Green desert planting structure and method of growing plants in desert

Abstract

The invention discloses a green desert planting structure and a method for planting plants in a desert. According to the planting structure, planting pits are dug downwards from the desert surface, leakage prevention and water retention layers are arranged on the surfaces of the planting pits, after the plants are planted in the planting pits, the planting pits are backfilled with desert soil, and ground surface wind prevention layers are arranged on the surfaces of the planting pits, wherein the content of sandy soil with the particle size of 0.075-60 mm in the desert is higher than 50%, the leakage prevention and water retention layer and the ground surface wind prevention layer are both obtained through processing of microbial anti-seepage reinforcement liquid, microorganisms in the anti-seepage reinforcement liquid are aerobic bacteria, the permeability coefficient ratio of the desert with the leakage prevention and water retention layers to a desert without the leakage prevention and water retention layers is smaller than 5%, and the ground surface wind prevention layers cannot be blown away on the condition that the highest wind speed is 20 m / s. Accordingly, the dependent microbial reaction process is the process existing in a soil mass ecological environment and cannot pollute the environment; by adopting a microorganism-plant combined desertification control technique, the survival rate is higher compared with the technique that only the plants are planted.

Description

technical field [0001] The invention relates to a desert planting structure and a planting method in the desert, in particular to a green desert planting structure and a method for planting plants in the desert, belonging to the technical field of desert control. Background technique [0002] Desertification is a worldwide ecological environment problem. According to incomplete statistics, deserts and desertified land account for 55% of Africa, 19% of North and Central America, 10% of South America, 34% of Asia, 75% of Australia, and 2% of Europe. China's desertification land area is 2.622 million square kilometers, accounting for 27.4% of the country's land area. Nearly 400 million people are affected by desertification. At the same time, the annual direct economic loss caused by desertification hazards reaches 120 billion yuan. [0003] At present, scholars' research on desertification mainly focuses on sandy desertification. Commonly used means of controlling deserts in...

Problems solved by technology

But the simple planting of trees is very difficult, the depth of plant burial is very large, the survival rate of plants is very low, the effect is slow, and a lot of manpower and material resources are required.

Sand barriers and grass grids are effective quickly, but the investment is relatively large, and it is difficult to use them on a large scale

There are also new methods of soil surface crusting technology, including chemical, physical and biological crusts. Pure physical and chemical crusts are very fragile and unstable, and chemical crusts also pollute the surrounding environment to a certain extent.

The biological crust is a large amount of mucus produced by the growth of bacteria, fungi, blue-green algae, etc. These bacteria with viscous appendages and viscous liquids form crusts through cross-linking with algal substances, but this method has certain environmental impacts. requirements, and the crust grows slowly and takes effect slowly
