Detailed Explanation of Dictamnus dasycarpus Planting Techniques and Field Management Methods

Dictamnus dasycarpus is the root bark of the perennial herb Dictamnus dasycarpus, which has the effects of clearing heat and drying dampness, dispelling wind and removing toxins, and has relatively high planting value. What are the Dictamnus dasycarpus planting techniques?

1. Soil: The seedling-raising site for Dictamnus dasycarpus should be chosen as flat land or gentle slope land with sufficient sunlight, fertile and loose soil, and good drainage, sandy loam soil; low-lying waterlogged land, saline-alkali land, or heavy clay land is not suitable, and it is best to have irrigation and drainage conditions.

2. Sowing: Spring sowing of Dictamnus dasycarpus is carried out from late April to mid-May. Mix the seeds evenly with 3 times their volume of fine river sand and broadcast them, using about 20 grams per sq m, then cover with 1 cm of fine soil, and then cover with 1 to 2 cm of Chinese pine or larch pine needles. Autumn sowing is carried out from early October to early November. Mix the seeds evenly with 3 times their volume of fine river sand and broadcast them, using about 20 grams per sq m, then cover with 1 cm of fine soil, and then cover with 1 to 2 cm of Chinese pine or larch pine needles.

3. Site selection: The transplanting site for Dictamnus dasycarpus should be chosen as gentle slope land with deep soil layers and good drainage. In mountainous areas, sunny hillside wasteland, orchards, and the inter-row spaces of young artificial forests can be used for cultivation, and the low shrub spaces of oak silkworm farms and hazelnut orchards can also be used for cultivation.

4. Transplanting: The planting depth of Dictamnus dasycarpus is determined by the size of the root system of the transplanted seedlings. Place the seedlings in the transplanting trench with the terminal buds pointing upward, and the terminal buds should be 1 to 2 cm below the bed surface. Spread the roots out with a plant spacing of 35 to 40 cm. After placing them, cover with soil, then level the bed surface after covering with soil, and press lightly.

5. Weeding: In the first two years after transplanting Dictamnus dasycarpus, the seedlings are small, so follow the principle of removing weeds as soon as they are seen, and weed 3 to 4 times per year. After 3 years, the plants have already grown very tall, and the impact of weeds on them is relatively small, so the number of weedings is relatively reduced.

6. Fertilization: Apply topdressing to Dictamnus dasycarpus twice from late May to early June, applying 800 to 1000 kg of farmyard manure per mu or 8 to 10 kg of urea, and after the Beginning of Autumn, spray 0.3% to 0.5% potassium dihydrogen phosphate foliar fertilizer once.

7. Pest and disease control: Downy mildew, sclerotinia disease, and rust are the most common diseases of Dictamnus dasycarpus, and the yellow swallowtail butterfly is the most common pest. Control should be carried out according to the actual situation.

The planting management of Dictamnus dasycarpus is relatively simple, but the growth cycle is relatively long. If you want to plant Dictamnus dasycarpus, you should be prepared for a long-term effort.
