Embodiment Construction

[0024] 1. Application in hydroponics

[0025] Take the prepared casuarina rhizosphere fungus 7 application bacteria 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%.

[0026] 2. Application of rhizosphere soil watering

Abstract

The invention relates to an endophytic fungus promoting casuarina equisetifolia photosynthesis. The endophytic fungus is aspergillussp. casuarina equisetifolia rhizospheric fungus 7, which is registered and collected in China General Microbiological Culture Collection Center on June 28th, 2012. The collection number is CGMCC No. 6305. The casuarina equisetifolia rhizospheric fungus 7 is inoculated in casuarina equisetifolia hydroponic seedling. Comprehensive evaluation is carried out according to various indicators of photosynthesis, and it is further proved that the fungus has a promotion effect upon photosynthesis. When a functional endophytic fungus beneficial for promoting photosynthesis is found, the endophytic fungus can be used in production. Through a fungus solution watering method, the endophytic fungus is inoculated on casuarina equisetifolia seedlings. The endophytic fungus has substantial effects in promoting plant photosynthesis and increasing casuarina equisetifolia dry matter accumulation.

Description

technical field [0001] The invention relates to an endophyte fungus which promotes photosynthesis of casuarina. 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 [5~8] And resistant b...
