the mycelia and conidia was 58 ℃.Alternation of light and dark could promote the spore production.The tests for the biochemical characteristics showed that Fusarium oxysporum(Schl.)f.sp.melonis was insensitive to malachite green and could utilize starch and nitrate nitrogen.The tests for the inhibiting effects of 9 fungicides on F.oxysporum f.sp.melonis indicated that carbendazim and flusilazole were the highest in toxicity and their EC_(50) was 2.2671 mg/L and 13.3418 mg/L,respectively. |
