Five measures for High yield of Pinellia ternata

Pinellia ternata alias three-leaf Pinellia ternata, three-step jump, Ma Yuguo, to tuber medicine, as a commonly used Chinese herbal medicine. In order to obtain high yield in cultivated Pinellia ternata, the following measures must be taken:

The main results are as follows: 1. Before sowing, Pinellia ternata is generally sown from February to April in spring. because the temperature is low at this time, the seed stem germinates slowly, so it should be accelerated before sowing. Sprouting is carried out in indoor hotbed, the budding temperature is kept at about 20 ℃, budding can be produced in 15 days, and it can also be accelerated by setting up a plastic grid outside, the temperature is 20: 25 ℃, continuous treatment for 15 days, and the coleoptile is found to be white. After sowing, cover with plastic film, as long as the plastic film can cover the rows with seed stems, wait for the seedlings to be removed.

2. Timely irrigation and drainage, timely topdressing, dry Pinellia ternata like moisture, fertilizer tolerance, fear of stagnant water, before planting, the planting land should be watered once to facilitate seedling emergence. It is necessary to keep the soil moist during the seedling growth period, timely watering in case of drought, and timely drainage in the rainy season to avoid the death of seedlings due to stagnant water in the field. The main fertilizer is farm manure. In addition to applying sufficient base fertilizer, topdressing should be applied twice during the growing period. The first time from late May to early June, when bulblets grew in the lower part of the petiole, 2000 kg of mature human and animal manure and 25 kg of rotten cake fertilizer were applied to the interrow mu, and when the new buds appeared and the mother Pinellia ternata shelled and grew again in August, 20 kg of rotten cake fertilizer, 15 kg of calcium superphosphate and 10 kg urea per mu were mixed evenly and applied to the lower part of the plant, combined with fertilization.

3. Selecting semi-shady and semi-sunny sloping land or intercropping with tall stalk crops to interplant Pinellia ternata belongs to shade-tolerant crops, the growth is good and the yield is high in shady environment. Therefore, the planting land should be planted on a gentle slope with half shade and half yang, or interplanted with young fruit trees, corn, @ # @ 245 crops and other crops.

4. About 2 months after picking the buds and sowing in Pinellia ternata, the plants will bolt and blossom one after another, which is easy to consume nutrients. Therefore, in addition to keeping seeds, flower buds should be removed in batches in time to concentrate nutrients into underground tubers, accelerate tuber growth and help to increase production.

5. Delaying plant seedling falling, drought and Pinellia ternata will naturally fall seedling phenomenon and stop growing in Pinellia ternata. Therefore, delaying the fall of seedlings is an important measure for high yield of Pinellia ternata. According to the production experience, in addition to taking appropriate shading and sprinkler irrigation measures to reduce light intensity and air temperature, 0.01% sodium sulfite solution can also be sprayed appropriately to inhibit plant respiration, so as to shorten the seedling falling period or reduce the seedling falling times. to achieve the purpose of increasing production.
