  • 【Objective】 In order to achieve the goal of scientifically selecting plots for planting bamboo under the forest,improving cultivation measures for bamboo under the forest,improving forest productivity,and promoting the development of the bamboo industry in Zhaotong City,Yunnan Province.【Method】 Chimonobambusa utilis forest planted under deciduous soft broad-leaved forests with different canopy densities was selected in Erxi Village,Taiping Town,Shuifu City,Zhaotong City,Yunnan Province. 5 clusters of Ch. Utilis were randomly selected to investigate the number of bamboo shoots,the diameter of bamboo shoots,the number of bamboo plants,the diameter and height of bamboo. 【Result】 The results showed that the influence on the number of shoots and bamboo plants was as follows:canopy density 0.3>canopy density 0.9>canopy density 0.6. The influence on the average ground diameter of bamboo shoots and bamboo ground diameter is as follows:canopy density 0.3>canopy density 0.6>canopy density 0.9. The results of the impact on bamboo height were as follows:canopy density 0.6>canopy density 0.9>canopy density 0.3. 【Conclusion】 The following conclusions can be drawn through analysis:there is a negative correlation between the shoot and ground diameter of young bamboo forests in Jinfo Mountain and the canopy density of soft broad-leaved forests.The canopy density of soft broad-leaved forest is consistent with the number of shoots and bamboo,with the maximum at a canopy density of 0.3. The height of bamboo is the highest when the canopy density of soft broad-leaved forest is 0.6. Through F test at 95% reliability,the canopy density of soft broad-leaf forest has no significant impact on the number of shoots,bamboo shoot diameter,bamboo number,bamboo ground diameter and height.
