根据Troug—stanford施肥公式,对马铃薯的测土施肥进行了研究。其结果如下: 相关性研究和田间校验试验表明,在内蒙西部平原地区的冲积土,土壤速效磷最好的浸提液是0.5MNaHC_3,而1.8NNaOH水解氮的方法也是适宜的。马铃薯对土壤水解氮的利用系数变动在46％到65％之间;对土壤全氮的利用系数变动在2.9～5.1％之间;对土壤速效磷的利用系数变动在30—140％之间。每生产1000公斤薯块,三要素的吸收量是:N4.38±0.36(公斤);P0.79±0.04(公斤);k6.55±1.70(公斤)。马铃薯对氮肥的利用率是30—40％;对磷肥的利用率是15—20％。据上述参量,按照土壤速效养分含量和马铃著产量指标,获得了氮磷肥的推荐。此外,根据马铃薯基础产量,提供了氮磷肥的推荐 According to Troug-stanford fertilization formula, potato soil testing and fertilization were studied. The results are as follows: The correlation study and field test showed that the best leachate of soil available phosphorus was 0.5MNaHC_3 in alluvial soil in the western plain of Inner Mongolia, and the method of hydrolyzing nitrogen by 1.8NNaOH was also suitable. Potato utilization of soil hydrolyzable nitrogen fluctuated between 46% and 65%, soil total nitrogen utilization coefficient fluctuated between 2.9 and 5.1%, and soil available phosphorus fluctuated between 30 and 140%. Each production of 1000 kilograms of tubers, the absorption of the three elements are: N4.38 ± 0.36 (kg); P0.79 ± 0.04 (kg); k6.55 ± 1.70 (kg). Potato utilization of nitrogen is 30-40%; utilization of phosphate fertilizer is 15-20%. According to the above parameters, according to the available soil nutrient content and yield indicators, access to nitrogen and phosphorus fertilizer recommendations. In addition, nitrogen and phosphorus recommendations are provided based on potato yields
