Grasping seedling management before transplanting seedlings is the basis for ensuring early post-transplantation of herbs. The following three things must be done during this period:

Apply a "send marriage fat"

In the mid-care period of medicinal herbs, the measures for controlling fertilizers and water are generally adopted to carry out seedlings, with little or no nitrogen fertilizer, in order to increase the carbon content in the body, which is conducive to the smooth transition from the hairy stage to the full stage of strong seedlings, and to achieve the cultivation of strong seedlings. purpose. However, the rooting power of the medicinal seedlings is closely related to the nitrogen level in the body. The low nitrogen content in the seedlings of the seedlings has weak rooting power. Therefore, herbicide seedlings must be topdressed before the emergence of a "send marriage fat" in order to increase the nitrogen content of the drug seedlings, enhance hair root. In addition, due to the short interval between application and transplanting, the transplanting seedlings can be maintained by relying on the accumulation of their own nutrients after transplanting to Daejeon, establishing a new root system and quickly recovering their growth. The adaptability is strong. Practice has proved that the use of "fertility" of medicinal herbs strong seedlings, live trees after returning green fast, leaves withered off less. "Feeding fertilizer" is generally applied 5 to 7 days prior to transplanting. It is appropriate to apply 5 to 8 kg of urea per acre seedbed. The application method is generally applied by spreading or dissolving in water to dilute and then pouring, according to the humidity in the field. And set.

Play a "preservation drug"

Before the transplanting, the medicinal herbs are used to fight drugs on the seedbed before they are transplanted. On the one hand, the pathogens and pests attached to the seedlings can be eliminated, the seedlings can be protected from pests and diseases, and the spread to the field can be prevented; on the other hand, the transplanting with the medicine can also be carried out. It can inhibit the pests and diseases that remain in Daejeon. Therefore, it is a measure to prevent and control diseases and insect pests that saves labor, saves money, and saves money. "Preservation of the drug" is usually sprayed 1 to 2 days before transplanting. The medicine can be selected according to the occurrence of the disease at the seedling stage of the medicine.

Pour water once

Herbs often encounter dry weather during the transplanting stage, and should be poured once before rising. In this way, one is that the soil is moist and it is easy to raise seedlings; the second is to reduce the number of planting wounds and to increase the number of mulching roots, so that after the drug seedlings are planted in the field, the new roots will be quickly grown, the early living trees will be returned, and the green will be returned; With high water volume and enhanced drought resistance, it is not easy to lose water and dry up after planting in the field. The phenomenon of dead seedlings occurs, with strong roots and rapid growth. "Getting up" should be watered the day before the seedlings are raised. It is easy to raise the soil until the soil is wet and it is easy to raise seedlings. It is also possible to start seedlings in the morning on the second day and transplant them in the afternoon. The watering time should not be too early, otherwise the medicine seedlings will grow too tender due to sufficient water, the stems and leaves will be brittle, and the seedlings will easily damage the leaves or break off the seedlings.
