Description
Buisleiding voor irrigatie en beregening van gewassen.Pipeline for irrigation and sprinkling of crops.
De onderhavige uitvinding heeft betrekking op de constructie van de buisleidingen,welke worden gebruikt voor het toevoeren van water aan gewassen, in het bijzonder, doch niet uitsluitend, in kassen. Diverse groenten en bloemen worden gekweekt in kassen, waarby de zaden, knollen of jonge plantjes in teelgrond of in een substraat van steenwol of granulaat worden gezet, terwijl licht, warmte en kooldioxyde-gehalte van de atmosfeer in de kas,aangepast aan de behoefte;wordt geregeld.The present invention relates to the construction of the pipelines used for supplying water to crops, especially, but not exclusively, in greenhouses. Various vegetables and flowers are grown in greenhouses, through which the seeds, tubers or young plants are placed in cultivation soil or in a substrate of rock wool or granulate, while light, heat and carbon dioxide content of the atmosphere in the greenhouse are adapted to the needs; is controlled.
Daartoe staan de jonge gewassen in de kas op de grond of op tafels.To this end, the young crops are placed on the ground or on tables in the greenhouse.
Het benodigde water wordt door buizen boven en/of tussen de rijen van de planten toegevoerd, waartoe deze buizen van regelmatig aangebrachte openingen of druppelaars zijn voorzien.The required water is supplied through tubes above and / or between the rows of the plants, for which purpose these tubes are provided with regularly arranged openings or drippers.
De aanvankelijk toegepaste metalen buizen zijn thans vervangen door kunststofbuizen.The metal pipes initially used have now been replaced by plastic pipes.
De hiertoe gebruikte kunststofbuizen blijken het nadeel te hebben, dat zij de belichting in de kas storen.The plastic tubes used for this purpose appear to have the disadvantage that they interfere with the exposure in the greenhouse.
Donkere buizen, zoals de doorgaans gebruikte grijze of zwarte buizen van polyvinylchloride of polyetheen, werpen schaduw op de gewassen, terwijl de watertemperatuur in de buizen door absorptie stijgt.Dark pipes, such as the commonly used gray or black polyvinyl chloride or polyethylene pipes, cast shadows on the crops, while the water temperature in the pipes increases due to absorption.
Hierdoor ontstaat algengroei in de buizen en mosgroei op de buizen en de druppelaars, waardoor verstopping ontstaat.This creates algae growth in the tubes and moss growth on the tubes and drippers, causing blockage.
De voor de controle van het relatieve vochtgehalte van de lucht in de kas en van het watergehalte in de teelgrond of het substraat uiterst kritische parameters van doorstroming, temperatuur en belichting worden daardoor ongunstig beinvloed.The parameters of flow, temperature and exposure, which are extremely critical for controlling the relative moisture content of the air in the greenhouse and the water content in the cultivation soil or substrate, are adversely affected.
Als voor de beregening of irrigatie aan het water opgeloste mest- of groeistoffen of antiparasitica worden toegevoegd, wordt de dosering daarvan gestoord, zodat by het in een kringloop rondpompen van dit water problemen van verzilting en kristallisatie kunnen ontstaan, die bijkomende kostbare en tijdrovende maatregelen vereisen, om het milieu niet te belasten.If fertilizer or growth solutions or antiparasitics are added to the water for sprinkling or irrigation, the dosing thereof is disturbed, so that circulating this water can cause problems of salinization and crystallization, which require additional expensive and time-consuming measures , so as not to pollute the environment.
Deze nadelen worden ondervangen door het toepassen van leidings-buizen volgens de onderhavige uitvinding, die is gekenmerkt doordat buizen van hard polyvinylchloride worden toegepast, die bestaan uit een witte buitenlaag en een zwarte binnenlaag.These drawbacks are overcome by using conduit pipes of the present invention which is characterized by using hard polyvinyl chloride pipes consisting of a white outer layer and a black inner layer.
In een alternatieve belichaming van de uitvinding bestaan deze buizen uit een witte buitenlaag, een zwarte tussenlaag en een witte binnenlaag.In an alternative embodiment of the invention, these tubes consist of a white outer layer, a black intermediate layer and a white inner layer.
De buizen hangen in de kassen in ryen boven de gewassen en kunnen ook op de grond tussen de bedden liggen.The tubes hang in ryen in the greenhouses above the crops and can also lie on the ground between the beds.
De vrij hangende buizen kunnen zijn voorzien van op regelmatige afstanden aangebrachte openingen of van conisch gevormde druppelaars of sproeiers van dezelfde gelaagde samenstelling.The free-hanging tubes can be provided with regularly spaced openings or conically shaped drippers or nozzles of the same layered composition.
Door de witte buitenlaag wordt het dag- of kunstlicht gereflecteerd, waardoor de watertemperatuur lager is dan in uitwendig zwarte of gekleurde buizen of in metalen buizen.The white outer layer reflects the daylight or artificial light, so that the water temperature is lower than in externally black or colored pipes or in metal pipes.
Door de uitwendig witte kleur van de buizen wordt aanzienlijk meer reflectie van het licht verkregen, waardoor snellere en betere groei en hogere opbrengst in de kassen wordt verkregen.Due to the externally white color of the tubes, considerably more reflection of the light is obtained, resulting in faster and better growth and higher yield in the greenhouses.
Door de zwarte tussenlaag of binnenlaag kan het licht niet doordringen, zodat geen algengroei optreedt, waardoor geen verstopping in de buizen, sproeiers en druppelaars kan optreden.Due to the black intermediate layer or inner layer, the light cannot penetrate, so that no algae growth occurs, so that no clogging can occur in the tubes, nozzles and drippers.
De gelaagde buizen volgens de onderhavige uitvinding worden in handelslengten door co-extrusie uit polyvinylchloride vervaardigd, waartoe kostenbesparend geregenereerd granulaat uit recycle-materiaal kan worden gebruikt.The stratified tubes of the present invention are manufactured in commercial lengths by co-extrusion from polyvinyl chloride, for which cost-effective regenerated granulate from recycled material can be used.
De uitvinding wordt toegelicht aan de hand van de bijgevoegde figuren. Figuur 1 toont schematisch,hoe de buizen in de kas worden aangebracht. Figuur 2 toont een doorsnede door een buis, bestaande uit 3 lagen.The invention is elucidated with reference to the annexed figures. Figure 1 shows schematically how the pipes are placed in the greenhouse. Figure 2 shows a section through a tube consisting of 3 layers.
Daarin is 1 de witte buitenlaag, 2 de zwarte tussenlaag en 3 de witte binnenlaag.1 is the white outer layer, 2 the black intermediate layer and 3 the white inner layer.
Figuur 3 toont een doorsnede door de buis, bestaande uit 2 lagen, waarin de lagen eveneens met de nummers 1 en 2 zjjn aangeduid.Figure 3 shows a cross-section through the tube, consisting of 2 layers, in which the layers are also indicated by the numbers 1 and 2.
Hoewel in hoofdzaak voor kassen bedoeld, kunnen deze buizen uiteraard ook voor beregening of bevloeiing van vrije velden toepassing vinden.Although primarily intended for greenhouses, these pipes can of course also be used for sprinkling or irrigation of free fields.
Uitgevoerde proefnemingen hebben de voorafgaand beschreven voordelen van de onderhavige werkwijze overtuigend bewezen.Experiments conducted have convincingly proven the previously described advantages of the present method.
