Description
Technical field
The invention belongs to agricultural technology field, specifically, it is related to a kind of controlled-release device for being sustained volatile materials, its energy
Volatile materials is enough allowed to be discharged with even speed completely, it is possible to substantially completely to discharge volatile materials therein.This hair
The manufacture method of the bright controlled-release device for further relating to the sustained release volatile materials.
Background technology
It is well known that the volatile chemical of low-molecular-weight is agriculturally not only to have had many purposes there is also potential
Purposes, including using volatile chemical as the attractant and repellant for insect.In insect attractant
Sex pheromone is a kind of volatile chemical signal by being used to attract each other and send between the similar opposite sex, and insect polymerization letter
Breath element is then typically produced by the insect of a certain sex, plays a part of aggregation, and aggregation pheromone can simultaneously attract similar
Male and female insects.Additionally, also have other volatile materials such as methyl eugenol, raspberry ketone, zingiberone in insect attractant,
And these volatile materials are produced by plant originally, but can be to attract with it to be the male fruit fly eaten, and by this letter
Breath element is passed and is changed to the attractive material of female fruit fly.
Additionally, there is the volatile materials with avoidance effect, these volatile materials are included such as gaultherolin, it
While walking quickly and keeping away the insect brown paddy plant hopper on paddy rice, it is also equipped with luring its natural enemy i.e. effect of egg parasitoidses Anagrus nilaparvatae.
In addition, historically, be taken from plant or some volatile chemicals similar to plant, when being discharged into air
When middle, there is good avoidance effect to mosquito.These volatile materials include but is not limited to citronellal, linalool, geraniol.
Thus, some important insect pests are controlled using the volatile materials of safety have become it is a kind of highly effective
Means, it is more and more important for environment and the producer.
Additionally, chemical signal can be discharged by the volatile compound with bioactivity between plant exchanged,
Such as plant can secrete the activity of methyl jasmonate early warning other crops on insect on plant, and these chemical signals are around
A kind of chemical defence is established between plant, some chemical substances for being unfavorable for insect digestion are secreted.Furthermore, these plants
Chemical signal is also possible to influence the growth result of some crops between thing, for example, the chemical substance of certain plants secretion can strengthen
The bright-coloured degree of apple color.
However, due to volatile chemical easily rapid volatilization in atmosphere, so a kind of controlled release must be placed it in
Volatilized in device, it is permanently effective to ensure their slow releases in a long time.
It is well known in the prior art to have solid kind controlled-release device, i.e. volatile chemical is blended in by wax or high score
In the solid kind controlled-release device that sub- polymeric material is made, the lure that such as wax stone or glue head do, this kind of product makes very simple
It is single, but rate of release it cannot be guaranteed that, the speed and concentration of the volatile chemical volatilization in its rate of release and controlled-release device
There are much relations, when the volatile species concentration reduction in wax stone or glue head lure, rate of volatilization can also be reduced therewith, be entered
And impact effect.Although this controlled-release device is simple, the significant wastage of volatile chemical is caused.Because waving at the beginning
Volatile material release ground is too fast too many, and remaining volatilizable chemical substance just becomes very little because of concentration step-down quickly.This feelings
Shape causes the effect on driving birds is not good for reaching.Especially reached by Insect pest suppression technology when using a large amount of expensive insect sex pheromones
When preventing and treating purpose, this kind of volatile compound is expensive, and the waste of early stage causes cost very high.
Additionally, the glue head lure containing sex pheromone is used as the controlled-release device for the purpose of luring, lure release concentration mistake
During sex pheromone high, targeted insect may be played a part of to walk quickly and keep away rather than be attracted；And concentration it is too low when, then can not be to mesh
Mark insect has enough attracting abilities.Thus, both of which is not suitable for trapping and killing as purpose practical application.Such control
Release device can not be precisely controlled to the volatile concentrations of volatile materials and speed.
It is well known in the prior art to also have storage class controlled-release device in addition to foregoing solid kind controlled-release device.Generally and
Speech, can contained volatile materials be discharged into close to zero control device be referred to as store class controlled-release device.Existing difference
Some have been commercialized in the storage class controlled-release device of type.
A kind of extrusion tubulose controlled-release device is disclosed in United States Patent (USP) US No.4,600,146.Wherein, one is disclosed to squeeze
Go out the capillary release of formula, extruder injects pheromones while capillary is extruded, and is then cut off sealing.The pipe of capillary
Chamber is narrow (diameter is usually 1 to 3 millimeter), if it is desired to filling capillary sky with pheromones again after normal temperature state, extrusion capillary
The frictional resistance produced during pipe can be very high, so that thinking that the way for being filled up completely with full these capillaries again after the extrusion cannot be in life
Realized in product.In actual industrial metaplasia product, the injection of the extrusion and pheromones of capillary is carried out simultaneously, is then carried out again
Cutting and sealing, at a high temperature of filling information element means that pheromones have been exposed to molten plastic while capillary is extruded,
And to be realized while extrusion accurate filling production process is costly and troublesome poeration.Additionally, there is many hosts
Plant volatile or similar compound cannot be used for filling such capillary, because many of which Herbivore
The boiling point of compound is near or below the fusing point of plastics.Meanwhile, this capillary release cavity volume is limited.Host plant is waved
The use of hair property compound is generally more than the consumption of insect pheromone, thus this kind of compound is not suitable for hot filled capillary pipe.
