Description
Technical field
The present invention relates to land remediation field, and in particular to a kind of method that utilization arbuscular mycorrhiza repairs saline-alkali bare land.
Background technology
Saline and alkaline soil resource is a kind of critically important standby cultivated land resource of China, with population increase and soil reduction, resource
Being becoming increasingly acute of contradiction of shortage and ecological degeneration, people increasingly pay attention to developing salt-soda soil alleviating crisis, make the mankind
Food supply obtain more wide source.It is a worldwide problem that the salinization of soil, which is administered,.According to the United Nations's education, science and culture group
The incomplete statistics with food and agricultural organization is knitted, global saline alkali land area is up to 9.5 × 108hm2, and it is annual with 1.0-1.5 × 106hm2
Speed increases.Wherein, China's saline-alkali soil area is about 9.9 × 107Hm2, is distributed mainly on 23 provinces, city, the autonomies in 5 Ge great areas
The Plain in area, including coastal saline-alkali Tu Qu, Huang-Huai-Hai plain saline-alkali soil area, the semiarid saline-alkali soil area in northwest and arid saline-alkali soil area
And northeast saline-alkali soil area.Meanwhile, the salinization of soil triggers many ecological environment problems, and such as soil erosion, desertification of land is gloomy
Woods and grassland resources are reduced, and bio-diversity is reduced etc..Seek active and effective measure preventing and treating and improvement salt affected soil, drawn
The highest attention of scholar and governments at all levels is played.It is that the focus studied at present is asked using microorganism-plant combined repair saline-land
One of topic.
Forest biological technology of mycorrhiza gradual perfection, many national in the screening of effective VA Mycorrhizal Fungi in the world during the nearly last ten years
On the basis of, it is directed to the development of efficient VA Mycorrhizal Fungi preparation and the research and application of Mycorrhizal new technology.In mycorrhizal fungi, with clump
Mycorrhizal fungi distribution is most wide, studies also more, has especially at home and abroad carried out many utilization AMFs and plant in recent years
The mutualistic symbiosis relation of thing strengthens the research of adaptive faculty of the plant in salt affected soil.
The content of the invention

Transplantation of seedlings is got on, and cultivates processing 30-50d；
(2) above-mentioned arbuscular mycorrhiza strain is added to the water, sterile soil is added while stirring, become certain sticky
The mud of degree, by it is above-mentioned handled through cultivation after host plant seedling dig out, its root is impregnated into mud, infiltrating time is
10-15s；
(3) plantation hole is dug on saline-alkali bare land, the plantation pit density is every 100 square metres of 4-6 rows, often row 5-8, institute
Plantation hole depth is stated for 20-30cm, is laid in plantation hole surrounding with careless grid laying every salt deposit in plantation hole bottom with clinker every salt
Layer, fertilizer of being splashed into plantation hole bottom enters the host plant sprigging that root infiltrates mud in plantation hole, with configuration
Good mixed soil covers its root, and hole is finally filled out with salt affected soil, pours permeable.
Preferably, arbuscular mycorrhiza strain includes Glomus versiforme (Glomus versiforme), rubbed in the step (1)
Western sacculus mould (Glomus mosseae), Glomus etunicatum (Glomus etunicatum) and the mould (Glomus of clumping sacculus
aggregatum)。
Preferably, in the step (1) sterilizing methods of sterile soil be by soil in high-pressure sterilizing pot 121 DEG C it is continuous
Sterilize 2h.
Preferably, fertilizer includes human and animal excreta, microbial manure and inorganic fertilizer in the step (3).
Preferably, in the step (3) clinker lay every salt deposit thickness be 4-8cm.
