specific Embodiment approach 1

[0016] Specific embodiment one: the arbuscular mycorrhizal fungus that this embodiment improves the ability of saline-alkali resistance of Elaeoptera is Glomus intraradices (Glomus intraradices) HDSF5, which is preserved in the General Microbiology Center of China Committee for the Preservation of Microorganisms, and the preservation address is Beijing No. 3, Courtyard No. 1, Beichen West Road, Chaoyang District, the city. The preservation date is March 11, 2015, and the preservation number is CGMCC No.10607.

[0017] In this embodiment, the spores of Glomus intraradices are light yellow, nearly spherical, and have a size of 85-130 μm. The spore wall has 3 layers: L1 is colorless and transparent, easy to fall off in mature spores, 1.0-1.5 μm, stained red in Melzer's reagent; L2 is colorless and transparent, close to L1, 1.0-1.5 μm, also in mature spores Shedding; L3 light yellow-brown, layered, 2.5-3.0 μm, sometimes separated to form sublayers. The hyphae of the sporozoites a...

Abstract

The invention provides an Arbuscular mycorrhiza fungus capable of improving saline-alkali tolerance of Elaeagnus angustifolia and relates to an Arbuscular mycorrhiza fungus. The Arbuscular mycorrhiza fungus provided by the invention has a higher capacity of tolerating saline-alkali stress and provides a theoretical basis for remediation of saline-alkali soil by jointly using mycorrhiza and plants. The Arbuscular mycorrhiza fungus capable of improving saline-alkali tolerance of Elaeagnus angustifolia provided by the invention is Glomus intraradices HDSF5 and is preserved in China General Microbiological Culture Collection Center, the date of preservation is March 11, 2015, and the preservation number is CGMCC No.10607. By inoculating Glomus intraradices HDSF5, the growth of Elaeagnus angustifolia seedlings under saline-alkali stress is obviously promoted, and the content of chlorophyll, photosynthetic physiological characteristic and the activity of SOD, CAT and POD in leaf and root tissues are improved. The Glomus intraradices HDSF5 provided by the invention can tolerate the saline-alkali inhibiting effect and can promote the growth of the Elaeagnus angustifolia seedlings.

Description

technical field [0001] The invention relates to an arbuscular mycorrhizal fungus. Background technique [0002] Saline-alkali soil resources are a very important reserve cultivated land resource in my country. With the increasingly sharp contradiction between population increase and land reduction, resource shortage and ecological deterioration, people pay more and more attention to the development and utilization of saline-alkali land to alleviate the crisis and make human food supply Get a wider source. Soil salinization control is a worldwide problem. According to incomplete statistics from UNESCO and FAO, the global saline-alkali land area has reached 9.5×10 8 hm 2 , and each year at 1.0~1.5×10 6 hm 2 speed growth. Among them, the saline-alkali soil area in my country is about 9.9×10 7 hm 2 , mainly distributed in the plains of 23 provinces, municipalities, and autonomous regions in 5 large regions, including the coastal saline-alkali soil area, the Huanghuai-Hai ...
