There are many advantages, so now it is generally dwarf cultivation. How to cultivate dwarf apple saplings, what to pay attention to, now together to understand the specific cultivation methods.

1, seedling method

The rootstock is cultivated now, and the rootstock is processed hierarchically first. When the rootstock grows to a certain height and thickness, grafting can be carried out. Select the right scion and graft in autumn. After grafting, attention should be paid to maintenance, heat preservation, moisture preservation, and removal of rootstock sprouts to promote grafting survival. After survival, do not rush to dismantle the tie into winter. Winter should pay attention to antifreeze management.

2. Fertilizer and water management

After fruit tree grafting, the management of grafted seedlings, pay attention to watering, fertilization work, mainly to promote growth, about once a month to two months fertilization, each fertilization needs watering. But watering is not limited by fertilization. Perhaps the soil needs watering when it is dry. Maintain 60% soil moisture. Do not accumulate water, orchard ditches should be dredged, heavy rain, timely drainage.

Organic fertilizer and chemical fertilizer are used together.

3. Disease and pest control

Common diseases are anthracnose and ring disease. Spray 300 times solution of Liangguo 'an, organic silicon and 600 times solution of Wofengsu twice to treat ring disease, and then spray and brush trunk with 60 times solution of Kuihuiling and organic silicon. Anthracnose was treated with 80% mancozeb complex 600 times solution and 45% prochloraz microemulsion 2000 times solution. Some common insects, aphids, mites, you can use insecticidal lamps.

4. pruning method

Seedlings grow, mainly leaving trunk, main branches, and then remove unwanted branches, leaving about 3 trunks, 5 main branches, and then can leave branches step by step.
