进行了12年的魔芋北移引种试验．结果表明：魔芋引种在陕西渭河流域，能够完成生育周期，产量和品质与原产地无显著差异；廉于引种在陕西榆林和辽宁盖县，能够生长，品质与原产地相近，产量略低于原产地。在引种区栽培魔芋的最佳参数是：渭河流域播种期4月下旬，陕西榆林毛乌素沙区和辽宁盖县播种期4月中旬；球茎种重35O～500g种植，种植密度50cm×50cm，荫蔽度50％～60％；采收期：渭河流域10月下旬，榆林毛乌素沙区和辽宁盖县10月上中旬。还进行了魔芋分芽繁殖、生长动态规律、产量与柄茎的相关性、立体栽培等试验研究。
12 years of konjac northward shift test. The results showed that the introduction of konjac was able to complete the reproductive cycle in the Weihe River basin of Shaanxi Province. The yield and quality of konjak did not differ significantly from that of the original place of origin. The introduction of konjac was able to grow in Yulin, Shaanxi and Gaixian, Liaoning, with similar quality and origin, Origin. The best parameters for cultivating konjac in the introduced area are: sowing time in Weihe River Basin in late April, Mauusu Sandy Area in Yulin, Shaanxi Province and mid-April in Gaixian County, Liaoning Province; planting bulbs of 35O ~ 500g, planting density of 50cm × 50cm, 50% ~ 60%; Harvest period: Weihe River Basin in late October, Muyu Sands in Yulin and Gaixian in Liaoning in mid-October. Also conducted konjac bud reproduction, the dynamic law of growth, the yield and stem stem correlation, three-dimensional cultivation and other experimental study.
