Some pines bear fruit early, a little in 5-6 years, and some bear fruit late, which may take 80- 140 years in natural environment. Artificial cultivation bears fruit early, and most pine trees bear fruit at intervals, and generally harvest once every 2-3 years.

The fruit of a pine tree is actually a pine cone, also called a pine cone. From the outside, it looks like a pagoda with an oval shape and a fish-scale surface. Inside the pine cone are pine nuts, which are the seeds of pine trees.
