1. What kinds of yam are there?
There are many varieties of yam, including water yam, iron stick yam, small white mouth yam, ox leg yam, mashu yam, fine wool yam, ganoderma lucidum yam and so on. Among them, the water content of water yam is very high, and it will be broken when touched lightly. Iron stick yam is a fine yam with delicate and firm meat. White-billed yam is known as the best yam, which brings the beauty, taste and nutrition of yam to the extreme. The appearance of Niutui Yam is very firm, and the taste is also very good.
Ridge planting: Ridge height is about 30cm, bottom surface is 80cm and top surface is 40cm. Plant on both sides of the ridge according to the row spacing of 30 cm and the plant spacing of 20 cm. Open a hole on the ridge surface, and the depth of the hole should be straight. If the roots of the seedlings are too long, cut off the lower part and keep the seeds with the length of 10- 15cm. Stand the seedlings upright in the hole, then soil them and compact them.
Planting yam depends on the scale. Generally, it is mostly mechanical planting. If there is little personal cultivation, I can recommend using rice bags. Just dig a hole the size of a pocket, then put soil in the pocket, put yam seeds in the pocket, and bury the pocket in the dug hole and then bury it back. The purpose of this is to prevent yam from growing in deep soil and being difficult to dig. If you do this, yam
In rural areas, it is generally to find a place with soft soil, so that it is easy to dig. If the soil is soft, yam will grow very big. If the soil is hard, you can also dig holes to make the soil less hard. There is also a better planting method, that is, planting horizontally and vertically with plastic molds, so that the harvest is easier to dig and the damage is reduced.
