摘    要:用网格法结合村庄地块采集土壤样品,调查农民施肥状况.土样分析数据表明:南阳盆地土壤养分状况整体处于中等水平,土壤有机质、碱解氮、速效磷和速效钾平均质量比分别为14.63g/kg和68.62,16.20,76.26mg/kg,与第二次土壤普查结果相比有机质、土壤速效磷质量比分别提高了24.0%和200%,而土壤速效钾质量比下降了50.1%.调查资料表明:农民施肥存在肥料品种单一、施肥量、施肥方式等不合理问题,应重视有机肥施用,推广秸秆还田,采用复合和缓1控释氮肥及合理的施氮技术,注意减磷补钾.

关 键 词:南阳盆地  土壤养分  施肥调查

Abstract:Soil sampling was carried out by the net point way.Meanwhile,also was investigation about agricultural production conditions and peasant fertilization practice.Soil sample assay results showed that the soil nutrient was middling level in general.The average content of soil organic matter,Avail P,Avail N and Avail K were respectively 14.63 g/kg,and 68.62,16.20,76.26 mg/kg.Compared with results of the second soil overall survey,the soil organic matter and Avail P content were improved notably with 24.0 % and ...
Keywords:Nanyang basin  soil nutrient  fertilization investigation
