Abstract

The invention provides a desert greening method, which belongs to the field of desert treatment. The method specifically includes: setting a windbreak and sand-fixing area at the edge of the sandy land to be greened to form a greening area; setting a water storage cellar at the sand-fixing barrier; Planting belts and sand-fixing belts are set parallel to each other in the greening area; the planting belts are strip-shaped grooves, and after the improvement agent is laid on the bottom of the grooves, they are plowed and leveled; There is a row of planting holes in its length direction; after transplanting the planting pots containing saplings cultivated indoors on the planting holes, the strip grooves are filled, and the surface after filling is not higher than the top edge of the planting pots; Apply sand-fixing agent on the surface of the sand-fixing belt, and water the fixed planting pot every 1-2 months until the height of the sapling is higher than 3 meters. This application adopts a series of compound measures such as artificial greening, sand fixation, and improvement agent restoration, and various measures are used together to provide a guarantee for the self-restoration and greening of the sandy land.

Description

technical field

[0001] The invention relates to the field of desert greening, in particular to a desert greening method. Background technique

[0002] There is a large area of ​​desertified land in northern my country. According to statistics, it is about 1.5 million square kilometers. What's more serious is that desertification is gradually increasing, which poses a great threat to the ecological environment in northern my country. At the same time, it also poses great harm to the industrial and agricultural production and people's life in related areas, and seriously affects the development of social economy.

[0003] Based on the seriousness of desertification hazards, the use of artificial vegetation to prevent and control sand damage has a history of decades, and it is also internationally recognized as one of the most effective methods for ecological reconstruction of sandy areas. This method is mainly carried out by planting drought-tolerant plants in deserts, such ...
