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
The hybrid rice pollination technique requires by force, required precision is high, time requirement is tight, must finish the pollination operation in the limited time, and pollinating fully, uniformly is the key that guarantees seed-setting rate, raising seed production quality and output.At present, artificial supplementary pollination comprises manpower formula and mechanical type, adopts powder-storage-the spraying type pollination.The pollination of manpower formula is as traditional pollination mode, as singly long pole is caught up with the powder method, two short pole pushes away the powder method and rope draws the 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 mode gathers in the crops, specific yield is higher, but it is inhomogeneous to pollinate, labour intensity is big, production efficiency is low, can not satisfy the demand for development of modern seeding technique.Mechanical type pollination production efficiency height, easy and simple to handle, the development that is 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 pollinated as adopting small-sized helicopter, the productivity ratio height, but air velocity has downward component velocity, make partial pollen can not diffuse to the female parent of both sides, pollen can not come off when simultaneously wind speed was low, when wind speed is high the pollen drift too far away, the 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 especially development a kind of adapt to pollen propagate in good time, to the plant impulsive force is suitable, the pollen fed distance is moderate, uniform pollination, breeding of hybrid rice pollination machine that productivity ratio is high.
Summary of the invention
To the objective of the invention is to adopt powder-storage-spraying type pollinating process complexity and shortcomings such as specification requirement is high, artificial pollination efficient is low, plant is easily hindered in the machinery pollination, strength pollination weak effect in order overcoming, a kind of backpack breeding of hybrid rice pollination machine and method thereof to be provided.
