| Abstract: | Objective]Effect of different site conditions on productivity of Chimonobambusa quadrangularis forest was studied to found the technical support of high-yield cultivation of C.quadrangularis.Method]The effect of different slope direction,slope position,altitude,soil depth on average yield of bamboo shoot,root diameter and bamboo height of Chimonobambusa quadrangularis were done in this paper.Result]The average yield of bamboo shoot,root diameter and bamboo height of C.quadrangularis of shading slope were better than that of half-shading slope and sunny slope;The average yield of bamboo shoot,root diameter and bamboo height of C.quadrangularis of down slope were better than that of middle slope and up slope;The average yield of bamboo shoot,root diameter and bamboo height of C.quadrangularis of altitude 400-600 m were better than that of altitude ≤400 m and altitude≥800 m;The average yield of bamboo shoot,root diameter and bamboo height of C.quadrangularis of soil depth 40-60 cm were better than that of soil depth≥80 cm and soil depth≤40 cm.Conclusion] Different site conditions has different influence on the bamboo root diameter and bamboo height of C.quadrangularis. |
