针对上海绿化土壤普遍存在结构差、肥力偏低、植物长势不佳等现状，以绿化植物废弃物（树枝）、牛粪和土壤不同比例进行了金盏菊和孔雀草2种植物的盆栽试验。结果表明：金盏菊和孔雀草的生长主要受2个成分影响，第1个主要是EC、全氮和有效磷，占48．6％，第2个成分为pH值，占22．9％。添加牛粪可以增加土壤全氮和有效磷的含量，但其添加比例应小于50％（体积比）；添加绿化植物废弃物可以改善土壤结构，但存在养分缺乏的缺点，应与土壤或牛粪混合使用；就配方而言，绿化植物废弃物：牛粪：土壤的比例分别以7：0：3、5：3：2、6：4：0的处理效果较好。

According to the conditions of poor greening planting soil which included bad structure, low fertility and bad growth in shanghai, this paper conducted a research on different ratio of greenery waste, cow dung and soil with Calendula officinalis and French Marigold potting experiments. The results showed that there were two principal components (PC1 and PC2)were identified, Factor 1, which explained 48.6% of the total variance, including EC ,TN and TP.Factor 2 ,pH explained 22.9% of the total variance. The addition of cow dung could improve soil content of TN and TP ,but application amount (volume ratio)should be less than 50%. Addition of greenery waste could improve soil structure condition,and it should be used with cow dung to improve fertility.The best growth of the plants were the treatments whose ratio of greenery waste:cow dung:soil was 7:0:3,5:3:2,6:4:0,respectively.
