摘 要：
在延迟播期的栽培条件下,研究播种密度对叶芥不同品种株高、开展度等农艺性状及产量性状的影响。结果表明,不同播种密度对紧凑型品种(A2)株高、开展度、单株质量的影响较小,对开展型品种(A1)产量、株高的影响小,但开展度和单株质量均显著下降;随着栽培密度的增加,叶芥产量增加,紧凑型品种(A2)在低密度区增产率比开展型品种(A1)低,但在高密度区增产率比开展型(A1)品种高。在延迟播期的情况下,紧凑型品种(A2)更适合通过提高种植密度获得高产。

摘 要：
Under the condition of delayed sowing date, the effects of sowing density on different agronomic traits(such as plant height, diameter and so on) and yield traits of two cultivars of leaf mustard were analyzed. The results showed that different sowing densities had little effect on plant height, degree of development and individual plant quality of compact cultivar(A2), besides had little effect on yield and plant height of expanded cultivar(A1), the degree of development, individual plant quality of expanded cultivar(A1) decreased significantly. The yield of different cultivars increased with the increase of planting density. Compact cultivar(A2) showed lower yield increase in low density area than expanded cultivar, and higher yield increase in high density area than developing cultivar. Compact cultivar(A2) was more suitable for high yield in high density planting with delayed sowing date.
