Problems solved by technology
In the past, the windbreak barriers used in the field were large in size and needed to be excavated and buried. The operation was time-consuming and laborious. The shape of the windbreak barriers lacked changes, and it was difficult to adapt to the requirements of field scientific experiments.
[0003] In addition, when taking photos of plants in the field such as plant research, due to the influence of the wind, the branches and leaves of the plants will sway with the wind, and the lens will not be able to focus. The photo is blurred so that it is impossible to discern the morphological characteristics of the plant organs in the photo

The invention relates to field windbreaks provided for desertification control scientific experiments and plant shooting, in particular to a combined type windbreak convenient to carry. The windbreak comprises a first component and a second component; each component comprises an upper frame, a lower frame, stand columns located on two sides of the upper frame and the lower frame, and a wind force speed reduction plate installed in space defined by the upper frame, the lower frame and the stand columns on the two sides in an enclosed mode; lower ends of the stand columns on two sides of the first component are connected with fixing rods inserted into soil, and the stand column on any one side is provided with a groove; the stand column on one side of the second component is provided with a groove, the stand column on the other side of the second component is provided with a plug pin connected with the groove in the first component, the lower end of the stand column provided with the groove of the second component or the lower ends of the stand columns on the two sides are connected with a fixing rod / fixing rods inserted into soil. The windbreak can effectively reduce the wind speed, and is simple in structure, low in production cost, detachable, foldable, convenient to carry and capable of being combined at will according to needs.
Description
technical field [0001] The invention relates to providing a field windproof barrier for desertification control scientific experiments and plant photography, in particular to a portable combined windproof barrier. Background technique [0002] Land desertification has always been one of the biggest environmental problems faced by arid and semi-arid areas in northern my country. The development of land desertification will lead to grassland degradation, vegetation destruction, soil wind erosion, and even the formation of large-scale mobile sand dunes, ecological environment damage, and threats to the safety of human and animal life. Therefore, the goal of desertification control is to use engineering and biological measures to stabilize mobile sand dunes, reduce soil wind erosion, and restore surface vegetation. In areas with severe wind and sand flow, first set up windbreaks to fix the quicksand on the surface, and then use biological measures to restore the surface vegetati...
