Vibration spacer scarifier

technical field

Background technique

my country is a traditional large agricultural country with a large area of arable land. The common plow is widely used in farming to plow and loosen the soil. However, there are various disadvantages in plowing. After plowing, the soil surface is too loose, and a lot of water and water are lost. Nutrients and organic matter in the soil are seriously lost. Tilling consumes a lot of power and high operating costs, which not only compacts the soil, but more importantly forms a hard plow bottom. The existence of the bottom layer of the plow reduces the gaps in the soil, resulting in a decrease in the water permeability and air permeability of the soil, which causes the bottom layer of the plow to block the infiltration of precipitation when it rains, resulting in serious water and soil loss or erosion. Subsoil water is supplied upwards for crop growth. In addition, due to the existence of the bottom layer of the plow, the root system of the crops cannot be pierced through, but can only grow in curls above the bottom layer of the plow.

Interval loosening is a farming technique that uses the coexistence of virtual and real to make the soil form two parts of "virtual" and "real" after operation. The imaginary part is produced by loose soil parts. The soil is loose, the porosity is large, and the air permeability is good, so that the surface water can quickly seep to the bottom layer, reduce surface runoff, increase the ability of water storage and moisture retention, and form a "soil reservoir", which is beneficial to microorganisms. Propagate and promote soil decomposition to form available nutrients. The real part is the unturned part of the soil, which maintains the capillary void state of the surface covering, soil aggregates and structural integrity, so the soil porosity is small, the water and nutrients are evenly distributed in the capillary tubes, the transpiration is fast, and the temperature change is gentle, which is convenient for the root development of crops , and conducive to the reproduction of anaerobic microorganisms, increase the content of organic matter, facilitate the maintenance of long-term nutrients, increase fertility, and increase the stamina of crop growth.

Vibration interval loosening can not only effectively reduce power consumption, but also make the gap between the void and the solid part of the soil differ by more than 10%, resulting in the coexistence effect of virtual and solid parts. At the same time, the empty channel at the bottom forms an effective water and fertilizer reservoir for crop growth.
