【摘要】通过"3414"田间试验,研究不同氮磷钾水平对马铃薯产量的影响。经统计分析获得冷棚马铃薯三元二次肥料效应函数为Y=1563.74+56.93N+116.45P+4.84NP+7.37NK-9.42PK-6.31N2-5.92P2,求得马铃薯最高产量施肥量为:N=12.05kg/667m2,P2O5=9.42kg/667m2,K2O=6.72kg/667m2;最佳产量施肥量为:N=11.58kg/667m2,P2O5=8.39kg/667m2,K2O=7.19kg/667m2。更多还原

【Abstract】 Through ‘3414’ field experiment, the yields of potato were studied at different levels of N, P, K. By statistical analysis three-factor quadratic functions of the plastic film covered shed potato fertilizer were obtained:Y=1563.74+56.93N+116.45P+4.84NP+7.37NK- 9.42PK-6.31N2-5.92P2. The highest production of potato fertilizer was N=12.05 kg/667 m2, P2O5=9.42 kg/667 m2, K2O=6.72 kg/667 m2 and best production of potato fertilizer was N=11.58 kg/667 m2, P2O5=8.39 kg/667 m2, K2O=7.19 kg/667 m2.更多还原
