Yacon stems are erect, round, purplish red, clustered and 2 to 3 meters high. The leaves are opposite, broadly heart-shaped, and the surface is slightly thicker. Leaves are 25 to 30 cm long, width 15 to 20 cm, and petiole length is 7 to 12 cm. The head is clustered at the top of the stem, with 3 to 6 disks, tongue-shaped flowers and yellow. Achene fibrous roots, distributed in the plough layer 5-30 cm. The root tuber is spindle-shaped. Tubers are attached to the rhizomes irregularly, and the epidermis is pink.
growing environment
Yacon is particularly resistant to strong light, likes medium and low temperatures and avoids waterlogging and drought. It can grow in areas where the annual average temperature is lower than 65438 08℃. The optimum growth temperature is 5 ~ 25℃, the optimum temperature is 10 ~ 20℃, and the relative humidity is 80 ~ 85%. Tubers (i.e. seed potatoes) germinate about 2 months after sowing. When the temperature is higher than 16℃, the root tuber begins to swell, reaching the peak at 20-25℃. Not cold-resistant, the stem on the ground will dry up and die when it meets frost, and the root is not easy to freeze below 0℃. Therefore, it is suitable for growing at the low latitude of 1000 meters above sea level, and it is foggy all the year round. ?
