Description
Technical field
The present invention relates to aviation plant protection technical field, more particularly relate to the boat of a kind of electrostatic liquor containing cotton defoliant
Empty spraying method and device.
Background technology
China is the most the third-largest Chan Mian state, and 2012 Annual planting areas reach 4,700,000 hm2, yield be up to 6,840,000 t.Cotton
Flower is one of the most time-consuming crops, and in addition to sowing, and most production link is not carried out mechanization, insect pest preventing and controlling,
Training is pruned, harvesting etc., expend a large amount of artificial.Particularly Cotton Gossypii is gathered link, uses amount of labour used when manually gathering big, needs
Put into substantial amounts of labour force.In recent years, the tightest along with problems such as human resources are in short supply, labor cost sharp rises
Weight, the comparative effectiveness reduction with the obvious advantage of Cotton Industry, therefore, it is the inevitable choice of cotton industry development that the mechanization of Cotton Gossypii is gathered.
Defoliation ripening is the important prerequisite of machinery cotton picking, is the important step in this systematic engineering of business of machine cotton picking, is to promote
The important measures that remaining green when it is due to become yellow and ripe late-maturing cotton field is precocious, utilize cotton defoliant, can improve blow-of-cottons rate before Cotton Gossypii frost, improve the product of Cotton Gossypii
Level, increases the income of cotton grower.Disleave quality directly affects the harvesting quality of Cotton Gossypii, and disleave quality determines Cotton Gossypii percentage of impurity, aqueous
Rate, decides quality grade and the selling price thereof of Cotton Gossypii.
Chemical defoliation is a kind of technology promoting cotton leaf to come off, and chemical defoliant has the effect accelerated the ripening to cotton boll, and
And owing to being conducive to field ventilation and penetrating light after disleave, cotton boll cracking blow-of-cottons can be promoted.But, whether the use of chemical defoliant obtains
When decide the effect of disleave, to plucking, deposit, a series of programs such as crudy produce and have a strong impact on, and affect Cotton Gossypii
Yield.

Although China produces number of types of cotton defoliant, but there is presently no and a kind of be specifically designed to the spray that cotton defoliant sprays
Execute system and sprayer apparatus, and the conventional agricultural plant protection machinery of tradition for cotton defoliant to spray defoliation effect poor, greatly
Droplet spray pattern is easier to cause the waste of defoliant, reduces the utilization rate of cotton defoliant to a certain extent, meanwhile, by
It is difficult to the surface maintaining the long period to be attached to cotton leaf in big droplet, runs off and seriously also easily cause environmental pollution.Ground
Apparatus sprays cotton defoliant, and due to this apparatus both bulk that sprays, not only working performance is low, and apparatus sprays in field
Implement operation and easily damage cotton plant, cotton boll by pressure, cause cotton boll easily to come off, finally affect output of cotton and quality, according to statistics, adopt
Ground mechanical work, output of cotton loss rate is used to be up to 15%.It addition, cotton defoliant spray have the highest ageing,

Complete period large-area to spray job task in order to spray at optimal defoliant, some large-scale cotton planting in northwest
District takes the lead in employing manned fixed wing airplane and defoliant sprays operation in the air.Aviation is taked to spray cotton defoliant
There is lot of advantages.One, it is high that Aircraft Air sprays working performance, can reach about 10 times of traditional instruments working performance, its
Two, aircraft does not directly contact with crop in spraying operation process, avoiding problems ground and sprays apparatus and be expert at operation
Process rolls cotton plant and causes the problem of shedding even cotton plant necrosis, greatly reduces the loss rate of output of cotton.But someone
Drive an airplane and carry out cotton defoliant and spray operation and there is also some shortcomings being difficult to overcome: manned fixed wing airplane needs
Special airport and runway, need to take substantial amounts of arable land, and meanwhile, manned machine operation speed block, in cotton crop trophophase
Later stage branch and leaf are luxuriant, and this results in cotton defoliant and is difficult to penetrate the top of Cotton Canopy thus is deposited in cotton plant middle and lower part, leads
Cause disleave is incomplete.
It is low, light without special pilot, special landing airport, flexible operation that plant protection depopulated helicopter has operation height
Just, the outstanding advantages such as environmental suitability is strong, additionally, the rotor of unmanned plane produces downward rotor wind field advantageously in accelerating medicine
The sedimentation that liquid mist is dripped, contributes to cotton defoliant penetration of droplets blade sedimentation cotton plant middle and lower part.Therefore, plant protection unmanned plane carries out cotton
Spraying of flower defoliant, increasingly receives publicity in agricultural production.
But, current domestic cotton defoliant medicinal liquid is mainly based on water preparation, and plant protection unmanned plane is because of the limitation of its loading capacity
Property, sprays the purpose of working performance to reach to increase substantially, can only enter with high concentration, low discharge and little droplet Sprayable
Row sprays operation.But during little droplet operation, on the one hand droplet drift is more serious, during the most simple water preparation sprays, mist
Being easy to evaporation before dropping in arrival crop canopies, the effect of settling of droplet is poor.Otherwise, increase deposition effect according to big droplet
Really, then the water yield that water preparation preparation cotton defoliant needs is relatively big, and same sortie drug loading is limited, adds the landing of unmanned plane
Sortie, does not reaches and improves the requirement spraying efficiency.
