Abstract

The invention discloses a device for measuring the pull-down force of the root of a rod-shaped plant, and an application method of the device. The invention aims at solving problems that there is short of a root lodging resistance measurement device of the rod-shaped plant in the prior art and an error of a manual measurement result is big. The device comprises an upper soft device fixing sleeve, a lower soft device fixing sleeve, a central hard connection sleeve, and a force meter which is vertically connected with the external surface of the central hard connection sleeve. The application method comprises the steps: 1, keeping a plant stalk 30-130 cm higher than the ground surface, removing all other parts, and determining the setting height of the force meter; 2, carrying out the sleeving installation of the lower and upper soft device fixing sleeves and setting the central hard connection sleeve; 3, vertically connecting the force meter; 4, pushing the force meter, wherein the maximum fore displayed by the force meter serves as the pull-down force of the root of the rod-shaped plant. The device and method enable the success rate to be 98%, are suitable for the rod-shaped plants, and are accurate. The device and method are suitable for the measurement of the pull-down forces of the roots of the rod-shaped plants.

Description

Technical field: [0001] The invention relates to a device for measuring the push-down force of rod-shaped plant roots and its application method. Background technique: [0002] In order to measure the strength of root lodging resistance of rod-shaped plants, the method of artificially simulating root lodging is usually used. During operation, keep the middle and lower part of the plant, remove the parts other than the middle and lower part of the plant, and then push the plant stem with a dynamometer in a direction perpendicular to the plant stalk, and the plant stalk and the dynamometer are perpendicular to each other at 90°. °. During operation, the vertical state between the plant stem and the dynamometer should be maintained until the desired result of the test is obtained. But in actual operation, the tip of the dynamometer is attached to the surface of the stalk. Since the tip of the dynamometer is usually a flat surface and the stalk is cylindrical in shape, the co...
