Method for greening desert and system thereof

Abstract

The invention provides a method for greening desert and a system thereof. The method comprises the steps: digging grooves on the ground; laying ecological cloths on the ground and in the grooves; and placing ecological compound bags in the grooves. The inventive method for greening desert and system thereof adopt cross network grooves to construct lattice array of sand barrier pits by the ecological compound bags and resist ultraviolet rays by the non-woven ecological bags; completely exerts the functions of collecting water by films and reducing evaporation of water and adds suitable amount of organic fertilizers and the like to ensure the ecological compound bags to be beds for the growth of plants in small areas so as to collect nutrients and water, which are rationally distributed to plants. Suitable amount of plant seeds which are suitable for growth locally is mixed and suitable amount of plants is sowed outside the ecological bags, thus effective preventing loss of water and greatly increasing the greening efficiency and effect of desert.

Description

technical field [0001] The invention relates to a greening method, in particular to a desert greening method and system thereof. Background technique [0002] my country is one of the countries with serious desertification hazards in the world. The existing desertification and desertification land area is more than 1.5 million square kilometers, accounting for almost one-sixth of the country's land area. If deserts and Gobi are included, it almost exceeds the total arable land area of ​​the country. From the late 1950s to the mid-1970s, China's desertified land was spreading at an average annual rate of 1,560 square kilometers; from the mid-1970s to the late 1980s, it was accelerating at an average annual rate of 2,100 square kilometers; in the 1990s, Accelerating at an average annual rate of 2,460 square kilometers. [0003] The reduction of river water volume, cut-off, and decrease in rainfall resulted in desertification of the land, and then turned into a desert after a...

Problems solved by technology

However, feasibility does not represent perfection. Experts have found through decades of investigation and research that many traditional desert greening technologies are imperfect. Because many desert control technologies rely on the resources of the desert itself for governance and greening, It can be said that it is not to create desert greening resources, but to plunder desert greening resources
