Description

Ditching and soil-crushing device of cultivator

Technical Field

The invention belongs to the technical field of agricultural machinery, and particularly relates to a ditching and soil crushing device of a cultivator.

Background

In agricultural production, intertillage, deep scarification and weeding are important farming measures in the field management link of dry farmland. The intertillage is to loosen the earth surface, turn over the soil, eliminate the weeds between the rows and the seedlings, increase the ground temperature, promote the decomposition of organic fertilizer, cut off the capillary of the soil, reduce the evaporation of water and play a role in retaining water and preserving soil moisture. In general, cultivation needs to be carried out for 2-3 times according to different crops and different growth stages. First intertillage: deep scarification (blind pine) before emergence of seedlings has the main functions of deep scarification and cold release, ground temperature increase and seed germination promotion. Generally, a multi-rod-ruler subsoiler is adopted, wherein the front part is shallow and the back part is deep, and the depth is more than 30 cm. The second intertillage is carried out when compound leaves appear, and the effects of increasing the ground temperature, covering soil shallowly and weeding are achieved. And in the later period, three or four intertillage operations are carried out according to the weather conditions.
