平衡施肥油茶林土壤酶活性研究

he changes of soil enzyme activities were studied on Camellia forest with Different Fertilizer Application at Xinyu in Jiangxi The results showed that :The soil enzyme activities in balance fertilization forests were better than CK. For instance, the activities of soil invertase, protease, urease and catalase raise respectively 16.34%~72.04%, 4.40%~63.74%, 13.25%~172.29% and 8.52%~19.89%. Soil enzyme activities reduced gradually from top to bottom layer of soil profile in balance fertilization oil-tea forests. They reached to significant anode relevance between invertase, protease, urease and catalase. They reached prominent level or best prominent level, these showed that they had consanguineous relationship, the presence of soil enzymes was not alone, and they influenced jointly development of soil fertilities.
