Problems solved by technology
However, due to dry desert conditions, extreme heat, lack of water, and unfavorable human management, it is difficult for the trees to survive, resulting in an increasing desert area.
[0003] The existing desert control method is to directly spray coagulant or cover plastic film on the desert, which can keep the sand from being blown by the wind in a short period of time, but it consumes a lot of manpower and financial resources, and is not conducive to afforestation, and it is difficult to carry out large-scale development. Governance work
There is also a method of adding plant seeds in the covering layer. Because the covering layer itself cannot retain water, it is necessary to supply water to the covering layer for a long time to keep it moist. However, the climate in the desert is very hot and dry, and it is necessary to keep the covering layer moist. very difficult

Embodiment Construction
[0016] 1. Collection of covering layer materials: collect urban waste and other raw materials containing organic matter, classify and clean them, and sort out harmful substances such as plastic, metal, glass, etc.;
[0017] 2. Crushing and stirring: crush the sorted raw materials, add coagulant, chemical raw materials required by plants, water, and put them into the mixer for stirring;
[0018] 3. Molding: put the stirred raw materials into a molding machine, press and shape them once, and press them into squares, rectangles, etc. that can be spliced together, and the top of the covering layer should be raised;
[0019] 4. Waterproof treatment: brush or cover a layer of waterproof material on the surface of the dried covering layer.
[0020] Applicable geographical environment: the edge of the desert, the desertified area with an annual rainfall of more than 100 mm and the area with a gentle slope.

The invention relates to a desert planting method, characterized in that covers a cover at edge of desert which can hold sand, water, fertilizer and temperature, in geometry shape, while the top of the cover is protruded and the cover is coated with a layer of waterproof material and the cover contains needed nutriment and chemical elements of plant, to supply water and nutriment to later planted plants. The inventive cover can be made from life waste and organic material, which contains chemical materials as potassium, magnesium and calcium needed by plants. The invention can cultivate plants in desert to protect former ground surface, and hold the plant position in cover, with which later planted plants can grow easily. The invention can be used to cultivate trees in desert first and then plant other dry-resistant farm crops to be used in desert edge and semi-dry area.
Description
1. Technical field [0001] The invention relates to a desert greening method, which belongs to the technical field of environmental protection and environmental greening. 2. Background technology [0002] Land desertification has become a very serious natural disaster faced by people, especially China is one of the countries most seriously affected by desertification. Every year, the Chinese government invests a lot of manpower and financial resources in desert control and afforestation. However, due to dry desert conditions, extreme heat, lack of water, and unfavorable human management, it is difficult for the trees to survive, resulting in an increasing desert area. [0003] The existing desert control method is to directly spray coagulant or cover plastic film on the desert, which can keep the sand from being blown by the wind in a short period of time, but it consumes a lot of manpower and financial resources, and is not conducive to afforestation, and it is difficult to...
