| 摘 要： | 目的]探索黔花生二号的丰产栽培技术模式。方法]采用二次通用旋转回归组合设计研究黔花生二号产量与主要栽培措施（密度、氮、磷、钾）间的数量关系,并建立各因素与产量指标间的数量模型。结果]黔花生二号获得高于4 305.3 kg/hm2的丰产栽培技术措施是：播种密度为28.29×104～28.69×104株/hm2;尿素施用量为136.875～163.125 kg/hm2;过磷酸钙施用量为423.750～476.250kg/hm2;硫酸钾施用量为136.875～163.125 kg/hm2,其中N∶P2O5∶K2O=1∶2.08∶2.17。结论]影响黔花生二号产量的主要因子是密度和钾肥,其次是磷肥和氮肥。

| Abstract: | Objective]The research aimed to study the high yield cultivation techniques of Qian Peanut No.2.Method] The numerical relationship between yield of Qian Peanut No.2 and main cultivation measures(density,N,P,and K) were studied by quadratic general rotary unitized design.And the numerical model about each factors and yield index was established.Result]The results showed that the high yield cultivation techniques of Qian Peanut No.2 with yield over 4 305.3 kg/hm2was sowing density of 28.29×104-28.69×104 plant/hm2,urea and K2SO4 amount of 136.875-163.125 kg/hm2,calcium superphosphate amount of 423.750-476.250 kg/hm2,with N∶P2O5∶K2O=1∶2.08∶2.17.Conclusion]The main factors which affected the yield of Qian Peanut No.2 were density and K fertilizer,followed with P and N fertilizer. |