United States Patent (USP) US No.4, disclose a kind of packed controlled-release device in 923,119, it use one and simply may be used
The packed release of release pheromone.The advantage of this release is low manufacture cost.Actually they are to be adapted to be filled up completely with
Type.The shortcoming of this release is very thin wall, in general wall thickness about 0.01mm.Although this packed release is indoors
Show good in the laboratory environment of temperature control, but this kind of packed release containing pheromones easily goes out in temperature environment high
Existing pheromones largely promptly discharge, and thereby result in waste, influence its efficiency.
United States Patent (USP) US No.5, disclose a kind of capsule controlled-release device in 316,148, it specifically discloses a kind of vacuum
Capsule release.One side of the release is impermeable, and another side is that a kind of very thin film is constituted, releasably
Pheromones.This film used on orchestration of releasing inevitably runs into that bag-shaped controlled-release device described above is same to ask
Topic.
Additionally, disclosing a kind of controlled-release device in German patent DE 3640880, it is equally blow-molded, and heat is filled out
Fill and be tightly connected.The composition of the controlled-release device has one or two thin-walled capsule for top, and bottom also has one to contain information
The reserved cavity of element, upper thickness is 0.02-0.15 millimeters, by its upper film release pheromone.But because of bottom wall thickness,
Make this part of bottom according to the predetermined normal release pheromone of speed pheromones can not be caused largely to remain in the reserved chamber in bottom
Body causes to waste.In addition the manufacturing cost of this release is higher.
In addition, foregoing lure is also targeted insect to be monitored and is observed and predicted with pheromones, this technology
Existing history for many years.The purpose of monitoring is mainly and gathers certain insect in the generation in field, algebraically and population active situation.It is logical
Monitoring Data is crossed, farmer can in time understand target insect pest, and a situation arises, takes prophylactico-therapeutic measures in time when needed.Typically
In the case of, the quantity that monitoring lure is used is very little, for example：Using 1/10-20 mus, in this case, lure is only in prison
Play a part of to lure in survey, the population quantity of target insect pest can't be influenceed and a situation arises.
However, in practical application, many insects can be reached anti-using a large amount of methods trapped and killed using aggregation pheromone
The effect controlled.But the pheromone dispenser used during trapping possesses the function of slow release long-acting, and this point is for commercialization field reality
Using being all very important, otherwise frequently change lure and the substantial amounts of labour cost that causes can allow this trapping method because
Expense peasant too high cannot bear and can only rest on the stage observed and predicted.
Some important moth worms can also be prevented and treated with the method for trapping.Such as corn borer (Ostrinia
Furnacalis) and rice-stem borer (Chilo suppressalis), compared with above-mentioned large-scale insect, these moth worms
Only needing to little pheromones can just play a part of to lure, and each lure only needs to the pheromones less than 0.2mg, and these
Pheromones are often sex pheromone.These sex pheromones have volatilization, and volatilization can attract similar male, allow this in atmosphere
A little sex pheromones can continue long-acting release then to be needed to be placed on sex pheromone in the release for possess slow releasing function and could rise
To effect.
In general, to be all the lure made by small rubber head carried the pheromones of small-sized moth worm, though this method
So it has been used many years but still has had significant limitation.First, the lure being made of small rubber head carrying information element
Evaporation rate is unstable, equally at 25 DEG C, after half pheromones are released, and the burst size meeting of pheromones in daily lure
Original half is reduced to, this means that the burst size of beginning is too high, and burst size below is not enough, causes to waste.Its
Secondary, in addition to burst size is unstable, effective efficiency time of Rubber end lure is very short, is usually no more than one month, so
At least need every month to change once, then for insects such as preventing and treating striped rice borer, a Growing Season of Crops is accomplished by changing at least
6-7 times, not only increase cost, labour cost also can be very expensive, be completely unsuitable for commercially use and promote.Rubber end lure
The pheromones amount that limitation is also embodied in a Rubber end and can carry is very limited amount of, is volatilized when a large amount of other of mixing are needed
When property compound is come the attraction for strengthening main compound, the pheromones amount that Rubber end can be carried but because cannot be effectively increased and
It is restricted.
Therefore, in the prior art in the urgent need to one kind can solve the problem that foregoing problems, both realized making volatile materials with complete
Uniform speed discharge and can reach the controlled-release device for finally making it cannot not volatilize surplusly residual completely, and the controlled-release device again may be used
