摘　　要：以杉木为研究材料,探讨在同一纬度区域、立地条件较为一致的天峨县林朵林场、融安县西山林场、融水县贝江河林场施用基肥和不施用基肥处理对杉木1~3年生长量及对应地块土壤有效养分含量的影响,分别在种植1、2、3年后测定其树高、胸径及对应土壤pH值、有机质及速效氮、磷、钾、有效铁、硼等指标。结果表明:施用基肥处理促进了杉木平均树高、胸径的增长,显著或极显著提高土壤碱解氮、有效磷、速效钾等养分有效含量,有利于提高土壤综合肥力系数;试验区地块磷、钾有效养分含量较低,施用基肥后土壤速效钾养分得到缓解,但土壤有效磷养分仍严重缺乏。This study explores the effects of applying base fertilizer and not applying base fertilizer on the 1-3 year growth of Cunninghamia lanceolata and the corresponding soil available nutrient content in the same latitude area and site conditions in Linduo Forest Farm of Tian′e County,Xishan Forest Farm of Rong′an County,and Beijianghe Forest Farm of Rongshui County.The tree height,diameter at breast height and corresponding soil pH,organic matter and available N,P,K,available Fe,B and other indicators were measured after planting for 1,2,and 3 years respectively.The results showed that the application of basal fertilizer promoted the growth of average height and DBH of Cunninghamia lanceolata,significantly or extremely significantly improved the effective contents of soil available N,P and K,and improved the comprehensive fertility coefficient of soil;the content of available P and K nutrients in the experimental plot was low,and the available K nutrients were alleviated after the application of base fertilizer,but the available P nutrients were still seriously lacking.
