摘　　要：本文研究不同垦殖年限红壤荔枝园土壤化学性状、酶活性及其两者的相关性。结果表明,闽南漳州地区荔枝园土壤养分含量及酶活性基本上随着垦殖年限的延长而升高,且在成年果园仍保持较高水平;土壤养分含量与酶活性具有一定相关性;土壤酶活性指标可供评价红壤荔枝园土壤熟化水平。作者提出了衡量荔枝园土壤良好熟化水平的养分含量及酶活性指标。The present investigation was carried out in Longhai, Nanjing county and Zhangzhou City of the South Fujian, in order to explore the changes both in chemical and enzymatic properties of litchi orchard soils, which have different lengthes of cultivation period, to find out the. correlation between them. It was found that most nutrient contents and enzyme activities increased with the extension of the cultivation duration, and higher fertility level in most litchi orchard soils of full fruit period has been maintained. There are significant or more significant correlations between several enzyme activities and some nutrient contents in this statistical analyse. Study shows that the enzyme activity is one of the important indexes for evaluating the mellowness degress of red soils in litchi orchards. And the indexes of the suitable mellowness level are suggested in this work. The present paper points out that the management practice of combining organic and mineral fertilizer application should be beneficial and important for the improvement of red soil fertility in litchi orchards.
