Mycorrhizal fungi strain efficiently growing with rhododendron seedling

Abstract

The invention belongs to the field of microbiology and provides a mycorrhizal fungi strain efficiently growing with a rhododendron seedling. The problems of the prior art that the seedling growth is slow, the death rate is high, the leaves are yellow, and the like, during the artificial seedling culturing process for the rhododendron are solved. The preservation number of the mycorrhizal fungi strain provided by the invention is CGMCCNo:6010; the mycorrhizal fungi strain belongs to ascomycetes, chactomium globosum, discellaceae, oidiodendron; the mycorrhizal fungi strain provided by the invention can efficiently grow together with the rhododendron seedling; the rhododendron seedling is inoculated in a seedling stage; the infection rate of mycorrhiza is high; the growth of the seedling is obviously boosted; the survival rate of the seedling is increased; and when the pH of soil is 5.5-7.2, the strain inoculated on the seedling can effectively promote the growth of the seedling.

Description

Technical field: [0001] The invention relates to the field of microbiology, in particular to a fungal strain, in particular to a rhododendron-like mycorrhizal fungal strain, in particular to a mycorrhizal fungal strain that efficiently symbioses with rhododendron seedlings. Background technique: [0002] Rhododendron is one of the top ten traditional famous flowers in my country. It has the reputation of "the beauty of flowers" and has high ornamental value. It has always been loved by people. At the same time, my country is the main distribution center of Rhododendron in the world, with about 70% of Rhododendron species resources distributed in the world, and many precious Rhododendron resources are unique to my country. Rhododendron is an important component of vegetation in many nature reserves, forest tourist attractions or forest parks, forming a characteristic and prominent vegetation landscape, which has important ecological value and tourism development value.

AI Technical Summary

Problems solved by technology

In addition, Rhododendron is an acidic soil plant, and the optimum soil pH value is 4.5~5.5. In the artificial breeding environment, it is difficult to maintain the acidic environment of pH 4.5~5.5 in the cultivation soil. Often the soil pH is too high, which affects Rhododendron seedlings. nutrient absorption

Due to the above two reasons, rhododendron seedlings often grow slowly, with yellow leaves and high mortality, which has become a bottleneck for wild rhododendron hybrid breeding and seedling breeding.
