摘要

1 049 soil samples (0 ~ 40 cm) of citrus orchard in YiChang were analyzed. The results showed that citrus orchard soils reflected severe acidification and were lack of organic matter, effective nitrogen. Available phosphorus and available potassium were uneven distributed, so poor and rich phosphorus, potassium soils all existed. 1 049 citrus orchard soil samples were short of boron, and zinc and iron deficiency displayed in part of soils.%　　对宜昌市主要柑橘园土壤(0～40 cm)采样1049个进行分析，结果表明：柑橘园土壤肥力为土壤酸化，有机质缺乏，碱解氮普遍偏低，有效磷、速效钾含量不均等，既有缺乏的土壤，又有富磷、富钾的土壤。微量元素中普遍缺硼，部分缺锌、缺铁。
