本研究在测定苦荞麦发育特性的基础上，研究了苦荞麦种植区常见的恶性杂草土

In this study, on the basis of determining the developmental characteristics of tartary buckwheat, the activity and viscosity of tartary buckwheat root marginal cells under the action of water extracts of the common malignant weeds schizonepeta, spicy grass, and cloverweed were studied The thickness of the glue layer, the mitochondrial membrane potential, and the changes of ROS and NO levels were designed to understand the allelopathy mechanism of weeds in different farmland of tartary buckwheat planting area, and provide a theoretical basis for weed control in tartary buckwheat farmland.

On the basis of determining the development characteristics of bitter buckwheat, this study studies the influence of the malignant weeds, spicy grass, three-leaf ghost grass water-soaked liquid, the activity of the edge cell of bitter buckwheat root, the thickness of the mucosa layer, the mitochondrial membrane iotin and the change of THE ROS and NO levels, and aims to understand the mechanism of the chemical effect of different farmlandwes in the bitter buckwheat growing area, and provide a theoretical basis for the control of weeds in the bitter buckwheat growing area.

Based on the determination of development characteristics of tartary buckwheat, the changes of limbic cell activity, mucilage layer thickness, mitochondrial membrane potential, ROS and no levels of common malignant weeds in the cultivation area of tartary buckwheat were studied under the action of water extracts of soil Schizonepeta, horseradish grass and Bidens triloba, in order to understand the Allelopathy Mechanism of different farmland weeds in the cultivation area of tartary buckwheat To provide theoretical basis for weed control in wheat field.
