A Chuanshegan planting method that shortens planting period and increases yield

Abstract

The invention discloses a rhiaoma iridis tectori planting method for shortening planting period and improving yield. The method comprises the steps of land selection, base fertilizer applying, seed treatment, seeding, filed management, ex-root spraying, harvesting and processing, wherein the seed treatment comprises the steps of soaking seeds with clear water for 5-10 days, changing the water for 3-4 times during a soaking period, and then soaking with a brassinolide aqueous solution for 5-10 hours; the ex-root spraying comprises the steps of starting spraying a JA (Jasmonic Acid) spraying solution in the early blooming period of the rhiaoma iridis tectori, stopping spraying when flowers begin to wither away, and spraying the JA spraying solution once every 10-15 days, with 3-8 times in total, therefore the planting period of the rhiaoma iridis tectori can be shortened, the yield of the rhiaoma iridis tectori can be improved, the problem that rhiaoma iridis tectori obtained by the conventional planting method can be harvested after three years, and the period is too long can be solved, and the problem that the yield of the rhiaoma iridis tectori is behind the requirement due to increasingly increased quantity demanded of the rhiaoma iridis tectori can be further solved. According to the rhiaoma iridis tectori planting method, the planting period of the rhiaoma iridis tectori propagated by the seeds can be reduced to 2 years from 3 years, the yield of the rhiaoma iridis tectori can be improved by about 30%, the plant diseases and insect pests can be alleviated, the application of pesticides can be reduced, and the environmental pollution can be reduced.

Description

technical field [0001] The invention relates to a method for planting Chuanshegan, in particular to a method for planting Chuanshegan which shortens the planting period and increases yield. Background technique [0002] Chuanshegan is the dried rhizome of Irisaceae plant Iris (Iristectorum Maxim.), which is a perennial herb and is used as medicine with its rhizome. Chuanshegan grows in wetlands under forests, at the foot of mountains and beside streams. It grows in most parts of my country. It is mainly produced in Guangdong, Guangxi, and Sichuan. Chuanshegan is a good medicine for clearing away heat and detoxification, and it is widely used clinically to fight influenza, treat sore throat, and pharyngitis. 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 excavation. The large-scale excavation in successive years has s...
