中低产田指农作物产量低下的耕地。中低产田生产潜力大 ,对其改造的经济和生态效益均大于新垦荒地 ,在水少地多和生态脆弱的干旱区尤其如此 ,对其加强研究与改造是十分重要的。阿勒泰地区中低产田分布广 ,面积大 ,成因复杂 ,在新疆有较好的代表性。本文论述阿勒泰地区中低产田的分布、类型 ,分析中低产田的成因 ,并提出改造措施。
Middle and low yield farmland refers to the crop yield is low. The middle and low yielding fields have great potential for production, and economic and ecological benefits for their transformation are greater than newly reclaimed wasteland. This is especially true in arid and arid areas where water is scarce and ecologically fragile, and it is very important for them to strengthen research and transformation. The middle and low-yielding fields in Altay Prefecture are widely distributed, large in area and complex in origin, and have good representation in Xinjiang. This article discusses the distribution and types of middle and low-yielding fields in the Altay region, analyzes the causes of low and middle-yielding fields, and proposes measures for improvement.
