不同原材料园林废弃物堆肥产物肥效初探
A Preliminary Study on the Fertilizer Efficiency of Composting Products from Garden Waste of Different Raw Materials

为研究不同原材料园林废弃物堆肥产物的肥效，设置了枯叶(T1)、萝卜叶(T2)、萝卜叶 + 枯叶(T3)、紫草(T4)、紫草 + 枯叶(T5)、荨麻(T6)、荨麻 + 枯叶(T7) 7个不同处理进行堆肥处理，用其产物与原土混合作为三色堇盆栽基质，测定堆肥产物的养分含量及三色堇的发芽、开花等相关指标。结果表明，从养分角度看，以萝卜叶为原料的堆肥产物全氮(10.2 g/kg)、全磷(5.7 g/kg)、全钾(12.7 g/kg)等含量显著高于其它处理，而含有紫草的堆肥产物全氮(3.7 g/kg)、全磷(1.1 g/kg)、全钾(6.2 g/kg)等含量最低。从三色堇生长发育上看，萝卜叶堆肥产物混合原土种植的三色堇发芽率、开花数量及株高冠幅均最低。
In order to study the fertilizer efficiency of garden waste composting products of different raw materials, seven different treatments were set up for composting treatment, including dead leaves (T1), radish leaves (T2), radish leaves + dead leaves (T3), comfrey (T4), comfrey + dead leaves (T5), nettle (T6) and nettle + dead leaves (T7), and the products were mixed with the original soil as the potted substrate of pansy, and the nutrient content of the compost products and the germination and flowering of pansies were measured. The results showed that from the nutrient point of view, the contents of total nitrogen (10.2 g/kg), total phosphorus (5.7 g/kg) and total potassium (12.7 g/kg) in the compost products made from radish leaves were significantly higher than those in other treatments, while the contents of total nitrogen (3.7 g/kg), total phosphorus (1.1 g/kg) and total potassium (6.2 g/kg) were the lowest in compost products containing comfrey leaves. From the perspective of pansy growth and development, the germination rate, number of flowering and plant height and crown width of pansy planted with radish leaf compost products mixed with original soil were the lowest.
