通过对黄瓜进行不同氮磷钾肥料量级的田间试验,研究分析氮肥、磷肥、钾肥对黄瓜植株性状、产量、效益的影响,从而确定当地的氮、磷、钾肥的合理用量。结论:在当地土壤肥力较低的条件下,随着氮、磷、钾肥料的增加,黄瓜产量增加;氮肥、钾肥增加的趋势较磷肥明显;产量及经济效益最高的是处理5即施用氮肥30 kg、磷肥10 kg、钾肥12 kg,若施用45%的配方肥,配方较好地是26:8:11。
The effects of nitrogen fertilizer, phosphate fertilizer and potassium fertilizer on the plant characters, yield and benefits of cucumber were studied by field experiments on different nitrogen, phosphorus and potassium fertilizers in cucumber to determine the reasonable amount of nitrogen, phosphorus and potassium fertilizer. Conclusion: Under the condition of low local soil fertility, the yield of cucumber increased with the increase of nitrogen, phosphorus and potassium fertilizers; the trend of nitrogen and potassium fertilizer increased obviously compared with that of phosphate fertilizer; the highest yield and economic benefit were the application of nitrogen fertilizer 30 kg, phosphorus fertilizer 10 kg, potassium fertilizer 12 kg, if the application of 45% of the formula fertilizer, the formula is preferably 26: 8: 11.
