| 摘 要： | 通过对5个不同处理的钾肥施肥量和3种不同栽培模式的研究,探讨在高海拔的干旱半干旱地区增施钾肥的必要性和适合马铃薯种植的最佳栽培模式。研究结果表明,增施钾肥后能够促进马铃薯的生长发育,产量和商品薯率都有所增加,说明在高海拔的干旱半干旱地区增施钾肥是有必要的。同时通过不同栽培模式的研究说明,起垄覆膜处理增温效果明显,有利于干旱半干旱地区马铃薯提前出苗,促进生长,缩短生育期,提高产量和商品率。

| Abstract: | Five different rates of potassium fertilizer application and three modes of cultural practice were tested in order to understand if the potassium is needed and what is the optimum cultivation mode for the potato production in the arid and semiarid region at high elevation.Potassium fertilization promoted the growth and development of potato and therefore increased the tuber yield and marketable tuber percentage,indicating that it is necessary to apply potassium fertilizer in potato production in the arid an... |
