Discussion on the Relevant Questions to Container Seedling of Afforestation Test

从试验区选择、作业方式和观测分析与结论等3方面,介绍了在黑龙江省金山屯林业局进行的云杉容器苗造林试验情况。结果表明:云杉容器苗的成活率、保存率、高生长分别比云杉常规苗的成活率、保存率、高生长提高11%、16.3%和2cm,在造林成本上前者比后者要高63%。通过综合分析得到结论,云杉容器苗造林可以大面积推广。

From the test area selection, mode of operation and observation analysis and conclusions from three aspects, in- troduced in Heilongjiang province Jinshantun Forestry Bureau of the Spruce Afforestation with container seedling test. The results showed that ： spruce container seedling survival rate, survival rate, high growth were higher than conventional spruce seedling survival rate, survival rate, high growth increased by 11%, 16. 3% and two centimeter, in afforestation costs up to 63 % higher than the latter; spruce plantation of container seedlings in the Bureau of big promotion, can also be extended to other area.
