Introduction of Eriobotrya japonica L.in peakcluster limestone area of West Guangxi,China

The introduction experiment of two varieties of Eriobotrya japonica named Zaozhong and Changhong were done in Sanzhiyang Region——a typical limestone area in Du’an County,Southwest China. The results indicated that these two varieties completely adapted to the climate and environment of the introduced region. The trees grew rapidly and 80% of them flowered in the third year after being introduced. They represent good characters of young-fruiting and prematurity. Average yield of a tree was over 10 kg. Quality of the fruit was also excellent. Outputs of Zaozhong and Changhong varieties were 7 875 kg/hm~2 and 8 400 kg/hm~2,equivalent to 47 250 and 50 400 Yuan in value,and net incomes were 35 250 and 38 400 Yuan respectively. Furthermore, the grown-up E.japonica trees added the woodland area in local villages and improved field microclimate in and around the orchards. It shows that there are significant benefits in economy, sociality and ecology after introducing E.japonica in peak cluster limestone area of West Guangxi.
