Effects of Coppice Management on Growth and Tree Shape in Gingko Leaf-producing Plantation in Jiangsu Province, China
摘要
Abstract
In order to improve the yield and quality of Gingko leaf-producing plantation, coppice management of 1,2,3-year-old Dafuzhi (one of Gingko varieties) seedling at different stump heights (or top pruning) was taken in March, 1997. The following conclusions were drawn on investigation of growth and tree shape at the end of the first year: (1) Coppice management could lower Gingko tree height, reduce crown height, and enlarge crown diameters and crown volumes for some treatments.(2) Long branch number and length per plant of some treatments were increased by coppice management. (3) The main indexes which affected leaf yields were root diameters, long branch number, long branch length, the ratio of seedling height to crown diameter, and the ratios of crown diameter to leaf layer depth. So the good quality tree shape could be formed by coppice management.关键词
