DETAILED DESCRIPTION

[0035] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0036] 1. An artificial golf practice green, which is rectangular in shape as a whole; the artificial golf practice green comprises a lawn mat assembly 1, an artificial lawn 2, and a lawn edge enclosure 3, wherein the artificial lawn 2 and the lawn mat assembly 1 are rectangular in shape as a whole; the artificial lawn 2 is laid on the lawn mat assembly 1, and the lawn mat assembly 1 is composed of a plurality of rectangular lawn mats 1A, which are fixedly connected together; the outer edge of the lawn mat assembly 1 is surrounded and fixedly connected with a lawn edge enclosure so that a golf practice pool A is formed inside the lawn edge enclosure; the laying area of ​​the artificial lawn 2 is equal to or slightly larger than the area of ​​the golf practice pool A, but smaller than the top surface area of ​​the lawn mat assembly 1; the lawn edge enclosure 3 comprises a corner enclosure 3A and a straight edge enclosure 3B; the four corners of the lawn mat assembly 1 are provided with corner enclosures. The enclosure base is fixedly connected to the rectangular lawn mat, and the side length between two adjacent corner enclosure bases 3A is fixedly connected to the rectangular lawn mat by a straight-edge enclosure base 3B; the side length of the rectangular lawn mat is consistent with the length of the straight-edge enclosure base, and the corner enclosure base 3A is closely contacted with the straight-edge enclosure base 3B; the area of ​​the lawn mat assembly 1 increases or decreases according to the number of rows and / or columns of the rectangular lawn mat 1A, and the area required for the corresponding artificial lawn 2 is obtained by cutting according to the area of ​​the lawn mat assembly 1, and the number of corresponding straight-edge enclosure bases 3B used increases or decreases according to the number of rows or columns of the rectangular lawn mat 1A. By increasing or decreasing the number of rows and / or columns of the rectangular lawn mat 1A to change the length and / or width of the lawn mat assembly 1, the overall area of ​​the artificial green for golf practice is changed, thereby changing the area of ​​the golf practice pool.

[0037] For example, the rectangular lawn pad is a square with a side length of 0.3 meters; for example, there are 6 columns of rectangular lawn pads and 6 rows of rectangular lawn pads, and the area of ​​the lawn pad assembly is calculated as: 0.3X6X0.3X6=3.24 square meters; for another example, there are 7 columns of rectangular lawn pads and 5 rows of rectangular lawn pads, and the area of ​​the lawn pad assembly is calculated as: 0.3X7X0.3X5=3.15 square meters; for another example, there are 8 columns of rectangular lawn pads and 10 rows of rectangular lawn pads, and the area of ​​the lawn pad assembly is calculated as: 0.3X8X0.3X10=7.2 square meters; the above examples illustrate that the length and / or width of the lawn pad assembly 1 is changed by changing the number of rows and / or columns of rectangular lawn pads to change the overall area of ​​the artificial green for golf practice; two adjacent straight-edge enclosures 3B are closely connected in contact.

[0038] During production, the manufacturer can produce a number of rectangular lawn mats, corner enclosures, and straight-edge enclosures of the same structure, and then splice lawn mat assemblies 1 of different areas, and then cut artificial lawns 2 of matching areas and lay them on the lawn mat assembly 1, and finally install the corner enclosures and straight-edge enclosures to obtain artificial golf practice greens of different golf practice pool A areas, so that customers can choose the artificial golf practice greens of the required area, and can also be flexibly customized according to the area required by the customer.

[0039] The increase or decrease in the number of straight edge bases 3B refers to the increase or decrease in the side length. The increase or decrease in the number of rectangular lawn mats 1A refers to the increase or decrease in the number of splicing.
