Rice stalk lodging resistance measuring device

Abstract

The invention provides a rice stalk lodging resistance measuring device, relates to the technical field that materials are tested or analyzed by testing physical properties, and aims to solve the technical problem that multiple indexes of rice stalk cannot be measured in a field. The device comprises a first clamping part, a second clamping part, a tray, a rotating body and a measuring box, wherein a holding part for holding rice stalk is arranged on the first clamping part; an inclination angle sensor and an infrared emitter are respectively correspondingly mounted on both sides of the holding part; the second clamping part is provided with a moveable baffle block which is propped against the rice stalk; the infrared emitter is arranged opposite to one side of the baffle block; both the first clamping part and the second clamping part are rotationally connected with the tray; a pull rod is mounted at an end part of the measuring box; the pull rod is detachably connected with a rotating body; a tension sensor and a tension angle sensor are mounted on the pull rod; the tray is held by hand to rotate the first clamping part and the second clamping part; the outer diameter of the ricestalk is measured by the infrared emitter; the rotating body is rotated, and tension in different angles of the rice stalk can be measured by the pull rod.

Description

technical field [0001] The invention relates to the technical field of testing or analyzing materials by means of measuring physical properties, in particular to a rice stalk lodging resistance measuring device. Background technique [0002] Rice lodging is a phenomenon in which the stems of rice plants change from the natural upright state to the permanent dislocation caused by external factors. Even broken. When this bending force is within a certain range, under natural growth conditions, it can still be restored, but when it exceeds a certain limit, it will cause irreversible damage and form lodging. Lodging can be divided into stem lodging, node lodging and root lodging according to the location where lodging occurs. And most studies show that lodging can be divided into stem lodging (folding) lodging and root lodging. The stem nodes that occur below the panicle can be bent and broken to become stem lodging, and the plant inclination angle greater than 30° or 45°, wh...
