魔芋家栽,大多采用块茎整芋直播,用种量大,繁殖系数低,成本高。加之块茎切块和顶芽带蒂直播,烂种率高,成苗率低。因而很不适应目前大面积商品生产的需要。为此,笔者近年开展了魔芋种子育苗试验,初获成功,现报道于后,以供参考。　　　　一、试验材料与方法　　　　供试种为普通 Konjac home planted, mostly used tuber of whole line live, with a large amount of breeding coefficient of low, high cost. In addition, tuber cutting and top bud pedicle live, rotten rate is high, the rate of seedling is low. It is not suited to the current needs of large-scale production of goods. To this end, the author carried out in recent years konjac seedling nursery test, initially successful, are reported later, for reference. First, the test materials and methods for the test species for the ordinary
