| Abstract: | Ten kinds of main food of bamboo--Phyllostachys glauca ,P. aurita,p, sulphurea,P, pro- pinqua , Sinobambusa tootsik , Pseudosasa amabilis , Bashania f argesii , Indosasa patens, Pleioblastus maculates, Indocalamus latifoliusin, in Louguantai Experimental Forest Farm were analyzed regard- ing their mineral elements of Ca,Na,Fe,Cu,K,Mg,Mn and Zn. The result showed that the content of Ca ranged from （733.00±24.58）--（3406.19±119.21） ug g-1, with maximum in P. propinqua and minimum in P. aurita and significant difference（P〈0.05）;content of Na ranged from （148. 53± 17.27）--（ 1687. 60± 122. 32） ug g-1, maximum in Indocalamus latifolius and minimum in Pseudosasa arnabilis with significant difference （P 〈 0. 05） ; Fe content ranged from （935. 28 ± 43.83）--（345.33±46.25） ug g-1 ,maximum in Indocalamus latifolius and minimum in Pseudosasa amabilis with significant difference（P〈O. 05） ;content of Cu ranged from （56.23±10.96）--（346.50 ±13.04） ug g-1, maximum in P. glauca and minimum in Pleioblastus maculates,with significant difference （P〈0.05）;content of K ranged from （2410.32±90.28）--（7305.74±320.62） ug g-l, maximum in Sinobambusa tootsik and minimum in Indosasa patens, with significant difference （P〈 0.05） ;content of Mg ranged from （1830.42±86.57）--（ 5829.91±179.99）ug g-1, maximum in In- docalarnus latifolius and minimum in Pleioblastus maculates, with significant difference （P〈0.05） ; content of Mn ranged from （216.02±18.21）--（666.13±12.14） ug g-1 ,maximum in Indocalamus lati folius and minimum in Pleioblastus maculates, with significant difference （P〈O. 05） content of Zn ranged from （115.06±15.24）--（515.97 ± 56.28） ug g-1, maximum in Indocalamus latifolius and minimum in Indosasa patens ,with significant difference （P〈O. 05）. Correlations among the 8 ele- ments existed. |
