? No fertilization is needed after pruning. The first fertilization of Myrica rubra 1 time is in February-March before germination. Potassium fertilizer and nitrogen fertilizer are mainly applied, and each plant can be applied with 50 grams of Henry water-soluble fertilizer, which is beneficial to meet the nutrient requirements of Yangmei spring shoot growth, flowering and fruit growth. The second application of strong fruit fertilizer, mainly quick-acting potassium fertilizer, can supplement the nutrient demand of fruit growth and development in time, which is conducive to improving fruit quality. Fertilization from June to July after the third fruit harvest, mainly applying organic fertilizer and available nitrogen fertilizer, is conducive to timely supplementing the nutrients needed by trees. Three times accounted for 30%, 30% and 40% respectively. If fertilization is applied twice a year, it can be applied before 1 germination, accounting for about 40%, and the second time can be applied after fruit picking, accounting for about 60%. Let's talk about the pruning technology of Myrica rubra.

1: Thinning: Generally, branches or branches are cut off from the base of branches, and auxiliary branches that grow too densely can be removed, leaving weak branches; Cut off the upright branches on the back of the main branches and auxiliary branches, the thick branches at the top of the crown, or the redundant branches when the crown is formed. Short cutting: a part of branches can be cut off from the middle of branches, which is beneficial to promoting multiple new shoots, renewing fruiting mother branches and restoring the growth of weak trees. Branch pulling: Horizontal branch pulling helps to open the crown of the tree, make the sunshine transparent, relieve the tree vigor, not only promote the differentiation of flower buds, but also improve the fruit setting rate and bear fruit early. Ring cutting: In the process of ring cutting, the branches in a certain position are cut deep into the xylem with a knife, which is beneficial to the middle-aged and young Myrica rubra trees with overgrown weeds and difficult to form flower buds. After girdling, the products of photosynthesis remain in the upper part, which is beneficial to promote the formation of flower buds and improve the fruit setting rate and yield.

2. Precautions: Plastic pruning is also to reduce unnecessary tree consumption. For Myrica rubra with normal pruning results, the branches of diseases and insect pests, dead branches and weak branches should be subtracted; For those normal fruit trees that have been shaped, only the pests and diseases that must be cut off can be subtracted, and the remaining branches should be cut as little as possible to ensure that the trees can produce enough photosynthetic products; Young Myrica rubra trees need pruning from the third year to avoid damaging young branches.
