摘　　要：采用田间和盆栽试验,对越桔生长的土壤条件进行改良,通过调整土壤pH值、生长量及相关生理指标的对比分析研究,从而获得适合越桔生长的土壤类型。研究结果表明:在酸度适宜的范围内(pH值为4.0～5.0),苔藓或草炭加原土加硫磺粉的土壤改良类型适合越桔的生长,植株的高度、粗度、基生枝数都有明显的增加,尤其是原土加硫磺粉的土壤改良类型表现出明显优势,而且具有很大的潜在优势,说明在同样施足有机肥的基础上,只加硫磺粉调酸,越桔也能正常生长。Black soil was amended and 3 blueberry cultivars were cultured in pot and field. The suitable soil type will be obtained by changing soil pH, blueberry growth and some physiological-biochenical characters. The result showed that the amendment type of using moss or peat is fit for the growth of blurber-ry.The plant height,shoot length,dry weight of 100 leaves and leaf area increased with the decrease of soil pH. Especially the use of sulphur only showed a great superiority.
