Embodiment Construction
[0010] (1) Collect soil samples, remove large particles such as stones, crush and air-dry, and sieve.
[0011] (2) Place 20g of the sample in 200mL of sterile water, shake it fully, and use this solution as the mother solution for gradient dilution.
[0012] (3) Take 10 -6 0.1mL of the diluent was used to coat the No. 1 plate of Gao Shi.
[0013] (4) Culture at 28°C for 7 days.
[0014] (5) Separate and save single colonies of different colors and traits.
[0015] (6) Mix Myrica rubra (the strain was isolated from the diseased strains in Cixi Yangmeiyuan in our laboratory and identified as Myrica rubra by morphology and molecular biology) with the bacterial culture medium at 30°C, and make a plate after cooling. Make a hole on the plate, dig out the agar block, drop 20 μL of the bacterial suspension of the isolated strain into the hole, incubate at 28°C, and observe the size of the inhibition zone. (7) Purify the strains with the inhibition zone for single colony.
