为提升保障莲藕供给能力，节本增效，开展莲藕顶芽繁殖和整藕繁殖对产量和效益影响的对比试验。试验结果表明，自莲藕顶芽下1 cm处切下，经杀菌消毒后，移至育苗床，3周后移栽大田，通过施用有机肥和精细田间管理，其效益明显高于整身种藕常规栽培，可大幅降低种子成本，且主藕顶芽繁殖比子藕顶芽繁殖产量更高，具有较大的推广价值。% In the paper, we studied the effects of the apical bud propagation and conventional lotus root propagation on yield and benefit of lotus root production. We cut the apical buds of lotus root 1 cm under the buds, and moved the buds to the seedling bed after sterilization and disinfection, and then transplanted the seedlings to field three weeks later. The results showed that, the yield and benefit of the apical bud propagation were obviously higher than those of the conventional lotus root propagation by applying organic fertilizers and strengthening field management, and the apical bud propagation method sharply reduced the seed cost of farmers. In addition, the propagation technology using apical buds of mother lotus root possessed higher yield than that of lateral lotus root, and the propagation technology was more worthy of wide promotion.
