Transplanting time should be selected from "heavy snow" to "winter solstice", planting on the same day, planting control plant spacing 18 cm ×15 cm or 21 cm ×18 cm. In high temperature areas should not be planted too dense, so as not to cause serious diseases and insect pests, before planting to apply sufficient base fertilizer, mainly decomposed farm manure, fertilizer mainly phosphate fertilizer, not more nitrogen fertilizer, so as not to cause seedling root rot.
