Introduction to sandy land cultivation: According to relevant data, there are now more than 48 million acres of sandy land in the Horqin Grassland, ranking first among the four largest sandy lands in my country, and expanding outward at a rate of more than ten meters per year. In order to prevent the desertification of grasslands over time, the state has promulgated the policy of returning farmland to forest and grassland, and returning grazing land to grassland, and adopted measures such as artificial grass planting, flood diversion and irrigation, and grassland enclosure to protect grassland cultivated land, and achieved good results.
