| 摘 要： | 试验采用二次正交旋转组合设计，研究了不同施肥量和种植密度对11月上旬直播的棉油63产量的影响。结果表明，密度的影响大于施肥量；当施肥量取135kg／hm^2，密度取28万株／hm^2时，绵油63可以取得约2600kg／hm^2的产量，产量比对照降低约10％，熟期推迟7d，生育期缩短40d。

| Abstract: | The effect of density and fertilizer level on mianyou 63, which were sown at November 7th, was studied with quad- ratic rotational regression combination design. It showed that the effect of planting density is bigger than fertilizer level. The yield of mianyou63 can reach 2600 kg/hm2 when it was planted by 280, 000 seedling/bin2 and fertilized nutrition by 135 kg/ hm2. Compared with the control, maturity of the best combination delayed only 7 days ,yield decreased only by 10% while growing time reduced by 40 days. |
