摘要
【目的】通过分析采伐带毛竹(Phyllostachys edulis)新生竹叶片非结构碳水化合物及新生毛竹地上器官生物量,以寻求提高毛竹抵抗带状采伐干扰能力的最佳施肥模式。【方法】采用正交试验设计(将初次带状采伐的保留带作为此次的采伐带,初次带状采伐的采伐带作为本次的保留带),以采伐带宽、稀土用量及复合肥与生物炭肥比例为三因素三水平的试验,对不同施肥模式下的毛竹叶片非结构碳水化合物及地上部分各器官生物量进行分析。【结果】研究表明带宽是影响采伐带毛竹叶片可溶性糖及地上生物量的重要因素。【结论】提高采伐带毛竹抵抗带状采伐能力的最佳施肥模式为A2B2C2,即带宽为8 m、稀土用量为35 kg·hm^(-2)、复合肥与生物炭肥的比例为7∶3。
【Objective】Through analyzing the non-structural carbohydrates of the leaves and aboveground organ biomass of neonatal bamboo in the cutting zone,the best fertilization mode was sought to improve the resistance of bamboo to the disturbance of strip cutting.【Method】In this study,the orthogonal experimental design was adopted(the reserved zone of the first strip cutting was used as the current cutting zone,and the cutting zone of the first strip cutting was used as the current reserved zone),and the experiments of three factors and three levels,i.e.the cuttingstrip width,the rare earth fertilizer dosage and the ratio of compound fertilizer to biochar fertilizer were carried out,so that the non-structural carbohydrate of the leaves and aboveground organ biomass of Moso bamboo(Phyllostachys edulis)under different fertilization modes were analyzed.【Result】The results showed that the cuttingstrip width was an important factor affecting the soluble sugar and aboveground biomass of bamboo leaves of the cutting zone.【Conclusion】The best fertilization mode to improve the resistance of bamboo leaves to strip cutting was A2B2C2,that is,8 m,35 kg·hm^(-2) rare earth fertilizer dosage,and 7∶3 ratio of compound fertilizer to biochar fertilizer.
