Problems solved by technology

However, there are still many aromatic plants whose allelopathic and herb-inhibiting effects have not been reported, so there is a lot of research space for aromatic plants in the resource selection of weed suppression

Embodiment 1

[0012] 1. Preparation of pure allelochemicals and mixed component solutions

[0013] According to the measured contents of the 5 kinds of allelochemicals detected in the basil water extract, the allelochemicals were made into the following concentrations. A: o-coumaric acid: 5 μmol / L; B: caffeic acid: 0.4 μmol / L; C: vanillin: 3 μmol / L; D: salicylic acid: 9 μmol / L; E: geraniol: 54 μmol / L, And 5 kinds of allelochemicals are freely combined according to their respective concentrations, and finally the solutions containing 1 component, 2 components, 3 components, 4 components and 5 components of allelochemical substances and mixed components are respectively obtained. , a total of 31 treatments.

[0014] 2. Treatment of recipient seeds

[0015] Choose plump and uniform gray vegetable seeds, sterilize with 5% NaClO for 3-5 minutes, rinse with tap water for several times, and finally rinse with distilled water for 3-5 times for later use.

[0016] 3. Detection of biological effec...

Abstract

The invention provides a method for inhibiting the growth of weed roots. The method for inhibiting the growth of weed roots provided by the invention comprises administering effective doses of vanillin and salicylic acid. According to the present invention, the seeds of Prunus argyi are treated with different combinations of five allelopathic components, and it is found that the mixed components of vanillin and salicylic acid have the strongest inhibitory effect on the root growth of Prunus officinalis in hydroponic culture, and the inhibition rate reaches 50% compared with the control . Compared with the inhibitory effect of a single component on the root growth of ash, the combination of the two has an obvious gain effect. It shows that vanillin and salicylic acid have broad application prospects in controlling weeds, especially dicotyledonous weeds.

Description

technical field [0001] The invention belongs to the field of plant allelopathy, and in particular relates to a method for inhibiting the growth of weed roots. Background technique [0002] Weeds in farmland bring harm to the growth and development of crops, and the extensive use of chemical herbicides will lead to very serious problems of food security and environmental pollution. The allelopathy of plants refers to the relationship between plants and environmental species through the release of secondary metabolites. Studies have shown that some species can inhibit the germination and growth of companion species by releasing allelochemicals. Using allelopathy to control weeds is to develop biopesticides on the basis of studying the mutual inhibition mechanism between species in nature, so as to realize the biological control of weeds. It is a safe and safe weed control method worth exploring. [0003] Aromatic plants are a kind of biological group with strong secondary me...
