Embodiment 1 3
[0049] Example 1 Demonstration of Microbial Conservation Technology Demonstration of Baopo Ridge III Mountain and its Bottom in Sanya City
[0050] The mountain of Baopo Ridge III in Sanya City is an exposed stone mountain. The V-shaped groove construction and vegetation cultivation have been completed. The soil in the V-shaped groove of the mountain is rich in sand, less in clay, and poor in nutrients, making it difficult for plants to grow. The bottom of the mountain is mostly construction waste and sand, which lacks nutrients and makes it difficult for plants to grow.
[0051] The method for specific soil fertilization and ecological improvement in the above-mentioned areas includes the following steps:
[0052] 1. Compound the above-mentioned microorganisms in equal proportions to form a compound microbial fertilizer.
[0053] 2. Preparation of medium: The medium formula is: glucose 1.2g / L, K 2 HPO 4 0.6g / L, peptone 0.5g / L, (NH 4 ) 2 CO 3 0.5g / L, CaCl 2 0.1g / L, M...
Embodiment 2
[0063] Example 2 Demonstration of microbial conservation in turf greening area
[0064] This area is the greening turf of the newly-built community. Because there is a lot of construction waste and sand in the site, the vegetation grows unevenly, and some areas are dry.
[0065] The method for specific soil fertilization and ecological improvement in the above-mentioned areas includes the following steps:
[0066] 1. Compound the above-mentioned microorganisms in equal proportions to form a compound microbial fertilizer.
[0067] 2. Preparation of medium: The medium formula is: glucose 0.8g / L, K 2 HPO 4 0.5g / L, peptone 0.5g / L, (NH 4 ) 2 CO 3 0.5g / L, CaCl 2 0.1g / L, sodium lactate 0.2g / L, add the above dosage into 1L of distilled water, sterilize at 121°C for 20min, and cool to room temperature;
[0068] 3. Add the compounded compound bacterial agent to the medium, the amount added accounts for 5% of the volume of the medium, and culture it on a shaker at 200 rpm at 30...
