In 1973, I set up a mining garden to breed No. 1-13 of M series (No.12) scion. 74 years sowing the chestnut, 750 years of transplanting establishment of breeding dwarfing middle seedling breeding nursery. In the spring of 1977, twenty-four composite seedlings of M type and 12 types of intermediate grafting grafted seedlings such as Golden Crown and Red Star were planted in Yuzhang Zhang Hu Point and the place for M-type dwarfing interstock cultivation. Its purpose is to validate and explore the apple dwarfing intermediate anvil cultivation and management techniques and selection of good anvil anvil combination.
