Introduction of Xanthoceras sorbifolia to Glacial Margin of Lenglongling in Qilian Mountains
摘要
Abstract
Xanthoceras sorbifolia was introduced to 5 locations with different elevations (2 560,2 900,2 800,2 500,and 2 480 m,labeled as spot 0,spot 1,spot 2,spot 3,and spot 4,respectively) in Zhongmu Shandan Horse Husbandry Farm which is located in the glacial margin areas on the north slope of Lenglongling in Qilian Mountains.The height growth of the seedlings with the age of 1 to 3-year-old in 5 locations was in the order of spot 0＞spot 3＞spot 4＞spot 2＞spot 1.In spot 1,the current annual increments of the seedlings from seed sowing,root cutting,transplanting were all 0,and partial 0 in spot 2.The survival rates of overwinter of the underground parts of the seedlings were 100％.The average rate of the occurrence of dieback was in the order of spot 1＞spot 2＞spot 4＞spot 0＞spot 3 in which the rate of dieback of transplanting seedlings were slightly lower than others.Yellow leaf and seedling blight were found in some trial spots.It was concluded that spot 3,spot 0,and spot 4 were relatively suitable for the cultivation of X.sorbifolia.In spot 3,only one plant from seed-sowing with 4-year-old was found to fruit,and no flowering and fruiting were observed for 5-year-old seedlings.关键词
