Problems solved by technology

However, this device can only be manually stretched and bent when measuring the lodging resistance strength of crops, which is laborious and time-consuming, inconvenient to operate, and is not conducive to multiple measurements; in addition, the device cannot store a large amount of data. And the measured data obtained cannot be transmitted externally

Abstract

The invention discloses a device for measuring crop stem lodging resistance strength and a method for measuring stem lodging resistance strength by using the device. The device includes a force application mechanism, a tensile mechanism, a stem inclination collection mechanism and a stem fixture which is fixed on a crop stem. The force application mechanism comprises a base and a mobile tensile component installed on the base through a hinge; the mobile tensile component includes a tension rod, pedals and a mobile fastening part arranged on the tension rod; and a tension sensor is arranged on the tensile mechanism. The device for measuring crop stem lodging resistance strength can realize storage of a large amount of measured data in measurement of crop stem lodging resistance strength, and can realize the output of the measurement data; and repeated and convenient measurement can be carried out in the measurement of crop stem lodging resistance strength, and stable measurement data can be obtained. The method for measuring crop stem lodging resistance strength can obtain more accurate and reliable tensile strength measurement data in the measurement of crop lodging resistance.

Description

technical field [0001] The invention relates to a strength measuring device, in particular to a device for measuring the lodging resistance strength of crop stalks and a method for measuring the lodging resistance strength of crop stalks using the device. Background technique [0002] Crop lodging is a phenomenon in which the stems of crop plants change from a natural upright state to a permanent dislocation caused by external factors. break off. 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 phenomenon is common in cereal crops such as corn, rice, wheat, soybean, etc. Studies have shown that corn, wheat, rice, tobacco and other crops have huge yield losses due to lodging, and the lodging intensity of crop stalks is a very important indicator that affects crop yields. To determine whether the new crop variety has g...
