First, according to local conditions, a high standard of building 1. According to the apricot hi light, drought, barren, waterlogging, flowering susceptible to the characteristics of late frost, planting should be selected leeward, sunny and well drained areas, should not use low-lying cold Air should be deposited in the place of planting, species selection should pay attention to varieties of late flowers, the appropriate choice of configuration pollination tree, ensure fruit, planting density is generally 4 to 5 m × 5 ~ 6 m, infertile thin planting, fertile land. Planting in the tree within the scope of coverage of plastic film. 2. Choose strong seedlings, carefully planted. As far as possible the local (or northerly) strong seedling without mechanical damage is selected. The standard of strong seedling is that the root system is developed, complete, without root nodules, with more than 4 roots and more fibrous roots; the height above 80 cm in height and 10 cm above the grafting Straight
