Value and reproduction of Platanus acerifolia
Platanus acerifolia is usually propagated by sowing, cutting and rooting. Harvest the fruits when they are ripe in autumn, and sow them in autumn of the same year after drying and threshing, or store them in dry or sand until spring sowing in the next year. The row spacing of drilling is 25 cm, the thickness of covering soil is about 15 cm, and the sowing amount per mu is about 15 kg. The seeds germinate more neatly in sand storage; Dry-stored seeds often germinate unevenly, so it is best to soak them in warm water to accelerate germination before sowing. The height of 1 year-old seedlings can reach more than 50 cm, and 3-year-old seedlings can be planted in the garden in the following spring.
seed treatment
Soak tung oil seeds in 5% carbendazim solution for 24-36 hours, take them out and mix them with sieved wet river sand, with the seed: river sand = 1: 3. Choose a place with high and dry terrain, sunny leeward and underground water level below 1.5 meters, and dig a pit with vertical walls. The size of the pit depends on the number of seeds. Add 5cm of river sand to the bottom of the germination pit, then place an aerator (tie 4-6 corn stalks), then put the mixture of seeds and river sand into it, cover it with 5cm of river sand, and finally cover it with 5cm of loess. Under normal circumstances, seeds can germinate in 30 to 40 days.
Platanus acerifolia is a common street tree and landscaping ornamental tree. It is a beautiful ornamental plant, dotted in gardens and houses, and also planted as a street tree.

Indus wood is light and soft, which is a good material for making wooden boxes and musical instruments. When the seeds are fried, they can be eaten or pressed with oil. The oil is non-drying oil. Generally, it can be dried in the sun to dry the seeds, boiled in water and taken orally, which has a good detumescence effect. The fiber of bark is white and can be used for papermaking and rope weaving. Wood shavings can leach out mucus, which is called wood shavings moistening hair. As a soil insecticide, leaves can kill aphids and adapt to gases such as sulfur dioxide and chlorine.
