Description
Technical field
The present invention relates to a kind of planting machinery, relate in particular to a kind of backpack breeding of hybrid rice pollination machine and method thereof.
Background technology
Hybrid rice pollination technique requires by force, required precision is high, time requirement is tight, must within the limited time, complete pollination operation, and pollinating fully, is uniformly the key that guarantees seed-setting rate, raising seed production quality and output.At present, artificial supplementary pollination comprises manpower type and mechanical type, adopts powder-storage-spraying type pollination.Manpower type pollination is as traditional Pollination Modes, as single long pole is caught up with powder method, two short pole pushes away powder method and rope draws powder method, it is higher that it is that single long pole catches up with powder method, two short pole to push away the seed quality that powder method Pollination Modes gathers in the crops, specific yield is higher, but it is inhomogeneous to pollinate, labour intensity is large, production efficiency is low, can not meet the demand for development of modern seeding technique.The development that mechanical type pollination production efficiency is high, easy and simple to handle, be adapted to modern production of hybrid seeds large-scale production, mainly comprise two kinds of collision type and pneumatic types, collision type easily causes damage to plant, pneumatic type is as adopted small-sized helicopter pollination, and productivity ratio is high, but air velocity has downward component velocity, make partial pollen can not diffuse to the female parent of both sides, when simultaneously wind speed is low, pollen can not come off, when wind speed is high pollen drift too far away, Pollination Effect is not ideal enough; Adopt powder-storage-spraying type pollination, whole process complex procedures, deal with easy damage pollen cell improperly, long-time storage reduces pollen activity, hybrid seed yield is not high.Therefore, need to develop especially a kind ofly adapt to that pollen is propagated in good time, suitable to plant impulsive force, pollen fed distance is moderate, uniform pollination, breeding of hybrid rice pollination machine that productivity ratio is high.
Summary of the invention
To the object of the invention is to adopt powder-storage-spraying type pollinating process complexity and the shortcoming such as specification requirement is high, artificial pollination efficiency is low, plant is easily hindered in machinery pollination, strength Pollination Effect is poor in order overcoming, a kind of backpack breeding of hybrid rice pollination machine and method thereof to be provided.
