摘　　要：以微生物发酵有机肥为试材,以黄土高原温室栽培黄瓜为对象,研究了施用微生物发酵肥对温室黄瓜产量、经济效益以及品质的影响。结果表明:发酵肥与常规施肥相比对黄瓜产量无显著性差异,但经济效益比常规施肥相对高68.07%。在改善果实的营养品质与风味方面,与常规施肥比较,发酵肥平均相对降低黄瓜硝酸盐含量48.71%,维生素C含量平均相对增加51.61%,游离氨基酸含量相对增加33.13%,可溶性糖含量相对增加13.61%。发酵肥效应非常突出,故在温室蔬菜生产中生物发酵有机肥完全可以代替化肥与有机肥,可作为一种新型肥料大力推广生产绿色蔬菜。Taking the fermentation fat as the experimental material, the yield, quality and economic effectiveness, which collected from the cucumber greenhouse of I.oess plateau were investigated after application of the fermentation fertilizer. The results showed that there was no significance on the yield after application of fermentation fertilizer and regular fertilizer but economic effectiveness was improved up to 68. 07 %corresponding ; as for the cucumber quality,fermentation fertilizer could decrease its nitrate up to 48. 71% corresponding,improve the content of VC, free amino acid and soluble sugar contents up to 51. 61%,33. 13% and 13. 61%, respectively. The analysis showed that the micro-fermentation of organic fertilizer could be capable of replacing chemical fertilizer as more scientific and economic method of fertilization for pollution-flee vegetables in agricultural production.
