Problems solved by technology

[0005] Astragalus is usually bundled and packaged with sacks and supports, stored in a dry and ventilated place, the temperature is below 30°C, the relative humidity is 60-75%, and the water content of Astragalus is controlled at 10-13%. However, due to the uncontrollability of the natural environment, conventional Method storage Astragalus has a high incidence of mildew and moth
[0006] After consulting the prior art, there are existing methods for storing Radix Astragali, such as Chinese patent CN103933112A discloses a method for processing and packaging storage of Astragalus origin. Compared with the traditional method, the storage period is longer and the quality of the product is better, but the energy consumption is large, and the cost of processing and storage is high

Embodiment 1

[0019] Harvest Astragalus membranaceus that has grown for 2 to 3 years. Harvesting is carried out in autumn when the plants are withered. When harvesting, dig deep to avoid damaging the roots, so as to prevent the main root from being dug out, which will affect the yield and quality of medicinal materials; microwave drying method is adopted, and the power of microwave dryer is 12kw , set a constant drying temperature of 55 degrees Celsius, and a drying time of 60 minutes; use the mixed lime river sand burial method, spread a layer of mixed lime sand on the bottom of the storage container, with a thickness of 2 to 3 cm, and spread 3 to 4 cm thick gauze on the lime sand, Put the dried astragalus on the gauze, and then spread the same thickness of gauze and lime sand; keep the storage room cool, dry, ventilated, and dark, and check regularly to prevent moths, mildew, and mild moths. Take the drying method, and use methyl bromide to fumigate in severe cases.

Embodiment 2

[0021] Harvest the Astragalus membranaceus that has grown for 2 to 3 years, and harvest it before it germinates in spring. When harvesting, dig deep to avoid damaging the roots, so as to prevent the main root from being dug out, which will affect the yield and quality of medicinal materials; microwave drying method is adopted, and the power of the microwave dryer is 12kw , set a constant drying temperature of 55 degrees Celsius, and a drying time of 60 minutes; use the mixed lime river sand burial method, spread a layer of mixed lime sand on the bottom of the storage container, with a thickness of 2 to 3 cm, and spread 3 to 4 cm thick gauze on the lime sand, Put the dried astragalus on the gauze, and then spread the same thickness of gauze and lime sand; keep the storage room cool, dry, ventilated, and dark, and check regularly to prevent moths, mildew, and mild moths Take the drying method, and use methyl bromide to fumigate in severe cases.

Abstract

The invention discloses an insect-proofing method for storing astragalus membranaceus, and belongs to the technical field of processing and storage of traditional Chinese medicines. The astragalus membranaceus is treated by four steps of harvesting, drying, storage and maintenance; the astragalus membranaceus is effectively prevented from being damaged by insects by physical and chemical means. The method has the advantages of long storage period, good effect, simple and easy operation and low cost.

Description

technical field [0001] The invention belongs to the field of processing and storage of traditional Chinese medicinal materials, in particular to an insect-proof method for storing Astragalus membranaceus. Background technique [0002] Astragalus is the dried root of the leguminous plant Astragalus mongolica or Astragalus membranaceus. It is mainly produced in Qiqihar and Ning'an in Heilongjiang, Hunyuan, Fanzhi, Yingxian, Yuanping, Guangling and northern Shanxi in Shanxi, Minxian, Dangchang and Wudu in Gansu, Chifeng City and Wulanchabu League in Inner Mongolia and so on. [0003] Astragalus likes sunlight, is resistant to drought, is afraid of waterlogging, likes cool climates, has strong cold resistance, can tolerate low temperatures below -30°C, is afraid of heat, and has strong adaptability. It mostly grows on arid sunny grasslands in mountainous areas or mid-mountainous areas at an altitude of 800-1300m, or between sunny forest edge bushes; the vegetation is mostly co...
