| 摘 要： | 运用均匀设计法研究不同氮、磷、钾配施对马铃薯产量的影响。以马铃薯品种尤金为供试材料,在田间条件下以氮、磷、钾施用量和配比作为变量,马铃薯产量为目标函数建立方程。结果表明:氮、磷、钾需求量,钾肥>氮肥>磷肥,符合马铃薯需肥规律。通过对氮、磷、钾肥与产量的施肥模型进行频次分析得出,黑龙江省哈尔滨地区马铃薯田施肥量:纯N为157.95～162.61 kg/hm2,P2O5为30.59～34.08 kg/hm2,K2O为191.30～204.28 kg/hm2。

| Abstract: | The uniform design was used to research the effects of different NPK fertilizer combinations on the yield of potato in Heilongjiang province.Equations were established using NPK fertilizer combinations as the decision variable and the potato yield as the objective function for the potato variety Youjin.The results showed that the demand for NPK was in the order: potassium > nitrogen > phosphate,consistent with the rule of potato fertilizer requirement.Based on the fertilization model frequency analysis of N... |
