摘要
由尖孢镰刀菌古巴专化型引起的香蕉枯萎病,是目前香蕉产业发展中的限制因子,采用生物防治的方法是目前非常有潜力的防控手段。生防微生物的效果主要与土壤水分、作为活菌制剂的微生物种类和性质、生防微生物在土壤中短期定殖影响因素、生防微生物长期定殖影响因素有关。采用茎叶滴注的方法进行香蕉内生芽胞杆菌接种或辅以适当的载体,和保水微生物一起混合接种到香蕉根围,可以有效防控香蕉枯萎病。
The Fusarium wilt of banana caused by Fusarium oxyspoum f. sp. cubense （Foc） is a major biotic limited factor for the present banana production. Bio-control of the disease is an effective way to reduce the loss. Control Effect of the potential bio-control agent is mainly affected by soil moisture content, characteristics of the microorganism, long-term colonization affecting factors and shot-term colonization affecting factors. To control the Fusarium wilt of banana, two selective ways are suggested. One is inoculating the endophytic microorganism of Bacillus sp. into the stem of banana. The other is mixed-inoculating the endophytic microorganism of Bacillus sp. and water-keeping microbial agents into the rhizosphere of banana
