Abstract

The invention discloses a repeatedly utilized grass grid sand fixing method. The method relates to a new grass grid sand-protecting barrier method and comprises the steps of: bundling up plant straws into grass bundles; paving the plant bundles on a sand surface to form a grid shape; fixing the plant straws on the sand surface by using a fixed drill rod; lifting the plant straws on the ground surface through a hook on a rake when lots of sands are accumulated in the square grids, wherein the anti-wind and sand-fixing capability of the grass grid sand-protecting barriers is recovered. The method is used for fixing flowing sand surfaces, can prevent hazards of sand storms of oasis cities and towns and engineering construction, can help afforestation in quicksand and can improve rate of survival of nursery stocks. The method can be widely applied to extremely droughty desert areas. If the straws are subjected to good preservative treatment, the method is also applicable to other windy and dusty areas with relatively great rainfalls. The repeatedly utilized grass grid sand fixing method solves the difficulty that the grass sand-protecting barrier after being buried in sands cannot be utilized repeatedly, is capable of saving raw material pre-treatment expense, enhancing erosion resistance of the straws and simplifying site construction besides fully utilizing the plant straw resource, and can be widely applied to the protection and treatment of hazards of sand storms in the extremely draughty desert areas.

Description

technical field [0001] The invention relates to sand prevention and sand control technology, in particular to a reusable grass grid sand fixation method. Background technique [0002] Desertification is one of the major global environmental problems at present. It directly threatens the foundation of production and development of human society, resulting in a continuous decline in land productivity. According to statistics, 3.6 billion hectares of arable land and pastures around the world are threatened by desertification, and desertification causes direct economic losses of more than 42 billion U.S. dollars every year. [0003] Numerous desertification prevention and control methods have been formed at home and abroad. According to the prevention and control principles, they can be divided into mechanical sand control, chemical sand control, and biological sand control. Among them, mechanical sand control has the advantages of low cost and quick results. Grass grid sand ba...
