摘要
通过对晋谷21 号设置4 个密度和4 种留苗方式,研究其农艺性状及产量表现,结果表明,密度是影响产量的显著因素,随着密度和留苗方式的增加,晋谷21 号穗长和穗粗呈降低趋势,产量在 2～3 株时表现最佳.晋谷 21 号旱地最佳种植密度为 12 000株/667 m2,留苗方式为2～3 株.
Abstract
The agronomic characters and yield performance of'Jingu 21'millet were investigated by setting four densities and four methods for retaining seedlings.The results showed that planting density was a significant factor affecting yield.The ear length and ear diameter decreased with the increase of plant density and seedling retaining pattern,and the highest yield was obtained under the 2～3 plants per 667m2 condition.The optimal planting density for'Jingu 21'millet was determined to be 12 000 plants per 667m2,retaining 2～3 plants per 667m2.
