对二滩水电站红格移民安置区新垦地的土壤肥力进行了较为系统的研究。研究结果表明，与当地土壤肥力水平相对较高的菜园土和水稻土相比较，红格移民安置区新垦地土壤有机质含量极低为４．０８～４．３９９／ｋｇ，腐殖质仅占有机质含量的３．７３％～７．１５％，微生物数量少５土壤粗骨性强，＜０．０１ｍｍ土壤物理性粘粒的团聚度仅为１０．４％～２８．９％，土粒分散性强，水土流失严重；土壤保水性弱，水分蒸发损失大，土壤干旱较其他区域土壤更为严重；各种养分包括全 Ｎ、 Ｐ、 Ｋ和有效 Ｎ． Ｐ、 Ｋ，微量元素 Ｂ、 Ｍｏ、 Ｃｕ、 Ｚｎ、 Ｆｅ、 Ｍｎ缺乏或严重缺乏。以土壤培肥和节水、抗旱为核心的高产高效综合农业技术的应用是二滩水电站红格移民安置区移民稳定安置的基本保障．
The soil fertility of newly reclaimed land in Hongge resettlement area of Ertan Hydropower Station was systematically studied. The results showed that the soil organic matter content of newly reclaimed farmland in Hongge resettlement area was very low from 4.08 to 4.399 / kg compared with that of the vegetable garden soil and paddy soil with relatively high soil fertility. The humus content was only the organic matter content Of the soil microbial clay was 3.73% ~ 7.15%, the number of microorganisms was less than 5%. The cohesiveness of soil physical clay was only 10.4% ~ 28.9% , Serious soil erosion; soil water retention is weak, water evaporation loss is large, soil drought more serious than other regions of the soil; all nutrients include all N, P, K and effective N. P, K, trace elements B, Mo, Cu, Zn, Fe, Mn deficiency or serious lack of. The application of high-yield and high-efficiency integrated agricultural technology with soil fertility-raising and water-saving and drought-resistance as the core is the basic guarantee for the resettlement of migrants in Hongge resettlement area of Ertan Hydropower Station.
