摘要
采用室内分析和野外调查相结合的方法,研究了宜宾市土壤容重和速效养分现状。结果表明,公园绿地、街头绿地、附属绿地土壤容重能满足植物生长需求,道路绿地土壤容重偏大,影响植物生长;速效氮和速效钾含量能满足植物需求而速效磷含量不足,需要补充。
Studies were made of the soil bulk density and available nutrient status in Yibin City by field investigation and indoor analysis. The results showed that the soil bulk density of park green space, green street, attached green space could meet the demand of plant growth, and yet the soil bulk density of the road affected the plant growth for its relatively big bulk density. The available nitrogen and available po- tassium could meet the demand of plant growth ,but the content of available phosphorus was low ,thus nee- ding supplements.
