When will Angelica dahurica be planted

The sowing time of Angelica dahurica is divided into spring and autumn. Spring sowing before and after the Qingming Festival, but the output is low, the quality is poor, generally not used. Autumn sowing can not be too late, the earliest can not be earlier than the End of Heat; otherwise, if it grows rapidly in the winter of that year, most of the beads will bolt and blossom in the second year, and their roots cannot be used for medicinal purposes, but no later than the Autumn Equinox; because the rainfall after the Autumn Equinox decreases gradually, and the temperature decreases, Angelica dahurica

Cultivation techniques of Radix angelicae Dahuricae

1. Cultivate seeds. Angelica dahurica Sichuan chooses the main root is not branched, strong and disease-free Angelica dahurica is selected as the seed. Henan and Hebei selected root strip slender, Reed head small, no root, thin skin white, robust Angelica dahurica as species. Cut off the leaves before transplanting and plant according to the row spacing of 50-70 cm. Weeding and fertilization were carried out in winter and the following spring. The seeds mature one after another from June to July. When the pericarp turns yellowish green (Henan yellow-white), the seeds can be harvested in batches together with the fruit sequence, then spread out in a ventilated and dry place, cool and dry to thresh and remove impurities.

2. Sowing seeds. Strip sowing and hole sowing are available. Zhejiang, Henan and Hebei are strip sowing, with row spacing of 13-20-27 cm, trenching of 1-1.5 cm, and seed use of 1-1.5 kg per mu. After sowing, flatten the border and water it to keep the soil moist. Sichuan multi-purpose acupoint sowing, row spacing of 30-33 cm, acupoint spacing of 23-27 cm, the bottom of the acupoint should be flat. The sowing rate is 0.5-0.8 kg per mu. After sowing, they did not cover the soil, and then applied sparse human and animal dung water, about 1000 kilograms per mu, and then covered it with plant ash mixed with human and animal dung water, without exposing seeds. Then use a plank to suppress or tread lightly, so that the seeds and soil close to facilitate germination. The seedlings can emerge in 15-20 days.

Fertilizer and Water Technology of Angelica dahurica

1. Fertilization. Generally, topdressing was carried out for 3-4 times, and the first and second times were carried out after interseedling and intertillage. 1500-2000 kg of sparse human and animal manure per mu each time. The third time after the seedling was fixed, 2000-3000 kg of human and animal manure water per mu and 3 kg of urea were added. Ching Ming Festival was fertilized for the fourth time before and after applying 2000-3000 kg of human and animal manure per mu and 150kg of plant ash. In Zhejiang, the first time was after seedling in March, the second time was after weeding in April, and the third time was fertilized before the Beginning of Summer. Ring fertilizer is usually applied in winter. Fertilization should pay attention to less application in that year, in order to prevent excessive growth, bolting and civilization in advance. It should be more in the second year, supplemented with phosphorus and potassium fertilizer to make the root stout.

2. Watering. Angelica dahurica During the growing period, if the weather is dry, it should be watered in time to ensure the needs of plant growth. when Rain Water is too much or stagnant water in the field, it should be drained in time to prevent disease or rotting roots.

Pest control of Angelica dahurica

1. Leaf spot blight: control methods: timely removal of diseased leaves and centralized burning; spray 400-500 times of Bordeaux solution or 65% zinc wettable powder before or at the beginning of the disease, once in 7-10 days, 2-3 times in a row.

2. Black Tsui. Harms the roots. Prevention and control methods. The soil around the root of the plant was irrigated with 1000 times of 25% ammonium parathion EC.

3. Heart-eating insects. Bite the seed, often make the seed grain no harvest. Prevention and control methods. Spray with 1000 times of 90% crystal trichlorfon.

4. Black spot. Black disease spots appear on autumn leaves, prevention and treatment methods. Diseased leaves were removed or Bordeaux solution of 1 ∶ 1 ∶ 120 was sprayed twice.

Angelica dahurica The method of planting is relatively simple. In the later stage of planting, it is necessary to strengthen its field management, proper watering, fertilization, pest control and so on. Only when these are done well, will the planted Angelica dahurica grow well and the yield is high.
