| 摘 要： | 2006年从广西河池市罗城县采集4061个耕层土样，分别进行土壤pH、有机质、全氮、速效磷和速效钾含量的测试和分析，并以1982年全国第二次土壤普查相关数据为基础，对该县耕地土壤肥力现状进行综合评价。结果表明，罗城县耕地土壤以微酸性为主，有机质、全氮、速效磷含量较丰富，其面积分别占耕地总面积的88．41％、90．86％、86．36％；土壤缺钾严重，其面积占耕地总面积的75．08％。针对该县耕地土壤酸化、缺钾严重的现状，提出增施有机肥、合理施用钾肥、推广测土配方施肥、加快中低产田（地）改造以及合理调节土壤酸碱平衡等措施，以提高耕地土壤质量，实现农业生产可持续发展。

| Abstract: | In 2006, 4061 soil samples of arable layer were collected from Luocheng City, Hechi, Guangxi, and were analyzed for pH, organic matter, total nitrogen, available P and available K. The soil fertilizer of arable land in Luocheng County was evaluated comprehensively according to the related data of the second national soil investigation in 1982. The results indicated that arable land soil in Luocheng was sub-acidic, the content of organic matter, total nitrogen and available phosphorus were sufficient and accounted for 88.41, 90.86 and 86.36% in total arable land area, respectively. The available potassium was severely deficient and accounted for 75.08% in total arable land area. Keeping in view of the acid- ification of soil and potassium deficiency in arable land in Luocheng County, use of high organic fertilizer and sufficient potassium has been suggested. Application of fertilizers on the basis of soil testing should be practiced, the reformation of field （land） with low-medium yield should be accelerated and the acid-base balance in soil should be regulated to enhance the quality of soil for sustaining the agricultural production. |
