Embodiment 1
[0049] Obtaining of strains:
[0050] 1. Collection of soil samples
[0051] (1) In summer, after rain. Collect soil samples within a range of about 5 cm to 10 cm below the surface of the crop rhizosphere soil;
[0052] (2) Select the diseased area, but the rhizosphere soil under the individual plants that have not diseased;
[0053] (3) Store in a sterile, air-permeable plastic bag.
[0054] 2. Enrichment culture
[0055] (1) Medium preparation
[0056] Ordinary nutrition agar plate g / L: beef extract 3.0, peptone 10.0, sodium chloride 5.0, purified water 1000ml, agar powder 2.0, pH=7.0~7.2, nystatin 50mg / L
[0057] (2) Soil sample treatment
[0058] Weigh 1g of soil sample, add it to 99ml of sterile water, shake for 15min with a shaker. Filter under sterile conditions to obtain filtrate
[0059] (3) Dilute the above-mentioned filtrate with sterile water according to the ten-fold gradient dilution method to 10 -3 , 10 -4 , 10 -5 , 10 -6
[0060] (4) Incubate the above diluent in a water bat...
Embodiment 2
[0092] Preparation of compound bacteria:
[0093] 1. The cultivation process of three strains of Bacillus amyloliquefaciens includes the following steps
[0094] 1) Preparation of solid slant strain
[0095] The three preserved strains were respectively inoculated on a slant medium, and kept standing at 37°C for 24 hours. The microscopic examination was free of bacteria and the spore rate was greater than 95%, and stored in a refrigerator at 4°C. Use within one year.
[0096] Used slope formula (weight ratio): glucose 0.1%, yeast extract powder 0.5%, peptone 0.1%, beef extract 0.5%, sodium chloride 0.02%, calcium chloride 0.01%, disodium hydrogen phosphate 0.04%, soluble starch 1.4%, ammonium sulfate 0.01%, manganese sulfate 0.1 mg / L, sodium molybdate 0.1 mg / L, agar powder 1.5%, and the balance is water. pH=7.1. 121℃, sterilize for 30min.
[0097] 2) Preparation of bottled liquid strain
[0098] Inoculate the fresh slant cultures of the three excellent strains obtained above into the ...
Embodiment 3
[0118] The difference from Example 2 is
[0119] 1. Preparation of solid slope strain
[0120] The preserved strains were inoculated on a slant medium, and incubated at 37°C for 24 hours. The microscopic examination showed no bacteria and the spore rate was greater than 95%, and stored in a refrigerator at 4°C. Use within one year.
[0121] The used slope formula (weight ratio): glucose 0.1%, yeast extract 0.5%, peptone 0.3%, beef extract 0.3%, sodium chloride 0.2%, calcium chloride 0.01%, disodium hydrogen phosphate 0.02%, soluble starch 2.0%, ammonium sulfate 0.01%, manganese sulfate 0.4mg / L, sodium molybdate 0.2mg / L, agar powder 2.0%, the balance is water. pH=7.1. 121℃, sterilize for 30min.
[0122] 2. Preparation of bottled liquid strain
[0123] The preserved fine slant strains are inoculated into liquid flask culture medium and cultured at 180rpm, 30℃~32℃, constant temperature shaking for 23h to obtain the flask liquid strains.
[0124] Liquid bottle formula used (weight ratio):...
