从作物根际土壤中筛选出的一株小小的枯草芽孢杆菌成为蔬菜菌核病的克星。黑龙江省科学院应用微生物研究所用生物防治方法治疗蔬菜菌核病取得成功,日前,这项具有国内领先水平的生物防治方法通过了省级鉴定并被列入省重点推广项目。蔬菜菌核病是在高温多雨高湿环境下极易发生的一种蔬菜真菌病害,往往造成蔬菜茎叶枯死,减产可达30%,严重时多达50%。在棚室蔬菜如黄瓜、豆角、油菜、
A small strain of Bacillus subtilis screened from crop rhizosphere soil became the nemesis for sclerotinia in vegetables. Heilongjiang Academy of Sciences Institute of Applied Microbiology biological control methods of treatment of sclerotinia sclerotinia success, a few days ago, this has the leading domestic level of biological control methods passed the provincial appraisal and was included in the provincial key promotion projects. Vegetable sclerotinia is a vegetable fungal disease that easily occurs under the conditions of high temperature and rainy high humidity. It often causes the stems and leaves of vegetables to die, with a yield reduction of up to 30% and up to 50% in severe cases. In the greenhouse vegetables such as cucumbers, beans, rapeseed,
