Method for preventing desertification by artificial forest

Abstract

The method for controlling desertification by using artificial tree includes the following steps: 1. preparing artificial tree: using plastics, rubber, nylon or glass fibre reinforced plastics as rawmaterial to prepare artificial tree which is identical to real tree in three form, branches, leaves and colour, and its underground portion root system posseses main root, side root and hair root, its root system has 2-3 layers; 2. planting artificial trees; pit planting or planting in rows; 3. planting natural trees: planting natural arbor species and shrub species in gaps between artificial trees; and 4. taking out artificial trees; when the vegetative cover rate is up to above 50%, taking out artificial trees.

Description

(1) Technical field:

[0001] The invention relates to a method for afforesting deserts and barren hills. (two) background technology:

[0002] Desertification is spreading all over the world, and the extended areas are mainly arid, semi-arid and semi-humid areas. One of the root causes is the drought and water shortage in these areas. If trees are planted in a large area, a large amount of water will inevitably be dissipated. A tree is equivalent to a small water pump. When the ecological environment has not yet formed or recovered to the conditions for large-scale tree planting, planting a large number of trees will not only consume limited water resources in arid areas, but also make it difficult for trees to survive, resulting in a waste of manpower and material resources. . my country's desertification prevention and control has been in an embarrassing situation of local improvement and overall deterioration for decades. In addition to human effects, the main reason for...
