Description
Technical field
The present invention relates to a kind of pattern of farming and implantation methods, more particularly to a kind of desert planting structure and planted in desert
The method of plant is planted, belongs to method of tackling desert field.
Background technology
Desertification is a global ecological environment problem.According to incompletely statistics, desert and Desertification Soil are in Africa
55% is accounted for, North America and Sino-U.S. account for 19%, and South America accounts for 10%, and Asia accounts for 34%, and Australia accounts for 75%, and Europe accounts for 2%.It is Chinese waste
Desertization land area is 262.2 ten thousand square kilometres, accounts for the 27.4% of national territorial area, nearly 400,000,000 population is influenced be subject to desertification, together
When, every year because desertification endanger caused by direct economic loss up to 120,000,000,000 yuan.
At present, in terms of research of the scholar to desertification is concentrated mainly on land sandy desertification.Common Desert Control
Means have plant afforestation, sand-protecting barrier, straw checkerboard barrier etc..But simple tree planting is difficult, plant length of embedment needs very big, plant
Survival rate is very low, and slowly effect is, it is necessary to put into substantial amounts of man power and material.Sand-protecting barrier, straw checkerboard barrier are quick, but input also compares
Greatly, it is difficult to which large area uses.Emerging means also have soil surface skinning technology, have chemistry, physics and biological breadcrust, merely
Physics and chemical skinning it is very fragile and unstable, while chemical skinning also has surrounding environment certain pollution.And biology knot
Skin is that a large amount of mucus are produced in the growth by bacterium, fungi, blue-green alge etc., these have the appendicular thalline of viscosity and viscosity
Liquid is combined into skinning by the crosslinking with algae substances, but the method has environment certain requirement, and skinning is slow-growing,
Slowly effect.
The content of the invention
Goal of the invention：In order to overcome problem existing for control of desert in the prior art, the first object of the present invention is to provide
One kind utilizes naturally occurring microbial reaction consolidation sandy soil structure in natural environment, and the sand of good ecological environment is provided for plant
Unconcerned pattern of farming；The second object of the present invention is to provide the method for the planting plants in the desert.
Technical solution：Desert planting structure of the present invention, plantation hole is opened up downwards from desert surface, and in the plantation
The part surface in hole is set up defences infiltration layer, then backfills desert soil after planting plants in plantation hole and to set earth's surface on its surface windproof
Layer, wherein, sand content >=50% of particle diameter≤0.075mm in desert, impervious barrier and earth's surface wind prevention layer are added by microorganism antiseepage
Solid-liquid handles to obtain, and the microorganism in the microorganism anti-seepage reinforcing liquid is facultative anaerobic bacteria, impervious barrier and infiltration layer sand of not setting up defences
The ratio between unconcerned infiltration coefficient is less than 5%, and earth's surface wind prevention layer is not dispelled in the case where maximum wind velocity is 20m/s.
The desert planting structure of the present invention is suitable for fine grained desert, and the permeable breathable of desert sand is poor, corresponding to use
