摘要: 火龙果溃疡病是危害火龙果的重要病害之一.为有效开展火龙果溃疡病的生物防治,本研究比较了17种木霉菌的菌丝生长速率、产孢量,并通过对峙抑制试验和盆栽试验等比较不同木霉菌对火龙果溃疡病的抑制作用,从中筛选出了木霉菌KN-28,其抗生效果最强,其无菌发酵液对火龙果溃疡菌的抑制率高达92.9%,盆栽试验防效可达到59.07%~70.11%.综上所述,木霉菌KN-28防治火龙果溃疡病的潜力巨大,有望作为火龙果的生防目的菌株.

Abstract: Pitaya canker is an important disease to pitaya. In order to effectively carry out biological control of pitaya canker, the mycelial growth rate and spore yield of 17 Trichoderma species were accessed and their inhibitory effects on pitaya canker were compared by confrontation inhibition test and pot test. Trichoderma KN-28 had the highest antibacterial effect and the inhibition rate of its sterile fermentation broth to pitaya canker was as high as 92.9%. Pot experiment showed that the control effect of Trichoderma KN-28 could reach 59.07% to 70.11%. In conclusion, Trichoderma KN-28 has a great potential to control pitaya canker, and is expected to be the target strain for biological control of pitaya canker.
