Biological characteristics of Angelica sinensis (3)
The main results are as follows: (1) bolting and flowering Angelica sinensis is an one-time flowering plant, and under normal cultivation conditions, the third year enters the bolting and flowering stage, and about half a month after the plant turns green, the growth point begins to change from the vegetative growth state to the reproductive growth state, forming the reproductive growth point. its tip gradually produces some protuberances, namely inflorescence primordia. With the elongation and growth of inflorescence primordia, each primordium begins to widen and produce several small protuberances, that is, small sequence primordia, which form the embryonic form of compound umbels. At the same time, the basal stem expands and grows, forming internodes and forming

Biological characteristics of Angelica sinensis (2)
The main results are as follows: (1) the root growth of Angelica sinensis spans three years from sowing to physiological maturity, and the whole growth period is more than 500 days. After the seed germination, the radicle lengthens rapidly, bends downward and grows into the soil. When the main radicle extends to 3 cm, the primary lateral root begins to form, and then the secondary lateral root appears on the primary lateral root. The main root continues to thicken and elongate, and gradually becomes fleshy, forming a typical fleshy straight root with a length of 20 cm and a diameter of 0.3 cm. April of the following year

Seed retention of Angelica sinensis
Seedling transplanting requires the use of moderately mature seeds from the third year of flowering. A plant, in addition to the main bud, there are many lateral buds. Both main bud and lateral bud can sprout, flower and bear fruit. Flowers and seeds can also grow between the axils of the main stem. Due to the different growth time of each flower, the flowering time and seed maturity are first and then. Therefore, when collecting seeds, we must often observe the field. Looking down from the top of the flower stem, see the first ear is pink, the second ear is pale red, and the third ear is pale yellow, that is, it needs to be harvested (generally in mid-August). overripe seed

Processing method of Angelica sinensis
After harvest, shake the soil, pick out the rotten roots, remove the residual petiole, wait for the water to evaporate slightly, tie it into a flat handle weighing 0.5 kilogram, and put it in the smoke shed. A 130 cm high scaffolding is built in the smoke shed, which is covered with bamboo strips, and Angelica sinensis is laid flat and upright alternately, with a thickness of 30 cm to 50 cm. Using bean straw, wet poplar and willow as fuel, spray water to make it smoke, no open fire, smoke color, until the skin of Angelica is crimson, change to coal fire or firewood (grass) fire for about 10 days, overturn

Breeding techniques of Angelica sinensis
Angelica sinensis is propagated with seeds, generally using the method of raising seedlings and transplanting, or direct seeding. 1. Seedling transplanting (1) selected seeds: the yield of Angelica sinensis seeds is 14.6 kg higher than that of unselected seeds per mu. The main method of selection is ear selection. During the harvest of Angelica sinensis, when the seed epidermis is blue or pink and the scape is drooping, the ears with the characteristics of this variety, good growth, no diseases and insect pests and high maturity are selected, cut off together with the scape, dried in a ventilated and dry place, threshed and stored. Due to the inconsistent maturity of Angelica sinensis seeds, the harvest

Breeding methods of Angelica sinensis
Propagate with seeds, raise seedlings and transplant. 1. The fresh seeds produced in the second year after transplanting are usually selected for seed collection. When the seed coat is blue or pink, it can be harvested, air-dried, threshed and stored. 2. The nursery land should be the leeward, shaded hillside or wasteland. Turn the ground in late May, use the burned weed ash as base fertilizer, turn it into the soil, and then rake flat to make a high border, 1.2m wide. Before sowing, apply base fertilizer, every 667m2 2500~3000kg, turn into the soil, fine and flat. Sow seeds from early to late June

Processing of the origin of Angelica sinensis
The processing of Angelica sinensis is directly related to the quality and medical effect. Because fresh Angelica contains more than 60% of the moisture and volatile oil of medicinal ingredients, if it is not processed in time, or if it is not processed well, it will become moldy and deteriorate. Angelica processing methods and procedures: 1, select, tie the recovered Angelica should be selected in time, the root rot, especially the water rot out, so as to prevent the spread of water rot. The selected Angelica sinensis stand was hung under dry and ventilated eaves for about 7 days to make its water evaporate and the roots softened and tied up with wicker or bark. Each fresh handful

Harvest and processing of Angelica sinensis (1)
(1) those propagated by direct seeding in the middle and late October of the second year or the seedlings and transplants were collected and dug when the plants were withered and yellow in the middle and last ten days of October of the same year. If the excavation is too early, the root strip is not full, the yield is low, and the quality is poor; too late, the soil has been frozen, so it is difficult to dig and easy to break the root. Before harvest, cut the stems and leaves on the ground and expose them to the sun for 3 to 5 days to make the roots fuller and fuller, and then carefully dig up the whole roots. (2) after processing and digging Angelica sinensis, it cannot be piled up. Remove the soil first, select a highly dry and ventilated place, spread out and dry until the roots become soft, or according to the number of roots.
