摘要
对贵州南亚热带、中亚热带地区3个杂柑果园0～30cm土层的pH值、有机质、碱解氮、有效硼、速效磷、速效钾、有效锌等营养成分进行了检测分析。结果表明:3个果园除土壤有机质及pH值较适宜外,试验点土壤缺素现象较为严重。土壤综合条件较好的罗甸试点,其杂柑品种的长势较好,其次为天柱,榕江最差。说明,土壤营养成分的高低是影响柑橘生长、产量和品质的主要因素。
The pH value and contents of organic matter, alkaline hydrolysis N, effective B, active P, active K and effective Zn in the soil layer with 0 to 30 cm of 3 citrus orchards from South and Middle subtropical areas were determinated. The results indicated that the soil from 3 orchards seriously lacks nutrients besides suitable pH value and organic matter, and the soil comprehensive condition order of 3 tested orchard is Luodian orchard, Tianzhu orchard and Rongjiang orchard. The main factor affecting citrus growth, yield and quality is soil nutrient contents.
