Seed prices and planting methods

Angelica is one of the most commonly used traditional Chinese medicines, also known as Angelica sinensis, Angelica sinensis, Angelica sinensis and so on. Angelica sinensis belongs to perennial herbs in the umbrella family. China mainly produces southeast Gansu, with high yield and good quality in Minxian County, followed by Yunnan, Sichuan, Shaanxi, Hubei and other provinces, all for cultivation. Let's take a look at the seed price and planting methods of Angelica sinensis.

How much is the Angelica seed per jin?

The price of Angelica seeds is about 70,120 yuan per jin, but it varies greatly due to the quality, variety, origin and quantity of seeds. Angelica sinensis commonly used seeds for propagation, direct seeding or seedling transplanting, the amount of seeds per mu was about 12: 15 jin, the seeds germinated well within the range of 10-25 ℃, and emerged at 10-15 days after sowing, but it had the phenomenon of early bolting, which should be overcome in production. It can be dug in the third year, the yield per mu is 200 kg 300 jin, and the high yield can reach 500 kg 600 jin.

Growth habits of Angelica sinensis

Angelica sinensis is a low-temperature and long-day crop, suitable for cold and cool climate, and can be cultivated at an altitude of about 1500m to 3000m. In the low sea area, the bolting rate is high, and it is not easy to pass the summer. The seedling stage likes the shade, the transmittance is 10%, avoid the scorching sun, the adult plant can bear the strong light. It is suitable for the cultivation of deep, loose, well-drained and fertile sandy loam rich in humus, but not in low-lying stagnant water or easily hardened clay and barren sandy soil. The florescence is from June to July and the fruiting period is from July to September.

Sowing method of Angelica sinensis

1. Direct seeding: direct seeding is divided into strips and holes, and hole sowing is better. Seedlings can be determined when the height of the seedlings is 10 cm. There are 2 plants in each hole, the distance between plants is about 5 cm, and the distance between plants is 20 cm.

① Autumn Direct seeding: Danggui Autumn Direct seeding has a longer growth period and maintains the advantages of direct seeding than other seasons. It is suitable to sow seeds from late July to early August in high altitude areas with low temperatures, and from mid-August to early September in low altitude areas with slightly higher temperatures.

② Spring Direct seeding: Danggui Spring Direct seeding is a cultivation method of sowing in early spring and harvesting before winter. It is planted in the same year and harvested in the same year without early bolting. The disadvantage is that the yield is lower, but higher yield can be obtained under better cultivation conditions.

③ winter direct seeding: winter direct seeding is to sow the seeds before winter, make the seeds overwinter in the soil, and harvest at the end of the next autumn. During the overwintering period, the seeds can not accept the qualitative change of vernalization at low temperature in winter, so it can also prevent early bolting and the yield is higher than that of spring direct seeding.

2. Transplanting: Angelica sinensis is generally planted in spring, and the time is suitable before and after the Qingming Festival. Early seedlings are easy to be harmed by late frost, too late seedlings have germinated, easy to hurt buds, reduce the survival rate, planting methods are divided into holes and ditches.

① hole planting: the hole was staggered and dug according to the row spacing of 33 × 27 × 27 cm on the flat and fine planting ground, with a depth of 15 cm. Then each hole is arranged according to the shape of the product and planted into a large, medium and small seedling.

② trench planting: transversely trench on the finished border surface, ditch distance 40 cm, ditch depth 15 cm, plant spacing 3 cm to 5 cm, rhizome 2 cm below border surface, soil cover 2 cm.

Planting method of Angelica sinensis

1. Land selection and land preparation: Angelica transplanting land should choose wasteland or leisure land with deep soil layer, loose and fertile soil, high humus content, good drainage, deep ploughing before planting, combined with deep ploughing and applying base fertilizer. 6000kg / mu of rotten barnyard manure and 100kg of oil residue.

2. Seedling field management: uncover the grass when the return seedling is 1cm high, build a shed or cut branches to shade after uncovering the grass. In combination with weeding, the seedlings are removed and the weak remains strong. Topdressing can be carried out at the end of seedling growth, and it is better to apply available nitrogen fertilizer.

3. Check seedlings and replenish seedlings: Angelica can emerge one after another about 20 days after transplanting. If there is a lack of seedlings, they should be replanted in time. Weeding should be carried out for the first time when the seedling height is about 5 cm. Weeding should be done for 3 or 4 times from seedling emergence to ridge closure, and weeding should be combined with weeding to loosen the soil to prevent soil consolidation.

4. timely topdressing: the topdressing time of Angelica sinensis is in the peak leaf growth period in late June and the root growth period in early August, and the soil in the producing area is generally lack of phosphorus and potassium, so it is necessary to supplement phosphorus and potassium fertilizer. Potassium dihydrogen phosphate, diammonium phosphate and nitrogen, phosphorus and potassium compound fertilizer are usually used as topdressing fertilizer.

5. Irrigation and drainage: Angelica needs a moist soil environment for growth, and appropriate irrigation during drought is beneficial to high yield. Rain Water should pay attention to ditch drainage when there is too much, especially in the later stage of growth, the field can not accumulate water, otherwise it will cause root rot and cause root rot.

6. Loosening soil and cultivating soil: when Angelica sinensis grows to the middle and later stage (after August), the root system begins to develop and grows rapidly. At this time, soil cultivation can promote the development of body return and help to improve yield and quality.

7. Removal of the old leaves: the lower old leaves turn yellow due to lack of light after the closure of Angelica sinensis, and these old leaves should be removed in time, which can not only avoid unnecessary nutrient consumption, but also improve the ventilation and light transmission conditions within the population.

8. Timely extraction of moss: the roots of the early bolting plants of Angelica sinensis gradually become woody and become firewood roots, losing medicinal value. This kind of plant has strong vitality and consumes a lot of water and fertilizer, so it should be pulled out in time so as not to consume soil fertility and affect the growth of unbolted plants.
