Planting method capable of improving medicinal effect of charred pinellia ternata

Abstract

The invention relates to the technical field of Chinese herb planting, in particular to a planting method capable of improving the medicinal effect of charred pinellia ternata. Specifically, the method includes the steps that in the middle growing period of pinellia ternate, urea is applied once; on the third to fifth day after urea application, the whole field is irrigated once when it is sunny; from the second day after irrigation, on every sunny day, shading is conducted during 11:00-13:00 at noon; from the second day after shading, on every sunny day, the whole field is sprayed with water once during 7:00-8:00 in the morning. By means of the planting steps of the method, it is guranateed that the content of alkaloid in charred pinellia ternata is increased, the phenomena that due to application of nitrogen fertilizer, diseases occur frequently, absorption of other elements is inhibited, the overground parts of tuber or root crops grow vigorously but the size and number of underground parts are small are avoided, the medicinal quality of pinellia ternata is guranateed, and a high yield is also guranateed; besides, the planting method is low in implementation difficulty.

Description

technical field [0001] The invention relates to the technical field of planting Chinese herbal medicines, in particular to a planting method for improving the medicinal efficacy of Jiao Pinellia. Background technique [0002] Pinellia is an Araceae plant, a perennial herb, and its tubers can be used as medicine. Because the Pinellia produced in Jiaobei Town, Funan County, Anhui Province has pure medicinal properties, it is highly valued by doctors. Used as medicine, pinellia is a widely distributed species. Modern pharmacological studies have shown that pinellia not only affects the respiratory system, digestive system, and circulatory system to varying degrees, but also has anti-tumor, anti-early pregnancy, analgesic, sedative, and hypnotic effects. , alkaloids are the main physiologically active substances of pinellia tubers, which have the functions of anti-nausea, antitussive, expectorant, anti-stress, lipid-lowering, anti-tumor and improving memory. Alkaloids are nitrog...

[0002] Pinellia is an Araceae plant, a perennial herb, and its tubers can be used as medicine. Because the Pinellia produced in Jiaobei Town, Funan County, Anhui Province has pure medicinal properties, it is highly valued by doctors. Used as medicine, pinellia is a widely distributed species. Modern pharmacological studies have shown that pinellia not only affects the respiratory system, digestive system, and circulatory system to varying degrees, but also has anti-tumor, anti-early pregnancy, analgesic, sedative, and hypnotic effects. , alkaloids are the main physiologically active substances of pinellia tubers, which have the functions of anti-nausea, antitussive, expectorant, anti-stress, lipid-lowering, anti-tumor and improving memory. Alkaloids are nitrogen-containing compounds. The synthesis and accumulation of alkaloids in the body have the effect of traditional Chinese medicine. At present, in order to increase the content of alkaloids in Pinellia, growers mainly apply more and more nitrogen fertilizers. However, excessive nitrogen fertilizer application will cause many hazards. First, the body of Pinellia Nitrogen will react with a large amount of carbohydrates to form protein, leaving a small amount of carbohydrates as the material to form the cell wall, so that the cell wall becomes thinner, the plant's disease resistance is weakened, the leaves, stems and other tissues are soft and juicy, and the disease is easy Invading from these places, pests also prefer to eat tender organs, resulting in severe disease

The second is that over-application of nitrogen fertilizer will inhibit the absorption of other elements, leading to the occurrence of nutrient deficiency and a series of corresponding reactions. Product yield and quality
