摘　　要：为创新莲藕繁种技术,推动莲藕实生种子做种技术的应用,以莲藕纯系品种五月早为材料,对实生种子做种和种藕生产进行大田比较试验。结果表明,莲藕实生种子的纯度为97.5%,符合大田生产要求;生长前期,实生苗的株高、叶柄粗、立叶长半径和短半径、立叶数等均小于种藕;生长中后期,两种繁殖方式的株高、叶柄粗、立叶长半径和短半径差异均不显著,但实生苗的立叶数量显著多于种藕苗,生产的莲藕成熟时间比种藕苗晚21 d,整藕质量低于种藕苗,但单位面积内莲藕支数[813.7支·(667 m^(2))^(-1)]显著高于种藕苗[593.6支·(667 m^(2))^(-1)],而两种繁殖方式的莲藕产量差异不显著,且相比种藕,实生种子具有运输方便、损耗小、带病少等优势。In order to innovate the lotus seed reproduction technique and promote the application of lotus true seed technology,this paper took lotus pure line variety‘Wuyuezao’as material and conducted field comparative experiment between true seed and lotus rhizome seedlings production.The results showed that the purity of lotus true seed was 97.5%,which met the requirements of field production.During early growth stage,the plant height,petiole diameter,leaf long radius and short radius,number of standing leaves of true seed were smaller or less than those of rhizome seedlings.In the middle and late growth stages,the plant height,petiole diameter,leaf long radius and short radius of these 2 reproduction methods showed nonsignificant differences,while the number of standing leaves of true seedlings was significantly more than that of rhizome seedlings.The ripening time of lotus seedlings was 21 days later than that of rhizome seedlings.The whole lotus weight of true seed was lower than that of the rhizome seedlings,but the number of rhizomes per 667 m^(2)(813.7)was significantly higher than that of the rhizome seedlings(593.6).Lotus root yields of these 2 reproduction patterns showed not significant difference.Moreover,comparing with conventional rhizome seedlings,the true seeds had the advantages of convenient transportation,low loss and less disease.
