Description

Technical Field

[0001] The utility model relates to the technical field of measuring rulers, in particular to a ruler for measuring plant height and plant width. Background Art

[0002] In the process of plant breeding and selection, it is necessary to plant the same batch of seeds and observe the growth characteristics of the plants at the same time. The two most frequently measured data are plant width and plant height. The distance between the two widest branches and leaves is called plant width, and the vertical distance from the ground to the top of the branches and leaves is called plant height. Figure 6 As shown, the collection of these two sets of data can provide important auxiliary analysis data for later breeding and seed selection. At present, the measurement of plant height and plant width between 50-200 cm is mostly measured by measuring tape. This type of measuring tape is prone to rolling up during measurement and has low work efficiency. When measuring plants that are higher than the head, the measurement personnel generally look up when reading the data, which is prone to angle differences, resulting in large degree deviations. When using traditional tools for measurement, it is impossible to measure the plant width and plant height at the same time. The utility model provides a measuring ruler that can measure the plant width and plant height at the same time. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a plant height and plant width measuring ruler to solve the technical problems mentioned in the background technology.

[0004] In order to solve the technical problem, the utility model adopts the following technical solution:

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] refer to Figures 1 to 6 :

[0024] The utility model discloses a plant height and plant width measuring ruler, comprising: a main ruler rod 10, a horizontal ruler rod 20 and a locking screw 30, wherein the main ruler rod 10 is provided with a height scale 101 for measuring the plant height, and one side of the height scale 101 is provided with a plurality of groups of plug holes 11 and a first locking hole 12 distributed in an array along the height direction of the main ruler rod 10, wherein preferably each group of plug holes 11 is two in number, located on both sides of the first locking hole 12, and distributed horizontally, so as to ensure that each group of plug holes 11 and the first locking hole 12 of the horizontal ruler rod 20 and the main ruler rod 10 are perpendicular to each other when fixed, specifically, the spacing between two adjacent groups of plug holes 11 and the first locking hole 12 is preferably 5 cm, and of course, the spacing can also be adjusted to, for example, 1 cm or 2 cm according to the actual required accuracy, when the spacing is 5 cm, if the plant height just falls between two adjacent groups of plug holes 11 and the first locking hole 12, rounding or intermediate engraving can be adopted. Scale estimation, this calculation method can control the error within plus or minus 1 cm. If the spacing is adjusted to 1 cm, the measurement error can be controlled within plus or minus 0.2 cm. The lower end of the main ruler rod 10 is provided with a conical plug 13 for inserting into the soil. The horizontal ruler rod 20 has a retractable multi-section sub-rule rod 201, and the outer side of the multiple sub-rule rods 201 is provided with a width size 21. Specifically, the width size 21 is based on the degree of mutual connection of the sub-rule rods 201 when they are fully unfolded. If the plant is small, there is no need to pull out the sub-rule rods 201 on both sides, and the measurement can be performed using the middle section of the sub-rule rod 201, wherein the sub-rule rod 201 located in the middle section is respectively provided with a plug-in column 22 and a second lock hole 23 relative to the position of the plug-in hole 11 and the first lock hole 12; the locking screw 30 is detachably arranged on one side of the horizontal ruler rod 20, and can pass through the second lock hole 23 to enter the first lock hole 12 and be fixedly connected below the lock hole.

[0025] Specifically, a storage cavity 14 for storing the horizontal ruler rod 20 is provided at the upper end of the main ruler rod 10, and the upper end of the storage cavity 14 is closed by an end cover 15, so that the horizontal ruler rod 20 and other smaller equipment components can be stored in the storage cavity 14 for easy carrying.

