Description
Technical field
The present invention relates to a kind of sound piece differential speed type single-grain precision seeding apparatus, are the dresses for agricultural machinery precise sowing
It puts, belongs to agricultural machinery technological field.
Background technology
Precise sowing refers to, by accurate grain number, spacing and seed level, seed is sown into soil.It can be monoseeding,
Seed more than one can also be broadcast into a cave, it is desired to equal per seed number per.Precise sowing can save seed, and between being not required to
Seedling reduces the supply of fertilizer, and with common drilling ratio, seed is evenly distributed in the line, and crop daylighting is more preferably thus conducive to crop
Growth, yield can be improved.
In recent years, the continuous development of breeding, seed working process technology, pesticide, herbicide and water conservancy irrigation technology with it is complete
Kind, the germination percentage and survival rate of seedlings for making seed have certain guarantee, and precise sowing technology is made to have more reliable guarantee, simple grain essence
It broadcasts and is widely applied in foreign countries.
In China, the R and D of precise sowing technology start from the beginning of the seventies, so far there are no being widely used,
Main cause is no suitable precision metering device component.In recent years, China was concentrated mainly on the research of single grain fine sowing feed mechanism for seed
