摘 要：
[目的]探讨密度和氮磷钾肥料不同配比对马铃薯品种大西洋产量的影响。[方法]采用4因素5水平二次回归旋转组合设计,在哈尔滨地区的土壤条件下,通过田间试验,以密度(X1)、尿素(X2)、二铵(X3)、硫酸钾(X4)4项农艺措施为决策变量,以公顷产量为目标函数,建立产量数学模型。[结果]试验表明,影响鲜薯产量的顺序是氮肥>钾肥>磷肥>密度;经计算机模拟寻优,鲜薯产量大于28.72 t/hm2的优化组合为密度64 482~70 518穴/hm2、尿素267.23~292.21 kg/hm2、二铵232.94~277.06 kg/hm2、硫酸钾418.20~462.75 kg/hm2。[结论]研究可为黑龙江地区提高加工专用马铃薯品种大西洋的产量、改善土壤状况、防止过量施肥照成环境污染提供参考依据。

摘 要：
[Objective] To discuss effects of density and different proportion of nitrogen,phosphorus,potash on yield of potato variety Atlantic. [Method]Under the soil condition of Harbin region,adopting four factors,five levels of quadratic regression rotation combination design,considering four agronomic measures of density( X1),urea( X2),diammonium( X3),potassium sulphate( X4) as decision-making variables,through field experiment,the mathematical model of prwoduction was established with hectare as objective function. [Result]The result shows that the sequence of influencing the production of fresh potato is nitrogen > potash > phosphorus > density; optimum combination of fresh potato yields more than 28. 72 t / hm2 is density 64 482- 70 518 holes / hm2,urea 267. 23- 292. 21 kg/hm2,diammonium 232. 94-277. 06 kg / hm2,potassium sulfate 418. 20- 462. 75 kg/hm2 using the computer simulation optimization. [Conclusion] The study can provide reference basis for improving yield of potato variety Atlantic,perfecting soil condition,preventing environmental pollution caused by excessive fertilization.
