Management of dormancy period of Begonia verticillata under inhibition of temperature drop

Tripterygium is not cold-resistant, and the temperature drops gradually after late autumn, and its growth is restrained. If we do not pay attention to management, it is possible to freeze to death, so it is necessary to strengthen the management of the dormant period of Begonia.

Begonia pruning

First, topdressing liquid fertilizer: in September, topdressing liquid fertilizer based on phosphorus and potassium fertilizer to promote flower bud differentiation of begonia.

Second, pick the fruit in time: if the fruit matures in October, it should be removed in time so as not to consume nutrients. Saving nutrients is beneficial to increase the number of flowers in the coming year.

Third, proper pruning: winter pruning in November to remove overlapping branches, withered and diseased branches, and adjust the tree shape to facilitate growth. Before germination in early spring, cut off disease and insect branches, withered branches and overdense branches in time; old plants, renew old branches by sawing off the upper end of large branches with few branchlets, germinating new branches, and then cutting off thin and weak branches. The wound caused by pruning is closed with a "callus preservative film" to protect the wound from dryness, cracking, diseases and insects. "Callus anticorrosive film" can restore the tree potential as soon as possible and control dry cracks and diseases and pests. It is easy to use and efficient.

Fourth, heat preservation and anti-freezing: enter the dormant period in December, do a good job of anti-freezing and warm work. Vertical silk begonia, sexual like sunshine, not shady, not very cold-resistant, at this time spraying "new high fat film" emulsion, once every 10 days, a total of 2 times, anti-freezing and cold-proof. The "new high fat membrane" is not a chemical fertilizer or a pesticide, but a plant surface protective agent, which is sprayed on the tree, will not produce drug harm, and can form a monolayer invisible to the naked eye, wrap the tree up, and protect it from the adverse environment of the outside world. play the role of anti-freezing and heat preservation, prevention of diseases and insect pests and so on.

Fifth, pest control: the main diseases and insect pests of Tripterygium are rust and brown spot, wax scale, apple aphid, red spider and so on. When clearing the garden, the combination of pruning, removal of disease and insect leaves and fallen leaves, concentrated destruction or deep burial, reduce the overwintering base of diseases and insect pests. Before the plant germinates, spray "tree protection general" + stone sulfur mixture to kill the overwintering eggs, heat preservation and anti-freezing. "Tree Protection General" can make the tree form a protective film, asphyxiating sterilization, suitable for protecting all kinds of trees and preventing virus replication and infection.

In order to create a good overwintering environment for Tripterygium, strengthen the management of the above five aspects in winter, heat preservation and anti-freezing, supplement nutrition, make it survive the winter safely.
