- Land preparation and fertilization
- Select high-lying, well-drained fields, and cultivate them in depth. Combined with land preparation, apply sufficient base fertilizer: apply 3,000 kg of soil fertilizer per acre, 20 kg of urea, and 50 kg of phosphorus and potassium fertilizer, and then make hoe, waiting for sowing.
- sowing
- Rubia cordifolia is propagated with seeds and can also be propagated by cuttings. The sowing period is divided into spring sowing and autumn sowing. Spring sowing is around Qingming, autumn sowing is before freezing.
- Seed propagation: Before the sowing, open a shallow trench on the prepared surface, and then sprinkle the seeds evenly into the trench, cover the soil, water, and protect the hoe to facilitate emergence. The line spacing is 30 cm. Seeding rate per acre is 3 kg. After the emergence of madder grass, field management should be strengthened, and it can be transplanted after one year of growth. When transplanting, the madder seedlings were planted on the whole hoe surface according to the row spacing of 50 × 30 cm, and watered to protect the hoe for survival.
- Cutting propagation: Stem vines with robust growth, full development and no pests are selected, and cuttings are cut every 2-3 knots. It is inserted into the soil at a distance of about 10 × 5 cm according to the row of plants, and 1 knot is exposed. Watering, protecting and shading for survival. It can be transplanted after 1 year of cultivation.
- Field management
- After the madder is planted, pay attention to weeding. Water in a timely manner in dry weather, and pay attention to drainage in rainy weather. When the seedlings are 30 cm high, pillars are erected beside the plants for climbing. After the buds are present, they should be removed in addition to the remaining plants to reduce nutrient consumption.
- Pest Control
- Rubia root rot can be controlled with 1: 1 Bordeaux solution or carbendazim at the beginning of the disease. Powdery mildew is used to prevent powdery mildew. The main pests are aphids and red spiders, which can be controlled by aphids.
- Harvest and processing
- Rubia cordifolia is generally excavated in the autumn 2 to 3 years after transplantation, after the ground stems and leaves wither. First cut off the ground vines, then plan out the underground roots, clean the soil, and dry it before selling it. The yield per mu is 150 kg. [1]
