近两年来,马铃薯在山东省嘉祥县的种植规模不断扩大,为探索嘉祥县潮壤土上马铃薯的高产施肥技术,结合测土配方施肥工作,进行了马铃薯钾肥总控制试验。100%钾肥区比无钾肥区增产35.3%,推荐配方施肥区比无钾肥区增产37.2%,100%钾肥区比无钾肥区亩增加经济效益1085.7元。马铃薯当季贡献率为26.08%。试验表明在嘉祥潮质土壤上种植马铃薯增施钾肥和测土配方施肥均能起到很好的增产增收作用。
In the recent two years, the planting scale of potato in Jiaxiang County of Shandong Province has been continuously expanding. In order to explore the high-yield fertilization technique of potato on the loamy loam in Jiaxiang County, the potash fertilizer total control experiment was carried out in combination with soil testing and formula fertilization. 100% potash increased 35.3% compared with no potash, and the recommended formula fertilization was 37.2% more yield than the non-potash, and the economic benefit was 1085.7 yuan more than the 100% potash without potassium. The contribution rate of potato season is 26.08%. Experiments show that planting potatoes in Jiaxiang tidal soil increased fertilization of potash and soil testing and fertilization can play a good yield and income.
