The invention belongs to the technical field of ecological environment restoration, and particularly relates to an arid region gobi gravel curtain layer reconstruction method. Gobi in the arid region is subjected to earth surface leveling, gravel layer paving and saline pressing in sequence, and a gravel curtain layer is obtained. The gravel curtain layer earth surface reconstructed through the method has no obvious landscape difference with the surrounding natural gravel curtain layer earth surface, salt crust and gravel are tightly bonded together to form a hard soil protection layer, the earth surface can be effectively solidified, and soil wind erosion can be resisted.

This invention discloses an unmanned tracked robot for agricultural sowing, relating to the field of agricultural machinery technology. It includes an unmanned tracked sowing vehicle with a trapezoidal block fixedly connected to its top. A fixed horizontal plate is fixedly connected to the side wall of the trapezoidal block, and a centrifugal sowing component is mounted on the top of the fixed horizontal plate. The centrifugal sowing component includes a stepper motor fixedly connected to the side wall of the trapezoidal block. The centrifugal sowing component utilizes centrifugal force to throw seeds from the sowing device, causing the seeds to disperse evenly within a certain range. This avoids excessive concentration or uneven distribution of seeds, ensuring uniform seed distribution in the field and promoting uniform crop growth. The centrifugal sowing device can perform sowing operations at a high speed, significantly improving sowing speed compared to traditional manual sowing or some low-speed sowing methods. It can complete large-area sowing tasks in a short time, making it particularly suitable for large-scale agricultural production and effectively shortening the sowing cycle.
