Description
Technical field
The present invention relates to the anti-bird technical field of agricultural, and in particular to a kind of sporadic color bird prevention net.
Background technology
The target of crop breeding is fitted with increasing yield, enhancing resistance, enhancing crop to conditions such as problem soils, water conservancies
Answering property is attached most importance to, and is to improve crop quality, improve the shortcut of production efficiency.The important breakthrough of China in this regard is the seventies
The incubation of hybrid rice, it is that the yield of brown rice for increasing substantially China and the world has made major contribution.For many years, country not
The disconnected input increased to crop breeding, also than more significant, improved seeds emerge in an endless stream the effect received, realize agricultural volume increase,
Increasing peasant income.But because breeding base lacks the preventive birds harm installations such as necessary enclosure wall, solarium, the crops of numerous breeding experts are former
The valuable breeding material such as kind, core authors is often lost because of bird pest, causes the loss of scientific achievement and prolonging for breeding time
It is long.
China is vast in territory, and species enrich, across a variety of climate zones.Advantageous natural conditions cause China to turn into generation
One of Bird Resource country the abundantest in boundary, more than the 9000 kinds of bird to survive in the world at present, China just occupies more than 1200
Kind, account for more than the 14% of world birds.With the enhancing of common people's environmental consciousness and the recovery of ecology, the type and quantity of birds are all
In upward status, sparrow etc. is also gradually revealed using paddy, beans, fruits and vegetables as harm of the birds of food to crops, to making
The harm of thing breeding is even more to become clear day by day.They peck at the paddy being just in the milk in breeding field and immature vegetables and fruits, bring simultaneously
Disease infection other materials, causes breeding material to be lost, and data misalignment, scientific research process seriously lags.Solves scientific prevention and cure in time
Bird pest, mitigate the harm to crop breeding, into a difficult problem of the current pendulum in face of agri-scientific research worker.
In general, the field of breeding is all smaller, little to area requirements, and this is just provided to the selection in breeding place
Very big leeway, to avoid the harm of birds, under the conditions of breeding water and isolation etc. is met, the selection that should try one's best is away from blocks
Crops, meadow, the woods, pond, house, these places provide the food needed for birdife, are birds activities and inhabit
Place, birds frequent activity；Field of the live wire frame through overhead should not also make breeding field, because birds have on electric wire
The custom of cluster.Breeding place can reduce the probability that breeding crop is found by birds away from above-mentioned environment, reduce the harm of birds.
For protecting harmful bird, typically there are following several method, sound bird repellent.The sense of hearing of birds is similar with the mankind, Ren Leineng
The sound enough heard, birds can also hear.Sound bird repellent refers to frighten birds away using sound, and this is also more traditional
Bird repellent method.What using effect was obvious at present is electro-acoustic bird repellent, and electro-acoustic bird-scaring unit is produced using digital technology
The wail of variety classes bird, birds are allowed to feel sick and sense of insecurity, in addition, this sound can also attract their natural enemy
Come over, while the birds to pass by one's way are frightened away.Traditional sound bird repellent method mainly has coal gas big gun, whistle（Gong, drum）, set off firecrackers,
These methods in a short time can only frighten birds away, and the time adapts to once long birds, be generally used for the short of harvest season
Several days time.Vision bird repellent.The vision of birds is fine, can observantly find that mobile object and their natural enemy are present.It is classical
Vision bird repellent method it is a lot, two kinds are common are in production, first, taking be wounded in action bar or flash strip, also has and balloon is drawn colors
Terrified hawkeye is hung on the edge of a field.Different colors is hung according to the difference of birds, such as white, black, yellow, on mountain
The serious place of bird bird pest hangs yellow, and this is the color that mountain bird is least ready to see, sparrow is smaller to the fear of balloon and colour bar,
Some birds are to these things even without reaction.These general things must necessarily be placed in above crops and orchard, can waft
Float and seem comparison more truly.Second, making natural enemy model, the false eagle made, cat owl and snake model are suspended on field
Between the edge of a field.But this bird repellent mode can only maintain one shorter time, the length of time one is easy for being penetrated, and birds are no longer
Fear these natural enemies, or even start to start to nest on these models.Draw in the net bird repellent.In general, bird is drawn in the net to block just in crop field
Mean most money of blossoming, most commonly used labour.But it is simple and easy thing to breeding field, plus knitmesh in recent years
The price of material constantly declines, and the technology for drawing in the net to hinder bird is also updated, for the high breeding crop of scientific research value,
Bird repellent is also a good selection in this way, because drawing in the net that breeding field can be protected to greatest extent, it is ensured that yield.
Existing market has various materials and the net of specification, selects which kind of net to depend primarily on the layout of breeding material and breeding facility.Set
The anti-bird of sack.In the case that breeding material amount is few, fairly simple practicality, last sack is covered to the fruit in breeding field, work is light
Pine, it is simple to operate；Fruit bag can be with self manufacture, and material is it is noted that selection can allow fruit to carry out good photosynthetic material.Fruit
Though bag wants running audit to preventing birds breeding material from playing certain preventive effect, it is impossible to adopt a casual attitude, some ground
Area, for the small birds of the big face as magpie, it is lead-pipe cinch to peck out a hole.The anti-bird of chemistry.The change of bird pest
Learn preventing and treating to refer to spray the biochemical substances that birds are reluctant to peck at or felt under the weather on fruit, force birds to be looked for other places
Food.Several years ago, chemicals is debated endlessly for bird repellent, is not only due to ineffective, and have secondary work to the health of people
With China's application is seldom.
In above-mentioned various methods, sound bird repellent and the anti-bird of set sack find that its effect is bad by practice；And the anti-bird of chemistry
Certain harm can be carried out to environment and the health care belt of the mankind, drawing in the net anti-bird can cause to hinder to a certain extent in itself to birds
Evil, results even in the death of birds.The anti-bird of vision is a kind of means of defence more feasible at present, but it has protection again
The defects of time is short.
The present inventor by the anti-bird of vision and draws in the net anti-bird and combines and can yet be regarded as by observing and testing discovery for a long time
A kind of good preventive means, first, the anti-bird of vision will not damage in itself to birds, although it has temporal limitation
Property, but can be made up by drawing in the net protection.So-called accidental color, refer to when creating generation because the intervention of accidentalia causes
The free hair tonic of color, is presented vivid dissipations, skewness, the wrong open color phenomenon folded of level, accidental color bird prevention net by
In its scrambling and irregularities, it is possible to prevente effectively from the adaptability that is formed after birds observation for a long time and immune
Property, the technique effect of vision bird repellent can be effectively obtained.
But common bird prevention net can not play good vision protection effect, and simply set on tradition is drawn in the net
Put that vision mode is also improper, therefore, it is necessary to developing a kind of new protective materials prepares protection network, protection network is had in itself
Changeable visual effect at random, while also there is the characteristics of drawing in the net protection, play vision protection and protect what is mutually cooperateed with to prevent with drawing in the net
Protect effect.
