摘要
[目的]研究不同立地因子对四方竹生产力的影响,从而为四方竹丰产栽培奠定技术支撑。[方法]分析了不同坡向、坡位、海拔及土层深度等立地因子对四方竹笋产量、地径及竹高等指标的影响。[结果]阴坡四方竹笋产量、平均地径和平均竹高等指标优于半阴坡和阳坡,下坡四方竹笋产量、平均地径和平均竹高等指标优于中坡和上坡,海拔400～600 m四方竹笋产量、平均地径和平均竹高等指标优于海拔≤400 m及海拔≥800 m,土层深度40～60 cm四方竹笋产量、平均地径和平均竹高等指标优于土层深度≥80 cm及土层深度≤40 cm。[结论]不同立地因子对四方竹产量、平均地径、平均竹高均有不同的影响。
[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.
