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135 kg/hm2,密度取28万株/hm2时,绵油63可以取得约2600 kg/hm2的产量,产量比对照降低约10%,熟期推迟7d,生育期缩短40d。
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.
