Abstract

The invention is a quick measuring instrument for crop lodging strength, which mainly includes a digital force measuring device, a dust-proof panel, a ball guide rail, a connecting plate, a rotating positioning plate, a circular scale rod, a ground plug and a special probe. A height scale and a crop center of gravity height gauge are marked on the circular scale rod, which can directly measure the height of the canopy of the measured crop and read the height of the crop center of gravity. There are two arc-shaped positioning grooves on the rotating positioning plate, and the "locking action" of the two positioning screws on the connecting plate by the arc-shaped positioning grooves is used to realize the conversion of the horizontal and vertical measurement positions of the digital force measuring device and "self-alignment positioning". The adjustment of the horizontal height of the digital force measuring device is realized by changing the fixed position of the rotating positioning disc on the circular scale rod. The device can be used for rapid and accurate determination of lodging intensity of single stem and group of wheat, rice, millet and millet.

Description

Technical field [0001] The invention relates to an electromechanical device capable of quickly and accurately measuring the critical breaking strength of wheat, rice, millet and broomcorn stalks, and the lodging resistance strength of a single stalk and a group under different field conditions such as dry land and paddy fields. Background technique [0002] Lodging is a phenomenon in which plant stems change from a natural upright state to a permanent dislocation caused by internal and external factors such as wind, rainfall, and plant stem strength. At present, lodging is still one of the most important limiting factors affecting the high and stable yield of wheat, rice, millet, and millet. Taking wheat production as an example, in 2013, the lodging area of ​​wheat in Shandong Province reached 2.5 million mu and that in Anhui Province reached 1.25 million mu, which had a serious impact on local wheat production. Although there are many ways to prevent crop lodging, breedin...
