1. For branches that have been frozen in winter, they should also be pruned, and pay attention to disinfection and sterilization of branches' incisions, and at the same time, apply healing agent to larger incisions. Special attention should be paid to the seedlings of Aceraceae, which should be pruned after the leaf buds germinate. Premature pruning will cause serious bleeding.

2. According to the weather conditions, in case of extreme weather, immediately spray antifreeze to strengthen protection. Seedling windproof tents and insulation materials wrapped in tree trunks should be removed in the first half of April.

3. According to the variety of seedlings, spray 3-6 Baume lime-sulfur mixed solution for sterilization, egg killing and wintering spore killing, so as to reduce the occurrence of pests and diseases.

Extended data:

In the post-beginning of spring period, seedlings gradually stopped dormancy, juice began to flow, flower buds and leaf buds of trees began to germinate, some eggs began to hatch, and pathogen spores began to multiply. In addition, trees themselves have poor adaptability to the spring environment, and are easily affected by drought, low temperature, freezing and strong wind, and are also vulnerable to pests and diseases. Therefore, it is particularly necessary to strengthen the management of tree conservation in spring.

Pruning and shaping will be carried out in winter from 65438+February to March next year to cultivate beautiful trees. In spring, the dead branches, clustered branches, clustered branches, cross branches and pest branches of seedlings can be pruned continuously.
