播期、密度、施肥对籽粒苋R_(104)品种籽实产量的影响

Effects of Sowing Time, Density and Fertilizer on the Grain Production of Amaranthus Caudatus R 104 .

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。

The production of R 104 grain were investigated in this experiment. The test results showed that population density was most important for grain producition and fertilizer was more important than sowing time. Best result was achived with the treatment of sowing time on the fifth of May with 8834 plants per hectare.
