利用沼肥生产无公害黄瓜综合栽培技术研究与应用

摘要

为了弄清施用沼肥对黄瓜生长发育和产量及品质的影响,为生产提供有效的配套栽培技术,进行了喷施不同浓度沼液、土施不同用量沼渣在黄瓜上的作用研究.结果表明,土施10.5 t/hm2的沼液为最佳施用量,叶面喷施60％的浓度为最适浓度；沼肥能显著促进黄瓜的营养生长和生物产量,有效提高黄瓜营养品质,可用于无公害黄瓜生产的肥料施用.%To understand effect of biogas dregs application to cucumber's growth, yield and quality, and to provide technology system for production, research about biogas dregs leaf-spraying and soil-application was conducted. The results showed that soil application of 10 500 kg/hm2 was the optimum dosage and leaf-spray of 60% concentration the most suitable level. Biogas dregs could significantly promote nutrition growth and biomass and effectively improve cucumber nutritive quality in pollution free cucumber production.
