Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a soil crushing structure of a cultivator. Background Art

[0002] In agricultural production, intertillage and deep loosening are important farming measures in the field management of dry fields. Intertillage is to loosen the surface, turn the soil, eliminate weeds between rows and seedlings, increase ground temperature, promote the decomposition of organic fertilizers, cut off soil capillaries, reduce water evaporation, and play a role in water storage and moisture conservation. Generally, 2-3 intertillage operations are required according to different crops and different growth stages. The first intertillage: deep loosening (blind loosening) before seedlings emerge, the main function is deep loosening to cool, increase ground temperature, and promote seed germination. Generally, a multi-pole deep loosening machine is used, with shallow loosening at the front and deep loosening at the back, and the depth is more than 30cm. The second intertillage is carried out when compound leaves appear, which has the effect of increasing ground temperature, shallow soil covering, and weeding. In the later stage, three or four intertillage operations are carried out depending on weather conditions.
