采用Ｌ９（３４）正交设计，通过播期、密度、施肥三个因素处理试验，探讨了对籽粒苋籽实产量的影响。试验结果表明，密度是影响籽实产量的主要因素，其次是施肥量，最佳处理组合是Ａ２Ｂ１Ｃ２，播期为５月１５日，密度为８３３４０株／ｈｍ２，籽实产量达５．００４ｔ／ｈｍ２。
Using L9 (34) orthogonal design, the effects of sowing date, density and fertilization on the yield of grain amaranth were studied. The results showed that density was the main factor affecting the seed yield, followed by the amount of fertilizer application. The best treatment combination was A2B1C2. The sowing date was May 15, the density was 83340 plants / hm2, and the seed yield was 5.004 t / hm2.
