Planting status and Development suggestions of Pinellia ternata

Chinese herbal medicine Pinellia ternata is used to be called "dry" Pinellia ternata in order to distinguish it from Pinellia ternata. There are many local names, such as "wild taro" in Jiangsu, "naughty dog eggs" in Henan, "Laoxian eyes" in Jiangxi, "small Pinellia ternata" in Yunnan, "crow taro" in Shandong, "three-step jumping" in Hubei, "Ma taro" in Sichuan and so on. It belongs to the dry tuber of Pinellia ternata of Araceae. It has some special growth habits, such as shallow love of fertilizer, fear of strong light, fear of high temperature, fear of moisture, fear of drought, fear of waterlogging and so on. In order to meet the above growth habits in artificial planting, Shandong Heze Runkang traditional Chinese Medicine Research Institute and relevant researchers have done a lot of research over the past few decades and summed up a lot of planting management technology experience, but because of various factors, these technologies have not been popularized. At present, most Pinellia ternata growers only learn some superficial theoretical knowledge from the Internet or books, and do not fully master practical planting management techniques; therefore, the current artificial planting of Pinellia ternata has low output, poor quality, unstable output and other reality; therefore, there are few supplies on the market, and prices are rising year by year.

Since 2000, the price of Pinellia ternata has risen steadily from 20 yuan / kg to the current 120 yuan / kg (September 10, 2010), rising every year, unlike other varieties of traditional Chinese medicine. Because of the rise in prices, there are a lot of new growers every year. However, the increase of planting area does not necessarily increase the supply of goods, because most growers only look at the price and imagine the benefits, ignoring the fact that they have the conditions, technical difficulties, low or even no yield caused by the disease. sow in the field the limited tuber resources (the provenance of planting Pinellia ternata with fresh tuber) resources in this year's market, and there are not many seeds planted in Pinellia ternata at the time of harvest. Therefore, the more plants are planted, the more seeds are used, and the fewer commodities are on the market, and the supply of Pinellia ternata is reduced year after year; in addition, a large amount of labor is used in the production of Pinellia ternata, and the price of labor rises, which is also one of the main factors causing the annual price rise of Pinellia ternata.

In order to alleviate the contradiction between supply and demand of Pinellia ternata, meet the demand of pharmaceutical and international market, and increase the income of pharmaceutical farmers, it is suggested that qualified pharmaceutical farmers can develop appropriately. Technicians from Runkang Institute of traditional Chinese Medicine in Heze City, Shandong Province remind the majority of medicine farmers that planting Pinellia ternata must have the following conditions: (1) the soil must be loam or sandy loam, not too acidic and too alkaline, PH is between 6.57.5, there are no or very few root weeds and stones in the soil; (2) the soil is fertile and the content of organic matter is more than 1.2%. (3) sufficient water source, convenient watering, and complete drainage; (4) the terrain has a certain slope, the best slope is 5-10 degrees, there is no slope, it is necessary to make multiple ditches. Drug farmers who want to grow Pinellia ternata should first compare the above conditions one by one to see if they are suitable; if they meet the above conditions, then determine the planting area according to the technical and economic conditions they have mastered or learned. According to the current technical level and field production practice, if we meet the above four natural conditions, and on the basis of technology, we can meet the needs of Pinellia ternata growth, generally 120 kilograms of dried Pinellia ternata can be produced per mu. According to the current market price of 120 yuan / kg (September 10, 2010), the benefit per mu can reach more than 10,000 yuan, and the income is considerable. However, do not only pay attention to high efficiency, ignore the technical strength and conditions, touch the year, touch the weather, be careless, follow the trend of development, and plant blindly, so as not to cause unnecessary losses to yourself and the market.
