preparation example 1

[0029] Described Moxiella fungus is planted and propagated through corn in advance, and the spores, extra-root mycelium and the root soil mixture of the infected corn root section are used as Mosaic fungus agent, and each gram Mosaic fungus 25-35 spores are contained in the saccharomycete agent. Specifically, the breeding steps include:

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

[0031] Using the mixture of farmland soil and organic fertilizer as the propagation matrix, the farmland soil and organic fertilizer were air-dried and passed through a 2mm sieve. After sieving, the farmland soil and organic fertilizer were mixed evenly in a volume ratio of 2:1. Fertilizers are sterilized before mixing or sterilized after mixing to obtain a propagation matrix. Among them, the sterilization method of the multiplication matrix is ​​steam sterilization at 121° C., taking out an...

Abstract

The invention provides a microbial inoculant suitable for dendrobium fusarium wilt and its application, and relates to the technical field of dendrobium planting. The mixture of the inoculum of moses douche and the inoculum of Trichoderma harzianum is used as the microbial inoculant, which can not only promote the The growth of the root system of Dendrobium tissue culture seedlings, and the growth-promoting effect of the inoculum of moses and Trichoderma harzianum is better than the inoculation of moxii or Trichoderma harzianum alone. There is a synergistic effect between Dendrobium wilt and Trichoderma harzianum.

Description

technical field [0001] The invention relates to the technical field of dendrobium planting, in particular to a microbial inoculum suitable for dendrobium fusarium wilt and a preparation method and application thereof. Background technique [0002] Dendrobium (Dendrobium spp.) is the largest genus of epiphytes in the orchid family. At present, about 1,000 species have been found in the world. There are 74 species and 2 varieties in my country. Dendrobium officinale, Dendrobium officinale, Dendrobium huoshanense, etc., of which Dendrobium officinale and Dendrobium chinensis have been included in the previous editions of Chinese pharmacopoeia, and have the functions of promoting body fluid and nourishing yin, and are important Chinese herbal medicine resources. Dendrobium is an epiphytic plant with succulent roots. It is mostly grown on bark, trunk or stone crevices in the wild. It is a typical mycorrhizal plant with abundant endophytic fungi. Due to the long planting cycle of D...
