【摘要】 在设施条件下,研究了不同钾肥用量对黄瓜生长性状的影响.结果表明,在氮、磷肥适量施用的基础上,随着施钾肥量的增加,黄瓜还原糖和Vc含量及产量增加.通过对不同处理间的差异分析,结果表明,当施钾肥720kg·hm-2时,肥料增产效益最佳.更多还原

【Abstract】 A preliminary study was conducted on the effect of different application amount of potassium fertilizer on the growth character of cucumber under the equipment condition.The results indicate that,with the increase of the application amount of potassium fertilizer,the reluctant sugar,the Vc content,and the yield of the cucumber rise on the basis of the appropriate application amount of nitrogen and phosphorus.Result of analysis of the difference among the different treatment indicates that the yield_increasing benefit of the potassium fertilizer is the best when 720 kg·hm^-2 is applied.更多还原
