Description
Technical Field
The invention relates to the technical field of agricultural machinery, in particular to a reclamation device for agricultural yellow land.
background
China is the largest agricultural country in the world, and the agricultural cultivated land in early stage reaches 20.24 hundred million acres. However, in recent years, the cultivated land area of China is gradually reduced, and the main reason is that the urban construction is accelerated, and a large amount of cultivated land area is occupied, so more non-agricultural land needs to be reclaimed for supplement. Among them, since the yellow lands are seriously deficient in mineral elements for plant growth, and agricultural products cannot be planted, a large amount of chemical fertilizers should be applied to improve the soil during the yellow land reclamation process.
In the existing land reclamation process, a colter on a reclaimer is used for loosening the land, and then chemical fertilizer is applied to the loosened soil, but the applied chemical fertilizer can only be spread on the surface and is easy to run off along with rainwater. In view of the problem that the chemical fertilizer is easy to run off during the reclamation process, people can dig a pit in the reclaimed land, bury the chemical fertilizer in the pit, and finally cover the dug soil in the pit. Although the process of the reclamation realizes the reclamation and the fertilization, and the fertilizer is not easy to run off along with rainwater, the four steps of the reclamation, the digging, the fertilization and the covering are required, the period of the reclamation process is greatly increased, and the labor productivity is increased. Therefore, the invention provides a reclamation device which can realize reclamation and fertilization and can prevent the fertilizer from running off, aiming at the defects of the existing reclamation machine in the reclamation of the yellow land, and the technical problem to be solved.
