Description

A kind of sead feeder being applicable to two kinds of crop colleague's catch cropping

Technical field

The present invention relates to a kind of sead feeder being applicable to two kinds of crop colleague's catch cropping, belong to agricultural seeder machinery technical field.

Background technology

Intercropping refers to the space structure principle using crop community, two or more crop carries out the Agriculture Production Modes planted on same plot, also referred to as three-dimensional agriculture according to the width ratio of certain row, spacing in the rows and occupation of land. Plant type height is differed, crop that period of duration length is slightly irregular carries out reasonably combined, can improve the utilization rate of luminous energy, soil and aboveground space, is favorably improved intercropping effect, promotes agricultural production and income. Generally several crop same times sowing cry catch cropping, different times sow cry interplanting. Intercropping can reasonable disposition crop groups, make crop height stratification, alternate embark on journey, have adjusted Field structure, become nonoculture top planes and use up and alternately use up into layering, timesharing, be conducive to improving the ventilation of crop, light transmission condition; Meanwhile, two kinds of crop interplanting interplantings also can produce complementary action, for instance pulse family and grass family catch cropping are conducive to supplementing the consumption of Soil Nitrogen element.

With the development of mechanization of agriculture seeding technique, it is contemplated that the needs of later stage mechanized harvest, it is currently all carry out in the way of " different rows catch cropping " for the Mechanization sowing of two or more crop. Such as, the existing corn soybean catch cropping sowing of China mainly has 7+1 pattern (7 row Soybean Intercropping 1 row Semen Maydis), 12+2 pattern (12 row Soybean Intercropping 2 row Semen Maydis), 2+2 pattern (2 row Soybean Intercropping 2 row Semen Maydis) etc. And there is not yet and carry out, for two or more crop, the report that mechanization " colleague's catch cropping " is sowed, the sowing of two or more crop of namely hocketing in same Mechanization sowing row.

Under the new situation, two or more crop is carried out mechanization " colleague's catch cropping " sowing and still has its research and development necessity and the market demand: (1) is compared with " different rows catch cropping ", " colleague's catch cropping " is more conducive to ventilation and the printing opacity of field multiple directions, the ventilation of crop, light transmission condition better, thus are more conducive to the growth of crop under equal conditions;(2) " colleague's catch cropping " for ventilating, the bad industrialized agriculture booth of lighting conditions, cheuch plot etc. especially suitable; (3) compared with " different rows catch cropping ", " colleague's catch cropping " spatially makes the crop with tonification effect closer, thus is more conducive to play its tonification effect; (4) " colleague's catch cropping " be non-fully unfavorable for mechanized harvest, when breeding season not close (long-stalked crop first bar crop after-ripening ripe, low), it is possible to overcome mechanized harvest problem by suitably adjusting the harvesting parameter such as harvesting height, harvesting speed.
