For this tall seedlings, transplanting, if the conventional vertical planting, there will be (a) bow waist phenomenon. So that the head of the seedlings in contact with or close to the ground, so that the tender tip of the ground by the steaming and sun and wilting, resulting in low survival rate; (B) due to the growth and development of tall seedlings slow, anti
