Description
Technical field
The invention belongs to agricultural machinery field, and in particular to a kind of gas decompression return-flow structure and with the reduced-pressure backflow knot
The pollen trap of structure.
Background technology
China was fruit big producer of the world, since 1993, China's fruits output and cultivated area exceed India,
Brazil and the U.S., occupy the 1st, the world.2015 about 20,000,000 hectares of end of the year China's fruit cultivation areas, account for world's fruit cultivation
The 1/5 of the gross area；National about 260,000,000 tons of fruit annual production, accounts for 20% or so of world's fruit total output.
China's application has had been switched on " peasant+cooperative society+villagers' committee " joint implant pattern in recent years, forms big
Scale industrialization is produced.Although the road for having moved towards industry production of the application of China gradually, current institute face
The predicament faced is still obviously.It is that yield is unstable first, biennial bearing phenomenon is clearly；Next to that fruit size is very
It is uneven；3rd is that fruit shapes are bad, many malformed fruits.Tracing it to its cause has variety problem, planting technology problem and florescence pollination
Problem etc..The influence of wherein florescence pollination is protruded very much, and because China region is broad, the various in style and landform grown fruit is answered
It is miscellaneous so that fruit tree the florescence by Pollination Effect greatly receive ecological environment and restricted, especially in some special times, than
Such as florescence runs into overcast and rainy, cold current, frost, strong wind, sandstorm bad weather, and insect activity reduces or at all can not be movable,
Again because pollen relatively glues weight, the distance that wind-force is propagated is limited or even can not propagate, and causes fruit tree can not complete pollination, orchard is just
Meeting Severe Reduction, and the growing way of fruit is also bad.At this moment artificial pollination is carried out, acts on especially prominent, just can be to greatest extent
Keep high and stable yield good quality and high output and the big shape of fruit is just.Facts have proved the percentage of fertile fruit of artificial pollination can bring up to more than 95%,
More than 30% can be increased production, this meaning to application industry is very great.
The application artificial pollination of current China also rests essentially within the artificial stage directly pollinated, mechanization and informationization
Equipment application seldom, is badly in need of wanting the artificial pollination equipment of a practical material benefit to break through this bottleneck.And pollen collection is to carry out
The first step of artificial pollination, the quality of pollen quality directly determines the actual effect of artificial pollination.Existing pollen trap is equal
It is used to study to collect pollen sample, its pollen collection speed is slow, efficiency is low, it is impossible to meet the need of large-scale industrialized production
Will.
The content of the invention
