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。
Cucumber as a test material to study the different concentrations of N on cucumber growth and yield, yield and quality, to determine the best local optimum nutrient solution formula, and on this basis, different nutritional value of nutrient solution EC cucumber growth, yield and quality Impact. The results showed that (-20% N) had the best correlation with cucumber growth, the average yield and quality of cucumber were higher than (+ 20% N) and control treatment, Set up four different concentration gradients (% EC) in the% N recipe. EC 3.5mS / cm has the highest yield and best quality and is the best nutrient solution.
