Research on Growth Characteristics of Caragana korshinskii in Loess Hilly Area of Western Shanxi

Wu Xiujuan;Zhang Caihong;Ao Xiaoping;Yong Peng;Shanxi Academy of Forestry Sciences;  
Caragana korshinskii is a very important thrub in Loess Plateau. Study of the growth characteristics of Caragana korshinskii has great significance for management in Loess hilly area. Based on the data of the analytical trees,appropriate growth regularity models of branch diameter and branch height were established. The average increment and current annual increment curves were obtained to analyze the growth characteristics. The results showed that the Weibull model was the optimal model for branch diameter and branch height in Loess hilly area. The growth rate was relatively high when the branches age were between 4 and 9 years old. The current annual increments of branch diameter and branch height increased apparently at 8a,the highest value of average increment of branch height was 3 years earlier than that of branch diameter.Manual intervention should be adopted within 11 a in order to prolong the fast growing period and enhance the productivity of Caragana korshinskii forest.
