Introduction of sowing methods and common varieties of Luohan pine

Luohan pine alias Luohanshan, Taxodium, pine family, evergreen, vigorous and elegant, is a more valuable greening tree species. What is magical and interesting about Luohansong is that in the leaf axils of the female tree in summer, there will be seeds like little Luohan. The "bald" part of the seed is a lateral ovule, and the seed receptacle below looks like Luohan's body, and the slightly protruding place of the seed receptacle is very similar to Luohan's hands. After the seeds mature, the color of the seed receptacle will change from green to yellow, from yellow to red, and finally to purple-brown, like a Luohan in various cassock robes, hence the name "Luo Hansong".

The sowing method of Pinus elliottii: sowing after seed collection in August and sprouting after about 10 days; cutting: spring and autumn can be carried out, dormant branches are selected in spring, semi-woody twigs are selected in autumn, 12-15 cm, inserted into the seedbed of sand and soil in half, about 50-60 days to take root.

There are nearly 100 varieties of Luohan pine. At present, common varieties include Lanyu Luohan pine, Japanese Luohan pine, sparrow tongue Luohan pine, island Luohansong, Hainan Luohansong, Dali Luohan pine, short-leaf Luohansong, rice leaf Luohansong, long-leaf Luohan pine, big-leaf Luohan pine and so on.
