定陶县位于山东省西南部,地处黄河冲积平原,属温带亚湿润季风性气候。土地平坦疏松,地力肥沃,耕性好,光热资源丰富,非常适应马铃薯二季作栽培。自1993年引种脱毒马铃薯,并与棉花等多种作物间作套种,效益较高,形成一定的种植规模,改变了县内马铃薯市场全靠外地调入的局面。1996～1998年定陶县农业局承担完成了山东省科委下达的“出口蔬菜高效配套技术开发试验”课题,52500亩春作马铃薯平均亩产2530.1kg,高产试验田300亩,平均亩产达3205.4kg。总结出春马铃薯“六早六促”高产栽培技术。一、早施肥造墒 Dingtao County is located in the southwest of Shandong Province, located in the Yellow River alluvial plain, is a temperate sub-humid monsoon climate. Land is flat and loose, fertile fertile, good tillage, light and heat resources, is very suitable for potato cultivation. Since 1993, the introduction of virus-free potatoes, and intercropping with cotton and other crops, high efficiency, the formation of a certain scale of planting, changing the county potato market entirely rely on the introduction of the field. From 1996 to 1998, Dingtao County Agricultural Bureau undertook the task of “High-efficiency Export Technology for Export Vegetable” issued by Shandong Provincial Science and Technology Commission. The average output of 52500 mu of spring potato was 2530.1 kg, and the high yield test field was 300 mu Up to 3205.4kg. Summed up the spring potato “six early six to promote ” high-yielding cultivation techniques. First, early fertilization create moisture
