摘　　要：采用田间试验,研究施用不同量硅钙钾肥对陕北日光温室黄瓜生长与产量效果。结果表明:不同施用量硅钙钾肥能明显促进日光温室黄瓜株高生长和叶面积增加;黄瓜生长健壮,茎粗增加,黄瓜蔓长增加,促进黄瓜早开花,结果数量增多。在施用量25～100kg/667m2范围内,日光温室黄瓜产量增加104.3%～112.0%。施用硅钙钾肥是提高日光温室黄瓜产量的有效措施之一。Field experiment was carried out to investigate the effect of Si-Ca-K fertilizer on the growth and yield of cucumber in solar greenhouse in Northern Shaanxi. The results showed that different application amount of Si-Ca-K fertilizer could significantly promote the growth of cucumber stem, increase leaf area, stem diameter and vine length. Similarly, accelerate flowering of the inflorescence, increase the number of fruits. The yield of cucumber increased from 104. 3% to 112. 0% under the Si-Ca-K fertilizer 25-100 kg/667m2. The Si-Ca-K fertilizer was one of efficient measures to increase the yield of cucumber in solar greenhouse.
