Abstract

The invention relates to the technical field of agricultural microorganism and crop cultivation, in particular to a compound mycorrhizal fungus growth promoting agent for dioscorea composita and an agricultural light complementary planting method for dioscorea composita. The compound mycorrhizal fungus growth-promoting agent for the dioscorea composita comprises glomus mosseae, streptomyces azofixing and plant rhizosphere growth-promoting bacteria, and can greatly improve the photosynthesis of the dioscorea composita under a photovoltaic panel and promote the growth and development of the dioscorea composita. By adopting the compound mycorrhizal fungus growth promoting agent, the unoccupied land under a solar photovoltaic panel is utilized, and solar photovoltaic and dioscorea composita planting are combined in a high-ridge close planting mode; the whole planting process is easy to operate and low in cost, and three-dimensional value-added utilization of the land is achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural microorganisms and crop cultivation. More specifically, it relates to a compound mycorrhizal fungi growth promoter of Dioscorea chrysanthemum and a method for complementary planting of Dioscorea chrysanthemum with agriculture and light. Background technique [0002] Dioscorea composita (scientific name: Dioscorea composita) is a perennial entwining herb of Dioscorea composita, with some underground stems shaped like palms, some of which are rod-like stacked; the outer skin is rough, dark brown, divided into dorsal and ventral sides; the root system is completely distributed On the abdomen; there are bud eyes on the tubers, which are difficult to identify with the naked eye. Dioscorea chrysanthemum rhizomes have high content of saponin and starch, and can be used for extracting diosgenin and fermenting to produce fuel ethanol, and the production cost is low, so the demand for chrysanthemum le...
