How to do licorice seedling raising and transplanting? Detailed explanation of the latest technical tutorial
Licorice is a very popular Chinese herbal medicine and a perennial herbaceous plant. The main medicinal part is the rhizome, which has various effects such as resolving phlegm and detoxifying, clearing heat and relieving cough. Because of the increase in market demand, the planting area of licorice is now constantly expanding. Licorice is mainly planted by seedling raising and transplanting, so today the editor brings you the seedling raising and transplanting techniques for licorice. Let's take a look below!
1. Land selection
Licorice is a deep-rooted plant, so soil selection is very important. First, we should choose soil with sufficient fertility, soft texture and normal drainage and irrigation. Then apply an appropriate amount of farmyard manure per mu, then carry out ridging and bed making, compact the soil, and deep plow about 35 cm to prepare for sowing. Before sowing, while preparing the land, we should also disinfect the soil to eliminate pathogens and pests in the soil. This prevents licorice from being harmed by pests and diseases after sowing, which would affect germination and seedling emergence rate.
2. Sowing
Licorice can be sown in all seasons except winter. Spring sowing is generally after Qingming Festival, summer sowing is after Lixia, and autumn sowing is before the soil freezes. First, we should open a furrow of about 20 cm on the ridge surface, then level it with a plow, and carry out sterilization and disinfection of the seeds. After sowing, cover with an appropriate amount of soil, then compact. The sowing rate per mu is about 6-7 kg. After sowing, if the soil conditions are good, full seedlings can be achieved in about 10 days. To avoid rampant weeds, spray an appropriate amount of herbicide for weed control before sowing, and sow about one week after spraying.
3. Management
After the seedlings successfully break through the soil, we should often observe the condition of the seedlings to see whether there is any dead seedling phenomenon. If there is, pay attention to spraying agents such as thiophanate-methyl, dissolve them in water, and spray onto the leaves to avoid seedling death. If there is a phenomenon of missing seedlings, then promptly fill the gaps to ensure the full seedling rate. When the seedlings grow 5 true leaves, apply a topdressing of urea once, about 10 kg per mu. Then also pay attention to doing a good job of weed control to avoid weeds competing with licorice seedlings for growth, and finally strengthen the prevention and control of pests and diseases.
4. Transplanting
When transplanting, retain the horizontal diameter of the licorice root and reed head at about 5 cm, and follow the principle of digging and planting at the same time. Then dig a furrow about 10 cm deep and plant the licorice seedlings appropriately into the furrow. Control the plant and row spacing well, keeping it at about 10 cm. After planting, cover with soil and water, and compact the soil appropriately to improve the soil's moisture conservation capacity. Generally, about 20,000 plants are planted per mu, and then before the soil freezes, water once to settle the roots. Finally, do a good job of topdressing, pesticide application and other tasks to ensure the healthy growth of licorice seedlings.
The above is a brief introduction to licorice seedling raising and transplanting techniques. The seedling raising work of licorice is relatively important and affects the yield and quality of licorice, so everyone must pay more attention. That is all for today's introduction.
