| Abstract: | An investigation was conducted to study the structure,biomass and soil characteristics of Salix integra pure and mixed stands under two cultivation patterns.Results indicated that the mean base diameter and mean height for the two cultivation patterns were 0.46-0.99cm and 130.44-187.61cm respectively.The pure stands had higher mean base diameter and mean height compared with the mixed stands with poplar I-69 of the same forest age.The average total biomass of the pure and mixed stands were 17.55t·hm-2 and 17.03t·hm-2,respectively.The foliar biomass was higher in the pure stands than in the mixed stands.However,the root biomass was adverse.The biomass of root(7.51t·hm-2) was the highest,followed by peeled stem(6.32),peel(2.42),and leaf(1.16).The contents of organic matter,total nitrogen and total potassium in different stands decreased with increasing depth of soil.There was no significant difference in nutrient content in the same soil layer between the pure and mixed stands.Correlation analysis demonstrated that the mean base diameter was significantly and positively correlated with mean height.The total biomass of S.integra stands had a significant positive correlation with available phosphorus in all soil layers,and organic matter in 10-30cm soil layer.There were different degrees of correlations between organic matter,total nitrogen,total phosphorus,available phosphorus,total calcium and total magnesium. |
