Licorice cultivation and management techniques
Licorice is also known as sweet grass root, red licorice, and grass. It is a leguminous plant and is rooted with rhizomes. Licorice is a perennial herb with a height of 30-40 cm. The roots are thick, cylindrical, sweet-smelling, red-brown, stems upright, and the bottom slightly lignified. Leaves alternate, butterfly-shaped, pale purple. Seed flat round. Flowering from June to July, fruiting from July to September. Licorice has a sweet taste, clearing away heat and detoxifying the lungs, relieving cough, and reconciling the effects of various drugs. It is a brother of 100 herbs. All land can be planted except for the land where the depression and high groundwater level are not suitable for planting. First, cultivation techniques 1 Seed breeding. Sowing in early April. Since the licorice seed cortex is hard and thick, and the light permeability is poor, it is best to try to grind the seed coat before sowing, or soak it in warm water for 1 month after soaking with wet sand to accelerate seed germination. When planting, shallow grooves are set at a spacing of 30 cm, and the depth of the grooves is about 1.5 cm. The seeds are evenly spread into the ditch, covering about 1 cm of soil, and the amount of seed for every 667 m2 (1 mu) is 2-2.5 kg. 2 Rhizome reproduction. Rhizome reproduction and growth is fast. When digging licorice in spring and autumn, the crude roots should be used as medicine, and small rhizomes should be selected and cut into 12 to 15 cm segments with 2 to 3 buds each, with a spacing of 30 cm. Ditching, ditch depth 10 cm, according to the spacing of 15 cm in the rhizome will be placed in the ditch, and finally cover the soil leveling, suppression, watering. Second, field management Before and after the emergence of the soil to keep the soil moist, in order to facilitate the growth of seedlings after seedling emergence, drought should be timely watering. Seedlings grow when the seedlings grow 2-3 leaves, and the spacing between the shoots is 10-12 cm. Timely weeding, rhizomes appear on the ground after plant growth, and soil should be properly cultivated. Before freezing, 2000-2500 kg of fertilizer will be applied per 667 square meters. Food crops can be grown in order to make full use of the land. After the rhizomes of licorice are spread over the entire land, no special management is required.
