| 摘 要： | 采用鸟巢蕨盆栽试验，研究组配改良剂（竹酢液+麦饭石）施用对园林废弃物堆肥栽培基质理化性质和植株生长的影响。结果表明，组配改良剂的施加对栽培基质容重、总孔隙度、持水空隙和通气孔隙等物理性质影响不明显；组配改良剂的施加对化学性质有显著影响，降低有机碳含量和基质pH值，提高基质EC值及全氮、全磷、全钾、碱解N、速效P、速效K的含量，同时对微量元素Cu、Zu、Fe含量提高有积极作用；组配改良剂添加促进了植株生长，提高了生物量的积累（鲜质量）、株高、冠幅，叶绿素含量，同时提高植株全N、全P、全K营养元素含量。将栽培后基质和植株之间各指标进行综合比较，组配改良剂稀释1 000倍竹酢液500 mL/kg+麦饭石40 g/kg，效果最佳。

| Abstract: | The aim of this research was to evaluate the effects of combined amendments (bamboo vinegar + medical stone) on physicochemical properties of green waste compost substrates and growth and nutrition of Asplenium nidus. The results showed that the application of combined amendments had no significant effects on bulk density, total pore space, water hold capacity and air space value of the growing substrates. The utilization of combined amendments resulted in the decreases of organic matter content and pH of the growing substrates compared to the control. On the other hand, the application of combined amendments resulted in the increases of EC, contents of total nutrients (tatol N, P, K), available nutrients (available N, P, K) and micronutrients (Fe, Zn, and Cu) of the growing substrates. Combined application of bamboo vinegar and medical stone promoted plant growth, and also increased chlorophyll, N, P, K contents of the plants, which accordingly had the plant weight, plant height and leaf surface increased. The combined amendments of applying 500 mL/kg 1 000 times dilution bamboo vinegar + 40 g/kg medical tone to the green waste compost substrates had the best effect. |
