Embodiment 1

[0031] The harvested fresh plants of the aerial part of A. japonica were sun-dried to a moisture content of 13%, pulverized by a plant pulverizer, all passed through a 1cm analytical sieve, and the pulverized E. japonica stems and leaves were filled into a steam explosion device In the process, steam explosion treatment was carried out, and the steam explosion conditions were that the pressure was maintained at 1.8MPa for 70 seconds, and then the explosion was instantaneous; A removal rate. The removal rate of Euptox A was 97.3%.

Embodiment 2

[0033] The harvested fresh plants of the aerial part of A. japonica were dried in a far-infrared oven to a moisture content of 12%, pulverized by a plant pulverizer, all passed through a 1cm analytical sieve, and the pulverized E. japonica stems and leaves were filled into In the steam explosion device, the steam explosion treatment is carried out, and the steam explosion condition is that the pressure is maintained at a pressure of 1.4MPa for 200 seconds, and then the explosion is instantaneous; , calculate the Euptox A removal rate. Euptox A removal rate is 100%.

Embodiment 3

[0035] The harvested fresh plants of the aerial part of A. japonica are naturally air-dried indoors to a moisture content of 12%, pulverized by a plant pulverizer, and all passed through a 1cm analytical sieve, and the pulverized E. japonica stems and leaves are filled into a steam explosion. In the device, steam explosion treatment is carried out, and the steam explosion condition is that the pressure is maintained at a pressure of 2.0 MPa for 40 seconds and then exploded instantly; Euptox A removal rate. The removal rate of Euptox A was 99.52%.

Abstract

The invention discloses a resource utilization method of ageratina adenophora, which comprises the following steps: drying and crushing fresh plants of the overground part of harvested ageratina adenophora, passing through a 1cm analysis sieve, filling the crushed ageratina adenophora stems and leaves into a steam explosion device, carrying out steam explosion treatment under the steam explosion condition that the pressure is 1.2-2.0 MPa, the pressure is maintained for 20-200 seconds, and then instantaneous explosion is carried out; after the eupatorium adenophorum is subjected to steam explosion treatment, the removal rate of the toxic component (9-carbonyl-10.11-dehydro-eupatolone) Euptox A of the eupatorium adenophorum can reach 95-100% according to the steam explosion pressure and the pressure maintaining time. According to the method, the eupatorium adenophorum is utilized in a resource mode, the damage degree of the eupatorium adenophorum to the ecological environment can be reduced to a certain degree, the eupatorium adenophorum can be turned into treasure, great economic benefits and ecological benefits are achieved, and a new effective way is provided for resource utilization of the eupatorium adenophorum. The method is short in detoxification time, high in efficacy, low in energy consumption and easy for industrial production.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for resource utilization of Rhododendron chinensis. Background technique [0002] Amethyst ( Eupatorium adenophora Spreng.), also known as liberation grass, red deer grass, destroying grass, plane grass, and zelan, is a worldwide invasive weed and is a perennial bushy semi-shrub herb of the Compositae family. Originating from Mexico to Costa Rica in South America, it is now widely distributed in more than 30 tropical and subtropical countries and regions in the world. It was introduced into southern Yunnan from the Sino-Myanmar border in about the 1940s, and is now widely distributed in Yunnan, Guizhou, Sichuan, Chongqing, Guangxi, Tibet and other provinces and regions in the southwest, of which 80% of the land in Yunnan is There is A. chinensis, and it still spreads eastward and northward with the southwesterly wind at a speed of about 30 km per year; ...
