A herbicidal powder prepared from waste after extraction of camphor tree essential oil and application thereof

Abstract

The application discloses a herbicide powder prepared from waste after extraction of camphor tree essential oil and application thereof, and relates to the technical field of biological weeding. The herbicide powder prepared from waste after extraction of camphor tree essential oil is prepared into a weeding liquid, when the concentration of the weeding liquid reaches 5g / L, the germination of bidens pilosa is significantly inhibited; when the concentration of the weeding liquid reaches 3.75g / L or above, the growth of the barnyard grass is effectively inhibited, when the concentration of the weeding liquid is 5.00g / L, the plant height, fresh weight and root length of the barnyard grass are only 15.2%, 0.6% and 7.1% of those of the CK group respectively; when the concentration of the weeding liquid is 4g / L, the coverage of white clover in the test area is about 13%, only 14.7% of that in the control area. The application provides a novel green biological weeding technology, and meanwhile realizes efficient utilization of waste after extraction of camphor tree essential oil.
