Problems solved by technology
However, most of the existing research is to measure the uprooting resistance of corn stalks, and does not involve the maximum moment that the root system can bear when it is stressed from vertical to lodging. At the same time, it is cumbersome to measure the uprooting resistance. The stalks are not easy to clamp, the measurement accuracy is not high, and the complexity and diversity of the field environment and the differences between different varieties of corn stalks will limit the use of the instrument

Embodiment Construction
[0025] Hereinafter, specific embodiments of the present invention will be described in detail in conjunction with the accompanying drawings.
[0026] like figure 1 As shown, the measuring device for measuring the root lodging resistance strength of crop stalks includes: a support frame 12, a driving device, a data acquisition and display device, a rotating pushing device and a steerable wheel component. Wherein the driving device is installed on the supporting frame 12 for driving the rotating pushing device, and the data acquisition and display device is used for collecting and displaying signals such as the speed and angle of the driving device and the rotating pushing device, and the four steerable wheel parts are installed on the supporting frame 12. On both sides of the frame 12, when the measuring device is pushed, the wheels are in a vertical state, and the wheels can be folded to a horizontal state when measuring in the ground, so as to keep the measuring device stable...

The invention discloses a measuring device for measuring root lodging resistance strength of crop stalks. The measuring device comprises a supporting frame, a driving device, a data collecting and displaying device and a rotary pushing device, wherein the driving device is mounted on the supporting frame and used for driving the rotary pushing device, and the data collecting and displaying deviceis used for collecting and displaying speed and angle signals of the driving device and the rotary pushing device; the supporting frame is formed by building aluminum profiles. The measuring device isconvenient to carry, convenient to measure, high in measuring precision and suitable for measuring other crops such as wheat.
Description
technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a measuring device and method for measuring the lodging resistance strength of crop stalk roots. Background technique [0002] With the proposal and practice of corn close-planting cultivation to increase yield, corn lodging has become an important problem that limits the high and stable yield of corn. According to statistics, the light lodging of corn will reduce the yield by 5% to 10%, and the severe one will reduce the yield by 30% to 50%, or even stop production. Maize lodging not only affects the yield and quality of maize, but also is not suitable for mechanized harvesting of maize, which restricts the intensive production of agriculture. [0003] Corn lodging can be divided into root fall, stem fall and stem breakage, among which root fall is most affected by density and causes the most serious yield loss. Root lodging is caused by the destruction of the...
