摘　　要：为探究不同种植制度与种植密度对菊芋产量的影响,设置垄作(A1)和平作(A2)2种种植制度,60 cm(B1)、80 cm(B2)、100 cm(B3)3种行距进行大田试验,对收获期的地上茎叶生物量、地下块茎产量以及单个块茎质量进行分析研究。结果表明,垄作菊芋的地上茎叶生物量、地下块茎产量及块茎大小等指标均优于平作;从牲畜饲料收获和块茎产量角度,最优组合为A1B1;从块茎商品性和块茎产量角度,最优组合应为A1B3。因此,在推广菊芋种植制度时,可根据种植目的选择合适的栽培方式。本研究结果可为盐碱地菊芋高产栽培和资源高效利用提供理论指导。In order to investigate the effects of different cropping systems and planting densities on the yield of Helianthus tuberosus,two cropping systems were designed:ridge planting(A1)and flat planting(A2),and three row spacing experiments were carried out:60 cm(B1),80 cm(B2)and 100 cm(B3).The biomass of stem and leaf,the total tuber yield,and the individual tuber weight were analyzed.The results showed that the aboveground biomass,tuber yield and tuber size of H.tuberosus under ridge planting were higher than those under flat planting.From the perspective of feed collection and tuber yield,the optimal combination is A1B1.From the perspective of tuber marketability and tuber yield,the optimal combination is A1B3.Therefore,to promote H.tuberosus cropping system,suitable cultivation method can be selected according to the planting purpose.The results of this study can provide theoretical guidance for high-yield cultivation and efficient resource utilization of H.tuberosus in saline-alkali land.
