Chinese toon likes temperature and is suitable for cultivation in areas with an average annual temperature of 8-10 ℃. Its cold resistance increases with the increase of tree age. Young trees tend to wither in early spring in cold and dry areas.
The annual seedlings of direct seeding may be frozen at about - 10 ℃.
Like light, it's better to have more sunlight.
It is more resistant to humidity and grows in the fertile and humid sandy loam near the river, road or house. The suitable pH value of the soil is ph5.5-8.0, and its anti pollution ability is poor.
In spring, 10 cm ground temperature was sown at 5 ℃. The seed coat has a layer of wax, which is difficult to absorb water. Before sowing, it is soaked in warm water for 24 hours, then it is sprouted in warm place (or mixed with wet sand), and the radicle is exposed before sowing. In North China, wind barriers or soil can be built in winter. In the cold area, when the leaves of the seedlings stop growing, the seedlings will come out and live through the winter in the cellar.
About 10 days before sprouting in early spring, sprouting tillers were dug and planted. It can also cut the roots of one or two-year-old trees and bury them in the soil, and leave a strong bud when the height of seedlings is 10 cm.
The suitable harvest period is before the fruit turns brown and does not crack. However, it should be noted that the trees that pick buds every year have few or no flowers.
Apply organic fertilizer in the hole every spring, and cut dead branches after turning green. After harvesting, watering, pruning the new shoots of the year between June and July to promote the regeneration of lateral branches and increase the yield.
Watering and fertilizing in summer and autumn can restore the tree vigor and make the branches and buds full and plump, and reduce the frost damage. Water before winter.
Greenhouse cultivation of Chinese toon is a kind of artificial planting. In November, the two or three-year-old seedlings that have passed dormancy were planted in the temperature room. Under a certain temperature and humidity, the nutrients stored in the seedlings were used to extract the short branches, and the young leaves were taken for 35-40 days or once.
The seedlings should be abandoned when they are exhausted of nutrients, or 4-5 leaves should be left when they are collected, so as to gradually recover their vitality. They should be used again in summer, autumn and winter after cultivation.
