The propagation method is to propagate with tubers. After harvesting tubers in autumn and winter, choose 20-25g tubers for sowing, or store them in sand for seed preparation. You can also dig out tubers of the right size and sow them after the soil thaws in spring. ?

Sowing takes place in spring. Hole sowing or furrow sowing. The plant spacing is 50 square centimeters.

Plant holes, dig loose soil, and sow after applying base fertilizer, but the base fertilizer should not be too much. The sowing depth is about 10 cm. After sowing, cover the soil and level the pit. ?

Seedling emergence is about 1 month after field management sowing. Appropriate topdressing and watering after emergence. Then intertillage weeds and cultivate the soil into low ridges. When it is not too dry, you don't need to water it again, and then water it until the tuber expands, in line with the principle of "seeing dry and seeing wet". If the stems and leaves grow too luxuriantly, the tops should be picked to promote tuber expansion. Jerusalem artichoke is rarely damaged by pests and diseases, so there is no need to use pesticides. Aphids may appear in extreme drought and can be eliminated by spraying water. ?

Harvest after autumn frost. After harvesting and digging, it is cleaned up and taken out of the soil for marketing. If it is planted in idle land, if it is necessary to continue planting, small tubers can be selected and buried in the soil during excavation, and interplanting and replanting should be done in time after emergence in the next year.
