| 摘 要： | 采用三元二次正交旋转组合设计方法,研究了氮磷钾肥对天鹰椒型干辣椒产量的影响,建立了相应的回归方程。结果表明,氮磷钾三种肥料中,氮肥对天鹰椒型干辣椒产量影响最大,且氮肥与磷肥两因子之间有明显的互作效应;在本试验条件下天鹰椒型干辣椒氮磷钾优化施肥方案为N:312 33～373 29kg/hm2;P2O5:69 35～103 35kg/hm2;K2O:167 38～282 62kg/hm2。

| Abstract: | With the method of the quadratic orthogonal rotational combination design with three factors, studies were conducted on the effect of different application level of N, P and K on the yield of hot cluster red pepper, and the regressive equation was established between yield and the application level. The result indicated that N had the most effect on the yield of hot cluster red pepper in NPK and there was obvious interaction between N and P. The experiment provided the best fertilization formulation which is, N:312.33～373.29 kg/hm~2;P_2O_5:69.35～103.35 kg/hm~2;K_2O:167.38～282.62 kg/hm~2. |
