【摘要】 本文对环江肯福环境移民安置示范区所采 88个表层土样及 4个剖面土样有机质 ,全氮 ,全磷 ,全钾 ,水解氮 ,速效磷 ,速效钾 ,pH等指标进行了测定。结果表明该区表层土壤有机质含量较高 ,土壤氮相对丰富 ,钾含量偏低 ,磷严重缺乏 ,pH偏酸性。土壤剖面发育完整 ,在土壤剖面中有机质、氮、速效磷、交换性钾主要聚集在 2 0cm的表层土壤中 ,全磷随深度的增加而降低 ,全钾和 pH值则随土壤深度增加而上升更多还原

【Abstract】 Research was made on some indexes of soils in Northwest Guangxi. The soil indexes include soil organic matter, total nitrogen, total phosphorus, total potassium, hydrolysable nitrogen, available phosphorus, exchangeable potassium, pH etc.. Soil samples include 88 top soil and 4 profile samples, which were collected in Kenfu new settlement area of immigrants. The results showed that soil fertility in the area was characterized by abundant organic matter and nitrogen, low potassium and phosphorus, and strong acidity. Soil profile developed very well. The contents of soil organic matter, nitrogen, available phosphorus and exchangeable potassium in top soils were much higher than those in the lower horizons. The content of total phosphorus decreased with depth in the profiles, but the total potassium and pH increased in the same manner.更多还原
