Embodiment Construction

[0022] 1. Application of rhizosphere soil watering

[0023] The test material was Huian No. 1 hydroponic seedlings, which were potted in the field experiment site of Forest Ecology Research Institute of Fujian Agriculture and Forestry University in July 2011.

[0024] After the root system of the hydroponic seedlings has grown, move them into the soil mixed with yellow heart loam and sand at a ratio of 3:1, and distribute them in about 500 flower pots with a diameter of 22 cm and a height of 15 cm. Put 3.36KG mixed soil of equal quality into each pot. In order to ensure the accuracy of seedling inoculation in the later stage, add 10-15 drops of formaldehyde (formalin) disinfectant to each pot of soil, and cover the pot mouth with a plastic film. , The disinfection time is 24h. After the formaldehyde infiltration and disinfection in the soil is complete, the plastic film is removed, and the remaining formaldehyde is evaporated, so as not to affect the survival rate of seedling...

Abstract

The invention relates to an endophytic fungus capable of increasing the chlorophyll content of casuarina. The endophytic fungus is Fusarium sp. casuarina rhizosphere fungus 46, which has been registered and preserved in the General Microorganism Center of China Microbiological Culture Collection Management Committee on June 28, 2012, and the preservation number is CGMCCNo.6310. Casuarina rhizosphere fungus 46 was inoculated in casuarina hydroponic seedlings, and according to the comprehensive evaluation of various indicators of chlorophyll, it was further confirmed that it had a promoting effect on increasing the chlorophyll content of casuarina and actually had a synergistic effect on the chlorophyll of casuarina. Functional endophytic fungi beneficial to increase the chlorophyll content of casuarina can be applied to production.

Description

technical field [0001] The invention relates to an endophytic fungus capable of increasing the chlorophyll content 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...
