弄清中低产田的分布、类型等,利于针对不同土壤的障碍因素提出有效的改良措施,提高耕地的综合生产能力,使耕地成为可持续发展资源,为农业健康有序发展提供保障。舞钢市地处伏牛山区与黄淮平原交界处,中低产田分布面积大,已成为制约全市农业生产发展的重要因素。2010年在对全市耕地进行地力评价的基础上,参照《全国中低产田类型划分与改良技术规范(NY/T310-1996)》,划分出全市的中低产田的类型,弄清其分布状况。针对不同类型的中低产田采取兴修水利设施、增施有机肥、秸秆还田、测土配方施肥等措施加以改良,提高耕地地力。
To clarify the distribution and types of middle and low-yielding fields is conducive to the improvement of the barriers to different soils and to improving the comprehensive productivity of arable land so that arable land can become a resource for sustainable development and provide a guarantee for a healthy and orderly development of agriculture. Wugang City is located at the junction of Funiu Mountain and Huanghuai Plain, with a large distribution area of medium and low yield fields, which has become an important factor restricting the development of agricultural production in the whole city. In 2010, based on the evaluation of the cultivated land in the city, based on the “Classification and Improvement of Medium and Low Yield Fields in the Country (NY / T310-1996)”, the types of middle and low yield fields in the whole city were classified and their distribution was clarified. For different types of low-yielding farmland to take to build water conservancy facilities, increase the application of organic fertilizer, straw, soil testing and fertilizer and other measures to be improved to improve soil fertility.
