针对随县澴潭镇油茶种植中土壤养分不均、油茶产量不稳等问题,研究其土壤养分和土壤肥力状况,为油茶土壤养分诊断及科学施肥提供依据.采集随县典型油茶园0～40 cm 土层样品,测定土壤pH值、有机质、全氮、速效磷、速效钾、有效硼及有效锰的含量,与全国第二次土壤普查分级标准进行比对评价,并对土壤pH值和养分含量进行相关性分析.结果表明:①土壤pH值总体上偏酸性.②土壤有机质含量中等,全氮含量较缺乏,速效磷、速效钾、有效硼含量极缺乏,有效锰含量非常充足.③土壤pH值与土壤有机质、全氮、速效磷、速效钾、和有效锰含量均呈显著正相关关系.综上所述,建议适当增施磷、钾肥及硼肥,并密切关注土壤pH值的动态变化.
Aiming at problems of unbalanced soil nutrients and unstable yield of Camellia oleifera in Sui County,the sta-tus of soil nutrients and soil fertility were studied and evaluated to provide the basis for scientific fertilization and soil nu-trient diagnosis.0～40 cm soil samples were collected to analyze soil pH and the contents of organic matter,total nitro-gen,available phosphorus,available potassium,available boron and available manganese.Soil fertility was compared and e-valuated with soil nutrient classification standard of the second national soil survey.Correlation analysis of pH soil nutri-ent content in C.Oleifera orchard was conducted.The results showed that:①Soil pH was slightly acidic.②The soil or-ganic matter content reached the intermediate level.The soil total nitrogen content was in the deficient level.The con-tents of available phosphorus,available potassium and available boron in soil were extremely low.The soil available man-ganese content was abundant.③Soil pH was significantly positively correlated with the content of organic matter,total ni-trogen,available phosphorus,available potassium,and available manganese in soil.In conclusion,phosphorus,potassium and boron feitilizer should be added appropriately and the variation characteristic of soil pH should be given close con-cern.
