Platycladus orientalis seedlings leave the nursery for two years and are transplanted in the spring of the following year. Sometimes in order to cultivate green seedlings, it is necessary to transplant them 2-3 times to cultivate large seedlings with developed roots, strong growth and beautiful crown, and then plant them in the garden. According to local experience, the survival rate of transplantation in March-April in early spring is relatively high, generally reaching more than 95%.

The transplant density depends on the culture cycle. Seedling raising after transplanting 1 year, plant spacing10cm× 20cm; Cultivation for 2 years, row spacing of 20 cm ×40 cm; Cultivation for 3 years, row spacing of 30 cm× 40 cm; Cultivate large seedlings over 5 years old, with row spacing 1.5m× 2m. Generally, it takes many transplants to cultivate large seedlings, which is not only conducive to promoting the growth and development of seedling roots, but also to cultivate good crown and stem shapes and improve land utilization.

According to the size of seedlings, different transplanting methods are adopted, such as narrow slot transplanting, ditching transplanting and digging transplanting.

The management of seedlings after transplanting is mainly to irrigate them in time and thoroughly every time. When the soil moisture is suitable, timely adopt tending measures such as intertillage, weeding and topdressing. Except for shaping and pruning according to the requirements of landscaping, other measures are basically the same as those of general conifer seedling raising.

Planned cultivation 1 year, row spacing of transplanted plants 10× 20cm, row spacing of biennial plants 20×40cm；; The 3-year plant spacing is 30×40 cm. If you want to plant hedgerows, it is advisable to plant two to three-year-old seedlings, double row planting or single row planting, and planting should not be too deep. It is advisable to bury the hedge in the soil to a height about 1 cm higher than the original scar. Irrigation should be done immediately after planting, and inspection should be made in time. If there is lodging and exposed roots, it is necessary to strengthen the body and add soil. If possible, it is best to wash the transplanted seedlings frequently, which can improve the survival rate. In addition, seedlings are susceptible to physiological drought in early spring, so they need to be irrigated with frozen water, and irrigation should be strengthened in early spring. According to the investigation, irrigation in late February in this area can largely prevent seedlings from drying up and avoid the cold period in late spring, so that if properly managed, the hedge will basically take shape after 3-4 years.
