摘要
[目的]探索新食葵6号在新疆霍城县生产上最佳肥料施用量，更好地发挥该品种的生产潜力。[方法]试验共设计14个施肥量处理，研究不同处理对新食葵6号经济性状、产量和经济效益的影响。[结果]新食葵6号产量（Y）与氮磷钾施肥量（N、P、K）之间的拟合回归方程为Y＝2377．8195＋48．6855N＋203．6730P＋118．4460K－0．0630NP＋6．8730NK－4．4745PK－7．2780N2－5．7855P2－6．8670K2，通过该回归方程得出新食葵6号最佳施肥量。[结论]新食葵6号最佳施 N 量为185．18 kg／hm2，最佳施 P 量为156．35 kg／hm2，最佳施K量为51．77 kg／hm2，最佳理论产量为4117．85 kg／hm2。
Abstract
Objective] To search the optimum fertilization for Xinshikui6 at Huocheng County and play the production potential.[Method] 14 different fertilizer treatments were conducted.Effects of different treatments on economic characters, yield and economic benefit of Xinshikui6 were researched.[Result]We concluded that the optimum fertilization and the fitted regression equation between yield (Y) and fertilizer (N,P, K) of Xinshikui6 was Y=2 377.819 5 +48.685 5N +203.673 0P +118.446 0K -0.063 0NP +6.873 0NK -4.474 5PK -7.278 0N2 -5.785 5P2 -6.867 0K2.[Conclusion] The best N application for Xinxhikui 6 is 185.18 kg/hm2,the best P application is 156.35 kg/hm2,the best K application is 51.77 kg/hm2 ,the best theoretical yield is 4 117.85 kg/hm2 .
