内蒙古自治区有近７０％旱地，因降水有限，严重制约了旱地农业生产的发展。旱地由于单产较低，存在着巨大的增产潜力，只要提高科技水平，增加物质投入，蓄天上水，保土中水，在抗旱、节水、蓄水、保水上作文章，用宝贵的有限降水可挖掘出更大的增产潜力，因而，发展旱地... Inner Mongolia Autonomous Region has nearly 70% of the dry land, due to limited rainfall, seriously hampered the development of dry land agricultural production. Due to the low yields, drylands have huge potentials for increasing production. As long as the scientific and technological level is increased, the material inputs are increased, the water is stored in the sky, the soil and water in the soil is protected, the drought, water conservation, Can dig a greater potential for production, therefore, the development of dry land ...
