Field experiments were conducted to study the effects of nitrogen,phosphorus,potassium fertilizers and soil fertility on the nutritive composition of bamboo shoot.The results obtained showed that the bamboo shoat had much higher contents of total.and essential,amino acids than ather common vagetables.The free amino acids contents were higher in winter bamboo shoot than those in spring bamboo.The free glutamine and aspartate were the major delicious amino cids of the former,gl-atamate and aspartate were the major delecious amino acids of the latter.The hydrolytic and free amino acids contents of bamboo shoot were enhanced by N,P or K fertilization.But the sugar content was decreased with application of N fertilizer and increased with phosphorus addition.The results also indicated that the hydrolytic amino acids in winter bamboo shoot had a significantly positive correlation with soil available N,but no significant relation with K and P were observed.In addition,the free tryrosine content,which always resuits in turbidness of the canned bamboo shoot,was lowerd with increasing soil N or P conlient and fertilizer rates of N or P.
