The picking and pruning of camellia can be completed in February and August every year. Using sharp scissors after disinfection and sterilization, the young leaves growing around the top of camellia are cut off, and the growth of the top is controlled, which is beneficial to the germination of new branches of plants. After pruning, spray fungicides on camellia to solve the germs on the plants.
Pruning camellia can be done every winter, when the plant is dormant, and pruning can keep the beauty and elegance of the plant. In the process of pruning, it is necessary to cut off overlapping branches, diseased branches and dead branches of camellia, and then cut off blind branches.
Summer thinning and pruning, high ambient temperature, hot gas. At this time, it is necessary to complete thinning and pruning of camellia, and trim its overgrown branches to improve the air permeability between plants. When pruning, priority should be given to pruning branches near the roots, and then pruning branches that are too dense at the top.
Light pruning: in the spring pruning time, complete a light pruning on the picking surface of the trunk to make the trunk neat and consistent and promote the growth of buds and leaves. Each light cut is 3 ~ 5 cm higher than the last cut, and all the branches at the upper end are cut off. For branches with more buds, they need to be pruned again to reduce the damage of nutrients and ensure the working ability in bud stage.
Deep pruning technology: After picking branches and buds several times, there will be more dense twigs at the top of the trunk, and more solid tumors will appear in the twigs, which will hinder the transportation of nutrients and make the buds grow thinner and thinner, which will seriously endanger the yield and quality of the branches and buds. Therefore, after picking the branches and buds of Jinhua tea tree for many years in spring, it is necessary to prune with a depth of 1 depth, that is, to prune a layer of fine hair branches with a depth of 10 ~ 15 cm at the upper end of the trunk to repair the upward trend of the plant, level the picking surface and improve the yield and quality of the branches and buds.
Management method in the middle and late stage "After the camellia is pruned, it can be watered once to let the plant repair and grow. When watering, it is not advisable to let water contact the incision of camellia to prevent the incision from rotting. It is also necessary to apply the soaked organic fertilizer to Camellia once to supplement its vitamins and let the plants grow new branches as soon as possible.
Trimming: the time of trimming should also be combined with the collection of cuttings, and the time of trimming branches before cutting seedlings should be closely combined to improve the comprehensive utilization rate of branches. Fertilize immediately after pruning, mainly with phosphorus and potassium fertilizer to promote long roots and leaves. In addition, potassium dihydrogen phosphate can be sprayed on leaves frequently to promote the growth of roots and buds.
