摘要

[目的]研究赣南中低产田区双季稻机插适宜播种量。[方法]早晚稻各设置5个不同播种量处理，并以常规抛秧处理为对照，探讨赣南中低产区双季稻机插的适宜播种量。[结果]该区机插早稻播种量70g/盘（360盘/hm2）、晚稻播种量60 g/盘（360盘/hm2）时产量最高。机插早稻产量与有效穗数、每穗粒数显著正相关，机插晚稻与有效穗数显著正相关，保证足够的有效穗数是提高该区机插稻产量的重要措施。[结论]该区双季稻机插存在适宜播种量，且产量较高。%Objective] The aim was to research the appropriate seeding quantities of double-season machine-transplanted rice in middle and low-yielding district of south-ern Jiangxi Province. [Method] The research set five different seeding quantities treatments, and compared with conventional seedling treatment, and the appropriate seeding quantities of double season machine-transplanted rice in middle and low-yielding district of southern Jiangxi Province was discussed. [Result] The yields were highest when the seeding quantity was 70 g per tray of early rice by mechanical transplanting and 60 g per tray of late rice. The yield of early rice by mechanical transplanting showed significantly positive correlation with the number of productive ear and the number of seed per ear, and late rice yield showed significant correla-tion with the number of productive ear by mechanical transplanting. It is key for im-proving high yields by guaranteeing the number of productive ear. [Conclusion] The issue of proper sowing quantity should be taken into consideration for double-crop-ping rice in the region, which is crucial for high yields.
