Effect of Bamboo Density on Shoot Yield of Chimonobambusa Pachystachs Forest
In order to study the effects of different bamboo density on shoot yield of Chimonobambusa Pachyst-achs forest,five density levels were set up,which were 1:45000 plants/hm2,2:52500 plants/hm2,3:60000 plants/hm2,4:67500 plants/hm2 and 5:75000 plants/hm2,respectively.The differences in the number of bamboo shoots,the proportion of bamboo shoots at different stages,the yield of bamboo shoots and the growth status of new bamboo were investigated.The results showed that with the increase of bamboo density,the number of bam-boo shoots,the proportion of early bamboo shoots and the number of bamboo shoots increased gradually.The proportion of middle bamboo shoots and the yield of bamboo shoots increased first and then decreased.The yield was the highest when the density was 67,500 plants/hm2.Therefore,reasonable bamboo density can significantly increase the yield of bamboo shoots,and it is most suitable for the high yield of Chimonobambusa Pachystachs forest when the density is 67500 plants/hm2.
