Biomass and nutrient accumulation of poplar plantation on beach land in Yangtse River in Anhui province

Abstract

Abstract: The authors summarized biomass pattern and production of Ⅰ-69 poplar clone plantation on beach land in Anhui province and built mathematical models for biomass with DBH and height as well.Meanwhile the LAI dynamics of the plantation was analyzed.The biomass of 11-year plantation of poplar on beach land was 90.2 t·hm^-2,its production 8.2 t·hm^-2·yr^-1 for plantation and 21.59kg·yr^-1 for single trees.Compared to the plantation at general sites in Jiangsu province,the production for individual on beach land was as 50% as higher.Its LAI was 3.32 m²·m^-2,and the net LAI increasing reached highest level in 3 years after planting.Meanwhile the stand productivity was getting into highest too.To produce one ton biomass,it needed the following materials:N 3.369kg,P 0.327kg,K 2.424kg,Ca 7.465kg,Mg 0.525kg,Cu 0.00573kg,Mn 0.0186kg,Fe 0.111kg,Zn 0.000268kg;and absorbed S 0.72kg,Cr 0.000252kg,Cd 0.00039kg,Pb 0.00043kg.Statistical analysis for element content in annual rings indicated that there was negative relation between N and K,but positive for N and P.The inundation time had significantly positive influence on content of P and N,but negative to K.

Key words: Biomass, Productivity, Nutrient, Heavy metals, Ⅰ-69 clone poplar, Beach land, dryland, planting green manure, straw retention, plastic film mulching, nutrient concentration, winter wheat, yield
