摘　　要：选择常州典型茶园进行实地调查,分析了茶园土壤酸化现状及其发展趋势。结果表明,种植年限较长的常州茶园土壤呈现出不同程度的酸化、紧实、板结、缺磷、富氮等凸出问题。建议当地茶企要按照茶园土壤的酸化程度开展分段治理、土壤修复,比如应用“茶树修剪和调落物腐熟发酵还园”、“施用生物有机肥”、“施用生物质炭”、“施用绿肥”等措施。当地茶农应避免长期偏施化学氮肥习惯,做到科学合理施肥、测土配方施肥。Field investigations were conducted on typical tea gardens in Changzhou and the current status and development trends of soil acidification in tea gardens were analyzed.The results were showed that tea gardens with longer planting years exhibited prominent problems such as soil acidification,compaction,phosphorus deficiency,and nitrogen enrichment to varying degrees.It is recommended that local tea companies carry out segmented management and soil remediation according to the degree of soil acidification in tea gardens,including"the use of tea plant pruning material to field undergone suficient fermentation","biofertilizer application","biochar applicaiotn","green manureapplication",etc.Local teafarmersshould avoid the habit of long-term biased application of chemical nitrogen fertilizers,and achieve scientific and reasonable fertilization,soil testing and formula fertilization.
