Description
Technical field
The utility model relates to cigarette seedling technical field, specifically, is a kind of cigarette seedling canopy drip-proof structure of the injury seedbed that prevents from dripping.
Background technology
Between nursery stage, seedling raising greenhouse humidity is high, when the rising of seedling temperature of shed causes internal-external temperature difference larger, can steam be produced in seedling canopy and rise to canopy film top and form the globule, because canopy film top is arc, the globule can to two side rolls, when adhesion between the globule and canopy film cannot bear the gravity of the globule, the globule will drip, the globule fallen has stronger impulsive force, splashing on cigarette seedling easily causes cigarette seedling to damage, time serious, matrix in seedling dish is gone out, if in seedling dish during excess moisture, be easy to once cigarette seedling seedling (dead seedling) morning, the survival rate of serious reduction cigarette seedling, wherein seedling dish humidity excessive and cause anthracnose, the damping off incidence of disease is higher.In actual conditions, most of globule mainly in seedling raising greenhouse both sides drip, therefore, impaired cigarette seedling is mainly distributed in both sides in canopy, and the cigarette seedling of centre be subject to hardly the globule fall impact.
In recent years, although seedling raising greenhouse promotes the use of Anti-fogging Film, dripping phenomenon still occurs, and is not solved, and dripping phenomenon remains a difficult problem for whole nursery link, and through investigation, because of dripping phenomenon, the cigarette seedling damage ratio caused reaches more than 15%.Countermeasure of the prior art is generally at the place's lower horizontal film laying that drips, the shortcoming that this mode exists is: globule whereabouts vertical impact film easily causes film deteriorates, and the moisture stored up in film is not easily derived, can ponding be formed, thus cause secondary to drip.
Summary of the invention
In view of the film rapid wear existed in prior art, ponding is not easily derived and is easily caused secondary to drip water problem, the utility model provides a kind of cigarette seedling canopy drip-proof structure of improvement, this structure is by arranging the oblique film that drips of inclination in both sides, not only can reduce the impulsive force of the globule, also can not cause seeping phenomenon, be conducive to the derivation of moisture, thus avoid the globule to damage cigarette seedling, improve emergence rate.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
A kind of cigarette seedling canopy drip-proof structure, comprise by frame and be supported on the greenhouse body that the canopy film on frame forms, in described greenhouse body, both sides are respectively equipped with some parallel distributed and the outward-dipping support in bottom, and parallel support described in both sides is fixed with the drip oblique film parallel with support.
Adopt the cigarette seedling canopy drip-proof structure of technique scheme, owing to being provided with the oblique film that drips above the cigarette seedling of both sides, the globule that such canopy film top produces directly can drop to and drip on oblique film, underground is flow to again from oblique film both sides of dripping, avoid film to tile easy ponding to such an extent as to cannot moisture be derived, solve Yan Miaopeng and to drip the problem of damage cigarette seedling.
Further restriction, described pedestal upper end and lower end are fixed on frame respectively by fixture oblique pull.Conveniently the drip installation of oblique film of above-mentioned restriction is fixed, and the oblique film that drips can extend to above cigarette seedling further.
Further restriction, described in the drip horizontal width of oblique film be 1/4 ~ 1/3 of canopy film horizontal width.Because water droplet drop-off positions is mainly distributed in both sides in greenhouse body, the scope primary responsibility both sides that the oblique film that therefore drips covers, above-mentioned being limited to generally can process cigarette seedling canopy and to drip problem.
Further restriction, described in the drip angle of inclination of oblique film be 50 ° ~ 70 °.If dripped, oblique film angle of inclination is too little, so the drip distance of oblique film of ceiling distance is far away, such globule fall time is longer, when being dripped in oblique film surface in its arrival, speed is faster, add the oblique film that drips more vertical with globule action direction angle, the globule fallen more easily damages the oblique film that drips, certainly dripping oblique film angle of inclination should be not excessive yet, the cigarette seedling of equivalents will be covered so in the horizontal direction, its cost can corresponding increase, therefore dripping oblique film angle of inclination should be reasonable, both the not fragile oblique film that drips in globule whereabouts had been ensured, cost also obtains conservative control.

Embodiment
In order to make those skilled in the art can understand the utility model better, below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated.
As depicted in figs. 1 and 2, a kind of cigarette seedling canopy drip-proof structure, comprise by frame 11 and be supported on the greenhouse body 1 that the canopy film 12 on frame 11 forms, in described greenhouse body 1, both sides are respectively equipped with some parallel distributed and the outward-dipping support 3 in bottom, and parallel support 3 described in both sides is fixed with the drip oblique film 4 parallel with support 3.
The installation of oblique film 4 of conveniently dripping is fixed, and the oblique film 4 that simultaneously ensures to drip can extend to further above cigarette seedling 2 and prevent the globule, and support 3 top and bottom are fixed on frame 11 respectively by the fixture such as rope, hook 31 oblique pull.
But the oblique film 4 that drips need not cover the whole top of cigarette seedling 2 completely, because globule drop-off positions is mainly distributed on the cigarette seedling 2 of both sides in greenhouse body 1, for cost-saving, the horizontal width (projection width) of each oblique film 4 that drips of both sides only needs to reach 1/4 ~ 1/3 of canopy film 12 horizontal width, in a practical situation, have the oblique film 4 that drips of canopy film 12 horizontal width 1/4 substantially can process cigarette seedling canopy to drip problem.
More preferred scheme rationally arranges the angle of inclination of the oblique film 4 that drips, test through test of many times, the drip angle of inclination of oblique film 4 is arranged within the scope of 50 ° ~ 70 ° relatively good, because drip, oblique film 4 angle of inclination is too little, the globule fallen more easily damages the oblique film 4 that drips, oblique film 4 angle of inclination of dripping is too small, and the coverage of cigarette seedling 2 is too little.
The utility model is by arranging the oblique film 4 that drips of tilt distribution in both sides, the globule being conducive to that canopy film 12 top produces directly drops onto and drips on oblique film 4, and then flows to underground from oblique film 4 both sides of dripping, and solves Yan Miaopeng and to drip the problem of damage cigarette seedling 2.
Above a kind of cigarette seedling canopy drip-proof structure that the utility model provides is described in detail.The explanation of specific embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
