2006—2008年对襄阳区全区耕地土壤进行了拉网式采样测试分析,摸清了耕地土壤养分现状与变化规律,与1980年土壤普查结果相比土壤有机质基本持平,但水稻土、潮土有机质呈下降趋势,而黄棕壤有机质上升;各土类土壤全氮、碱解氮及全磷、速效磷含量均上升;土壤全钾、速效钾各土类均下降;pH值整体偏弱酸性。根据现状提出增施有机肥、分区合理施用化肥等施肥对策。 From 2006 to 2008, the cultivated soils in Xiangyang District were sampled and analyzed by pull-net sampling method to find out the status of soil nutrients and their variation in cultivated land. Compared with the results of the soil survey in 1980, the soil organic matter was basically the same, but the paddy soil, The content of total organic nitrogen and organic phosphorus in yellow brown soil increased; the contents of total nitrogen, total nitrogen and total phosphorus and available phosphorus increased in all soil types; the contents of total potassium and available potassium decreased; . According to the status quo put forward by adding organic fertilizer, fertilization and other fertilizers countermeasures.
