Afforestation Techniques and Result Analysis of Fast-growing and High-yield Forests of Cunninghamia lanceolata

In this paper the demonstration forests of Cunninghamia laneeolata planted in 2004 in Nanhe Village, Muzhen Township of Qingyang County were selected as the example and the effects of technique application in fast-growing and high-yield forests of Cunning- hamia lanceolata on the stand quality and timber production were analyzed. The results showed that by adopting intensive management measures including careful tillage, fine variety and strong stock, careful planting, management and protection, etc., the average height, DBH, basal diameter and stand volume of the demonstration forests have increased significantly and brought remarkable benefits compared with stands with the same site conditions and general afforestation measures.
