Standard of Teak Stump And Its Economic Benefit

Standardization of nursery stock is very important for modernization of forestry production management.After studying the standard of Teak stump with experiment statistics,a new standard which is different from the national one promulgated in 1985 was put forward.According to the new standard,the afforesting survival percentage is as high as that of national one,or even better grown in the inferior conditions,and the initial growth of the stump is much better after planting.Besides,it can also reduce the volume and weight of seedlings by 12 and 11.3 times respectively,reduce raising and planting cost by 4.3 times,enhance the economic benefit by 5.2 times and save the total afforestation investment by 17.6%~22.0%.
