| 摘 要： | 彩色马铃薯具有重要的营养价值,但目前对其栽培技术的研究还比较少。本文采用L9(34)正交试验设计,研究了肥料(P/K)、密度对彩色马铃薯品种紫云1号产量的影响。研究结果表明:在重庆市河谷浅区,紫云1号整薯播种获得高产的最优施肥量,每公顷纯P2O5施用量为50 kg,KH2PO4喷施浓度为2‰,最合理密度每公顷为75 000株。

| Abstract: | Though color potato has important nutritive value,its cultivation technique still has seldom been studied until now.In this research,orthogonal experiment L9(34) was adopted to investigate the effect of fertilizer(P/K) and plant density on yield of the color potato variety Ziyun 1.The result indicated that high yield of the color potato could be reached in the shallow valley region of Chongqing when P2O5 was applied at the rate of 50 kg as basal fertilizer and KH2PO4 at the concentration of 2‰ as foliage fertilizer,and the potatoes were planted at 75000 hills per hectare. |
