The air flow auxiliary biopesticide used towards facilities horticulture sprays centrifugal atomization apparatus
Technical field
The present invention relates to the biopesticide used for facilities horticulture to spray or atomising device, the air flow auxiliary biopesticide being specifically related to use towards facilities horticulture sprays centrifugal atomization apparatus.
Background technology
Continuous all the year round plantation in facilities horticulture and hot and humid condition are that the breeding of pathogen creates adapt circumstance condition, some germ worm's ovum and insect are bred year after year, because facility cultivation carries out in the space of relative closure, the use of chemical pesticide will increase the poisoning and pollution to environment of Residual Pesticides in Farm Produce, operating personnel greatly.
Biopesticide refers to and directly utilizes biological living (as fungi, bacterium, nematode, insect viruses, genetically modified organism, natural enemy etc.) or utilize biogenic physiological activator (farm antibiotics, plant growth regulator, sex pheromone, food rcstriction agent, juvenile hormone etc.) to carry out the preparation killed or suppress for agriculture and forestry pest, have safe and efficient, decompose rapidly, selectivity is strong, low-residual, efficiently, not easily the advantage such as to develop immunity to drugs.For biological living agricultural chemicals, how to keep its active injury-free be the key of flusher.
The prevention and elimination of disease and pests effect of biopesticide and environment have close relationship, one is temperature, and the active component of biopesticide is primarily of protein crystal and lived gemma composition, higher to temperature requirement, when biopesticide uses, temperature must be controlled at 15 ~ 30 DEG C.Two is humidity, and biopesticide is very responsive to the requirement of humidity, and ambient humidity is larger, and drug effect is more obvious.Three is ultraviolets, and ultraviolet has fatal lethal effect to biopesticide, and best open air should be selected the cloudy day or spray biopesticide at dusk.
Use the requirement for environment for biopesticide, green house has outstanding superiority, and one is temperature, and due to airtight space, temperature is higher, generally can higher than outer more than 10 DEG C of canopy; Two is humidity, by the water vapour that ground moisture evaporates and transpiration effect produces, is mostly trapped in canopy, and air humidity, apparently higher than outside canopy, often occurs the humidity of more than 90%, and the duration; Three is ultraviolets, and because plastic tunnel is by plastic foil or glass lighting, therefore, intensity of illumination is low, light of poor quality.As fully visible, use biological pest control to ensure drug effect in green house, alleviate pollution again, not residual.
Centrifugal spraying adopts very low pressure, and liquid is radially flowed on the disk of a High Rotation Speed, is finally thrown out of formation droplet from the edge of disk, the mechanical damage of this atomizing type to biopesticide activity is little.The feature of centrifugal spraying is that the droplet size formed is comparatively even, particle size easily adjusts, and coverage is large, and shortcoming is that penetrability is relatively poor.
For the feature such as short, intensive of crop in facilities horticulture, the agricultural chemicals sprayed away want wide coverage, penetration of droplets performance good, can be deposited on the target sites such as crop leaf in a large number, and low toxicity, low-residual, pollution are little, therefore develop for facilities horticulture, the active atomising device pole that can keep biopesticide is necessary.
The patent that denomination of invention is " wind spraying aid type centrifugal atomizer a kind of test device for air-assisted spraying (patent No.: 200920035407) " provides a kind of atomizer for spray liquid, the droplet thrown away by atomization tooth all directly can be in blower fan and produce within the scope of wind field, to improve penetration power and the deposition of droplet, but its centrifugal atomizing rotating disk is covered with the centrifugal atomizing case be fixed on electric machine casing, centrifugal atomizing case periphery arranges atomization tooth, biopesticide is thrown to after on atomization case, atomization tooth on centrifugal atomizing case can cause the mechanical damage to the active secondary of biopesticide.The activity of biopesticide is the basic assurance of its drug effect, and this technology can complete atomization under very low inlet hydraulic, thus decreases the damage for biopesticide.
Summary of the invention
1, the technical problem that will solve is invented
Residue of pesticide and the pollution thereof of crop is cultivated for green house, and the atomizer of existing spray liquid is to the damage of biopesticide, and use the requirement for environment according to biopesticide, green house temperature is high, high humidity, the feature that uitraviolet intensity is low, the invention provides the air flow auxiliary biopesticide used towards facilities horticulture and spray centrifugal atomization apparatus, make can realize wide coverage under the prerequisite not affecting biopesticide activity, the atomising device used towards facilities horticulture that penetration performance is good, and the use of biopesticide avoids the residual of green house cultivation crop, alleviate pollution.
