Detailed Explanation of the One-Year Three-Harvest Cultivation and Processing Technology for Pinellia (Pinellia ternata)
I. Land Selection and Preparation For planting Pinellia, loose and fertile soil is best. When preparing the land, apply 3000-5000 kg of farmyard manure per mu, 25-30 kg of phosphate fertilizer, and 100 kg of plant ash; do not apply ammonium bicarbonate. Plow deeply and harrow finely, with beds 1.3 m wide and 0.17 m high, and ditches 0.3 m wide; tall crops such as wheat, corn, sorghum, or kenaf can be intercropped in the ditches. II. Sowing Method Usually tuber propagation is used, allowing three plantings and three harvests in one 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. The amount of seed tubers used per mu varies with

Discovery of a Wild Self-Seeding Fertile Pinellia Plant and Analysis of Its Utilization Prospects
Since 1988, we have conducted surveys of wild Pinellia ternata variety resources in the Yimeng Mountain area and research on artificial cultivation techniques. During many years of investigation and study, we discovered a single Pinellia ternata plant that can self-pollinate and set seed under wild conditions. After artificial domestication and cultivation, one 1.5 g Pinellia tuber can produce 40 to 50 seeds in one year, thereby solving the problems of low natural seed-setting rate and the lack of five usable [varieties] in production, and opening a path for improving the propagation rate of Pinellia ternata. 1 Botanical characteristics: the plant is 10 cm tall

Natural color-enhancing feeds for laying hens include pine needles, black locust leaves and mugwort leaves
Pine needle powder: made by air-drying and grinding pine needles. Generally, adding 3 percent to 5 percent to the feed gives a good color-enhancing effect, and can increase the egg production rate by 13 percent. Black locust leaf powder: the added amount of black locust leaf powder accounts for 5 percent of the feed, and the effect is better than pine needles; the yolk color can be raised from grade 1 to grade 9 and can remain stable without changing. Mugwort leaf powder: mugwort leaves contain nutrients such as fat, protein and various amino acids. Adding 2 percent to 3 percent mugwort leaf powder to the chicken diet can increase egg production by 12 percent to

Symptoms and control methods of pinellia virus disease
It mostly occurs in summer; infected leaves curl and twist, and the plants grow stunted. Control methods: ① Select disease-free plants for seed. ② Disinfect the soil before sowing and control pests promptly. ③ When diseased plants are found, pull them out immediately, burn them in a centralized pile and bury them deep, and pour 5% lime milk into the diseased planting holes.

Key Techniques for High-Quality and High-Yield Cultivation of Pinellia ternata
1. Site selection and land preparation Creating a good growing and cultivation environment is the basic condition for high yield of Pinellia ternata. Under long-term wild ecological conditions, Pinellia ternata has developed characteristics of preferring a mild and humid climate and shaded environment, fearing high temperatures, drought and intense sunlight, and being able to tolerate cold. Therefore, the planting site for Pinellia ternata should be selected in sandy loam soil on sunny-facing terraces, terraced fields or gentle slopes close to a water source. The soil is required to be loose, fertile and well-drained. The previous crop is best as corn or rapeseed. After selecting the site, in combination with autumn plowing and land preparation, apply per mu decomposed chicken manure

A Brief Introduction to the Key Points of Fertilization Techniques for Pinellia ternata
A perennial herb of the Araceae family. Mainly produced in Henan, Sichuan, Guizhou, Jiangsu, Hubei, Anhui, Zhejiang and other provinces. The medicinal part is the rhizome. Pinellia ternata has a shallow root system. It prefers a mild, humid climate and a shaded environment, and is afraid of high temperatures, drought and strong light. It is suitable for loose-textured, well-drained sandy loam soil. Key points of fertilization techniques: Base fertilizer, apply 3000-4000 kg of barnyard manure per 667 sq m. Topdressing, from late May to early June, when bulbils grow out from the lower part of the petiole, apply a mixed fertilizer of 500-1000 kg of barnyard manure and

What is the annual yield per mu of Pinellia ternata with three plantings and three harvests?
If Pinellia ternata is propagated from tubers, hotbeds or electrically heated hotbeds should be used to sprout them. In early March, that is, between Yushui (Rain Water) and Jingzhe (Awakening of Insects), when the 5 cm soil temperature is stable at 8-10°C, it can be sown, and in the same year or the following year in mid-June, between Mangzhong (Grain in Ear) and Xiazhi (Summer Solstice), it can be dug up without affecting summer-sown autumn crops. Pinellia ternata generally yields 600-800 kg/mu of fresh tubers, with a drying ratio of 25%-30%, which can be converted to 180-240 kg/mu of dried product.

Symptoms, Identification and Control Methods of Pinellia Leaf Spot
It occurs in early summer. Purple-brown spots appear on diseased leaves, and later many small black dots form on the lesions. In severe cases, the lesions cover the entire leaf, causing the leaves to curl, scorch and die. Control methods: In the early stage of the disease, spray 1:1:120 Bordeaux mixture or 65% zineb 500-fold solution, once every 7-10 days, for 2-3 consecutive applications.

Clever Seed Treatment Methods and Key Technical Points for Pinellia ternata
Treating the seeds of medicinal herbs before sowing plays a major role in preventing and controlling pests and diseases, raising the germination rate, and ensuring uniform, complete and vigorous seedlings. It is the primary prerequisite for stable and high yields, generally increasing the yield by 5%-20%. The methods for treating Pinellia ternata seeds are described below: (1) before sowing, soak the seeds in a 3-fold dilution of 50% carbendazim plus 40% phosethyl-Al (yield increase is significant); (2) soak the seeds separately in a 300-fold dilution of rice vinegar, 50 mg/L potassium permanganate, and 5% plant ash solution (prevents root rot).

Key Techniques for High-Quality and High-Yield Cultivation and Management of Pinellia ternata
I. Site Selection and Preparation. Pinellia ternata prefers a warm and humid environment. The planting site should be chosen as a small flat area on gentle mountain slopes at high altitude, with loose, fertile, moist soil and not strong sunlight. The land should be plowed and broken up several times. Apply 3000-4000 kg of farmyard manure per mu as base fertilizer. Make raised beds 20 cm high and 100-120 cm wide. Since Pinellia ternata is a shade-tolerant plant, it can be intercropped under orchards and tall crops. II. Propagation Methods. (1) Corm propagation. In November-December, select disease-free,
