Embodiment 1

[0024] Embodiment 1, plant vertical uprooting resistance value detector

[0025] figure 1 A schematic diagram of the appearance structure of the plant vertical uprooting resistance value detector provided by the present invention, the instrument is composed of a mechanism part and a measurement display part; wherein, the mechanism part includes a bracket, a clamp and a screw mechanism; the bracket includes a hand wheel 12 The clamp includes jaws 7; the screw mechanism includes a disc 15 and a screw 19 located under the handwheel 12; The screw rod 19 is connected; the measurement display part includes a tension sensor 20 and a display instrument 21; the tension sensor is located between the screw rod 19 and the clamp 22; the display instrument is located between the disc 15 and the between the screws 19.

[0026] figure 2 It is a structural cross-sectional view of the legs of the bracket, which is composed of a bracket mounting part 1, a bracket rod part 2, a ring screw 3, ...

Embodiment 2

[0029] Embodiment 2, detecting the vertical uprooting resistance value of straw plants

[0030] Cut off a part of the straw first, keep only about 20 cm above the ground, clamp the straw with the clamp, turn on the switch of the liquid crystal display controller, and turn the hand counterclockwise when the wire rope is not tightened (if it has been tightened, wheel until the wire rope is loosened) to manually reset, turn the hand wheel 12 clockwise to drive the screw rod 19 to rise, and the screw rod 19 drives the clamp to rise through the tension sensor 20, and when it rises to a certain degree, the plant can be pulled out by the roots. During the rooting process, the tension sensor picks up the tension signal, and after routine processing by the liquid crystal display controller, the measured real-time value is displayed, which is the vertical uprooting resistance value of the straw plant to be tested, and the measured straw plant is completed. Detection of straw root fall s...

Abstract

The invention discloses a method and special detector for detecting vertical uprooting resistance value of plants. The detector comprises a mechanism part and a measurement and display part, wherein the mechanism part comprises a support, a jig and a screw mechanism; the support comprises a hand wheel; the jig comprises a clamping jaw; the screw mechanism comprises a disk and a screw stem which are arranged below the hand wheel; the disk is connected with the screw stem through a disk accessory matched with the screw stem; the measurement and display part comprises a tension sensor and an indicator; the tension sensor is arranged between the screw stem and the jig; and the indicator is arranged between the disk and the screw stem. The detection method comprises the following steps: clamping and pulling out the plant with the above detector for detecting vertical uprooting resistance value of plants, collecting a tension signal by the tension sensor, and reading an instantaneous value of the tension signal by the indicator, namely the vertical uprooting resistance value of plants. The detector of the invention has low hardware cost, friendly man-machine interface, popularization performance in economically and good application prospects, and is reliable and portable.

Description

technical field [0001] The invention belongs to the field of agricultural engineering and relates to a method for detecting the vertical uprooting resistance value of plants and a special detector thereof. Background technique [0002] Corn is one of the main production lines of major food crops in the world, and it is closely related to people's survival. In my country, the annual corn planting area has reached about 28 million hectares, and the annual corn production has reached 160 million tons. The planting area and corn production are both in the second place in the world. However, compared with other agricultural developed countries in the world, my country's corn yield is still at the middle level. Therefore, relying on agricultural technology and striving to increase the yield of corn per unit area will be the main trend of my country's future corn production. For corn production, corn lodging is one of the important factors affecting its yield. According to statist...
