| 摘 要： | 以津优1号黄瓜为试验材料,研究了硫酸钾施用水平对黄瓜矿质元素含量的影响。结果表明,适量增施钾肥可以显著促进黄瓜对钾的吸收,而对N、P、Mg、Ca的吸收没有显著影响;在施K2O 0～900kg/hm2时,可以促进黄瓜对微量元素Mn、Zn的吸收,降低对Cu的吸收;而当K2O超过900 kg/hm2时,Mn、Zn、Cu三种微量元素的吸收均有降低趋势。

| Abstract: | The effect of potassium fertilizer on mineral uptake of cucumber in solar-greenhouse was studied.The cultivar Jinyou1 was planted with different potassium levels.The results showed that potassium fertilizer increased the content of potassium in cucumber and had no effect on the content of N,P,Mg and Ca.When 0～900 kg/hm2 K2O were applied,the contents of Mn and Zn increased,but the content of Cu reduced.When more K2O(>900 kg/hm2) was applied,the contents of Mn,Zn and Cu were all reduced. |