[0026] Specifically, in daily use, the soil will be of different softness. It is often easy for the top layer of soil to be hard, so it is inserted downward with great force, while the bottom layer of soil is soft. When the pointed cone plug 13 breaks through the top layer of soil, it will be quickly inserted into the very deep soft soil, which will easily cause the 0 scale of the main ruler 10 to be embedded in the soil, which will affect the measurement of plant height and plant width. Here, a depth limit plate 16 is provided at the end face between the pointed cone plug 13 and the main ruler 10 to locate the depth when the main ruler 10 is inserted into the soil. When the main ruler 10 is inserted deep into the soil with force and just reaches the position of the depth limit plate 16, it can no longer be inserted downward, thereby preventing the main ruler 10 from being over-inserted.

[0027] Specifically, in the measurement of plant width, a problem that often occurs is the estimation of the scales on both sides of the widest part of the plant. Since the growth directions of the branches and leaves at the widest part are different, the visual estimation method will also affect the measurement of the plant width. Here, a plant width extension rod 40 is provided, and the plant width extension rod 40 includes a sliding head 41 that slides with the sub-ruler rod 201 and a hanging part 42 that can be suspended downward. When in use, it is only necessary to slide the sliding head 41 into the sub-ruler rod 201 and slide from the outside to the inside. When the hanging part 42 reaches or sticks to the branches and leaves at the widest part of the plant, read the degree of the sliding head 41 on the sub-ruler rod 201 upwards, which is a more accurate plant width number.

[0028] In order to ensure that the main rod 10 has a horizontal posture when inserted into the soil, a level ruler 17 is further provided at the upper end of the main rod 10 .

[0029] As mentioned above, the extension of the horizontal ruler 20 can be achieved by using a slide rail to limit the extension, or by using an existing extension structure, such as Figure 5 shown.

[0030] The measurement and use methods of the utility model are as follows:

[0031] 1. Plant height measurement: Take out the measuring ruler, take out the horizontal ruler rod 20 and the plant extension rod 40 and other components from the storage cavity 14, and insert the main ruler rod 10 from the pointed cone plug 13 downward to the position close to the main stem of the plant. When it cannot be inserted downward or the bottom soil reaches the depth limit piece 16, observe the horizontal ruler 17 at the top and adjust the main ruler rod 10 to be horizontal. In general, the height of the main ruler rod 10 is higher than the height of the plant. When the main ruler rod 10 is inserted, take out the horizontal ruler rod 20 and observe the position of the first lock hole 12 and the plug hole 11 corresponding to the highest position of the plant. Insert the second locking hole 23 and the plug-in column 22 on the horizontal ruler 20 into the corresponding plug-in hole 11, and then insert the locking screw 30 into the second locking hole 23 and the first locking hole 12 to fix the horizontal ruler 20 on the main ruler 10. At this time, if the highest branches and leaves of the plant are located at the lower end of the horizontal ruler 20, that is, the size degree on the main ruler 10 is the plant height. If the highest branches and leaves are still some distance away from the lower end of the horizontal ruler 20, the horizontal ruler 20 can be moved down a group of positions, or the middle degree can be read, and the degree can be rounded off to record the plant height.

[0032] 2. Plant width measurement. After the plant height is measured as mentioned above, observe the positions of the two branches and leaves at the widest part of the plant, then rotate the main ruler 10, and rotate the direction of the horizontal ruler 20 to be parallel to the line connecting the two branches and leaves at the widest part of the plant. At this time, the degrees of the width dimension 21 of the two branches and leaves can be visually read and recorded as the plant width. In order to read the plant width more accurately, the utility model adds a plant width extension rod 40. The plant width extension rod 40 can be aligned to the position of the two branches and leaves in an upward, downward or forward and backward manner, thereby completing its auxiliary positioning for plant width measurement. It is preferred to move the horizontal ruler 20 upward to the top of the plant, and then let the plant width extension rod 40 hang down. When it just sticks to the two widest branches and leaves, the degree read is the plant width data. Of course, in this way, the main ruler 10 needs to be inserted as close to the middle position of the two widest branches and leaves as possible.

[0033] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
