Spring planting dry Pinellia ternata
In recent years, there is a large gap between supply and demand in Pinellia ternata market, and the price is going up all the way, so we can develop production according to local conditions.
Planting on sloping land or intercropping with other crops is a shade-tolerant crop, which can be planted on a gentle slope, or intercropped with tall stalk crops such as young orchards and corn.
Sprouting is accelerated before sowing, and plastic film mulching at the seedling stage is usually sown from February to April. Before sowing, the seed stem was germinated in the indoor hotbed, and the bed temperature was kept at 20 ℃. It could sprout after 15 days. The seed stem was treated in a plastic greenhouse with a temperature of 20: 25 ℃ for 15 days, and the coleoptile was whitened before sowing. Cover with plastic film after sowing, remove the seedlings after uncovering.
Timely drainage and irrigation, timely fertilization and watering the planting land before planting, so as to facilitate seedling emergence. Keep the soil moist during the seedling growing period, irrigate in time in case of drought, and drain in time in the rainy season to avoid dead seedlings caused by stagnant water in the field. Apply enough base fertilizer, and the fertilizer is mainly farm manure. Topdressing was applied twice during the growing period. When plant buds grow on the inner side of the lower petiole from late May to early June, 2000 kg of mature human and animal manure and 25 kg of rotten cake fertilizer are applied per mu between rows. After falling seedlings in August, when the new buds appeared in the seed Pinellia ternata, and when the mother Pinellia ternata shelled and grew new roots, 20 kg of rotten cake fertilizer, 15 kg of calcium superphosphate and 10 kg of urea were applied to the roots of the plant. Combine fertilization to cultivate soil and root.
About two months after removing the buds and sowing, the plants will bolting and blossom one after another, and the buds will be removed in time, so that nutrients can be concentrated and transported to the underground tubers to accelerate the growth of tubers so as to increase production.
Delay the seedling falling in Pinellia ternata with high temperature and strong light, the growth will stop, the light intensity should be reduced by proper shading, and the field temperature should be reduced by spraying water. Spraying an appropriate amount of 0.01% sodium sulfite solution to inhibit plant respiration can shorten the seedling stage or reduce the number of seedlings.

The method of planting Pinellia ternata in greenhouse
Pinellia ternata, also known as Pinellia ternata, Sanbaotiao, Ma Yuguo, is a commonly used Chinese herbal medicine, which is distributed in the north and south of our country. In recent years, due to the reclamation and utilization of barren mountains and the extensive use of herbicides in farmland, the ecological environment has been destroyed, the resources have decreased year by year, and the price has been rising. According to the survey, at present, Pinellia ternata commodities are scarce in 17 professional markets across the country, and the supply exceeds demand, and the market price is firm at 36-42 yuan / kg. Therefore, the market prospect of artificial planting Pinellia ternata is very broad. In recent years, we

Land selection and preparation of Angelica sinensis
The main results are as follows: 1. According to the growth habits of Angelica sinensis seedlings, we choose the land surrounded by mountains, loose, fertile soil, high humus content, leeward, short light time, cool and moist land to raise seedlings. Angelica sinensis seeds are small, bud top soil strength is weak, so it is necessary to fine soil preparation in order to ensure normal seedling emergence. Ploughing the soil in the first year to make the soil fully weathered, it is best to turn the soil three times from April to May of that year. The first and second turning depth is 24cm 30cm, and the third shallow turning is 915cm. Dry and burn the weeds, spread and turn them over.
