Embodiment Construction

[0022] 1. Application of rhizosphere soil watering and seedling direct inoculation

[0023] 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 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 gr...

Abstract

The invention relates to an endophytic fungus for promoting the growth and photosynthesis enhancement of aleurites montana in low-phosphorus environment. The endophytic fungus is Penicillium sp. SJ4 registered and preserved in China General Microbiological Culture Collection Center with the preservation number of CGMCC No. 10466 on 30th January, 2015. The endophytic fungus SJ4 for aleurites montana is inoculated to a soil-cultured aleurites montana seedling, a low-phosphorus stress experiment on the inoculated plant shows that the seedling height increase rate, ground diameter increase rate and SPAD value of the plant are far higher than those of a contrast, the endophytic fungus has a better effect on alleviating the low-phosphorus stress of the plant, and further, the endophytic fungus of the plant promotes the growth and development of aleurites montana in the low-phosphorus environment.

Description

technical field [0001] The invention relates to an endophytic fungus which promotes the growth of tung tree and enhances photosynthesis under 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 nitro...
