Rhiaoma iridis tectori planting method capable of increasing yield and contents of effective components

Abstract

The invention relates to a rhiaoma iridis tectori planting method capable of increasing the yield and the contents of effective components. The planting method comprises the steps of land selection, soil preparation and base fertilizer applying, division propagation, field management, outside root spraying, harvesting and processing, wherein the step of outside root spraying comprises spraying mixed water solution of salicylic acid and jasmonic acid at the beginning of rhiaoma iridis tectori blooming period, and stopping spraying until flowers begin to wither and fall, wherein spraying is carried out four to six times all together at an interval of 10-15 days so as to increase the yield of rhiaoma iridis tectori and the contents of effective components. The problems that the demand for rhiaoma iridis tectori increases day by day, the yield of rhiaoma iridis tectori is short of demand, and the contents of effective components are reduced since a large amount of pesticides are applied are solved. According to the method, the yield of rhiaoma iridis tectori can be increased to about 350 kg per mu from about 250 kg per mu, and is increased by about 40%; the content of the effective component of Tectoridin is increased to about 6% from about 4%, and is increased by about 50%; the content of ethanol-soluble extractives is increased to about 35% from about 27%, and is increased by about 30%; meanwhile, rhiaoma iridis tectori cannot be influenced by insect pests without application of pesticides, so that the application amount of the pesticides can be greatly reduced, pesticide residual is prevented, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to a method for planting chuanshegan, in particular to a method for planting chuanshegan to increase yield and content of active ingredients. Background technique [0002] Chuanshegan is the dried rhizome of Iris (Iristectorum Maxim), a perennial herb, and its rhizome is used as medicine. Chuanshegan grows in the forest, at the foot of the mountain and in the wetlands by the stream. It grows in most parts of my country. Guangdong, Guangxi, and Sichuan, the main ingredients are irisin, wild irisin, irisin A, diandimebiglucoside, irisin, etc. Chuanshegan is a good medicine for clearing away heat and detoxification, and it is widely used clinically to fight influenza and treat sore throat , Laryngitis and other diseases. In recent years, the research on the application of its glycosides has become more and more in-depth, and its uses are also increasing, and the demand is also increasing. The demand stimulates production and excavatio...
