Description
Technical field
The utility model belongs to paddy rice cross breeding seeding technique field, particularly relates to a kind of adjustable water rice hybridization production of hybrid seeds supplementary pollination mechanical device.
Background technology
The self pollination crop that paddy rice is strict, natural hybrization rate is generally between 0.2～4%, the highlyest also just reach 5%, therefore realize hybrid seeding and must carry out alienation pollination, pollen grain on male parent stamen is fallen on the column cap of maternal gynoecium, the fruit of bearing so just may keep the merit of male parent, grows into the hybrid rice seeds of high-quality, high yield.Therefore only relying on spontaneous pollination is the production requirement that cannot meet hybrid seeding, must adopt supplementary pollination, just can reach the requirement of at least 3 pollen on each pistil stigma, guarantees the normally solid of hybrid seed.
Conventionally way is that two people stand opposite respectively on ridge at present, respectively draw one end of a hawser, staminiferous plant is pulled to female plant, thereby the pollen dispersed on staminiferous plant is fallen on the column cap of gynoecium, be commonly called as " garland ", in garland process, because the paddy rice development time is shorter, therefore require walking fast, the enough pollination fabric widths of guarantee like this, once pollination needs to wait for that pistil just can carry out repetition garland while continuing opening after finishing, until the density of the pollen on pistil column cap reaches certain requirement, not only efficiency is slow for above-mentioned supplementary pollination method, labour intensity is larger, and pollination non-uniform phenomenon is comparatively obvious, thereby cause hybrid seed yield lower.
Summary of the invention
The utility model for solve the technical problem existing in known technology provide a kind of simple in structure, easy to use, increase work efficiency and the adjustable water rice hybridization production of hybrid seeds supplementary pollination mechanical device of pollination rate.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
A kind of adjustable water rice hybridization production of hybrid seeds supplementary pollination mechanical device, is characterized in that: comprise crossbeam, a side of described crossbeam is symmetrically welded with the engaging lug being connected with motor vehicle afer bay, is coated with connecting pin in engaging lug; One end of described crossbeam is welded with bracket, two parallel risers are installed on described bracket, between two risers, by spring bearing, wind-up roll are installed, on described wind-up roll, coiling has hawser, outer end at spring bearing is provided with gland, on described wind-up roll, crank is installed; The other end of described crossbeam is provided with thread segment, on described thread segment, be fitted with locking nut, the leading section of described thread segment is provided with polished rod, on described polished rod, be welded with spacing back-up ring, on described polished rod, be set with rotary sleeve, the lower end of described rotary sleeve is welded with two connecting plates, between two connecting plates, be fitted with swing arm, between described swing arm and connecting plate, be provided with lock-screw, the top of described rotary sleeve is provided with marks closely screw, described marking closely in screw is equipped with and marks closely screw, and the outside in described swing arm is welded with trussed shore; The upper surface of described crossbeam is installed with bail.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, realize mechanization garland pollination, improve the efficiency of garland, ensure farthest to realize supplementary pollination rate in a florescence interval, thereby improve pollination rate, improve former manual garland and had inhomogeneous phenomenon, and then improved the output of the production of hybrid seeds; Swing arm in technique scheme can be adjusted according to the actual height of Culm of Rice the high and low position of hawser, thereby reaches the object of a tractor serves several purposes; Utilize said structure to realize auxiliary garland pollination, greatly improved operating efficiency, alleviated labour intensity, but also can once expand the width in pollination rice field.In addition the utility model also have simple in structure, be easy to manufacture, the advantages such as convenient storage.
