摘要
苗木标准化对林业生产现代化管理有重要意义。本文用实验统计方法,对柚木苗规格进行了研究,提出新的标准,与国家颁布的标准(1985,国家标准局)比较,造林成活率一样,立地条件差的更佳,造林后初期生长更优,苗木体积、重量分别减少12倍与11.3倍,育苗、造林费用降低4.3倍,经济效益提高5.2倍,节省造林总投资17.6％～22.0％。
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 %.
