Embodiment Construction

[0021] 1. Application of rhizosphere soil watering and seedling direct inoculation

[0022] The test material is the millennium paulownia seedlings provided by Jianyang Forestry Bureau as an annual seedling. This experiment adopts the 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 2014. Put 3kg of yellow heart soil of equal quality into 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 pot mouth 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 root growth of aleurites montana in a low-phosphorous environment. The endophytic fungus is penicillium sp. ZG3 and has been registered and preserved in the China General Microbiological Culture Collection Center (CGMCC) on January 30th, 2015. The preservation number is CGMCC No. 10467. According to the invention, the endophytic fungus ZG3 of aleurites montana is inoculated to land culture seedling of aleurites montana. By measurement of plant dry weight and SOD activity, root cap ratio and SOD activity of a plant inoculated with the strain are higher than those of a contrast to a greater degree. It shows that the strain has a great function of promoting root growth of a plant and resisting a low-phosphorous environment. Thus, it is further confirmed that the endophytic fungus can promote root growth of aleurites montana in a low-phosphorous environment.

Description

technical field [0001] The invention relates to an endophytic fungus which can promote the growth of the root system 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 ...
