Planting technique of Pinellia ternata: what method can increase production by planting Pinellia ternata?

What method can be used to increase production by planting Pinellia ternata? Experienced netizens give help to introduce the methods of planting Pinellia ternata if you want to increase production, you can refer to the following methods for management: first, germination of Pinellia ternata seedlings before sowing: seedling mulched Pinellia ternata is generally sown from February to April in spring, due to the low temperature at this time, seed stem sprouting slowly, seed stem germination 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. Method 2. Timely irrigation and drainage in the field: topdressing Pinellia ternata on time likes to be moist, resistant to fertilizer, and afraid 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. For the first time from late May to early June, when bulbs grow on the inner side of the lower petiole, 2000 kg of mature human and animal manure and 25 kg of rotten cake fertilizer are applied to the interrow. For the second time, when the new buds appeared in the son Pinellia ternata and the new roots grew again after the shelling of the mother Pinellia ternata in August, 20 kg of rotten cake fertilizer, 15 kg calcium superphosphate and 10 kg urea per mu were mixed evenly and applied under the plant, combined with fertilization. Method 3. Selection of planting site of Pinellia ternata: Pinellia ternata is a shade-tolerant crop with good growth and high yield in shady environment. Therefore, the planting land should choose the gentle slope of half-shade and half-yang, or interplant with young fruit trees, corn, wheat and other crops. Method 4. Pick the buds of Pinellia ternata at the right time: about 2 months after sowing, 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. Method 5. Delay the seedling falling and stop growing in Pinellia ternata when it is exposed to high temperature and strong light. 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.
