The latest course on techniques and methods of raising seedlings and transplanting licorice

Licorice is a very popular Chinese herbal medicine and a perennial herb. The main part of medicine is the rhizome, which has various effects such as expectoration and detoxification, clearing heat and relieving cough. Due to the increasing market demand, the planting area of licorice is constantly expanding. The planting mode of licorice is mainly seedling transplanting, so the editor brings you the seedling transplanting technology of licorice today, let's take a look!

1. Select the place

Licorice is a deep-rooted plant, so the selection of soil is very important. First of all, we should choose soil with sufficient fertility, soft soil and normal drainage and irrigation. Then apply an appropriate amount of farm manure per mu of soil, and then ridging to do border work, the soil will be suppressed, turned about 35 cm deep, ready to sow. Before sowing, we not only carry out soil preparation, but also disinfect the soil to eliminate germs and pests in the soil. Prevent licorice from being harmed by diseases and insect pests after sowing, affecting the rate of germination and emergence.

2. Sowing seeds

Licorice can be sown except in winter. The sowing time is generally after Ching Ming Festival in spring, after the Beginning of Summer in summer and before freezing in autumn. First of all, we should make a groove of about 20cm on the ridge, then plough it flat, and sterilize the seeds. Cover the soil properly after sowing, and then suppress it. The sowing rate per mu is about 6-7kg. After sowing, if the soil condition is good, the whole seedling can be completed in about 10 days. In order to avoid weeds, herbicides should be sprayed properly before sowing, and then sow about a week after spraying.

3. Management

After the seedlings have successfully broken the soil, we should often observe the situation of the seedlings to see if there is a phenomenon of dead seedlings. If there is, then pay attention to spraying methyl topiramate and other agents, mixed with water to dissolve, spray on the leaves, to avoid seedling death. If there is a lack of seedlings, then it is necessary to replenish the seedlings in time to ensure the whole seedling rate. When the seedlings grow 5 true leaves, urea should be applied once, about 10kg per mu. Then we should also pay attention to weeding, avoid weeds grabbing the growth of licorice seedlings, and finally strengthen the prevention and control of diseases and insect pests.

4. Transplanting

When transplanting, it is necessary to keep the horizontal meridian of licorice root Reed head about 5cm, according to the principle of digging and planting. Then dig a ditch about 10cm deep and plant licorice seedlings into the ditch appropriately. Control the row spacing and keep it around 10cm. After planting, it is necessary to cover the soil and water, properly suppress the soil, and improve the soil moisture conservation capacity. Generally, about 20,000 plants are planted per mu, and then the soil should be watered once before the soil is frozen. Finally, it is necessary to do a good job of topdressing and pesticides to ensure the healthy growth of licorice seedlings.

The above is a brief introduction to the transplanting techniques of licorice seedlings. The seedling raising of licorice is more important, which affects the yield and quality of licorice, so we must pay more attention to it. That's all for today's introduction.
