通过 Vali法和抑菌圈法测定了化学药剂和生防拮抗菌对冰核活性细菌的杀灭、抑制效果和对冰核活性的破坏作用 ,并用生测方法测定了药剂对活体植株上的冰核活性细菌的杀灭作用 ,又应用人工模拟霜冻法试验检测了药剂和生防菌的实际防御霜冻的效果。结果表明药剂和生防菌对冰核细菌都有一定作用。其中药剂作用快 ,对冰蛋白有破坏作用 ,生防菌作用持久 ,但对冰蛋白无明显破坏作用
The killing effect, inhibitory effect and disruptive activity of ice nucleation active bacteria on ice nucleation active bacteria were determined by Vali method and antibiosis circle method. The effects of chemical agent and biocontrol agent on ice nucleation activity Killing activity of nuclear-activated bacteria, and artificial simulated frost test was applied to detect the effect of anti-microbial agents and the actual defensive frost. The results show that the agents and biocontrol bacteria have some effect on the ice nucleate bacteria. Among them, the effect of the agent is quick, which has a damaging effect on the ice protein, long-lasting effect of biocontrol bacteria, but no obvious damaging effect on the ice protein
