摘要
2009年在国家测土配方施肥项目实施过程中,调查与分析了十堰市耕地土壤养分状况,与1982年的第二次土壤普查结果比较,2009年十堰市土壤的速效钾含量基本持平,有机质与碱解氮含量呈上升趋势,有效磷含量大幅度上升,而土壤pH值则下降明显。此外,还剖析了十堰市耕地养分变化的原因,并提出了提升耕地土壤养分含量的措施。
In the implementation of the national project of formula fertilizing by soil testing,the current situation of soil nutrient of the cultivated land in Shiyan city was investigated,analyzed and compared with the results of the second soil general survey in 1982.The results showed that： in comparison with the survey results of the year 1982,for the soil of Shiyan city in 2009,the content of available potassium was basically the same,the content of organic matter and alkaline nitrogen appeared a rising trend,and the content of available phosphorus increased greatly,but the pH-value decreased significantly.Otherwise,this article analyzed the reasons for the changes in soil nutrient of the cultivated land in Shiyan city,and put forward several measures for increasing soil nutrient content.
