Forestation concepts and practices developing in New Zealand
In New Zealand government and industry are developing a new nursery system backed by substantial research facilities and budget. Beds of radiata pine are precision sown and thinned to square spacing of 7 x 7 cm. This permits "box pruning" which is horizontal undercutting plus vertical root pruning along and across the bed. When lifted, a box-pruned seedling retains virtually all of its roots, and almost every tree is shippable. Since culling and counting are not necessary seedlings can be lifted and packed in the field, eliminating the need for a packing shed. Reduction in exposure and handling of seedlings increases plantation survival and initial growth, and promises to reduce rotation age by 1 year and decrease nursery costs.
