Abstract

The present disclosure relates to the technical field of agricultural microorganisms and crop cultivation and more specifically relates to a compound mycorrhizal fungus growth promoting agent and an agricultural-photovoltaic complementary planting method for Dioscorea composita . The compound mycorrhizal fungus growth promoting agent for Dioscorea composita includes Glomus mosseae, Streptomyces chartreusis and plant growth promoting rhizobacteria, and can greatly improve photosynthesis of Dioscorea composita under a photovoltaic panel and promote growth and development of Dioscorea composita . The compound mycorrhizal fungus growth promoting agent is used, an unoccupied land under a solar photovoltaic panel is utilized, and a high-ridge close planting method is used to combine a solar photovoltaic industry and Dioscorea composita planting. The whole planting process is easy to operate, the cost is low, and three-dimensional value-added utilization of land is achieved.

First claim

What is claimed is:

1. A compound mycorrhizal fungus growth promoting agent for Dioscorea composita , wherein the compound mycorrhizal fungus growth promoting agent consists of Glomus mosseae, Streptomyces chartreusis and Flavisolibacter ginsengiterrae ; spore suspensions of the Glomus mosseae, Streptomyces chartreusis and Flavisolibacter ginsengiterrae have a concentration equal to or greater than 4,000 spores/mL; and based on volumes of the spore suspensions with the same concentration, a ratio of the Glomus mosseae, Streptomyces chartreusis and Flavisolibacter ginsengiterrae in the compound mycorrhizal fungus growth promoting agent is 3:3:1.

2. A microbial preparation for promoting growth and improving photosynthetic efficiency of Dioscorea composita , containing the compound mycorrhizal fungus growth promoting agent for Dioscorea composita according to claim 1 .

3. An agricultural-photovoltaic complementary planting method for Dioscorea composita , comprising:
infecting a Dioscorea composita seedling with the compound mycorrhizal fungus growth promoting agent according to claim 1 ; and
planting or growing the Dioscorea composita seedling beneath or between rows of photovoltaic panels.

4. The agricultural-photovoltaic complementary planting method for Dioscorea composita according to claim 3 , comprising:
infecting the Dioscorea composita seedling by soaking a root of a Dioscorea composita cutting seedling with the compound mycorrhizal fungus growth promoting agent; and
field-planting the seedling beneath or between rows of photovoltaic panels in nutrient soil containing the compound mycorrhizal fungus growth promoting agent.

5. The agricultural-photovoltaic complementary planting method for Dioscorea composita according to claim 4 , wherein the nutrient soil is obtained by cultivating Trifolium repens with the compound mycorrhizal fungus growth promoting agent for Dioscorea composita in the soil, and preparing the nutrient soil containing a spore, a mycelium and an infected root segment.
