The latest cultivation techniques and methods tutorial for dwarf apple trees

Dwarf apple trees are currently a cultivation trend. Dwarfed fruit trees are easier to manage and easier to harvest. They can shorten the time to fruiting. They have many advantages, so dwarf cultivation is now generally used. How to cultivate dwarf apple saplings, and what to pay attention to, let us now look at the specific cultivation methods together.

1. Seedling raising methods

When cultivating rootstock now, first carry out layered treatment of the rootstock. When the rootstock grows to a certain height and thickness, grafting can be carried out. Choose suitable scions and graft in autumn. After grafting, pay attention to care, keep warm and moist, and remove rootstock sprouts to promote successful grafting. After survival, do not rush to remove the ties in winter. In winter, pay attention to freeze protection management.

2. Fertilizer and water management

After the fruit tree is grafted, in the management of the grafted seedlings, pay attention to watering and fertilizing. This is mainly to promote growth. Fertilize about once every one to two months, and each fertilization requires watering. But watering is not limited by fertilization. Water roughly when the soil is dry. Maintain 60% soil moisture. Waterlogging must not occur. The ditches in the orchard should be kept clear, and after heavy rain, drain water promptly. Also, in the later stage of growth, mainly apply phosphorus and potassium fertilizer, and in the early stage mainly apply nitrogen fertilizer. Use organic fertilizer and chemical fertilizer together.

3. Disease and pest control

Common diseases are anthracnose and ring rot. Use a 300-fold solution of Lianguoan, silicone, and a 600-fold solution of Wofengsu together for spraying twice to treat ring rot, then use a 60-fold solution of Kuifuling with added silicone for trunk spraying and brushing. Use a 600-fold solution of 80% Baoye complex-state mancozeb with a 2000-fold solution of 45% prochloraz microemulsion to treat anthracnose. For some common insects, aphids and mites, insecticidal lamps can be used.

4. Pruning methods

For seedling growth, mainly keep the trunk and main branches, then remove unwanted branches. Keep about 3 trunks and 5 main branches, and later branches can be kept level by level. Remove water sprouts, dense branches, diseased and pest-infested branches, and excess auxiliary nurturing branches. Young trees have not yet taken shape. They also have no aged branches, so the main goal is to help them take shape through reasonable pruning.

Dwarfing is a good way to cultivate fruit trees, and the same is true for apple trees. Cultivation requires attention to some basic management measures.
