Comparison on Growth Characteristics in Two Regeneration Patterns of Eucalyptus urophylla×E.grandis Plantation in Southwest Guangxi
摘要
Abstract
The growth characteristics of Eucalyptus urophylla×E.grandis plantations in two regeneration modes (planting regeneration and sprout regeneration)were investigated by permanent plots method in Ningming county of Guangxi.Results showed that the growth of E.urophylla×E.grandis was rapid.The average diameter at breast height(DBH),height and volume of 4-year-old planting stand were 11.7 cm,17.0 m,0.090 7 m3,respectively,and the average DBH,height and volume of 4-year-old coppice were 12.0 cm,17.7 m and 0.097 4 m3,respectively. The average height,DBH and volume of 1-year-old to 4-year-old coppices were significantly higher than those of planting stand. Therefore,sprout regeneration was a kind of manage-ment method which was easier to expound fast-growing characteristics than planting regeneration.关键词
