Problems solved by technology

There are still large areas of drought-flooded saline-alkali land in the Huang-Huai-Hai region that have not been improved. In the past, in order to increase production, irrigation was carried out without considering drainage conditions, resulting in severe secondary salinization

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...

Abstract

The invention provides a compound microbial agent which is prepared by mixing the following microorganisms in equal proportion: Bacillus megaterium GRINML5, Azotobacter salinestris strain GRINML6, Pseudomonas sp GRINML7, Bacillus licheniformis GRINML8, Stenotrophomonas sp. GRINML9 and Brevibacterium sp GRINM L2. The invention also provides a method for soil fertility enhancement and ecological improvement by using the compound microbial agent. A plurality of strains of microorganisms beneficial to plant growth are separated from an environment and are artificially compounded to form microbialfertilizer. A microbial ecological system for promoting solidification, release and conversion of vegetation nutrients is built by artificially supplementing the microbial fertilizer into soil to promote plant growth, the virtuous cycle that microorganisms promote plant growth, plants promote microorganism growth and plants and microorganisms promote each other is gradually formed, and the soil ecology is fundamentally improved.

Description

technical field [0001] The invention belongs to the fields of soil fertilization and ecological environment restoration, and relates to a compound microbial bacterial agent and a method for soil fertilization and ecological improvement. Background technique [0002] Soil impoverishment, also known as soil degradation, is a comprehensive characterization of soil environment and soil physical, chemical and biological characteristics deterioration, such as the decline of organic matter content, nutrient element deficiency, soil structure destruction, soil erosion, soil layer thinning, soil Compaction, soil acidification, alkalization, desertification, etc. Among these characterizations, a decline in organic matter content can serve as an important indicator of soil degradation, which is linked to many soil properties. For example, the organic matter content of the newly reclaimed black soil in Northeast my country is 7-10%, but within a hundred years of reclamation, the soil o...
