Breeding method

I. Tubers

After harvesting the tuber of Arisaema orientalis in September/Kloc-October/October, select small and medium-sized tubers that are robust, intact and free from pests and diseases, dry them in the air and store them in the cellar for seed use. The excavation depth is about 1.5 m, and the size depends on the number of seed tubers. It is appropriate to keep the temperature in the cellar at about 5- 10℃. Below 5℃, seed tubers are vulnerable to freezing injury; Above 10℃, it is easy to germinate early. Generally, it is taken out and planted in the spring of the following year, and it can also be planted in autumn before freezing.

Spring planting is carried out from late March to early April, and holes are dug on the whole border surface according to the row spacing of 20-25cm and the plant spacing of14-16cm, and the hole depth is 4-6cm. Put it into seed planting, with bud head up, per hole 1 block. After planting, cover soil mixed fertilizer and fine soil, and if it is watered in drought, it will be permeable 1 time. It can sprout in about half a month. If large tubers are used as seeds, two or more pieces can be cut longitudinally, as long as each piece has 1 strong bud head, it can be used as seeds. But after cutting, the wound should be smeared with plant ash in time to avoid decay.

When the tubers are cut and planted, the small tubers should be covered with shallow soil and the large tubers should be deep. Generally, about 675 kilograms of large tubers and 300 kilograms of small tubers need to be planted per hectare.
