Description

Technical Field

[0001] The utility model belongs to the field of agricultural planting and relates to a plant lodging resistance measuring device, in particular to a lodging resistance measuring device for plants such as rapeseed. Background Art

[0002] Lodging is mainly caused by the phenomenon of plant rhizomes breaking and irreversible dislocation due to bad weather (such as strong winds and heavy rains). The plant's stems are completely broken due to lodging, and water cannot be transported to the canopy at all. The plant will dry up and die directly due to lack of water; nutrients accumulate in the upper layer, which will cause the main trunk that has stopped branching to increase the number of branches again, but because the plant is difficult to metabolize normally, the new branches only bloom but do not produce fruits. Rapeseed lodging not only has a serious impact on rapeseed yield and grain quality, but also because the plants pile up on each other after lodging, they lose a good spatial arrangement, which causes great inconvenience to manual harvesting or mechanized harvesting. Solving the problem of rapeseed lodging is crucial for breeding lodging-resistant varieties and evaluating resistance. At present, there are many ways to judge the lodging of rapeseed stems. Hideo Seko first proposed a detailed method for measuring the bending resistance of stems (Hideo Seko 1963). Tian Baoming proposed to use the size of the stem coefficient as the basis for distinguishing strong and weak lodging resistance varieties (Tian Baoming 2005). This method mainly combines plant height, stem cross-sectional area, center height and potential energy stationary principle to calculate the stem coefficient. Zhou Guangsheng's method of stem bending resistance has been improved, and it is proposed to calculate the rapeseed lodging index by plant height, stem bending resistance and ground bending resistance (Zhou Guangsheng 2006). Although these methods can evaluate lodging resistance, they require cumbersome experimental operations and cannot be used to measure plant lodging resistance in the field. In addition, the measuring equipment used for these methods is not very portable and is inconvenient to use. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4, the present utility model provides a device for measuring the lodging resistance of plants, which includes a base 1, a support rod 3, a protractor 4 and a linkage member; the support rod 3 and the protractor 4 are both vertically movably arranged on the base 1; the linkage member is on the support rod 3 and moves freely along the axial direction of the support rod 3; a plant placement channel 6 penetrating the base 1 is opened on the base 1 along the thickness direction of the base 1; the axial direction of the plant placement channel 6 is parallel to the axial direction of the support rod 3; the protractor 4 is placed circumferentially around the plant placement channel 6; the plant to be measured is placed in the plant placement channel 6; the linkage member acts on the plant to be measured and drives the plant to be measured to rotate along the plane where the protractor 4 is located.

[0024] Among them, referring to Figure 1 and Figure 3 , the protractor 4 provided by the present utility model includes a main body and a fixed baffle 42 arranged on the main body; the main body is integrally semicircular; scales 41 are arranged radially on the main body; the axial direction of the fixed baffle 42 is perpendicular to the base 1 in a line-plane manner; the support rod 3 is vertically movably arranged on the base 1 and abuts against the fixed baffle 42. Since the axial direction of the fixed baffle 42 is perpendicular to the base 1 in a line-plane manner, when the support rod 3 abuts against the fixed baffle 42, it can be ensured that the axial direction where the support rod 3 is located is perpendicular to the base 1 in a line-plane manner and parallel to the plant to be measured, improving the measurement accuracy. In addition, the protractor 4 further includes a movable baffle 43 movably arranged on the main body and moving freely along the outer contour of the main body. The support rod 3 can be fixed by the movable baffle 43 when it rotates, especially when it reaches the breaking critical point or lodging of the plant to be measured, facilitating the direct acquisition of the lodging angle or the breaking critical angle through the scales 41.

[0025] Referring to Figure 2 , the linkage member includes a connecting seat, a setscrew and a linkage rod 7; the connecting seat is sleeved on the support rod 3 and moves freely up and down along the axial direction of the support rod 3; the linkage rod 7 is fixed on the connecting seat; the setscrew extends from the outside of the connecting seat to the support rod 3; the linkage rod 7 acts on the plant to be measured. Preferably, referring to Figure 1 , Figure 2 and Figure 3 , the linkage member further includes a push-pull force gauge 5 movably arranged on the linkage rod 7; the push-pull force gauge 5 acts on the plant to be measured and drives the plant to be measured to rotate along the plane where the protractor 4 is located. In order to conveniently fix or remove the push-pull force gauge 5 flexibly on the linkage rod 7, the linkage member provided by the present utility model further includes a push-pull force gauge clamp 8; the push-pull force gauge 5 is movably arranged on the linkage rod 7 through the push-pull force gauge clamp 8. The structure of the push-pull force gauge clamp 8 is the same as that of a commercially available mobile phone holder, especially a clamping type mobile phone holder, and will not be elaborated here.

[0026] Referring to Figure 1 and Figure 4, on the upper surface of the base 1 provided by the present utility model, there are provided a protractor storage groove 11 and a support rod storage groove 12. Exemplarily, taking the protractor 4 as an example, the protractor 4 can be stored in the protractor storage groove 11. During use, it can be movably arranged on the base by conventional technical means. After use, the protractor 4 can be directly disassembled and placed in the protractor storage groove 11, enhancing the portability of the present utility model.

