Abstract: Based on the difference analysis on nutrition contents such as crude protein,crude fat,crude fiber,ash and dry matter,in different samples (control sample and cutting sample) and different parts (stems,branches and leaves) of the 1^st and 2^nd year(s) regeneration bamboo after strip thinning the results show that:1) after strip thinning,cutting sample of nutrition contents,such as crude protein,crude fat,dry matter and ash,is higher than control sample,crude fiber opposite.2) after strip thinning and comparison with 1^st year bamboo and 2^nd year bamboo,protein content decreased,crude fat and ash content decreased in stems and branches,increased in leaves;crude fiber content increased in branches,decreased in leaves;and dry matter increased.These results provide a scientific basis for artificially regenerated bamboo forest and explain feeding behavior of giant panda.
