摘要
在日光温室内,采用盆栽方式研究了不同氮磷钾养分配比对土壤栽培黄瓜产量及其品质的影响。结果表明:增加磷素用量和比例可以显著提高黄瓜的产量;适量氮钾肥配合增施磷肥可以增加果实中可溶性蛋白含量,适量氮磷肥配合增施钾肥可以改善果实品质,提高可溶性糖和维生素C含量,降低硝酸盐含量。
In order to investigate effects of N P K ratio on yield and quality in solar greenhouse cucumber (Cucumis sativas L), the experiment was carried. The results showed that ample phosphorus fertilizer development and improved cucumber's output significantly; Proper N, K and more P improved the soluble protein of fruit . Proper N-P fertilizer cooperated with more K fertilizer improved fruit quality, increased the content of soluble sugar and vitamin C,it also decreased the content of NO^-_3.
