The suitable temperature for growth is 1525 ℃, and it can withstand low temperature of-8 ℃ in winter. The soil is a deep, fertile and well-drained sandy loam, but also resistant to acid and calcareous soil.

Propagation method of Acer truncatum

Ⅵ sowing: collecting seeds in October, slightly drying off wings, sowing in autumn or wet sand stratification, sowing in spring and February. Cover soil 1 cm and sprout 30-40 days after sowing. Seedlings should be shaded and moisturized. The height of the seedlings in that year can reach 30cm to 40cm.

Ⅶ grafting: mainly used for cultivated varieties, rootstock for 2-3-year-old Acer truncatum. Branch grafting was carried out in March in spring, cutting or ventral grafting was carried out when the leaf buds of rootstocks were enlarged, and bud grafting was carried out in August in summer, mainly with single bud ventral grafting, and the survival rate was high. It would have been a seedling in that year.

Ⅷ striping: carried out in October, using high-altitude crimping method. Circular peeling was carried out at 20-25 cm from the top of the branch and wrapped with rotten leaf soil and film. The seedlings will grow in the following spring.

Acer truncatum should be planted in fertile, semi-shady and humid sites after defoliation in autumn and winter or before sprouting in spring. Pot planting should be carried out after the leaves are removed in late August, put in a semi-shady and moist place, and fertilize 1-2 times to promote luxuriant branches and leaves. After frost, the leaves turn yellow and red, and the leaves are maintained in the room, and the shedding of the leaves is delayed, which can prolong the viewing period.

Pest control

In the cultivation of Acer chinensis, anthracnose, leaf spot and black spot are often harmed, and usually can be sprayed with Bordeaux solution or 70% mancozeb wettable powder 600 times. Insect pests include diamondback moth, large coir moth, aphids and longicorn beetles, which can be sprayed with 1500 times of fenitrothion.
