In this paper, 1554 strains of bacteria were isolated from the soybean rhizophere in the different continuous systems. Those biocontrol bacteria were screened in vitro and in vivo. 6 strains of them had the better control efficacy. They exhibited the different antagonism to the pathogens of soybean root in vitro. The strains 18BR2-2 and 18BR9-1 showed a wide range of antagonism against Fusarium oxysporum, F. avenaoeum, F. solani and Rhizoctonia solani in vitro. The 6 strains exhibited different control efficacy to soybean root rot in greenhouse and in field. In greenhouse, they could decrease the degree of soybean disease significantly, and the control efficacy of 18BR2-2 was the best and can reach 45.90%. In theory, soybean treated by 18BR2-2 may postpone the days of outbreaking of disease for 6 days. The strain 18BR2-2 also promoted the growth of soybean seedling and, raising the soybean height for 11.24%, increasing dry weight for 40.91% and fresh weight for 35.27%.

本研究从长期连作田种植的大豆及其根际土壤中分离细菌1554株，采用平板测试、温室盆栽及田间试验等方法，筛选了对大豆根腐病菌(主要是尖孢镰孢菌Fusarium oxysporum)有很好作用效果的生防细菌6株，在离体的条件下均表现出不同程度的拮抗作用，其中生防细菌18BR2-2和18BR9-1表现出很广的杀菌谱，对大豆根腐病菌尖孢镰孢菌(F.oxysporum)、燕麦镰孢菌(F.avenaoeum)、茄腐镰孢菌和立枯丝核菌都有很好的离体拮抗作用，并且这6株生防细菌在盆栽和田间的情况下均表现出对大豆根腐病一定的防治效果。

We also studied their inhibition on H2O2,UV-induced hemolysis of RBC. Sodium paeonol sulfonate was used as keep-freshing agent in tomato storage and vitamin C content, brix, acidity, weight loss, membrane permeability, soluble protein content, SOD andPOD activity was determined. The results were as follows: Paeonol and sodiumpaeonol sulfonate had remarkably inhibitory effects on Xanthmonas oryzaepv.oryzicda,Pseudomonas solanacearum Smith, Phyllosticta mali Pril.et Delac.and Rhizoctonia solani Kuhn.
