[0002] Maize is the largest food crop in China. At present, there are many factors affecting its yield in the process of maize planting. Among them, the problem of maize lodging has become one of the serious obstacles to high-yield maize and mechanical harvesting in China. The three major factors affecting maize lodging are, one is variety, the second is human, and the third is weather. Among them, the too high plant height and ear position of the variety will have a significant impact on maize lodging. Therefore, in the process of maize variety breeding research, a large amount of data collection and statistical analysis of the plant height and ear position height of maize are required. After retrieval, the patent with the application number 201320613121.4 discloses a maize plant height and ear position measuring instrument, which includes: a base; a reference member, which is a telescopic member and is provided with at least one sub-section, and the tail end of its mother section is fixedly connected to one end of the base; a support member, and its bottom end is fixedly connected to the other end of the base; a soft measuring member, and its front end is fixedly connected to the head end of the uppermost sub-section of the reference member; a transition member, one end of which is arranged at the uppermost end of the support member.

[0003] However, during the actual use process, the applicant found that when measuring the maize plant height and ear position, it observes the scale values where the plant height and ear position are located through the naked eye of the personnel. Since the maize plant height is usually higher than the personnel, the method of observing the scale values by looking up with the naked eye of the personnel will make the measurement result inaccurate. In view of this, we propose a maize plant height and ear position measuring instrument. Content of the Utility Model
