1. Reed head: The section with buds at the upper end of yam root tuber is called reed head, which has strong reproductive capacity.Generally, when digging out in winter, select relatively strong roots without pests and diseases, and cut off other reed heads, the length of which is between 15 and 20 centimeters.The cut reed head should be dried for 4-6 days, and after the section shrinks and heals, it should be stored in a ventilated place or sand, and the temperature should be kept at about 5 C.Wait until the next spring, take out and plant.Because the reed head is easy to degrade after being used for many years, it should be renewed every 2-3 years.
2. Lingyuzi: Lingyuzi is the bud of yam.It mainly grows on stems and tendrils, mostly cylindrical.When harvesting, shake them off and collect them.The seeds with full and large grains are selected.It is usually stored in wooden barrels and sowed in the next spring.The sowing time is mostly in March and April, deep tillage and fertilization are carried out before sowing, then the surplus seeds are planted and covered with fire ash soil, and the seedlings can emerge in 15-20 days after sowing.
3. Rhizome: The propagation method of rhizome is similar to that of reed head.Cut the harvested yam into small sections of 8-10 cm, apply plant ash on the incision, and put it in a ventilated place to dry for 3-5 days, until the wound heals, you can plant.It should be noted that because the part it eats is the rhizome, it is rarely used for reproduction.
When planting yams at home, first of all, we should choose a good flowerpot, in order to ensure that the soil layer is deep and convenient for the growth of rhizomes, the flowerpot should have enough height.Fill a certain amount of sandy soil in the pot, cut the yam into small sections, treat the wound with plant ash, and plant it inside.After planting, we should irrigate enough water and provide appropriate light.
