摘要
在日光温室研究了黄瓜采收期4个不同氮、钾配比施肥处理对其植株生长、果实产量及品质的影响。结果表明,施肥处理的黄瓜其产量和品质明显高于不施肥对照,增施钾肥有利于黄瓜的产量提高,采收期追施肥的氮钾(N:K2O)比例以1:1.8的效果最好,表现为施肥后提高了光合速率,促进了黄瓜植株生长,显著提高了黄瓜产量,并使黄瓜的营养品质得到了明显改善。
In order to provide theoretical basis for rational fertilization cucumber,and for formulating scientific cultivation technique and management measures to provide the reference.This experiment was made to analyze the effects of the different NK ratio on growth,yield and quality of cucumber in the greenhouse.The results showed that cucumber of plant nutrition that influenced to grow and produce quality had significant,four processing effects were obviously superior to that of the control processing effect,the effect that potash to appropriately increase the cucumber surveyed vegetative growth and improve production quality.Which N：K 2 O proportion to 1：1.8 works the best,to promote the growth of cucumber plants,to improve the speed of photosynthesis,and the cucumber of the best quality,the highest yield.
