Embodiment Construction

[0012] In order to make the content of the present invention easier to understand, the technical solutions of the present invention will be further described below in conjunction with specific embodiments, but the present invention is not limited thereto.

[0013] barnyardgrass used ( Echinochloa crusgalli (L.) Beauv) seeds were collected in the field experiment field of Fujian Agriculture and Forestry University and kept for one year.

[0014] The macroporous adsorption resins ADS8 (non-polar resin) and ADS21 (polar resin) were purchased from Nankai University.

[0015] 1. Acquisition of Inducing Substances

[0016] 1.1 Collection of barnyardgrass planting solution

[0017] Select full-grained barnyardgrass seeds, disinfect them with 0.5wt% sodium hypochlorite solution for 10 minutes, rinse them with distilled water, and spread the seeds on a sand tray (the sand is pre-sterilized at 65°C for 30 minutes, and then repeated 3 times after cooling), adding Cover with a proper ...

Abstract

The invention discloses inductive substances for improving rice allelopathy extracted from a secretion solution of barnyard grass. Adsorption separation of the secretion solution of barnyard grass is achieved by macroporous resins ADS8 and the inductive substances for improving rice allelopathy are obtained. The inductive substances are non-polar combinations including amides, indole compounds, phenolic compounds, pahs compounds and alcohol compounds. The inductive substances have the advantage of that the rice allelopathy is significantly increased.

Description

technical field [0001] The invention specifically relates to an inducing substance extracted from barnyardgrass planting liquid and capable of improving rice allelopathic effect, belonging to the field of agricultural ecology. Background technique [0002] Induced systemic resistance (ISR) is a phenomenon that widely exists in the plant world. In addition to using artificially synthesized substances to induce plants to increase stress resistance, the use of plant-derived substances can also induce other plants to enhance stress resistance. Barnyardgrass is an associated weed of rice. It not only secretes plant hormones, but also produces various plant signal molecules, which induce rice to enhance allelopathy. Studies have shown that rice allelopathy is enhanced in the presence of barnyardgrass, suggesting that there may be chemical communication between rice and barnyardgrass to sense each other's presence. However, the chemical communication substances between the two par...
