Medicinal Herb Cultivation 0 views
Pinellia ternata is a medicinal herb harvested year-round. If high-yield, multi-crop cultivation techniques are adopted, 3 plantings and 3 harvests per year can be achieved. The cultivation techniques are as follows: 1. Land selection and preparation: For cultivating Pinellia ternata, loose and fertile soil is best. During land preparation, apply 3000-5000 kg of farmyard manure, 25-30 kg of phosphate fertilizer, and 25-30 kg of urea per mu, then plow deep and harrow fine. 2. Sowing method: Usually tuber propagation is used, allowing 3 plantings and 3 harvests per year, namely planting in April and harvesting in July, planting in July and harvesting in October, planting in October

Pinellia ternata is a medicinal herb harvested year-round. If high-yield, multi-crop cultivation techniques are adopted, 3 plantings and 3 harvests per year can be achieved. The cultivation techniques are as follows:

1. Land selection and preparation: For cultivating Pinellia ternata, loose and fertile soil is best. During land preparation, apply 3000-5000 kg of farmyard manure, 25-30 kg of phosphate fertilizer, and 25-30 kg of urea per mu, then plow deep and harrow fine.

2. Sowing method: Usually tuber propagation is used, allowing 3 plantings and 3 harvests per year, namely planting in April and harvesting in July, planting in July and harvesting in October, planting in October and harvesting in April of the following year. Alternatively, it can be harvested once a year. The amount of seed used per mu varies with tuber size. When planting, open furrows with a seed drill, with a row spacing of 18 cm and a plant spacing of 10-15 cm. After sowing, cover with soil and press firm. If dry weather occurs, water promptly.

3. Field management: Mainly do a good job of weeding and earthing up. When weeding, go shallow first and then deep. About 1 month after Pinellia ternata growth, plantlets form on the petioles, and then earthing up begins. Phosphate fertilizer and farmyard manure or potassium dihydrogen phosphate can be applied as topdressing. If drought occurs, water frequently in small amounts, and after watering, weed and earth up. In the later growth stage of Pinellia ternata, remove the flower buds to avoid consuming nutrients and affecting yield.

4. Disease control: Spray 1500-fold solution of Zhibingling, or 100-fold solution of 50% carbendazim and phoxim to control leaf spot disease and root rot.

5. Harvesting: Plow with a plow and carefully sort. The large ones are used for medicine, and the small ones are used as seed. Before medicinal use, first pile the fresh Pinellia ternata indoors for 4-5 days, then put it into hemp sacks or woven bags and rub with sand to peel off the skin, rinse away the skin residue in water, and after drying in the sun it is ready @#@136@#@. Generally, the yield per mu is 600-750 kg of fresh product.
