在秋季条件下以节瓜七星仔为材料，设置低氮低钾（N_(12)K_9）、低氮中钾（N_(12)K_(18)）、低氮高钾（N_(12)K_(36)）、高氮低钾（N_(18)K_9）、高氮中钾（N_(18)K_(18)）和高氮高钾（N_(18)K_(36)）等6个处理，研究了氮钾营养对节瓜生长、果实产量和品质的影响．结果表明，提高氮、钾水平，节瓜植株干重和果实产量都呈增加的趋势，增钾比增氮的效果更明显；果实的总糖和Vc含量有下降的趋势，还原糖含量无明显的规律性变化;果实的氮、磷和钾含量呈增加的趋势，但有个别处理例外．
Under the conditions of autumn, the low nitrogen and low potassium (N_ (12) K_9), low nitrogen and potassium (N_ (12) K_ (18)), low nitrogen and high potassium (N 36 K 18) and high nitrogen and potassium (N 18 K 30), high nitrogen and potassium (N 18 K 9), high nitrogen and potassium (N 18 K 18) and high nitrogen and potassium (N 18 K 36) The effects of nitrogen and potassium nutrition on the growth, yield and quality of fruit were studied. The results showed that increasing nitrogen and potassium levels, dry weight and fruit yield of Chieh-ching showed a trend of increasing, and the effect of increasing potassium was more obvious than that of increasing nitrogen. The total sugar and Vc content of fruit showed a declining trend while the content of reducing sugar had no obvious Of the regular changes; fruit nitrogen, phosphorus and potassium content showed an increasing trend, but with individual exceptions.
