一串红是我国公共场所节日装饰的主要花卉．以生产上常用的腐叶土、红壤和砂配制盆栽用培养土，探讨其组成成分及其比例对土壤物理性质和一串红生长的影响．研究结果表明，以腐叶±２０％＋红壤５０％＋砂３０％的搭配比例组成的培养土，与对照相比较，具有较强的保水能力，持水量为２７．８９％，通气度接近５０％，通气透水良好，一串红生长旺盛，开花较多．生物量测定结果也表明花朵干重及全株干重均较高，是生产上一种经济方便，具有较高生产力的培养土．
A bunch of red is the main flower of our country public holiday decoration. The potted culture soil was made from the commonly used humus, red soil and sand in the production, and the effects of its composition and proportion on the physical properties of the soil and the red sage growth were discussed. The results showed that compared with the control, cultivated soil composed of ± 20% leaf + 50% red soil and 30% sand mixed with water had a strong water holding capacity of 27.89% and air permeability close to 50 %, Ventilation well, a bunch of red growth, more flowering. The results of biomass measurement also showed that the dry weight of the flowers and the whole plant dry weight were higher, which is a kind of culture soil with higher economic productivity and higher productivity.
