赤峰市丘陵山区玉米膜下滴灌增产增效效果分析

Analysis of Yield and Efficiency Increase Effect of Corn Under-film Drip Irrigation in Chifeng Hilly Area

赤峰市丘陵山区属我国北方的典型丘陵山区地带,由于丘陵山区严重缺水,人均水量仅为全国的1/4,水资源的缺乏严重制约着当地经济的发展,农业用水为用水大户,解决农业用水大大加快了当地经济的发展。为解决水资源严重短缺问题,拟就赤峰市丘陵山区常种经济作物玉米为研究对象,采用试验和数据分析的方法,通过研究种植区土壤湿润深度、灌溉制度及肥料配合比,寻求玉米膜下滴灌最优灌溉制度及肥料配比,指导丘陵山区玉米作物的生产。

The hilly area of Chifeng city belongs to typical hilly areas of North China. The lack of water resources seriously restricts the development of local economy. The solution for agricultural water consumption will greatly accelerate the development of econo- my. In this study, the normal economic crops, maize, in the hilly area of Chifeng city, was selected as the research object, the meth- od with experiment and data analysis was used to seek the best irrigation schedule and fertilizer ratio for corn under-film drip irriga tion system to guide corn crops production in hilly area.
