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 solution preparation: Inject the tested 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...

Abstract

The invention relates to an endophytic fungus promoting acacia confusa biomass growth under a low-phosphorous environment. The endophytic fungus is Penicillium sp. and is registered and preserved in Center of general microbiology of China Committee for Culture Collection of Microorganisms on January 27, 2016, and the preservation number is CGMCC No.11913. Acacia confusa normal plantlets are inoculated with an acacia confusa endophytic fungus I, by measuring the heights and the biomass of plants, it is concluded that the heights and the biomass of the treated plants inoculated with the endophytic fungus I under the low-phosphorous environment are much higher than those of contrasts, it shows that the endophytic fungus I has a very large effect on promoting the plant biomass growth under the low-phosphorous environment, and therefore it is further proved that the endophytic fungus can promote the acacia confusa biomass growth under the low-phosphorous environment.

Description

technical field [0001] The invention relates to an endophytic fungus which promotes the biomass growth of Acacia taiwanensis 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-fixing bacteri...
