Mechanized sand control equipment and method applicable to plateau regions

Abstract

The invention discloses mechanized sand control equipment and method applicable to plateau regions. The equipment comprises a crawler type mobile platform, a sowing mechanism mounted at the front sideof the crawler type mobile platform and a spraying mechanism mounted at the back side of the crawler type mobile platform, wherein a controller is integrated in the crawler type mobile platform. Themethod comprises the steps: 1. calculating seed depth of sowing; 2. calculating spraying volume per hour; 3. calculating the quantity of refraction type sprayers; 4. mounting dibbling units; 5. mounting the refraction type sprayers; and 6. running the sand control equipment. According to the equipment and the method, through arranging a plurality of dibbers which can move up and down independently, the equipment is applicable to desertification abatement scenes under a variety of operating conditions such as mountains, hills and grassland; and sandy soil of the earth's surface serves as an isolating layer of seeds and a modifier, natural rainfall is employed to dilute the modifier so as to enable the modifier to be in contact with the seeds, a required dilution ratio is achieved, procedures of desertified land abatement operation are reduced, the efficiency of desertification abatement can be greatly increased, the destruction to native pasture is minimized, and operations are mechanized.

Description

technical field [0001] The invention belongs to the technical field of mechanized sand control, and in particular relates to a mechanized sand control device and method suitable for plateau areas. Background technique [0002] Land desertification refers to the phenomenon that due to soil erosion, the surface soil loses fine particles (silt, clay) and gradually becomes sandy, or due to the invasion of quicksand (sediment), the organic matter content of the land decreases, and the productivity decreases or even loses. The control method is mainly to restore the original ecology by improving the sand aggregate, increasing organic matter, and planting plants. [0003] The commonly used methods to control land desertification include enclosure and natural recovery, grass grids for sand-fixing and grass planting, and liquid mulch, all of which have good control effects. The main problem of desertification control is the high cost, of which labor costs account for a large proport...

AI Technical Summary

Problems solved by technology

The main problem of desertification control is the high cost, of which labor costs account for a large proportion. Soil remediation, organic matter improvement, sowing, fertilization and other work must be completed according to the process. Each process requires human intervention, which leads to an increase in the overall control cost. It has become a bottleneck restricting the work of land desertification control

[0004] Sandy land can generally be divided into: mobile sandy land, fixed sandy land, semi-fixed sandy land, dew sandy land, and wind-eroded sandy land. There are some native plants on most of the sandy land. Restoration is carried out on the terrain, and the existing agricultural machinery is developed for the leveled cultivated land, which is difficult to adapt to the undulating special terrain of the plateau sandy land, and the plateau sandy land is often located in the middle of the mountain, slopes, and hills, and it is difficult to dilute the amendment with water Obtained, resulting in high construction costs, plateau desertification areas, such as: Ruoergai, Sanjiangyuan and other places, although the land is desertified, but there is no lack of precipitation in the local area, the annual average precipitation of Zoige is about 650 mm, and the Sanjiangyuan area is 289-749 mm, 6 More monthly precipitation
