Now its breeding and cultivation points are as follows. 1 Growth Habits: Toon is a temperate and subtropical tree species, hi light, hi fertilizer, in an average annual temperature of 13 ~ 20 ℃, the annual rainfall of 500 ~ 1200mm area grow well. Most suitable for deep soil, well drained neutral alluvial sand growth, in the low water, saline-alkali land, arid ridge land, poor growth and cultivation of sand. 2 nursery: Toona root tiller bud strong, can be inserted or seedling breeding seasons. (1) root nursery.
