Embodiment Construction

[0022] 1. Application in hydroponics

[0023] Take the prepared casuarina rhizosphere fungus 17 (strain 17) and apply the bacterial liquid to make 5.0×10 5 cfu / ml bacterial solution, soak the roots for 10 minutes before planting the hydroponic seedlings. It can increase the survival rate of seedlings by more than 10%.

[0024] 2. Application of rhizosphere soil watering

Abstract

The invention relates to an endophytic fungus promoting casuarina equisetifolia biomass growth. The endophytic fungus is aspergillus sp. casuarina equisetifolia rhizospheric fungus 17, which is registered and collected in China General Microbiological Culture Collection Center on June 28th, 2012. The collection number is CGMCC No. 6309. The casuarina equisetifolia rhizospheric fungus 17 is inoculated in casuarina equisetifolia hydroponic seedling. Comprehensive evaluation is carried out according to various indicators, and it is further proved that the fungus has a promotion effect upon biomass growth and an actual synergetic effect upon casuarina equisetifolia dry matters. When a functional endophytic fungus beneficial for promoting biomass growth is found, the endophytic fungus can be used in production.

Description

technical field [0001] The invention relates to an endophytic fungus capable of promoting the growth of casuarina biomass. Background technique [0002] The study of plant endophytes began at the end of the 19th century when Vogl isolated the first endophytes from the seeds of ryegrass Lolium temulentum L. [1] . However, a large number of studies on endophytes in plants began in the 1980s, mainly in vegetation in temperate, subtropical and tropical regions. [0003] The predecessors can isolate endophytes from most plants, so it can be speculated that endophytes are ubiquitous in plants. Endophytes have been found in at least 80 genera and 290 species of grass crops worldwide [2] . According to their unique functions, the endophytes isolated from plants can be divided into: nitrogen-fixing bacteria, potassium-fixing bacteria, phosphorus-fixing bacteria and other plant growth-promoting bacteria [3~4] , Biocontrol bacteria with resistance to pests and diseases [5~7] And ...
