1, base selection
Wild cherry root system is the preferred root system, because of its resistance to underground insect bites, strong cold resistance, strong resistance to drought, strong acid and alkali resistance, resistance to fertilizer and root injury, resistance to fertilizer, good wind resistance, developed roots, Long age and other advantages. Wild apricots and wild peach roots can also be used. These two root systems are poorly tolerant and only suitable for cultivation. The above three root systems are superior to Shandong Cao Ying, Da Qing Ye, Benxi Shan Ying, and Court. Solved the problem of serious dead trees caused by poor roots.
2, grafted seedlings
In the spring, seeds of cherries (also known as wild cherries) were sown. From August to September of that year, with hairy cherries as the base anvil, the same year as the base anvil, the plums were grafted on the base anvil and 2-4 centimeters from the ground. The best effect is to use D-type buds. Every 6 to 7 months, from the third to the fourth month of the second year, an anvil is cut at 0.5 to 1 cm at the upper end of the junction between the buds and the base, and the buds are removed. After that, the new root anvil is erased at any time. Meng sprout. From June to July of that year, with the buds of the plums as the middle anvil, the cherry scion of the same age as the middle anvil was grafted onto the middle anvil by means of budding, and the buds should be separated from the middle anvil and the anvil joint. 2 to 3 centimeters at the top, and retain the length of the anvil, cut off the rest. When the cherry shoots grow to 14 to 16 cm, the anvil is cut at an anvil 0.5 to 1.5 cm above the junction of the cherry sprouts and the anvil, and the buds are removed. At this point, the grafting of the entire dwarf cherry seedlings was completed, and fertilization and pesticide application were performed until the nursery was released in early November.