[0027] Exemplarily, in order not to occupy more storage space or to enable the support rod 3 to meet the height requirements of different plants, such as corn plants, the support rod 3 provided by the present utility model is telescopic, further expanding the scope of use of the present utility model.

[0028] See Figure 1 , Figure 2 and Figure 3 , the plant lodging resistance measuring device provided by the present utility model further includes a detachable ground-inserting column 2 integrally in a conical shape arranged on the lower surface of the base 1. The detachable ground-inserting column 2 is one or more. When there are multiple detachable ground-inserting columns 2, the multiple detachable ground-inserting columns 2 are evenly distributed on the lower surface of the base 1.

[0029] See Figure 1 , Figure 3 and Figure 4 , the plant retention channel 6 adopted by the present utility model is a groove formed by extending from the outer edge of the base 1 towards the center of the base 1 and penetrating the base 1.

[0030] The plant lodging resistance measuring device provided by the present utility model can be conveniently used for measuring the lodging angle, the fracture critical angle, and the lodging push-pull force.

[0031] For example, when measuring the lodging angle, the lodged plant to be tested (such as rapeseed) is directly placed in the plant retention channel 6, and then the base is inserted into the ground where the lodged plant to be tested (such as rapeseed) is located, and the ground and the base are kept parallel; the support rod 3 is installed on the base 1, and the initial state of the support rod 3 is against the fixed baffle 42 of the protractor 4. At this time, the support rod 3 and the base 1 are in a vertical state, and the lodged plant to be tested (such as rapeseed) is manually lifted up to be straightened. Since there is a linkage rod 7 (linkage rod) on the support rod 3 7 is perpendicular to the axial direction of the support rod 3), so when the plant to be tested (such as rapeseed) that has fallen down touches the linkage rod 7, it is considered that the plant to be tested (such as rapeseed) that has fallen down is in a state perpendicular to the ground surface. At this time, the plant to be tested (such as rapeseed) that has fallen down is released, so that the plant to be tested (such as rapeseed) that has fallen down is naturally lodged again, and the plant to be tested (such as rapeseed) that has fallen down is prompted to rotate along the plane where the protractor 4 is located. The lodging angle of the plant to be tested (such as rapeseed) that has fallen down can be directly read through the scale on the protractor 4.

[0032] When measuring the critical fracture angle, the plant to be tested (such as rapeseed) that has not fallen over is directly placed in the plant retention channel 6, and then the base is inserted into the ground where the plant to be tested (such as rapeseed) that has not fallen over is located, and the ground and the base are kept parallel; the support rod 3 is installed on the base 1, and the initial state of the support rod 3 is against the fixed baffle 42 of the protractor 4. At this time, the support rod 3 and the base 1 are in a vertical state. When the linkage rod 7 on the support rod 3 (the axial direction of the linkage rod 7 is perpendicular to the axial direction of the support rod 3) touches the plant to be tested (such as rapeseed) that has not fallen over, it is considered that the plant to be tested (such as rapeseed) that has not fallen over is in a vertical state. The plant to be tested (such as rapeseed) is already in a state perpendicular to the ground surface. At this time, manual or other external force is applied to the non-lodging plant to be tested (such as rapeseed) to make the non-lodging plant to be tested (such as rapeseed) lean against the movable baffle 43 of the protractor 4, so that the non-lodging plant to be tested (such as rapeseed) is prompted to rotate in the plant retention channel 6 and along the plane where the protractor 4 is located. When the non-lodging plant to be tested (such as rapeseed) is broken, the scale of the protractor 4 is directly read through the movable baffle 43 on the protractor 4, so that the critical fracture angle of the plant to be tested, especially the stem, can be directly read, which is also very convenient to use.

[0033] When measuring the lodging pushing and pulling force, place the unlodged plant to be measured (such as rapeseed) directly in the plant retention channel 6. Subsequently, insert the base into the ground where the unlodged plant to be measured (such as rapeseed) is located, and keep the ground parallel to the base. Install the support rod 3 on the base 1, and make the initial state of the support rod 3 abut against the fixed baffle 42 of the protractor 4. At this time, the support rod 3 and the base 1 are in a vertical state. When the linkage rod 7 on the support rod 3 (the axial direction of the linkage rod 7 is perpendicular to the axial direction of the support rod 3) touches the unlodged plant to be measured (such as rapeseed), it is considered that the unlodged plant to be measured (such as rapeseed) has been in a state perpendicular to the ground surface. Then, install the push-pull force gauge 5 on the push-pull force gauge clamp 8, and fix the push-pull force gauge clamp 8 at an appropriate height position on the support rod 3 according to the height of the plant. The push head of the push-pull force gauge 5 fits against the stem of the unlodged plant to be measured (such as rapeseed). Due to the fixed state of the support rod 3 (inserted on the base 1 and relatively fixed to the base 1), at this time, under the action of the push-pull force gauge 5, the push head of the push-pull force gauge 5 continuously pushes the stem of the unlodged plant to be measured (such as rapeseed) to rotate along the plane where the protractor 4 is located. When the unlodged plant to be measured (such as rapeseed) is at different lodging angles (the scale on the protractor 4 can be directly read), the push-pull force value of the unlodged plant to be measured (such as rapeseed) can be read in real time through the push-pull force gauge 5, which is used as an index to evaluate the lodging resistance of rapeseed.
