- Abstract:
-
Based on the harvesting of standard trees in sample plots,biomasses of Hippophae rhamnoides L.-forest on converted land was studied in Huangshui river at Qinghai province.The results showed that its biomass ranged from 1 895.94kg/hm2 to 17 219.54kg/hm2.The ration of the biomass of above ground parts is 56.20%~79.25%,and the others is 20.75%~43.80%.The biomass distributing sequence of different organs is root>trunk>branches> leaves.There is a synergistic phenomenon between its biomass and its height,diameter and crown width.The law of biomass increased with the age is consistent with the Logistic growth model,in which 8 a is the fastest growth,the biggest economic factor,and the best period for stand tending.The biomass changes under different site conditions are quite different.Rainfall,soil moisture content and biomass changes were consistent.The single genotype,the ration of the biomass of above ground parts and the index of clonal growth form of the population at high level of soil moisture supply were higher than that of the population at low level of soil moisture supply.
