马尾松施肥对林木生长效应

Effect of Fertilization on Growth of Pinus massoniana Forest

根据林地肥力监测结果与有关施肥研究的报道 ,对马尾松施肥的阶段性、时效性、敏感性、适应性作一综述性的介绍。马尾松的施肥效应是肯定的 ,三要素施用后显示效应的总趋势是 :P >K >N。我国南方红、黄壤林地土壤普遍缺P ,因此施P特别见效。针对林木生长的不同阶段 ,幼林期施用P肥为佳。

This paper summarily introduced the fertilization phases, fertilization ageing, sensitivity and adaptability of Pinus massoniana to fertilization ,according to the determination of fertility of forest land and reports on fertilization.The total tendency of fertilization effect was that, P>K>N. In the south of China, the red-soil and the yellow-soil forest land were poor in phosphorus, so fertilization of phosphorus had special effect.
