摘要: 选取3种单一类型园林废弃物(枯枝类、落叶类、草屑类)为试验材料,添加不同比例的豆渣和羊粪,通过高度集约化发酵设备进行制肥,在制肥过程的前期(初始混合期)、中期(设备发酵后)、末期(完全腐熟后)3个时间阶段进行取样,检测了有机质、pH、养分含量、发芽指数等指标。结果表明,草屑类按照豆渣∶羊粪∶园林废弃物1∶1∶8和1∶2∶7的2种处理表现最好,堆肥时间最短,总养分含量较高,pH适中,发芽指数较高,有利于植物生长,堆肥效果好,其中,草屑类按照豆渣∶羊粪∶园林废弃物1∶1∶8更具有经济优势。

Abstract: Three kinds of single types of garden wastes (litters, deciduous and grass debris) were selected as experimental materials, and different proportions of soybean residue and sheep manure were added. Fertilization was carried out by highly intensive fermentation equipment. Samples were taken at the early stage ( initial mixing stage), middle stage (after equipment fermentation), and late stage (after complete maturity) of the fertilization process. Organic matter, pH, nutrient content and germination index were detected. The results showed that the treatment of soybean dregs∶sheep manure∶green waste 1∶1∶8 and 1∶2∶7 had the best performance. Because of the shortest composting time, high total nutrient content, moderate pH and high germination index, they were conducive to plant growth and good composting effect. Among them, the treatment of soybean dregs∶sheep manure∶green waste 1∶1∶8 had more economic advantages.

Key words: garden wastes, resource utilization, fertilizer fermentation, germination index
