不同土壤肥力与施肥处理对黄瓜产量及经济效益的影响

通过田间试验,探讨了不同土壤肥力与施肥处理对黄瓜产量、效益的影响.结果表明：在不同土壤肥力条件下施用氮、磷、钾肥能最大限度提高黄瓜产量和纯收益;其中增产率和增收率最高的处理为中等肥力土壤条件下,施氮、磷、钾肥的处理,增产率达到73.75％,增收率达到65.65％.氮、磷、钾对黄瓜产量的影响程度为氮＞磷＞钾.因此,为提高黄瓜产量及效益必须高度重视科学施肥,改变农民重氮肥、轻磷、钾肥的施肥习惯,从而提高农民种植黄瓜的经济效益.

Effects of Different Soil Fertilities and Fertilizer Treatments on Yield and Benefit of Cucumber

The field experiment of cucumber was carried out to study the effects of different soil fertilities and fertilizer levels. The results showed that applying N, P and K could maximum increase yield and benefit of cucumber under different soil fertili- ties, the treatment of highest y~eld increasing rate and benefit increasing rate is applying N, P and K under the middle soil fer- tility condition, the yield increased 73. 75%, the benefit increased 65. 65%. N,P and K have the effect on cucumber yield under the testing condition and the effect trends was N〉P〉K. Therefore, we must pay more attention to scientific fertilization, in- creasing P and K application amount is beneficial to increase yield and benefit of cucumber.
