Application of waste compost composite bacterial agent to enhancing photosynthetic capacity of lawn grass

Abstract

The invention discloses application of a prepared domestic waste compost composite bacterial agent to enhancing photosynthetic capacity of lawn plants and promoting synthesis of chlorophyll. The composite bacterial agent consists of three strains, namely bacillus subtilis, actinomycetes and saccharomycetes in volume ratio of 1 to 1 to 1. Experiments show that seed germination rate, seedling height, aboveground dry weight, root weight, chlorophyll a content and chlorophyll b content of festuca arundinacea are 13.41 percent, 58.92 percent, 72.86 percent, 100 percent, 68.92 percent and 37.61 percent higher than contrast values respectively and the seed germination rate, the seedling height, the aboveground dry weight, the root weight, the chlorophyll a content and the chlorophyll b content of ryegrass are 15.11 percent, 34.44 percent, 71.74 percent, 100 percent, 66.89 percent and 33.41 percent higher than contrast values respectively after being treated by inoculating the three-strain composite bacterial agent. Technical effects show that the high-efficiency compost composite bacterial agent provides proper growth conditions and nutrients for plants, meets requirements on growth conditions required by the plants and therefore contributes to growth of the ryegrass and the festuca arundinacea.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to the preparation of a high-efficiency composting compound bacterial agent by using beneficial bacteria extracted from urban domestic garbage composting as raw materials. More specifically, it is the application of the preparation of compound bacterial agent in enhancing the photosynthetic ability of lawn plants and promoting the synthesis of chlorophyll. Background technique [0002] Composting is a biochemical process that uses microorganisms (bacteria, actinomycetes, fungi, etc.) widely present in nature or commercial strains to controlly promote the transformation of biodegradable organic matter into stable humus (humic substance, HS). . This process is also part of the ecological process on the earth's surface, which participates in the cycle of matter and energy on the earth's surface. [0003] Under artificial control conditions, the organic matter in solid ...

Problems solved by technology

However, in the research process of compound microbial agents, the identification and classification of microbial species in compost, the symbiosis and mutual influence relationship between compost strains are ambiguous and complex, and the application of compost microbial agents to plants under normal conditions In terms of the effect on growth, there are few related studies reported

However, the identification and classification of microbial species in compost, the symbiosis and mutual influence relationship between compost strains are fuzzy and complex, and the extraction, screening and preparation of compost compound beneficial microbial agents from municipal solid waste compost have a great impact on the growth of lawn plants. , Physiological properties of the impact of research has not been reported
