Improving the transplanting of Douglas-fir container stock in Coastal British Columbia Zhang, Yinjie

Abstract

Seedling transplanting is a significant important part of silviculture system. Some experimental evidences show that nutrient and moisture availability, site fertilization, planting operations, root damage, transportation and storage between lifting and planting have impacts on seedling quality and field performance after outplanting. This article focused on the problems occurred during production, shipping and planting of Douglas-fir seedling in coastal British Columbia. This article provided some suggestions for problems occurred in each period during seedling transplanting. The primary focuses are mycorrhizal inoculation of nursery stock, site fertilization, and keep seedling quality and vigour during transportation and storage. This article also discussed the economic considerations, and cost-effective operations and treatments during seedling transplanting. Recommendations of increasing Douglas-fir seedling growth and survival are discussed in this article. Mycorrlizal inoculation program of Douglas-fir container seedlings is better to be conducted, since mycorrlizal inoculation offers better chance for seedling growth and survival. Spot fertilization is recommended for Douglas-fir stands in coastal British Columbia. Spot fertilization is more specific, and can avoid increased growth of non-crop plants. This article also discussed a nutrient liquor containing micromolecule that can increase seedling quality and keep vigour. The nutrient liquor has been proved can enhance root growth of agriculture crops, and increase plant vigour. Further studies are still needed to apply it to forestry crops. Apart from those major focuses, some operational tips during seedling production, transportation and storage also should be noticed.
