【摘要】 为了有效防控甘肃温室黄瓜枯萎病,获得生防效果较好的高效拮抗菌株,从甘肃武威市凉州区日光温室大棚黄瓜枯萎病根际土分离多株菌株,通过平板拮抗试验、室内盆栽效果试验,得到1株对尖孢镰刀菌(Fuasrium oxypsorum)有较强抑制作用的假单胞属菌株33-1,经鉴定33-1为弗雷德里克斯堡假单胞菌(Pseudomonas frederiksbergensisi)。结果表明,33-1具有很好的苗期防治效果,可达86.95%,对植株生长有促进作用。认为33-1有开发为防治温室黄瓜枯萎病生防制剂的潜力。更多还原

【Abstract】 In order to effectively prevent and control cucumber Fusarium wilt in greenhouses and to obtain highly effective antagonistic strains with good biological control effect in Gansu province, several strains of Fusarium wilt were isolated from inter-rhizosphere soil in sunny greenhouses in Liangzhou district, Wuwei City, Gansu Province. We obtained a strain 33-1 Pseudomonas with strong inhibitory effect on Fuasrium oxypsorum through plate antagonism test and indoor potting effect test. 33-1 was identified as Pseudomonas frederiksbergensisi. The results showed that 33-1 had a good seedling control effect, up to 86.95%, and it can promote plant growth. It is considered that 33-1 has the potential to be developed as a bio-control agent against Fusarium wilt in greenhouse.更多还原
