Detailed Explanation of the Key Cultivation Techniques for Dwarf Apple Trees

Dwarf apple tree cultivation is the mainstream direction of the modern apple industry, and many fruit growers have begun to cultivate dwarf apple trees. What are the cultivation techniques for dwarf apple trees? The main techniques are introduced as follows:

1. Raising seedlings: Most fruit growers use grafting techniques to propagate fruit seedlings. When grafting, fruit growers must ensure the quality of the rootstock. To cultivate rootstock seedlings, the stratification treatment must first be carried out, and attention must also be paid during the management, grafting and rootstock seedling propagation stages. When the seedlings grow to a certain height, fertilize and irrigate the fruit trees, and during this process strictly control the amounts of fertilizer and water. After autumn begins, start autumn grafting. During autumn grafting, pay attention to the amount of scion used, and collect it before Awakening of Insects.

2. Water and fertilizer management: During the planting process, ensure that watering, fertilizing and drainage for the fruit seedlings are carried out in an orderly manner. In the middle and late stages of fruit tree growth, apply phosphorus and potassium fertilizers, while reducing nitrogen fertilizer. After the fruit is harvested, apply organic fertilizer mixed with chemical fertilizer to increase soil fertility.

3. Pest and disease control: The main pests and diseases of apple trees include ring rot, anthracnose, mites and aphids. To control insect pests, insect-killing lamps can be hung in the orchard. To control ring rot, 50% carbendazim wettable powder at 50 times dilution and 5% Ansoljunduqing at 50 times dilution can be used, or Pingfu Sukeling can be applied directly to the disease galls on the fruit trees. To control anthracnose, 75% Dakening, 10% Shigao water-dispersible granules and other medicines can be used.

4. Pruning: During the growth period of apple trees, fruit growers need to prune them according to the growth conditions of the fruit trees. If an apple tree has too many branches and leaves, its growth rate will be affected, so prune branches and thin leaves appropriately, leaving the upward-growing branches of the fruit tree.

The above are the cultivation techniques for dwarf apple trees. The cultivation of dwarf apple trees is similar to that of ordinary apple trees, and planting and management are also relatively convenient.
