spa II. Biological Characteristics

  • Stems & Roots: Perennial herb, over 1m high. Rhizomes develop strongly, which is the used part. Pseudostems formed by leaf sheaths.
  • Leaves: Broad leaves, similar to 'dong' leaves, light green, smooth surface, soft, with a pleasant fragrance.
  • Climate: Prefers mild climate, tolerates heat and humidity, drought tolerant, does not tolerate waterlogging.
  • Light: Light-loving, can grow at forest edges, under sparse canopy.
  • Soil: Not picky about soil, but loose soil, rich in organic matter, with a thick cultivated layer is best for growth.

agriculture III. Cultivation Techniques

1. Season & Soil

  • Season: Best from mid-February to mid-March. Late planting from late March to early April. In warm dry places, can plant multiple crops.
  • Soil: Plow thoroughly, clear weeds. Beds 1.1 - 1.2m wide, 0.25 - 0.30m high, furrow 0.25 - 0.3m wide.

2. Fertilizers (per 1,000m²)

  • check_circle Organic fertilizer: 1.5 - 2.0 tons
  • check_circle NPK: 40 - 50kg
  • check_circle Superphosphate: 25 - 30kg
  • check_circle Potassium chloride: 15 - 20kg

* Basal application: All organic fertilizer, phosphorus and 1/3 potassium in holes/furrows before planting. Mix well with soil.

3. Spacing & Planting

  • Spacing: Rows 50-60cm apart, plants 40-50cm apart.
  • Seed: Select healthy rhizomes, disease-free. Cut into small sections (2-3 buds).
  • Planting: Place rhizomes in holes/furrows, cover with 5-7cm of soil.

4. Care

  • Watering: Twice daily (morning, afternoon) until sprouting. Then furrow irrigation or as available. Keep moist during strong growth and tuber formation.
  • Weeding/Earthing up: 25-30 days after planting, hoe the surface, hill up soil to base, remove weeds. Only earth up in early stages.
  • Top dressing:
    - Use 7-10kg NPK/time. Dissolve (1.5-2%) or dry application (7-10cm from base).
    - Tuber formation period: Add Potassium (5-7kg/time).

inventory_2 IV. Harvest & Seed Saving

  • Timing: Can harvest for seed after 12-13 months. Commercial harvest needs mature rhizomes for best fragrance.
  • Signs: Old leaves/stems, firm/hard rhizomes.
  • Pre-harvest: Let field dry for 30-40 days.
  • Method: Hoe both sides of bed, pull up whole plant, cut stems/leaves, shake off soil. Or cut stems first then dig.
  • Seed Storage: Air dry skin then store in cool place.
