华南人工林凋落物养分及其转移

摘要/Abstract

摘要： 对华南5种人工林凋落物量、凋落物养分及绿叶养分含量的测定结果表明,各种人工林凋落物量大小依次为:马占相思(11.1t·hm^-2)>湿地松(7.3t·hm^-2)>荷木(6.5t·hm^-2)>大叶相思(4.8t·hm^-2)>柠檬桉(2.6t·hm^-2).马占相思通过落叶回归土壤的养分量高于其它类型.5种人工林均通过养分转移机制,大量从枯老叶中转移N、P、K养分,其中马占相思转移的养分量最大,营养转移的季节性差别较大.各种人工林对其它元素的转移现象不确定.

Abstract: The amounts of litterfall,nutrient content in it and leaves of five plantation forests in south China were determined.The order of litterfall biomass was in sequence of Acacia mangium (11.1t穐m^-2)> Pinus elliotii (7.3t穐m^-2)> Schima superba (6.5t穐m^-2)> Acacia auriculaiformis (4.8t穐m^-2)> Eucalyptus citriodora (2.6t穐m^-2). A.mangium returned soil much more nutrient to soil through litterfall than other forests did.N,P and K were largely translocated from senescing leaves for all the five forests, and especially for A.mangium.Nutrient translocated varied greatly with seasons.The translocation of other elements was not definite.

Key words: Plantation, Litterfall, Nutrient, Nutrient translocation
