When is the latest planting time for Angelica dahurica?

Angelica dahurica prefers a mild and humid climate and a sunny environment, is cold-tolerant, and often grows under forests, at forest edges, beside streams, in thickets and in valley areas. It is mostly cultivated for medicinal use in the northern provinces of China. Correctly mastering the planting time of Angelica dahurica is the key to increasing its yield. Let's take a look together at the planting time of Angelica dahurica!

Sowing time of Angelica dahurica

1. Spring sowing: Spring sowing usually takes place around Qingming, but the yield is low and the quality is poor, so it is generally not adopted.

2. Autumn sowing: Autumn sowing cannot be too early or too late. It cannot be earlier than Chushu, otherwise the plants will grow rapidly in the winter of that year, and most plants will bolt and flower in the second year, and their roots cannot be used for medicinal purposes. But it cannot be later than Qiufen, because after Qiufen the rainfall gradually decreases and the temperature turns lower, and after sowing, Angelica dahurica cannot germinate for a long time, affecting growth and yield. Therefore, sowing should be done from early August to early September.

Sowing methods of Angelica dahurica

Angelica dahurica is suitable for direct sowing and not for raising seedlings and transplanting. Transplanted plants have forked roots and poor root growth, affecting yield and quality. Hole sowing and drill sowing are adopted. Before sowing, water the bed thoroughly, and after the water seeps down, begin sowing. Before sowing, the seeds should be mechanically treated to remove the winged seed membrane, then soaked in warm water (45°C) for 6 hours, taken out, wiped dry and sown.

1. Hole sowing: Open holes at a row spacing of about 33 cm and a plant spacing of 16-20 cm, with a hole depth of 6-10 cm. After sowing, water, sprinkle water or cover with grass to keep the soil moist regularly. Seedlings emerge 0-20 days after sowing. Autumn-sown Angelica dahurica has a large main root and high yield.

2. Drill sowing: Open furrows at a row spacing of 33 cm, scatter the seeds evenly, and cover with a layer of fine soil. The sowing rate is more than 15 kg per hectare. The rest is the same as hole sowing.

Harvest time of Angelica dahurica

1. Spring-sown Angelica dahurica can be harvested in the same year, in mid-to-late September.

2. Autumn-sown Angelica dahurica is harvested in late August of the second year when the leaves show a withered state. When the leaves turn orange-yellow, begin harvesting. Choose a sunny day, cut off the leaves of Angelica dahurica to use as compost, then use a tooth rake to dig up the roots one by one, shake off the soil, transport them to the drying yard, and process them.
