| 摘 要： | 在普通生产田和林间生产田,从品种、栽植密度和施用钾肥3方面研究了鲜食甘薯栽培技术.结果表明,所用3个甘薯品种(宁薯192、宁紫1号和济薯18)的商品薯产量构成差异较大,宁薯192为薯重型,商品薯比例高;宁紫1号为薯数型,小薯数量多;济薯18为中间型,商品薯产量较高.在普通生产田,栽植密度1 hm2 48 000株、增施225 kg/hm2硫酸钾,可获得最高的商品薯产量.在已成大树的林间生产田,鲜食甘薯的商品薯产量非常低.

| Abstract: | Cultivation practices on fresh sweetpotato were conducted on both farmland and interplanting poplars field with three factors of cultivar,planting density and potassium fertilizer.It was different in composition of marketable root yield among three cultivars.Ningshu 192 was a kind of root-weight type cultivar which gave high ratio of marketable root yield.Ningzi 1 was a kind of root-number type cultivar which gave lots of small root.Jishu 18 was the intermediate which gave higher ratio of marketable root nu... |
