Description

Technical Field

[0001] This utility model relates to the field of seedling quantity statistics technology, and in particular to an auxiliary tool for seedling quantity statistics. Background Technology

[0002] This technology primarily targets wheat seedling quantity statistics, but can also be applied to the quantity statistics of other plant seedlings. The core purpose of wheat seedling quantity statistics is to scientifically assess field emergence quality, optimize population structure, and guide precision management. Wheat seedling quantity statistics are specifically divided into the following five dimensions: diagnosing emergence quality, optimizing population structure, guiding water and fertilizer management, predicting yield potential, and scientific research and variety evaluation. Specifically, in diagnosing emergence quality, the effectiveness of sowing is verified by comparing the actual number of seedlings with the theoretical sowing rate (e.g., 10,000 seedlings per kilogram) to determine whether sowing depth and uniformity meet standards. In optimizing population structure, the basic seedling count is determined by statistically analyzing the number of seedlings per unit area (e.g., 10,000 plants / acre) to determine whether the target population has been reached (e.g., 150,000-250,000 plants / acre is required for winter wheat). Therefore, wheat seedling quantity statistics are particularly important.

[0003] Currently, the main methods for counting wheat seedlings in existing technologies include: manual field counting, image processing, UAV remote sensing inversion, and portable equipment-assisted methods. Manual field counting involves selecting representative sample points in the field (such as the "five-point sampling method"), measuring the number of seedlings in fixed row lengths (such as 1-meter double rows), and combining the row spacing to calculate the number of seedlings per unit area. This method is suitable for small fields or experimental fields requiring high precision, but it is time-consuming, labor-intensive, and prone to omissions or duplicates. Image processing involves taking field images with a UAV or mobile phone, extracting wheat seedlings using green channel threshold segmentation, identifying adherent seedlings through connected region area comparison, and then automatically counting them; however, its equipment investment is high. UAV remote sensing inversion is prone to seedling swaying during image acquisition, and its subsequent image processing is complex. Portable equipment-assisted methods use 1m... 2 Using wire frames (for broadcast seeding) or 50cm rulers (for strip seeding) to quickly delineate quadrats, and then manually counting the seedlings to calculate the number of seedlings per acre, is relatively convenient. However, as the seedlings grow, the dividing lines of the wire frames or 50cm rulers cannot be clearly shown, and problems such as omissions or duplicates are also prone to occur.

[0004] Therefore, there is an urgent need to develop a simple and statistically reliable tool for counting seedlings. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide an auxiliary tool for seedling quantity counting. The technical solution adopted by this utility model is as follows:

[0006] A seedling number counting aid is placed in a field where the number of seedlings to be counted. It includes a lower support frame pre-buried in the field where the number of seedlings to be counted, several support cylinders arranged on the lower support frame and along the longitudinal direction, uprights that are installed through the support cylinders one by one, and a counting net fitted on the uprights and adjusted up and down along the longitudinal direction; the counting net is provided with several counting grids of the same size; the lower support frame is rectangular.

[0007] Furthermore, the support cylinder is disposed on the rectangular apex corner of the lower support frame, and three or four support cylinders are configured.

[0008] Furthermore, the column has several support grooves along the longitudinal direction; the counting net is fitted onto the support grooves.

[0009] Furthermore, the column has several through holes along the longitudinal direction; a pin is provided in each through hole; and the counting net is placed on the pin.

[0010] Furthermore, the size of the counting grid is 0.25m × 0.25m.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) This utility model ensures reliable installation of the column and reliable support of the counting net by setting up a rectangular lower support frame and support cylinder. In addition, this utility model uses the column for longitudinal support to facilitate adjustment of the counting net in the longitudinal direction.

[0013] (2) The present invention provides a support groove or through hole in the column, and adjusts the position of the counting net according to the height of the seedling, so as to make the counting net easy to be adjusted to a position that is convenient for manual counting, thus ensuring the reliability of the statistics.

[0014] In summary, this utility model has the advantages of simple structure and reliable statistics, and has high practical and promotional value in the field of seedling quantity statistics technology. Attached Figure Description
