Description

Technical Field

[0001] The utility model relates to a potato sprout digging knife, belonging to the technical field of potato planting equipment. Background Art

[0002] Planting potatoes requires four steps. You need to select suitable soil for planting potatoes, then select seeds and use rooting powder to germinate them. After germination, they can be planted, and daily maintenance and fertilizer can be applied to promote growth. The second step is to process the seeds: after selecting the soil for planting, you need to process the seeds stored last year. Note that it is best to choose seeds with undamaged potato skins. After washing a potato, cut it into 4 pieces, and ensure that there is at least 1 small pit on each piece of potato. After dipping in rooting powder, put it in a humid and warm environment. After standing for seven days, the potato pieces will germinate and can be sown.
