Although the quality of day lily of Qingyang city is best in the whole country, the day lily is planted fragmentarily at the residence, roadside, bank of the canal, low bank of border, and district of field, and also do not form the best product region and suitable planting technology. The product region environment condition of day lily in Qingyang city was analyzed from2001 to 2005, the advantageous product regions of day lily in Qingyang city was planned, and planting technology of day lily was studied. The main result of study were as follows:First. Qingyang city belongs to dry agricultural region, its solar radiation is quite rich, but the water resources is short in all district, the agricultural production depends on the natural precipitation.

生产的黄花菜质量在全国名列前茅，但是庆阳的黄花菜多在宅旁、路边、渠岸、田边地埂等零星地进行生产，没能形成优势产区，对栽培技术研究也较少。2001年～2005年我们分析评价了庆阳市黄花菜产区环境，进行了黄花菜优势产区区划和旱作栽培技术研究，主要研究结果如下： 1 庆阳市太阳辐射比较丰富，水资源缺乏，农业生产靠天然降水，属旱作农业区，河流大部分水质较好，灌溉水源基本未受到污染。
