Annual apple seedlings, after planting, are cut off according to the specified height and called dry. The height of young trees depends on topography, soil, climate and variety.
When fixing the valve stem, leave a plastic belt. If the drying height is 50-60 cm, plus the height of 20 cm plastic belt, it is necessary to cut and dry at the height of 70-80 cm. There should be 8- 10 full buds in the plastic belt.
The fixed stem is divided into two times, which is called secondary fixed stem. After planting, the stem should be fixed once, and the cutting position should be higher than the predetermined position10 cm; When 3-4 new buds grow from the top of the branch, cut off the sprouting part (10 cm). In this way, the top advantage is destroyed, and the lower buds can germinate in large numbers, usually 6-8 branches can occur, and it is easy to select 3 main branches in one year. Using the method of secondary drying, the soil should be fertile, the management conditions should be good, the root system of seedlings should be developed, and the number of full buds should be more, so that the effect is remarkable. Otherwise, the purpose of promoting multi-branches cannot be achieved. Even if several branches can be added, the growth is poor, the utilization rate is low, and good main branches cannot be selected.
