采用4因子5水平通用旋转组合设计,研究了黔油14号产量与栽培因素(N、P、K、密度)间的关系,建立了各因素与产量的回归数学模型,并进行了黔油14号高产栽培优化方案分析,获得了黔油14号在黔西、安顺地区产量达170 kg/667m2以上,在遵义、黔东南产量达175 kg/667m2以上,在贵阳、黔南产量达140 kg/667m2以上的优化栽培方案。
The relationship between the yield and the cultivation factors (N, P, K, density) of Qianyou No.14 was studied by using the universal factorial design with 4 factors and 5 levels. The regression mathematical model of each factor and yield was established. The yield of Guizhou No.14 was above 170 kg / 667m2 in Qianxi and Anshun, the yield was above 175 kg / 667m2 in Zunyi and Qiandongnan, and the output in Guiyang and Qiannan was 140 kg / 667m2 more than the optimal cultivation plan.
