Evergreen trees can grow to 40 meters high, and DBH is 1 meter. The leaves are scaly, triangular, 3-6 cm long, 5- 10 mm wide at the bottom and sharp at the edge. Leaves can grow for 10- 15 years, covering most trees except trunk and old branches.
Dioecious, male and female cones are on different trees. The male cones (pollen) are oval, initially 6 cm long, with a pollen release time of 10- 18 cm and a width of15-25mm. Female cones (seeds) mature in autumn after fertilization 18 months, and are spherical, with a diameter of 18-25 cm, containing 100- 150 seeds and a length of about 5 cm. When the cones are ripe, they are broken and released.
Growth situation
Brazil pine nuts, flowering for 5 weeks, fruiting in September -65438+ 10. Pine nuts fall one after another after the pinecones mature and crack, and the picking time is generally from mid-September to mid-June, 65438+ 10. A pine cone takes about three years from flowering to maturity, and its yield is extremely limited, so it is extremely precious. It takes a month for pine nuts to mature, pick, transport and process. It will be sold to China in June165438+1October.
