The author compared and tested under the same conditions, the dioscorea nipponica planting can increase the yield by more than 1 time than the normal planting. The seedlings that were planted in advance were slower than those grown in the saplings. It took about 7 days to grow new shoots among the leaves and leaves, and then slowly formed the main stem. Because the direction of the water and organic nutrients absorbed by the roots of the transporting tissue in the stem is reversed, the transport speed of the roots is slowed down, so that a large amount of organic nutrients are accumulated in the roots, so that the main stem on the ground grows slowly, which is beneficial to the expansion of the potato wedges.
