preparation example 1

[0029] The said Agrocystis moxie is planted and propagated in advance through corn, and the spores, extra-root hyphae and the root soil mixture of the infected corn root segment are used as the moxie fungus agent, and each gram of the moxie fungus is The cyst mold contains 25-35 spores. Specifically, the breeding steps include:

[0030] The spores, hyphae and soil samples of infected plant roots were used as the initial inoculant, and corn or sudangrass were used as host plants.

[0031] Use the mixture of farmland soil and organic fertilizer as the propagation substrate, air-dry the farmland soil and organic fertilizer separately and pass through a 2mm sieve. After sieving, mix the farmland soil and organic fertilizer evenly at a volume ratio of 2:1. The fertilizers are sterilized separately before mixing or sterilized after mixing to obtain the propagation substrate. Wherein, the sterilization method of the multiplication substrate is steam sterilization at 121° C., and af...

preparation example 2

[0035] Mix the Pachyderm moxie fungus agent and Trichoderma harzianum wettable powder according to the mass ratio of 1:5 to form a mixed fungal powder, which is the microbial inoculum agent II suitable for Dendrobium wilt.

preparation example 3

[0037] Mix the Pachyderm moxie fungus agent and Trichoderma harzianum wettable powder according to the mass ratio of 1:4 to form a mixed fungal powder, which is the microbial inoculum agent three suitable for Dendrobium wilt.

Abstract

The invention provides a microbial agent suitable for dendrobium wilt and application of the microbial agent, relates to the technical field of dendrobium planting. A mixture of a funneliformis mosseae microbial agent and a trichoderma harzianum microbial agent is used as the microbial agent,the growth of root systems of dendrobium tissue culture seedlings can be promoted, and the growth promotingeffect of the funneliformis mosseae microbial agent and the trichoderma harzianum microbial agent is superior to that of the independently inoculated funneliformis mosseae microbial agent and trichoderma harzianum microbial agent, so that it is proved that funneliformis mosseae and trichoderma harzianum have a synergistic effect in the aspect of controlling the dendrobium wilt.

Description

technical field [0001] The invention relates to the technical field of dendrobium planting, in particular to a microbial agent suitable for dendrobium wilt and its preparation method and application. Background technique [0002] Dendrobium spp. is a relatively large genus of epiphytes in the family Orchidaceae. At present, about 1,000 species have been found in the world. In my country, there are 74 species and 2 varieties. The common ones are Dendrobium candidum, Dendrobium spp. Dendrobium officinale, Dendrobium bougainvillea, Dendrobium Huoshanense, etc. Among them, Dendrobium candidum and Dendrobium nobile are included in the previous editions of Chinese Pharmacopoeia. They have the functions of promoting body fluid and nourishing yin, and are important resources of traditional Chinese medicines. Dendrobium is an epiphytic plant with fleshy roots. It is a typical mycorrhizal plant and has abundant endophytic fungi. Due to the long planting cycle of Dendrobium candidum, it...
