采用二次通用旋转回归组合设计研究了不同栽培因素 (密度、氮、磷、钾、硼施用量 )与“黔油 1 0号”产量及构成因素之间的关系。其研究结果表明 :氮、磷肥施用量和密度是主导因素 ;各栽培因素通过对产量构成因素发生作用而影响产量 ;各栽培因素与产量的关系为Y =a +bx +cx2 ;与单株有效角果数、有效分枝数、角粒数、千粒重间的关系为Y=a +bx ;通过回归分析进一步明确了“黔油 1 0号”的最适播种密度为 1 1 .6 0 5 8～ 1 2 .80 5 8万株 /hm2 ,N ,P2 O5最适施用量分别为 1 72 .45 6 7～ 1 94.5 487kg/hm2 和 1 1 2 .46 97～1 2 6 .877kg/hm2 ,K2 O的最适用量为 74.6 0 36～ 92 .6 1 1 6kg/hm2 ;硼砂的最适施用量为 9.71 5 5～ 1 1 .5 1 5 5kg/hm2 。在这一组合措施条件下 ,“黔油 1 0号”可获得 2 45 0 .0 0kg/hm2 以上的产量
The relationship between yield and components of “Qianyou 10” was studied by using quadratic universal rotation regression combination design with different cultivation factors (such as density, N, P, K and B). The results showed that nitrogen and phosphorus fertilizer rates and densities were the dominant factors. The cultivation factors affected the yield by affecting the yield components. The relationship between cultivation factors and yield was Y = a + bx + cx2. The results showed that the optimal sowing density of “Qianyou 10” was 1 1 .6 0 5 8 by regression analysis ~ 1 2 .80 58 000 plants / hm2, N, P2 O5 optimum application rates were 1 72.45 6 7-1 94.5 487kg / hm2 and 112.446 97-162.8877kg / hm2, The optimum dosage of K2 O is 74.6 0 36 ~ 92 .6 1 1 6kg / hm2. The optimum dosage of borax is 9.71 5 5 ~ 1 1 .5 1 5 5kg / hm2. Under this combination of measures, “Guizhou Oil No. 10” can obtain more than 2 045 kg / hm2
