| 摘 要： | 本文分析了中国尤其是云南省马铃薯种植中钾肥不足的原因,并介绍了价格低廉且含钾量较高的氯化钾在马铃薯种植中的应用方面的研究。依据美国等国在马铃薯种植中普遍应用氯化钾的情况及国内外目前的相关研究,提出应加强这方面的研究,以确定能否在中国的马铃薯种植中广泛施用氯化钾,从而达到改变目前马铃薯的种植中钾肥用量偏少这一现状的目的。

| Abstract: | Since potassium chloride was considered as poison to potatoes,potassium sulphate has been mainly used in potato productions in China.No chemical potassium fertilizer is used in most areas for potato production,because potatoes are mainly planted in poverty area in China,and this leads to low potato yield in China compared with the United State of America,where the potassium chloride is mainly used in potato production.The potassium chloride,a cheaper potassium fertilizer,should be used in potato growing aft... |
