筛选出集约管理、特殊管理、间作管理3种最佳丰产管理模式。集约管理模式、间作管理模式比粗放管理模式的树高分别增加44%、30%,胸径分别增加73%、46%,单株立木材积分别增加333%、178%,轮伐期分别缩短20年、15年;特殊管理模式较粗放管理模式的树高、胸径、单株立木材积分别增加56%、130%及724%,轮伐期缩短39年。各项差异性比较均达极显著水平。集约管理、特殊管理、间作管理3模式的大径阶分布比率大;粗放管理模式小径阶分布比率大。以间作管理模式的投资少,效益高
Screening out the intensive management, special management, inter-management of the three kinds of best yield management model. The tree height of intensive management and intercropping management increased by 44% and 30% respectively compared with the extensive management. The DBH increased by 73% and 46% respectively, and the stand volume per plant increased by 333% and 178% respectively and the rotation period decreased by 20% and 20% respectively. Year and 15 years. Tree height, diameter at breast height and stand volume per plant increased by 56%, 130% and 724%, respectively, and the rotation period shortened by 39 years. The differences were all reached a significant level. The large-diameter distribution ratio of intensive management, special management and inter-management 3 modes is large. The large-diameter distribution ratio of extensive management mode is large. Intercropping management mode, less investment, high efficiency
