Embodiment Construction

[0019] The present invention will be described below through specific examples, but the present invention is not limited thereto.

[0020] The experimental methods used in the following examples are conventional methods unless otherwise specified; the reagents and materials used in the following examples can be obtained from commercial sources unless otherwise specified.

[0021] 1 Materials and methods

[0022] 1.1 Test materials

[0023] The air-dried specimens of Sagittarius graminearum and the seeds of the recipient plant Gerbera came from the College of Life Sciences, Changchun Normal University.

[0024] 1.2 Research Methods

[0025] 1.2.1 Preparation of extract solution

[0026] In this experiment, the allelopathic effect of the roots and leaves of Arthia chinensis was studied. Take a well-developed Sagittarius graminosa specimen, air-dry it completely at room temperature, cut it into pieces with scissors, weigh 25g, add 250mL distilled water to soak at room tempera...

Abstract

The invention provides an eco-friendly herbicide based on Sagittarius graminosa and its preparation and application. Heye Arrowhead is the water extract of Heye Arrowhead. The present invention selects gerbera as the recipient plant, studies the allelopathic effect of Sagittarius graminearum water extract on the recipient plant, and finds that the allelopathic effects of different concentrations of Sagittarius graminearum water extract on germination of gerbera chrysanthemum seeds are different, and the mass concentration is 0.05 g·mL ‑1 , 0.025g·mL ‑1 The water extract of gerbera has a promoting effect on the germination of gerbera seeds, and the mass concentration is 0.1g·mL ‑1 , 0.075g·mL ‑1 The water extract of gerbera chrysanthemum seed germination showed inhibitory effect. Using Arthia chinensis water extract to eliminate or inhibit the alien species of gerbera, on the one hand to curb the invasion of alien species, on the other hand to weed with plant preparations, to avoid the environmental pollution caused by chemical herbicides and the negative effects of drug residues influences.

Description

technical field [0001] The invention belongs to the technical field of herbicides, and in particular relates to an eco-friendly herbicide based on Sagittarius graminosa and its preparation and application. Background technique [0002] Allelopathy, also known as heterogeneity, refers to the fact that one plant affects the growth of other plants by secreting chemical substances in the metabolic process outside the body. This effect is a special form of species survival struggle, and both intra-specific and inter-specific relationships have allelopathic effects. The allelopathic effect between plants is a hot spot in the current chemical ecology research. Specifically, it refers to the release of chemical substances from donor plants to the environment through the volatilization of stems and leaves, leaching, litter decomposition, root secretion, etc., thereby Promote or inhibit the growth and development of surrounding plants. Plant allelopathy exists widely in nature, and ...
