Embodiment Construction

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

[0022] This experiment adopts soil culture pot experiment, and the material used in the experiment is Taiwan Acacia annual seedling provided by Forestry Bureau of Zhangzhou City, Fujian Province. Select Taiwan acacia seedlings with consistent growth to plant in diameter 15cm, high 10cm plastic pots. The soil used is yellow heart soil that has been strictly fumigated. After mixing and weighing, put an equal amount of 3kg of soil into each pot. After one month of restorative growth, the rhizosphere of Acacia Taiwan was applied at a concentration of 5.5×10 6 100mL bacterial solution of cfu / ml, use distilled water as blank control.

[0023] Bacterial liquid preparation: Inject the test strain into 40mL liquid medium, the medium is modified Martin's medium, in which peptone 5.0g / L, yeast extract powder 2.0g / L, glucose 20.0g / L, dipotassium hydrogen phosphate 1.0 g / L, magnesium sulfate 0.5g / L, an...

Abstract

The invention relates to an endophytic fungus which can promote the absorption of nutrient elements of Taiwan Acacia in a low-phosphorus environment. The endophytic fungus is Filobasidium F, which was registered and preserved in the General Microorganism Center of China Microbiological Culture Collection Management Committee on January 27, 2016, and the preservation number is CGMCC No.12102. The endophytic fungus F of Acacia taiwanensis was inoculated in the soil culture seedlings of Acacia taiwanensis, and through the determination of the carbon content and nitrogen content of the plants, it was concluded that the carbon content and nitrogen content of the treated plants inoculated with the strain were basically greater in a low phosphorus environment. It is higher than the control, indicating that it has a great effect on promoting the absorption of nutrient elements in plants in a low-phosphorus environment, thereby further confirming that the endophytic fungi of this strain can promote the absorption of nutrient elements in Taiwan Acacia plants in a low-phosphorus environment.

Description

technical field [0001] The invention relates to an endophytic fungus which can promote the absorption of nutrient elements of Taiwan acacia 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...
