Description
Technical field
The present invention relates to duplicate rows no-tillage precision seeders on a kind of ridge suitable for soft stub land block, belong to agricultural mechanical technology
Field.
Background technique
Duplicate rows Mechanization Planting Technology is that soybean is pressed certain spacing in the rows in conjunction with agriculture requirement using mechanical means on soybean ridge
It is sown into soil plough horizon, while realizing a more advanced agricultural machanization new technology of fertilizer deep placement.It is completed at the same time fertilising, sows, cover
A series of operations such as soil, suppression, are a novel cultivation techniques with distinct economic.Saving of labor can be reached, kind is saved, mention
The purpose of high chemical fertilizer utilization ratio and cost-saving synergistic.Soybean yield-increasing amplitude improves chemical fertilizer utilization ratio 10 hundred 15-20% or so
Branch or so.
Sowing structure used by duplicate rows soybean precision planter is generally there are two types of form on the ridge of existing market, one is
Planter uses single-disc colter, and native effect of ditching back is bad.Another kind is exactly that two seeders are gathered together by force,
And open up two seed outlets below plants case and be separately connected two seeders and realize and divide kind, double row sowing is completed, this kind of structure is tight
Waste raw material again, and easily wound kind, the amount of broadcasting is inaccurate, and then leads to the uniformity difference of spacing in the rows and influence the growth of plant, together
When, two seeders generally side by side and flush setting in the prior art, and the disk coulter being arranged thereunder is also side by side
And setting is flushed, when the alley relatively high to soil stickiness is sowed, easily cause during the advance of seeder,
Soil between two disk coulters leads to that " dragging heap " phenomenon occurs, influences thereafter with being entrained in turn before seeder
Earthing operation to kind of ditch.
Summary of the invention
