First of all, of course, we must protect the environment. Planting trees and all kinds of trees are the fundamental methods. Trees can prevent wind and fix sand, maintain soil, fundamentally improve soil and prevent sand areas from expanding further. Secondly, we should pay attention to reducing man-made environmental and ecological damage, returning farmland to forests, protecting forest land and prohibiting deforestation for land reclamation. Finally, we can learn from the method of straw grid sand barrier. Grass grid sand barrier: it is a sand prevention method to prevent wind, fix sand and protect water. Use straw, straw, reed and other materials to form a chessboard in the desert. Straw checkered sand barriers can make the ground rough, reduce the wind, intercept rainwater and other moisture, increase the water content of the sand layer, which is beneficial to the survival of sand-fixing plants.

In 1950s and 1960s, when China built the Baolan Railway, the Baolan Railway crossed the Tengger Desert from Shapotou, Ningxia Zhongwei. In order to protect the Baolan Railway from being swallowed up by the desert, Zhongwei people invented the method of sand fixation in the process of fighting against the desert. The specific method is to spread wheat straw and rice on the middle grass with a shovel, and about 50㎝ of the grass is square. Because wheat straw affects the small air circulation during direct blowing, the sandbox will not be affected by the wind, so the sand is fixed. Zhongwei people also take water from the Yellow River and plant grass and shrubs on the grass fence.

After decades of management, a thin layer of soil has been formed on the desert in the desert management area, but it is easy to be destroyed due to the harsh natural environment. Ancient people used reeds and sand to build the Great Wall, which lasted for thousands of years and still stands today. The border guards built walls with straw and sand and transformed them into old barracks. Keeping the border and helping the green is to adopt the wisdom of the ancients. How many years does wheat straw control desert corrosion? I think it is more than ten years, decades or even longer!
