Study on four fertility indexes of soil in road greening belt of Guiwan area in Shenzhen City

本文对深圳市桂湾片区面积约67.8万m2的绿化种植用地进行了肥力调查研究,调查数据表明:前湾片区道路绿化带是属于盐碱地,pH值6.19~8.91;肥力4大指标中的有机质、有效磷、水解性氮均未达到《绿化种植土壤(CJ/T340-2011)》标准,建议对该片区的绿化带种植区肥力进行改善。

This paper conducts a fertility investigation on the greening planting area of about 678,000 square meters in the Guiwan area of Shenzhen.The survey data show that the road green belt in Qianwan area belongs to saline-alkali land,with pH value of 6.19~8.91;The organic matter,available phosphorus and hydrolyzable nitrogen did not reach the“Green Planting Soil(CJ/T340-2011)”standard,and it is recommended to improve the fertility of the green belt planting area of the area.
