| Abstract: | A study was carried out to determine the production,component and seasonal dynamics of litterfall in a Ormosia xylocarpa plantation located in Xinkuo Teaching Tree Farm in Sanming of Fujian province,which was planted in 1967 In 1999 and 2000,about 15 692 344 kg·hm -2 litter production was returned to the plantation soil,in which 60 05%, 16 71%,0 19% 0 07% were occupied by leaves,branches,flower,fruit,and 10 44%,8 54% were occupied by other tree litters and other litters respectively Total litter production changed obviously in one year and another Litter production in 2000 year were 1 71 times as higher as 1999 year and monthly litter production both peaked in March and April or August with the highest in March Litter production changed in the order of spring>summer>autumn>winter |
