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 ecological and environment-friendly herbicide based on sagittaria graminea. The sagittaria graminea is aqueous extract of sagittaria graminea. Gerbera jamesonii is taken as arecipient plant for researching the allelopathy of the aqueous extract of the sagittaria graminea for the recipient plant, it is discovered that different concentrations of the aqueous extract of thesagittaria graminea have different allelopathic effects on germination of Gerbera jamesonii seeds, the aqueous extract with mass concentrations of 0.05 g.mL<-1> and 0.025 g.mL<-1> promotes germination of the Gerbera jamesonii seeds, while the aqueous extract with mass concentrations of 0.1 g.mL<-1> 0.075 g.mL<-1> inhibits germination of the Gerbera jamesonii seeds. By adopting the aqueous extractof sagittaria graminea for eliminating or inhibiting the alien species Gerbera jamesonii, on one hand, invasion of the alien species is inhibited, on the other hand, weed control is realized by the plant preparation, and environmental pollution caused by use of a chemical herbicide and adverse impact caused by herbicide residues are avoided.

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 ...
