What are the skills for pruning apple trees in winter?

1, pay attention to branch rotation; Trees are cut down again, resulting in new branches and strong trees.

2. Look at the amount of buds: the amount of buds is large, the amount of pruning is large, and the degree is appropriately aggravated. Strictly control the ratio of flower buds to leaf buds at around 1:20; Young trees with few buds leave more flowers; Branches and branch groups without flower buds are pruned again to update the bearing branch groups.

3, look at the tree potential: strong trees are lightly cut, straight and strong, and stay aside to promote the formation of flower buds; Re-cutting down weak trees, removing weak branches and renewing weak old branches;

4. Look at varieties: varieties with strong budding ability and strong branching ability, such as Red Fuji and Guoguang, maintain moderate branching, adjust branching density, promote the growth of branch buds and flower buds at the back of the cut, and reduce nutrient consumption and fruit in different years. In the young tree stage, the strong and competitive branches and upright branches on the back are mainly thinned.

Late autumn and early winter are the best time to prune apple trees every year. At this time, it is still the stage of monthly fertilization. It is best to choose water-soluble fertilizer and microbial agent as monthly fertilizer to ensure the nutrient demand of apple trees during their growth.

Microbial inoculum+amino acid-containing water-soluble fertilizer is a widely used product in base fertilizer at present. It can improve soil, increase the growth speed of root system and improve the transport speed of nutrients.
