摘要
以江西省永丰县官山林场和井冈山市长坪林场不同施肥类型的毛竹林为研究对象,以不施肥毛竹林为对照,研究了施肥对毛竹林生物量及其固碳潜力的影响。结果表明：施肥显著提高了毛竹林乔木层生物量,且与对照相比提高了竹秆生物量占总生物量的比例。不同施肥类型毛竹林乔木层碳储量为25.88-40.25 t/hm2,施肥样地碳储量均大于对照样地,与施肥对毛竹林乔木层生物量的影响一致。毛竹林具有较强的固碳能力,应该采取合理的施肥措施,以提高毛竹林的生产力并增强毛竹林的固碳潜力。
To study the biomass and carbon sequestration potential under different fertilization types of Phyllostachys edulis forests, taking the non-fertilized Ph. edulis forests as the control, experimental field at Guanshan Forest Farm in Yongfeng County and Changping Forest Farm in Jinggangshan City, Jiangxi Province. The results showed that： fertilization could increase the tree layer biomass of Ph. edulis forests significantly. Compared to control, fertilization could increase the proportion of stem biomass to total biomass. The carbon storage of standing bamboos ranged from 25.88 to 40.25 t/hm^2 under different fertilization types of Ph. edulis forests, and the carbon storage of fertilization better than non-fertilization.The influence of fertilization to biomass and carbon storage is consistent. Ph. edulis forests can be a lot of carbon dioxide sequestration and a large carbon pool. It is necessary to take reasonable fertilization measures for improve the productivity and carbon sequestration potential of Ph. edulis forests.
