摘　　要：为探明深汕特别合作区水稻田土壤肥力质量状况,为水稻施肥管理、绿色健康发展提供科学依据,对水稻种植区进行土壤调查及取样分析。结果显示,土壤pH大部分处于4.5~5.5,最适宜的土壤仅占9.38%;有机质含量大部分处于中等偏上水平,但仍有28.12%的土壤有机质含量处于缺乏以下水平;土壤硝态氮、铵态氮和速效钾总体含量较低;土壤速效磷、有效铁含量丰富,有效铜、锌含量整体中等偏上;有效锰含量总体中等偏低,有46.87%的土壤为锰缺乏状况。建议结合水稻生长需求及土壤养分特征平衡施肥,对酸性或强酸性的水稻田适量施用矿物质土壤调理剂、有机肥、石灰氮及石灰以有效改善土壤酸化,为土壤质量提升和粮食安全生产提供保障。In order to study paddy field soil fertility quality in Shenshan Special Cooperation Zone,further provide scientific basis for rice ferti⁃lization management and green agricultural production,soil investigation and sampling analysis have been done in paddy field.The results showed that most of the soil pH values were between 4.5 and 5.5,and the soil samples with the most suitable pH only accounted for 9.38%.Or⁃ganic matter content of most soil samples was above medium level,but 28.12%of them was below lacking level.The contents of nitrate nitro⁃gen,ammonium nitrogen and available potassium were relatively low.The contents of available phosphorus and available iron were rich,and the contents of available copper and available zinc were at medium to high level.Available manganese content was generally at medium to low level,with 46.87%of the soil samples were in shortage or drastic shortage.In order to provide guarantee for soil quality improvement and rice safety production,balanced fertilization was suggested according to rice growth requirement and nutrient characteristics of paddy soils.Mean⁃while,in order to improve soil acidification,mineral soil conditioner,organic fertilizer,lime nitrogen and lime was suggested to apply appropri⁃ately in acidic and strongly acidic paddy fields.
