Embodiment 1
[0033] Prepare photosynthetic bacteria culture medium according to the following components:
[0034] Sodium acetate 1000-2000mg CaCl2.2H2O 50-100 mg
[0035] MgSO4.7H2O 100-300 mg EDTA 10-30 mg
[0036] Yeast extract 500-1500 mg K2HPO4 500-1500 mg
[0037] (NH4)2SO4 1000-2000 mg KH2PO4 400-1000 mg
[0038] FeSO4. 7H2O 5-15mg trace element solution 1-5m1
[0039] Deionized water 1000-2000 ml pH 6 - 8
[0040] Wherein the trace element solution consists of:
[0041] H3BO3 200-300 mg Na2MoO4.2H2O 50-100 mg
[0042] CuSO4 2-10 mg MnSO4. 4H2O 150-250 mg
[0043] ZnSO4.7H2O 20-30 mg Deionized water 100-200 ml
[0044] Introduce 1 / 10 of the photosynthetic bacteria seed culture solution into the sterilized photosynthetic bacteria culture medium, anaerobic culture at a temperature of 15°C - 20°C; light intensity of 1800lux for 10 days, and the number of viable bacteria is 108— 1010 cfu / ml photosynthetic bacteria culture solution.
[0045] In the...
Embodiment 2
[0047] The preparation method of photosynthetic bacteria culture medium is the same as embodiment 1.
[0048] Introduce 1 / 5 of the photosynthetic bacteria seed culture solution into the sterilized photosynthetic bacteria culture medium, anaerobic culture for 8 days at a temperature of 15°C - 20°C; light intensity of 1200lux, and the number of viable bacteria is 108- 1010 cfu / ml photosynthetic bacteria culture solution.
[0049]In the middle and lower reaches of the Yangtze River, muskmelon seedlings are generally cultivated in protected areas in early and mid-January. Before sowing, in addition to ordinary high-temperature soaking, the seeds are soaked in photosynthetic bacteria culture solution diluted to 100 times the original volume for 60 minutes. After the seedlings are settled, the photosynthetic bacteria culture solution is diluted to 100 times of the original volume with water, and the roots are irrigated with the amount of 10 kg / mu. Dilute the photosynthetic bact...
