Embodiment Construction

[0020] 1. Application of rhizosphere soil watering and seedling direct inoculation

[0021] 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 endophytic fungi for promoting photosynthesis of aleurites montana under a low-phosphor environment. The endophytic fungi is Thermomyces sp. SY1 registered and preserved in General Microbiological Center of China Committee for Culture Collection of Microorganisms on January 30, 2015 with the preservation number of CGMCC No. 10469. According to the measurement on chlorophyll fluorescence parameters of a plant, the Fv/Fm and Fv/F0 of the treatment of inoculating the bacterial strain are much higher than those of a control group, and the endophytic fungi is shown to have great effects in promoting photosynthesis of the plant, so that the endophytic fungi in the strain is further proved to have strengthened effects in promoting photosynthesis of aleurites montana under the low-phosphor environment.

Description

technical field [0001] The invention relates to an endophytic fungus which promotes the photosynthesis of the millennium paulownia 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...
