摘要: 通过大田试验,探讨施用麸酸有机复混肥与化肥配施对黄瓜产质量、土壤游离氨基酸、土壤微生物量碳等的影响。结果表明,麸酸有机复混肥与化肥配施能提高作物产质量、土壤有机质、速效氮磷钾、土壤游离氨基酸及土壤微生物量碳的含量。与单施化肥相比,黄瓜产量提高2.5%~7.9%,Vc提高4.9%~19.6%,可溶性糖提高6.7%~25.5%;硝酸盐降低0.4%~12.8%,土壤微生物量碳含量提高了26.7%~59.5%,且土壤微生物量碳含量与麸酸有机复混肥料氮施用量可用一元二次方程拟合,土壤中R基极性游离氨基酸含量占游离氨基酸含量比例有上升趋势。

Abstract: Field experiments were conducted to study the effect of Monosodium Glutamate Organic Compound Fertilizer on planting cucumber.The yield and quality of cucumber and the content of free amino acid and microbe-carbon in soil were analyzed.Results showed that the mix application of chemicals and monosodium glutamate organic fertilizers increased the cucumber yield and improved the soil quality in available N、P、K,free amino acid and biologic-carbon.Compared with chemical fertilizer,mixed compound fertilizers increased the cucumber yield about 2.5%-7.9% and improved its qualities in the contents of Vc,soluble sugar and biologic-carbon for about 4.9%-19.6%,6.7%-25.5% and 26.7%-59.5%,respectively.Concomitantly,the nitrate content of the cucumber was decreased for 0.4%-12.8%.Total carbon content of microbial biomass correlated to the organic nitrogen applied to soil with monosodium glutamate fertilizer was fitted well with one dimensional linear equation.

Key words: monosodium glutamate, cucumber, yield, quality, biologic-carbon in soil microbes, free amino acid
