摘要: 为内蒙古地区马铃薯生产中钾肥施用量提供理论指导,在内蒙古达尔罕茂明安联合旗进行了钾肥效应试验。结果表明:在氮磷肥处理一致的情况下,随施钾量增加,马铃薯农艺性状,经济效益均有所提高。当钾肥施用量达到10kg/667m2时,产量2378.6kg/667m2,每穴薯重0.642kg/穴,大小薯比例5.25,水分生产效率9.92kg/mm,经济效益2348.6元/667m2均达最高。

Abstract: To direct potassium fertilization for potato production in Inner Mongolia,the experiment of potassium fertilizer effects on potato was conducted at Damaoqi Inner Mongolia.The result revealed that:on the basis of same amount of nitrogen and phosphorus fertilizer,the agronomic traits and economic benefits of potato are all improved with the application of potassium amount increasing.When the application of potassium amount was 10kg/667m2,the total yield(2378.6kg/667m2),the weight per hole(0.642kg/hole),the potato size proportion(5.25),the water productivity efficiency(9.92kg/mm),and the economic benefits(2348.6Yuan/667m2) were the highest.
