Problems solved by technology

However, arbuscular mycorrhizal fungi are highly symbiotic with plants and have the characteristics of obligate nutrition, so it is difficult to obtain pure culture, while ectomycorrhizal fungi grow slowly, which restrict the production and application of mycorrhizal fungi It is Difficult to Promote the Use of Mycorrhizal Fungi in Slope Restoration Projects

Embodiment Construction

[0025] 1. Inoculation test of arbuscular mycorrhizal fungi

[0026] The stolon cuttings of Indigo indigo and Peanut vine were mixed with the fungus agents of Glomus mosseae, Glomus intraradices and Glomus etunicatum respectively, and watered regularly. Water conservation until the potted plants are overgrown. The root infection rate of Indigo indigo is about 95.33±1.58%, and the root infection rate in Peanut vine is 91.67±0.53%. It is detected by wet sieving and decantation staining method, and the arbuscular branches proliferated by cutting Indigo indigo and Peanut vine The spore density of the fungal agent is about 60-90 spores / 10g. Experiments have proved that the application of mycorrhizal fungi to slopes has the following benefits.

[0027] 2. Arbor inoculation test with ectomycorrhizae

[0028] 1. Can promote plant growth

[0029] Select Taiwan Acacia seedlings with the same growth and specifications close to the plant height of 25±1.27cm and the ground diameter of 2...

Abstract

The invention discloses a method for promoting side slope green retrieval through mycorrhiza inoculation. Firstly, stolons of plants undergo cuttage in a matrix mixed with arbuscular mycorrhizal fungi, and watering and maintenance are performed for propagation expanding; the plants obtained through the propagation expanding are taken out, the stolons are sheared into stem sections with adventitious roots and the matrix; fermentation broth of ectotrophic mycorrhiza, side slope plant seeds and an organic fertilizer for sterilization are taken and mixed to obtain a mixture; a base material is spray-seeded on a side slope; the obtained plant stem sections and the mixture are mixed and spray-seeded; arbor seedlings are transplanted, the ectotrophic mycorrhiza and / or the arbuscular mycorrhizal fungi are taken to wrap broken roots of the arbor seedlings or the ectotrophic mycorrhiza and / or the arbuscular mycorrhizal fungi is scattered to pits, the arbor seedlings are planted in the pits; the stem sections spray-seeded with a bacterium carrying agent can be used for inoculating the arbuscular mycorrhizal fungi to all the side slope plants, the side slope plants and the spray-seeded stolon section plants grow rapidly, the demand for rapid green retrieval at the earlier stage of side slope green retrieval can be met, mycorrhiza fungi inoculation is specifically conducted on the arbor seedlings, and the demand for keeping vegetation for a long period of the side slope can be met.

Description

technical field [0001] The invention relates to the technical field of slope regreening, in particular to a method for promoting slope regreening through mycorrhizal inoculation. Background technique [0002] Due to the characteristics of steep slope, high slope, and poor soil environment, manual excavation of slopes usually does not have the soil, water, and nutrient conditions for vegetation to survive, making it difficult to restore vegetation on slopes. In addition, due to the long slopes and large areas of roads, hydropower and other infrastructure projects, manual maintenance is relatively difficult, and coupled with limited investment funds, slope plants are generally in a self-supporting state. At the same time, the commonly used spraying plants on slopes have certain selectivity and adaptability to climate and environment, and their own stress resistance is limited, and they are easy to degrade and die under low or no maintenance conditions. Failure to solve the pr...
