Abstract

Based on the fact that Cunninghamia lanceolata (Chinese fir)litter decomposes slowly , the effects of different control measures on the decomposition of Chinese fir litter were studied .The results implied that different control measures had different effects on the decomposition of Chinese fir litter .The burying of Chinese fir litter could quicken its decomposition .The mass loss ratios of leaves and branches were 46.5 % and 32.0 % respectively , 14.5 % and 38.5 % higher than those put on the ground .Different N fertilizers had different effects on the decomposition rate of Chinese fir litter .When applying NO-3 -N , the annual mass loss ratio of Chinese fir litter was 46.0 %, 13.3 % higher than those without nitrogenous fertilizer (control group).While applying NH+4 -N , the annual mass loss ratio was 40.7 %, approximate to the control group .Burying under the ground and applying NO-3 -N could significantly improved the decomposition rate of Chinese fir litter and shorten the decomposition time by 50 % and 95 % respectively .[ Ch , 4 tab .14 ref .]
