摘要
为了探究适宜园林绿化植物生长的湿垃圾堆肥产品(简称“湿垃圾”)添加量,选取伞房决明、大花秋葵、皇帝菊3种园林绿化植物为研究对象,在分析测定湿垃圾不同添加量对3种园林植物株高、蓬径、叶绿素含量、叶面积、生物量等影响的基础上,采用主成分分析法对3种植物的生长状况进行了综合评价。结果表明:湿垃圾不同添加量对伞房决明、大花秋葵、皇帝菊在不同生长时期的株高、蓬径、叶绿素含量、叶面积、生物量等影响不同。但就植物整个生长期而言,湿垃圾添加量为10%—20%时对3种植物均有较显著促进作用。其中,添加10%湿垃圾的处理下伞房决明和皇帝菊长势最佳,添加20%湿垃圾的处理下大花秋葵长势最佳。该研究不仅为湿垃圾资源化利用提供了出路,而且为湿垃圾堆肥产品合理利用于园林绿化提供了理论依据。
In order to explore the amount of food garbage compost products suitable for the growth of different landscape plants,three garden plants,including Cassia corymbosa,Hibiscus grandiflorus and Melampodium divaricatum,were selected as research objects in this study.Based on the analysis and determination of the effects of different amount of food garbage compost products on plant height,canopy diameter,chlorophyll content,leaf area and biomass of three garden plants,principal component analysis method was used for comprehensively evaluating the growth status of three kinds of gardening plants.The results showed that different amount of food garbage had different effects on plant height,canopy diameter,chlorophyll content,leaf area and biomass of Cassia corymbosa,Hibiscus grandiflorus and Melampodium divaricatum in different growth stages.However,for the whole growth period of plants,when the amount of food garbage was 10%—20%,all of them had a significant promoting effect on the three plants.Among them,Cassia corymbosa and Melampodium divaricatum grew best when they added 10%food garbage compost products,and Hibiscus grandiflorus grew best when they added 20%food garbage compost products.This study not only provides a way out for the utilization of food garbage resources,but also provides a theoretical basis for the rational use of food garbage compost products in landscape greening.
