大樟树移植养护技术（Large camphor tree transplantation maintenance technology） Large camphor tree transplantation maintenance technology Transplanting and maintenance of big trees is a highly technical work, and a slight neglect in every aspect of transplantation and maintenance will result in non - salvage losses. In the past two years, the large camphor trees transplanted by the authors units all survived and grew well. The experience is summarized as follows: I. factors to be considered before transplantation 1., tree procurement should be near, not far from the large camphor tree transplant, mostly for the nearest purchase. If the procurement is too far, the difference in soil properties is too large, the transplant trees will not acclimatized. In addition, the transportation is too far, easy to cause trunk drying and root drying dehydration, long-distance transport of bumps easily soil ball broken, in addition, long-distance transportation will increase transportation costs. The growth rhythm of 2. spring planting large camphor tree with respect to young seedlings to slow, so it is very important to choose the transplanting season. During the transplanting period of large camphor trees, it should be said that spring is better than autumn and winter. To pass the test of the winter in autumn and winter transplanted camphor, wound healing tissue can produce, whether to grow new roots, because in the winter, can not response to the adverse environment reflected in a timely manner, can not take the necessary remedial measures. But in the transplantation, the temperature rose, camphor quickly into the growth of wound healing, growth, new shoots root production is more favorable, at the same time, observe the tree growth conditions are much easier to find problems in a timely manner, timely remedy. 3. root pruning and root injury that cut the root of trees but the survival rate is high. Many articles about the importance and method of tree root. In recent years, from the field
