植物饼渣液体有机肥生产关键技术研究进展

Key Production Technology of Liquid Organic Fertilizer from Vegetable Oil Residue:Research Progress

以植物饼渣为主要原料,运用生物技术和物理化学方法相应设计了生产液体有机肥完整的工艺流程。笔者主要介绍了目标营养元素的确定、水解条件的优化、蛋白酶产生菌种的培育以及大量营养元素强化等技术,针对各种控制方法,阐述了其原理、应用条件及研究进展情况,提出了低成本规模化制作植物液体有机肥的新思路,为有机肥料的资源化利用提供了参考。

Based on vegetable oil residue, the whole process of producing liquid organic fertilizer was designedby using biotechnology and physical-chemistry method. The research mainly introduced some technologies,including the determination of the target nutrient elements, the optimization of the hydrolysis conditions, thecultivation of the protease strains and the enhancement of the nutrient elements etc. The paper also expoundedthe principles, application conditions and research progress of the control methods, and proposed a new waywhich was low-cost for large-scale production of liquid organic fertilizer. The results can provide references forthe resource utilization of organic manure.
