Embodiment 1
[0034] The alkaloid saline-alkali soil conditioner described in this embodiment is prepared from the following components in parts by weight through the following steps:
[0035] (1) Inoculate the preserved Rhodopseudomonas marsh, Pichia membranum, Lactobacillus casei, and Streptomyces flavinus into a sterile sterile solution containing carbon source, nitrogen source, inorganic salt and water, respectively. In the culture medium, and cultivated under the adaptation conditions for 3-5 days respectively, then the bacterial classification obtained by fermentation is mixed for subsequent use according to the weight ratio of 3:5:4:3;
[0036] (2) The kelp is sterilized and disinfected at high temperature (above 100°C), soaked for 48 hours, pulverized to 80 mesh, ground to 120 mesh, extracted from mannitol and sodium alginate, and then transported to a pulping machine for pulping to obtain the obtained Said seaweed slurry;
[0037] (3) Mix 5 parts of bacterial species obtained in s...
Embodiment 2
[0042] The alkaloid soil conditioner of the present invention is prepared by the following preparation method:
[0043] (1) Inoculate the preserved Rhodopseudomonas marsh, Pichia membranum, Lactobacillus casei, and Streptomyces flavonoids into a sterile sterile solution containing carbon source, nitrogen source, inorganic salt and water, respectively. In the culture medium, cultured for 3-5 days under adaptation conditions, respectively, the culture solutions obtained from each fermentation were mixed according to a weight ratio of 6:3:2:1 to obtain the required bacterial species for subsequent use;
[0044] The Lactobacillus casei culture medium formula is: peptone 10g, meat extract 10g, yeast extract 5g, dipotassium hydrogen phosphate 2g, triammonium citrate 2g, sodium acetate 5g, glucose 20g, Tween-80 1mL, MnS0 4 ·H 2 O 0.25g, MgS0 4 ·7H 2 O 0.58g, agar 20g, sterilized CaCO 3 10g, distilled water 1000mL. Adjust the pH value to 6.2-6.4, put the prepared culture medium i...
Embodiment 3
[0054] The alkaloid saline-alkali soil conditioner described in this embodiment is prepared from the following components in parts by weight through the following steps:
[0055] (1) Mix the preserved Rhodopseudomonas marsh, Pichia membranum, Lactobacillus casei, and Streptomyces flavis and inoculate them into a suitable sterile culture containing carbon source, nitrogen source, inorganic salt and water In the base, cultivate at 25-35°C for 3-5 days to obtain the required strains for use;
[0056] Described culture medium comprises: glucose 30g / L, bran 20g / L, yeast extract 5g / L, MgSO 4 2g / L, distilled water, adjust pH to 5.0.
[0057](2) The kelp is sterilized and disinfected at high temperature (above 100°C), soaked for 48 hours, pulverized to 80 mesh, ground to 120 mesh, extracted from mannitol and sodium alginate, and then transported to a pulping machine for pulping to obtain the obtained Said seaweed slurry;
[0058] (3) Take 5 parts of bacterial species obtained in s...
