皂素头道废水肥料化技术及应用研究

Study on fertilizer technology and application of diosgenin head wastewater

以皂素头道废水为原料,采用现代生物技术得到一种满足猕猴桃生长需求的无机-有机叶面肥。大田实验表明,在猕猴桃膨大期时,每半个月喷施1次无机-有机叶面肥(1∶600),能显著提高猕猴桃产量和质量,延长猕猴桃的保质期。同等条件下,该叶面肥优于猕猴桃专用叶面肥“高美施”(1∶400)的喷施效果。该技术为高酸度、难降解有机废水肥料化利用提供借鉴。

A kind of inorganic-organic foliar fertilizer for kiwifruit was prepared by modern biotechnology using diosgenin head wastewater as raw material.It was found that spraying inorganic-organic foliar fertilizer(1∶600)every half-month during the swelling period of kiwifruit could significantly improve the yield and quality of kiwifruit and prolong its shelf life by field experiments.Under the same conditions,the effect of the foliar fertilizer was better than that of the special foliar fertilizer for kiwifruit“Gao mei shi”(1∶400).The technology can be used as a reference for fertilizer utilization of high acidity and refractory organic wastewater.
