Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an inducer composition specially aimed at enhancing the infection ability of orchid endophytic fungi and forming effective mycorrhizal symbionts, which effectively solves the problem of orchid endophytic fungi or artificial inoculation agents. Orchid roots have low invasiveness and cannot form effective mycorrhizal symbionts. The present invention also provides a preparation method for this inducer composition

[0029] Weigh each component by weight as follows:

[0030] 4', 5, 7-trihydroxyflavone: 0.8g;

[0031] CaCl 2 : 15.0g;

[0032] Polyethylene glycol stearate: 15.0g;

[0033] Isopropanol and Macrogol 400: 40g.

[0034] The preparation process of this inducer composition is:

[0035] 1. Stir the above-mentioned weight of 4', 5, 7-trihydroxyflavone, polyethylene glycol stearate, isopropanol, and polyethylene glycol 400 at normal temperature and pressure;

[0036] 2. Heat the mixture in step 1 to 35°C and add CaCl 2 , Stir evenly, and it will be the finished product after standing still.

Embodiment 3

Abstract

The invention relates to a revulsant composition for promoting the formation of mycorrhizas homobium of orchid and a preparation method thereof. The revulsant composition mainly comprises active ingredients, surface active agent and latent solvent, wherein the active ingredients are flavonoid substance and calcium salt. The invention has the advantages that the revulsant composition better exerts the function of an inoculated strain by enhancing the infestation of endogenetic epiphyte at the root of orchid or the inoculated strain, fully ensures that the orchid root and the endogenetic epiphyte establish a symbiotic relationship to form effective mycorhiza, enhances the livability of the orchid and promotes the growth of the orchid; the revulsant composition has simple use method and little dosage; and the endogenetic epiphyte at the root of the orchid or the inoculated strain can establish the symbiotic relationship with the epiphyte at the root so as to promote the formation of the mycorrhizas homobium of the orchid in such a way that only a very small quantity of the revulsant composition is needed to be added to the orchid root when irrigating the orchid from the root, thereby having important economic value and being suitable for application and popularization.

Description

technical field [0001] The invention relates to an inducer composition for promoting the formation of orchid mycorrhizal symbiosis and a preparation method thereof. Background technique [0002] Orchidaceous mycorrhizae (orchidaceous mycorrhizae) are symbionts formed between the roots of orchidaceous plants and fungi, and they play an important role in the growth and life activities of orchidaceous plants. French biologist Bernard (Bereard) said in "Orchid Rhizome" written in 1959: "Orchids are symbiotic with rhizomes, and maintaining a balance between orchids and rhizomes is a necessary condition for orchids to grow well." Orchids and mycorrhizal fungi share two notable characteristics. One of the seeds is very small. Usually, a capsule contains hundreds of thousands of seeds. Their seeds do not contain endosperm, which are incompletely differentiated embryo cells. Photosynthesis in young leaves The substances required for germination cannot be provided before the action. ...
