| 摘 要： | 测定了不同垦殖年限红壤椪柑园土壤pH值和养分含量。结果表明,不同垦殖年限的红壤椪柑园土壤pH值差异不显著,且与土壤养分含量无规律性相关。由此可看出,在常规管理条件下,pH值与红壤椪柑园土壤熟化度的演化是不同步的。综合多年调查研究,作者认为,与水培试验不同,大田栽培的柑桔在土壤pH值较低的条件下仍可获得丰产。

| Abstract: | At both Tianma and Menghu citrus farms, Yongchun County, Fujian Province, pH values and some nutrient contents of red soils growing Ponkan at different periods were determined. The data showed that pH values were not significantly different (P>0. 05) among the all treatments. No regularly significant relationships were found between nutrient contents and pH values in most treatments. The pH values did not increase with the amelioration process of orchard red soil. It was pointed out that, unlike hydroponics experiments, the citrus production on the red soil orchards benefited by lower pH values because of the characteristics of having VA mycorrhizae. |
