【Abstract】 This study presents high-yielding culture techniques for mearns acacia ( Acacia mearnsii ) on the basis of a 5-year project. The measures for seedling strengthening, site classification, planting density, management of forested land, yield targets, as well as forecast of economic benefit are shared. The test stands of 4 year and 2 month-old, considering the tree height, breast-height diameter, and yield, reached the level of site class 11 and site class 9 in the provincial targets for a 6 year-old stand.更多还原
