保护地条件下黄瓜对养分的吸收量是K＞N＞Ca＞Mg＞P。养分最大吸收量出现在盛瓜期。各种矿质元素在不同器官的分配有所不同，根为K＞N＞Ca＞P＞Mg，茎为K＞Ca＞N＞Mg＞P，叶为Ca＞N＞K＞Mg＞P，瓜为K＞N＞Ca＞Mg＞P。氮钾合理配合能提高黄瓜产量、光合作用、品质及抗病能力。
Protected cucumber nutrient absorption under the conditions of K> N> Ca> Mg> P. The maximum absorption of nutrients appeared in the melon period. The distribution of various mineral elements in different organs was different, with K> N> Ca> P> Mg, K> Ca> N> Mg> P and Ca> N> K> Mg> K> N> Ca> Mg> P. Rational combination of nitrogen and potassium can improve cucumber yield, photosynthesis, quality and disease resistance.
