摘要： 为了解厨余垃圾堆肥对土壤性状和植物生长的影响，以不同比例混合的原土和厨余垃圾堆肥作为盆栽基质栽培鸡冠花，检测基质性状和鸡冠花生长指标的变化。结果表明，添加厨余垃圾堆肥可以显著提高基质中有机质、全氮、速效磷等含量，堆肥含量从5%增加到100%，有机质含量从22.68 g/kg增加到317.71 g/kg，全氮含量从1.36 g/kg增加到14.9 g/kg，速效磷含量从33.18 mg/kg增加到228.25 mg/kg。垃圾堆肥及其混合基质中8种重金属含量均低于绿化有机基质的标准，其中仅有Cu含量因添加堆肥而升高，但在堆肥含量5%~80%之间，Cu含量与对照均差异不显著；在堆肥含量5%~20%基质中鸡冠花植株地上及地下生物量显著高于对照，其中10%含量的基质中鸡冠花生长最好，其地下干重为对照组的3.61倍。根据以上结果可得出如下结论：适量使用厨余垃圾堆肥可显著促进鸡冠花的生长；作为花卉栽培基质使用，推荐使用比例为5%~20%。

Abstract: In order to study the effect of domestic waste compost on the growth of Celosia cristata and soil property, a pot experiment was developed with Celosia cristata grown in substrates at different proportions of soil and domestic waste compost. The property of the mixed substrates and the growth index of Celosia cristata were measured. The results showed that the contents of organic matter, nitrogen and available phosphorus were significantly raised by adding domestic waste compost. When the compost content was from 5% to 100%, the content of organic matter was raised from 22.68 g/kg to 317.71 g/kg, nitrogen was from 1.36 g/kg to 14.9 g/kg and available phosphorus was from 33.18 mg/kg to 228.25 mg/kg. The detected 8 heavy metal contents in domestic waste compost were all less than the level of organic media standards for green use, among which only the content of Cu was raised by adding the compost, but there was no significant differences between the control soil and mixed substrates of compost content of 5%-80%. The shoot and roots biomass of Celosia cristata which grew in the substrates of 5%-20% domestic waste compost were significantly higher than that of the control; the plants grew in substrates of 10% domestic waste compost were the best，the root biomass was 3.61 times of the control. Then, it is concluded that the domestic waste compost can significantly improve growth status and quality of Celosia cristata, and be used as substrate for flower cultivation, and 5%-20% compost in soil could be acceptable.
