摘　　要：试验采用喷雾法初步研究蜡质芽孢杆菌3BY4和阿氏肠杆菌BQ9对番茄黄化曲叶病毒病的防病增产作用。温室试验结果表明,3BY4和BQ9对该病毒病的防治效果分别为58.19%和52.77%。江苏赣榆田间试验表明,3BY4和BQ9对番茄黄化曲叶病毒病的防治效果分别为47.03%和42.76%。同时,研究了3BY4和BQ9对番茄产量和品质的影响。结果表明,3BY4和BQ9对番茄的增产率分别为21.32%和26.14%,而且能够显著提高番茄果实中维生素C、可溶性糖和可溶性蛋白的含量,降低有机酸的含量。北京郊区田间试验表明,3BY4和BQ9对‘欧盾’的防治效果在44%以上,对‘中农105’和‘Moneymaker’的防治效果不显著在17%~30%之间,表现出品种差异性。综上所述,生防菌3BY4和BQ9对番茄黄化曲叶病毒病均表现出一定的防病增产效果,且能够改善番茄品质,具有广阔的应用前景。The effects of biological agents 3BY4 and BQ9 on resistance to tomato yellow leaf curl virus disease and on yield-promoting by spray were studied. Greenhouse test showed that 3BY4 and BQ9 provided significantly control efficacy, with rates of 58.19% and 52.77% respectively. The control efficacy of 3BY4 and BQ9 to tomato yellow leaf curl virus reached 47.03% and 42.76%, respectively, under field conditions in Ganyu. Furthermore, the effects of strains 3BY4 and BQ9 on the yield and quality of tomato in fields were investigated. The yields were increased by 21.32% and 26.13% after application of 3BY4 and BQ9 respectively and they could also improve the tomato quality by increasing the contents of vitamin C, soluble sugar, soluble protein and decreasing the content of organic acid. The field test in Beijing suburban area resulted that the control efficacy after treatment with the agents to ＇Oudun＇ was over 44%, but 17%-30% to ＇Zhongnong 105＇ and ＇Moneymaker＇, showing breeds variability. Our results suggest that 3BY4 and BQ9 had good effect against tomato yellow leaf curl virus and on yield-promoting and would have a broad application prospect in the future.
