摘　　要：以黄瓜为试材,研究不同N素浓度对黄瓜生长发育、产量及品质的影响,确定适宜当地的最佳营养液配方,并在此基础上研究营养液不同EC值对黄瓜生长、产量及品质的影响。结果表明:在(-20%N)与黄瓜生长相关指标最好,黄瓜单株平均产量与品质高于(+20%N)处理、对照处理,可以作为最优N素配方;比较在-20%N配方下设置4个不同浓度梯度的处理(用电导率EC表示),EC 3.5mS/cm产量最高,品质最好,为最佳营养液配方。Taking cucumber as material.The growth,yield and quality of cucumber grown under the cultivation mode of Matrix-nutrient solution by changing the concentration of N in nutrient solution and the EC value of nutrient solution while the concentrations of the other nutrients remains unchanged.The results showed that parameters related to the growth of cucumber were the highest when the plants were grown at-20% N treatments,which were significantly higher than that of the plants grown at the other treatments,and the changes of yield per plant and quality of cucumber fruits follows the same trend.In the second stage of the research,four different concentration gradients of nutrient solution treatment were designed based on the results of the first stage of the experiment（expressed as EC,mS/cm）.Both of parameters related to the growth of cucumber plants and the quality of cucumber fruits were the highest for the pants grown at EC 3.5mS/cm.
