2, soil control tips. In winter, soil can be cultivated under the tree tray to increase the surface temperature and humidity and enhance the root absorption capacity. Pay attention to cleaning the branches and leaves of diseases and insect pests under the crown before soil cultivation, and then soil cultivation after spraying sulfur mixture. The flower bud differentiation of Myrica rubra plants began in late July, and the autumn shoots germinated late. By the second year, most of these autumn shoots had stopped flowering or had few branches, which consumed a lot of nutrition. Therefore, it is necessary to control the autumn shoots, cut them dry at the critical stage of flower bud differentiation, and then apply healing agents to make Myrica rubra blossom and bear fruit every year.
3, plastic trimming. In winter, pruning is also an extremely important job. For normal fruit trees that have not been pruned, it is necessary to remove pests and diseases, dead branches and weak branches in time, trim dense branches, upright branches and overlapping branches in the crown at the same time, and also appropriately trim the non-flowering branches outside the crown.
4. For the normal fruit tree that has been shaped, just cut off the branches of diseases and pests, dead branches, residual branches, weak branches, cross branches, dense branches, overlapping branches and mopping branches, and the rest branches should be cut as little as possible. For young trees, it is mainly to shape the tree type, which can be pruned according to the actual situation of young trees. After pruning, the cut branches and leaves should be cleared out of the garden, and at the same time pay attention to wound protection to prevent pests and diseases and rainwater pollution.
