摘要
以杉木3代种子园为研究对象,分析不同坡向杉木3代种子园土壤有效养分含量差异,从而为实现杉木种子园的合理施肥奠定理论基础。研究结果表明,同一坡向随着坡位上升以及同一坡位随着土层深度的增加,杉木3代种子园土壤有效养分含量呈逐渐下降趋势;同一坡位同一土层深度不同坡向对土壤有效养分含量的影响体现出较为复杂的规律。
The third-generation seed orchard of Cunninghamia lanceolata was acted as research objects, the differences of soil available nutrient content at different slope were analyzed in this paper, so as to lay a foundation for reasonable fertilization to the third-generation seed orchard of C. lanceolata. The results showed that at the same slope direction, with the rising of the slope position and the increase of soil depths, soil available nutrient content of the third-generation seed orchard of C. lanceolata decreased gradually; At different slope direction with the same slope position and soil depths had complex effect on soil available nutrient content of the third-generation seed orchard of C. lanceolatca.
