The Latest Detailed Tutorial on Angelica Dahurica Planting Techniques and Methods
Angelica dahurica is a perennial tall herbaceous plant whose root can be used as medicine and has extremely high medicinal value. It has effects such as dispelling disease and removing dampness, draining pus and promoting tissue regeneration, and activating blood circulation to relieve pain. It is mainly used to treat wind-cold colds, headaches, and toothaches, and can also be used to make spices, so it has relatively wide uses. It is artificially cultivated in all northern regions of our country. So how exactly is Angelica dahurica planted? Let's take a look at the detailed introduction.
1. Land selection and land preparation
Angelica dahurica has strong environmental adaptability. It is enough to choose a plot where crops such as cotton, corn, or wheat were previously planted for planting. After the previous crop is harvested, clean the weeds and residual plants and the previous crop, then deep plow the soil, expose it to the sun for a few days, then deep plow again, harrow finely, and level it, making high beds 20 cm high and 1-2 m wide. The bed surface is required to be level, and the bed ditch should be about 30 cm wide. During plowing, an appropriate amount of base fertilizer can be applied to provide what the plants need for growth.
2. Sowing
The main propagation method of Angelica dahurica is through seed sowing. It is best to sow the seeds of the current year in the same year. If old seeds are chosen for sowing, the germination rate is relatively low, and there is also a very high chance that they will not germinate. July each year is when Angelica dahurica seeds mature. At this time, harvest the seeds, dry them in the air, remove impurities, and then sow. Sowing can be done in spring or autumn, and sowing can also be divided into broadcast sowing, drill sowing, or hole sowing. In the north, most operations are mechanized, so broadcast sowing and drill sowing are used, while in the south hole sowing is used. Broadcast sowing and drill sowing require 1 kg of seed per mu, while hole sowing requires only 0.6 kg. After sowing, do not cover with soil immediately. Apply some fertilizer, or cover with plant ash, and then cover with soil and water.
3. Seedling stage management
When the seedlings grow to 5-6 cm, thinning should be carried out. During thinning, appropriately remove some weak seedlings and cultivate strong seedlings. Thinning can make the seedlings distribute evenly and increase the ventilation and light transmission of the plants. When the seedlings grow to about 15 cm, transplanting can begin. During transplanting, keep 1-2 strong seedlings per hole, pay attention to removing diseased or weak seedlings, and also remove those whose stems have already turned greenish-white, so as to reduce the occurrence of bolting Angelica dahurica later.
4. Field management
During thinning, 2-3 times of intertillage and weeding should be carried out accordingly. The first time is when the seedlings are below 5 cm, at which time weeds should be pulled out by hand to avoid damaging the root system. If the soil is compacted, shallow cultivation of 2-3 cm can be done appropriately. The second time is when the seedlings grow to 6-10 cm, at which time deeper cultivation can be done slightly. The third time is when the seedlings are fixed, and when loosening the soil, all weeds should be removed. Fertilization of Angelica dahurica is generally carried out in the second year after sowing. At this time, it can be combined with thinning or intertillage, applying 3000 kg per mu of stacked fertilizer, applied in furrows.
