Detailed Explanation of the Biological Characteristics and Growth Habits of Licorice
1. Biological characteristics (1) Flower size and seed characteristics. Due to different habitats, licorice naturally forms three ecotypes, namely sandy-land licorice, ridge-land licorice and floodplain licorice. The flowers of different licorice ecotypes are similar in size, but the seeds differ markedly in size, in the order floodplain licorice > ridge-land licorice > sandy-land licorice; the hard seed rate is ridge-land licorice > sandy-land licorice > floodplain licorice. Licorice grown from seed generally flowers and sets seed after 3 years. (2) Distribution characteristics of roots and rhizomes. Sandy-land licorice

Key technical points and precautions for transplanting licorice
Generally, it is done in late autumn or early spring. In late autumn, before the land freezes; in early spring, around Qingming Festival, and no later than mid-April. The transplanting field should be prepared on the basis of autumn plowing from the previous year by making beds (bed width depends on a row spacing of 50 cm and how many rows are planted in the bed), then applying fertilizer. Dig up the seedlings grown the previous year after the ground at the field corners thaws, remove the aboveground parts and the lower growing points, and set them aside for use. In the prepared field, open furrows at a row spacing of 50 cm, 12 cm deep, then place the seedlings flat at the bottom of the furrow, with the heads placed obliquely toward the inner slope, at a slope of 10 degrees. When placing the seedlings, 2 rows

How to grow licorice seedlings? Master these key seedling cultivation techniques
Choose sandy soil and loam with a low groundwater table and deep soil layer, but it must be irrigated land. When the ground surface temperature reaches 15°C, apply 3000 kg of farmyard manure per mu, plus 40 kg of American diammonium or nitrophosphate, then deep plow 40-50 cm. Deep plowing is essential (otherwise the seedlings grown will have short roots and many branches, mostly failing to meet the specified quality standards). Make a flat seedbed and water once, with the amount of water bringing the soil to the black moisture state (that is, when you grab a handful and throw it down, it does not crumble but holds together like a cake). After three to five days, shallow plow once more, then you can open furrows and sow. Follow the drilling method for seedling cultivation, with a row spacing of 2

Detailed Explanation of Key Techniques for Licorice Seedling Cultivation and Transplanting
The licorice seedling cultivation base requires good irrigation conditions, level plots, and fertile soil. There is no limit on plot size; seedlings can be grown in open fields or developed in courtyards. Sowing can be done anytime from April to August each year, with 10 kg of treated seeds sown per mu. Drill sowing is used, with a row spacing of 15 cm, and 120,000 to 150,000 seedlings are maintained per mu. Licorice sown in spring is transplanted in the spring of the following year, while licorice sown in summer and autumn is transplanted in the spring of the third year. The transplanting row spacing is 35 cm, the trench depth is 8 to 10 cm, and the plant spacing is 8 to 10 cm. The flat planting method is used, with

Cultivation Techniques and Field Management Methods for Licorice
Licorice is a perennial herbaceous plant of the Fabaceae family, and the medicinal parts are the roots and rhizomes. It contains 5-11% triterpenoid compounds, glycyrrhizin, followed by flavonoid compounds such as liquiritin, liquiritigenin, isoliquiritin, isoliquiritigenin, etc. It is neutral in nature and sweet in taste, harmonizes the middle and relieves urgency, moistens the lungs, detoxifies, and harmonizes various medicines, making it an indispensable herb in many traditional Chinese medicine prescriptions.

Symptoms and Control Methods of Licorice Root Rot
Latin scientific name: Rhizoctonia solani Kuhn. Damage symptoms: Infected plants develop yellowed, withered leaves; the stem base and main root all turn reddish-brown and dry-rotted, with longitudinal cracks or red streaks on them; lateral roots are rotted or very few; diseased plants are easily pulled out of the soil; the vascular bundles of the main root turn brown; when humidity is high, pink mold grows on the roots. Morphological characteristics of the pathogen: generally caused by nematodes and Pythium species. Classification: called Rhizoctonia solani, a fungus of the subphylum Deuteromycotina. Disease occurrence characteristics: Fusarium is a soil-inhabiting fungus, in the soil
