Embodiment 1
[0023] The mycorrhizal fungus Umbelopsis dimorpha JSNL001-2 was prepared into a solid inoculum. The specific preparation method is as follows: using cottonseed shell fungus residue as a culture substrate, ammonium nitrate as an exogenous nitrogen source, and sucrose as an exogenous carbon source, prepare a solid culture substrate and put it in an autoclave bag at 121°C and 101.3 kPa Sterilize under high pressure for 20 minutes. After the culture medium is cooled, the mycorrhizal fungus JSNL001-2 is inoculated under aseptic conditions, and then cultured manually. The specific culture conditions were 28°C, 12h light + 12h darkness, pH 6.0, and culture for 30 days. Process the cultured bacteria into 1cm 3 Large and small masses are placed on the surface of the cultivation substrate for Dendrobium officinale seedlings planted that year. For the cultivation of Dendrobium officinale, a 15cm-diameter nutrient pot is used, and each nutrient pot is used to cultivate 1 cluster (5 plant...
