Abstract
One year experiment were conducted on decomposition of Aleurites montana and Phyllostachys pubescences mixed foliage litter samples in a 16-year old A.montana plantation.The litter samples included: A as 100% A.montana foliage,B as 100% P.pubescences foliage,C as mixture of 50% A.montana and 50% P.pubescences foliages,D as mixture of 75% A.montana and 25% P.pubescences foliages and E as mixture of 80% A.montana and 20% P.pubescences foliages.The effects of the mixed foliage litter decomposition on the activity of soil enzymes and the release of organic C,N,P,K,Ca,Mg,Na,Mn and Zn were studied.The results indicated that after one year’s decomposition,the release of N,P,K,organic C,Na,Ca,Mn,Mg and Zn from the foliage litter samples varied significantly.In the 5～10 cm soil layer,the activity of invertase and catalase were higher than those at the other soil layers,with the invertase activity order of E C A CK D B and the catalase activity order of E CK B D A C.The litter sample E was proved to have positive effects on activity of soil invertase and catalse.Therefore,in silviculture practice,the mixed plantation of 80% A.montana and 20% P.pubescences could be recommended to optimize the soil quality and fertility and facilitate growth of the both species.Fig 2,Tab 2,Ref 37
