Description

Technical Field

[0001] The utility model belongs to the technical field of seedling investigation, and in particular relates to a seedling investigation plot device. Background Art

[0002] The standard plot method is also known as the sample plot survey. In the seedling production area to be surveyed, a small sample plot with an area of ​​one to five meters is selected at a certain distance as the standard plot, and the seedlings are surveyed one by one on the standard plot. This method is suitable for seedling surveys produced by broadcast seedling cultivation.

[0003] In the Chinese patent with the announcement number CN208671902U, a forest community sample plot survey device is mentioned. The tool includes: four rods, one end of each rod is a conical structure, and the other end is a hollow structure. Each rod also includes a telescopic device and a hanging buckle. The telescopic device is installed inside the hollow structure of the rod, and the hanging buckle is installed outside the hollow structure of the rod; four sample plot ropes, one end of each sample plot rope is connected to a telescopic device, and the other end includes a hook, each hook is connected to a hanging buckle, and each sample plot rope includes a scale; the four rods are the four vertices of the sample plot, and the four sample plot ropes are the four sides of the sample plot. In this way, sample plot surveys can be carried out more conveniently.

[0004] However, the above technical solution uses four rods as the four vertices of the sample plot and four sample ropes as the four sides of the sample plot, so that the sample plot survey can be carried out more conveniently. Although this device can circle the position of the sample plot, the sample rope is relatively soft, the position of the sample plot is prone to change, and it is difficult to connect and support the four columns, resulting in the four rods being easy to tip over, so it needs to be improved by the staff.
