1. Selection of potting containers. The various lines of the apple tree are relatively developed and will bloom and bear fruit. Therefore, a relatively large container should be selected to provide sufficient nutrients for plant growth and sufficient space for root growth. It is best to choose a 50cm X 50cm non-woven container bag.

2. Cultivation soil preparation. The basin soil is preferably loose, has good drainage, strong aeration, and high humus content. The proportion of nutrient soil is: 60% field soil, 20% leaf humus soil, 20% farmyard manure, 1% carbendazim, and methylthiobacterium. Mix 1% of Lingxin and 2% of compound fertilizer and stir evenly.

3. Cultivation of potted stock seedlings. Now trim the roots of the selected stock seedlings and dip them in the pulp, and then plant them in the selected container bag. The root system is required to stretch, and the depth should be 3~5cm above the original soil mark and flush with the mouth of the container. Shake the container while drawing. It is conducive to close contact with the soil and prevents the seedlings from tilting after irrigation. Finally, plant in the field according to the spacing of 1mX1m, 2 rows of majestic stubble, and the ridge spacing of 1.5M. After planting, irrigate with water, cover with a layer of dry soil after water seepage, and then tree tray When covering with film, set the stem height to the target tree shape. If the target tree shape is open or V-shaped, set the stem height to 20CM~30cm and the main trunk shape to 30~50cm. In the future, branches will be selected according to the target tree shape. 7~ For bud grafting in August, the grafting method is to cut a "T"-shaped opening at the grafting point, deep into the xylem, and then use the tip of a knife to peel off the bark of the rootstock, embed the shield-shaped grafting buds in advance, so that the cambium layer is aligned, and use a 1cm wide The width of the plastic bag should be 1cm above and below the incision.

4. Potted plants and daily management. In order to facilitate management, pot the seedlings after 2 years of cultivation. After the leaves fall in winter or before budding in spring, choose a pot of the same size as the container. Move the seedlings to be potted into the pot together with the container, and water them thoroughly at the same time. Use water to cultivate the fruiting branches. The method of growing first and then shrinking, in order to ensure that it bears fruit year after year, uses the "three sets of branches" method to select the remaining branches, and cut off diseased and insect-infested branches, overlapping branches, cross branches and competing branches. When fruiting, the amount of fruit left should be appropriate to ensure vigorous tree body and fruit quality.

5. Prevention and control of potted plant diseases and insect pests. It is best to choose low-residue pesticides. You can also use pepper water, garlic water, alkaline water, tobacco leaf water, water stickers, fire extinguishers and other methods to prevent pests and diseases.
