Embodiment Construction

[0026] 1. Application in hydroponic breeding

[0027] Take the prepared bacteria liquid for the above endophytic fungi 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%.

[0028] 2. Application of rhizosphere soil irrigation

Abstract

The invention relates to an endophytic fungus promoting casuarina equisetifolia root system growth effect. The endophytic fungus is phyllosticta sp. casuarina equisetifolia rhizospheric fungus 15, which is registered and collected in China General Microbiological Culture Collection Center on June 28th, 2012. The collection number is CGMCC No. 6307. The fungus is inoculated in casuarina equisetifolia hydroponic seedling. Comprehensive evaluation is carried out according to various indicators of root system growth, and it is further proved that the casuarina equisetifolia rhizospheric fungus 15 has a promotion effect upon rooting and an actual synergetic effect upon casuarina equisetifolia dry matters. When a functional endophytic fungus beneficial for promoting rooting effect 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 the root system of Casuarina equisetifolia. Background technique [0002] The research on plant endophytes began at the end of the 19th century. Vogl isolated the first endophytes from the seeds of Lolium temulentum L. [1] . However, a large number of studies on endophytes in plants began in the 1980s, mainly in the vegetation of temperate, subtropical and tropical regions. [0003] Predecessors can isolate endophytes from most plants, so it can be inferred that endophytes are ubiquitous in plants. Endophytes have been found in at least 290 species of gramineous crops in more than 80 genera worldwide [2] . The endophytes currently isolated from plants can be divided into: nitrogen-fixing bacteria, potassium-fixing bacteria, phosphorus-fixing bacteria and other plant growth-promoting bacteria according to their unique functions [3~4] , Biocontrol bacteria resistant to pests and ...
