Abstract

Abstract: In order to study the effect of machinery compaction on urban green land soil and provide reference for urban vegetation plantation and scientific management of soil, soil physical and chemical properties and nutrient characteristics were studied and analyzed after machinery compaction in the new Xi’an botanical garden. The results showed that soil bulk density increased after machinery compaction, and porosity decreased, soil bulk density of 0-30, 30-60 and 60-100 cm increased by 4.20%, 14.60% and 20.70% in comparing with that before machinery compaction; soil pH value increased after machinery compaction; surface soil available nitrogen content increased by 287%, available phosphorus increased by 20.30%, available potassium increased by 12.10%, the change of organic matter content was not obvious. Soil structure was destroyed after machinery compaction, which caused the increase of soil bulk density and pH value, and changed nutrient distribution. Taking into account the above problems caused by machinery compaction and the complexity of botanical garden construction, accurate soil recovery measure and long-term observation of machinery compaction were necessary.
