Embodiment Construction

[0023] 1. Application of rhizosphere soil watering and seedling direct inoculation

[0024] The test material is the millennium paulownia seedlings provided by Jianyang Forestry Bureau as an annual seedling. This experiment adopts soil cultivation pot experiment, selects seedlings with consistent growth and planted them in plastic pots with a diameter of 15 cm and a height of 10 cm in May 2015. Put 3kg of yellow heart soil of equal quality in each pot. In order to ensure the accuracy of inoculation of seedlings in the later stage, add 10-15 drops of formaldehyde (formalin) disinfectant to each pot of soil, and cover the mouth of the pot with a plastic film for disinfection. The time is 24h. After the formaldehyde infiltration and disinfection in the soil is complete, the plastic film is removed, and the remaining formaldehyde is evaporated, so as not to affect the survival rate of seedling transplantation. The seedlings were implanted, and after a month of restorative growth...

Abstract

The invention relates to an endophytic fungus for promoting biomass growth of aleurites montana in a low-phosphorus environment. The endophytic fungus is Penicillium sp. SJ3, has been registered and collected in the General Microbial Center of China Committee for Culture Collection of Microorganisms on January 30, 2015, and has a collection number of CGMCC No.10468. An aleurites montana endophytic fungus SJ3 is inoculated into an aleurites montana soil culture seedling; and by measuring the biomass of plants, the acid phosphatase activity of leaves and the acid phosphatase activity of roots, results show that the biomass, the leaf acid phosphatase activity and the root acid phosphatase activity of the plants inoculated with a strain are basically higher than that of comparisons to a relatively high extent, and show that the aleurites montana endophytic fungus SJ3 has a great effect on promoting the biomass growth of the plants in the low-phosphorus environment so as to further verify that the endophytic fungus can be used for promoting the biomass growth of aleurites montana plants in the low-phosphorus environment.

Description

technical field [0001] The invention relates to an endophytic fungus which promotes the biomass growth of the millennium tung tree in a low-phosphorus environment. Background technique [0002] The research on plant endophytes began at the end of the 19th century when Vogl isolated the first endophytes from the seeds of Lolium temulentum L. ryegrass. However, a large number of studies on endophytes in plants began in the 1980s, mainly in vegetation in temperate, subtropical and tropical regions. [0003] Plant endophytic fungi have a wide distribution and many types. Previous studies have shown that endophytic fungi can be isolated from most plants. It can be seen that endophytic fungi generally exist in plants. Endophytes have been found in at least 80 genera and 290 species of grass crops worldwide. At present, the endophytes isolated from plants can be divided into three types according to their unique functions: plant growth-promoting bacteria such as nitrogen-fi...
