30MHz visited the Rheinberg ( Germany ) location , where they were given a tour of duty through the brand name unexampled elect nursery from Christiaan Rinkel and Liza Lievens . Elite is the quarantine phase angle ( the plants that are not yet declare negative for disease ) , and the library phase angle ( the plants that are white and ready for the supplying concatenation ) . At the postulation of the Breeding Department , more than 150 unlike cultivars are find and screen in the quarantine department to keep the flora as healthy as possible . The Elite greenhouse is an important milestone in the development and execution of Dümmen Orange ’s Greencare programme .
Greencare is the phytosanitary policy of Dümmen Orange , aim to supplying healthy and clean cutting fabric to agriculturalist worldwide and includes compulsory hygienics measures for both employee and output facilities . The employee shower on arrival and put on work wear . Anything brought into the edifice is disinfected first and often does not get any further into the construction except for the canteen . At each greenhouse , staff have to wash their hands again and after which they put on nitrile glove with diesel mitt on top ( diesel baseball glove are the fictile mitt you find at gun station ) . If a industrial plant does get grim , the protocol is ; extra isolation , after which the phytosanitary squad searches for a solution in collaboration with production specialists and breeder . However , this is very different for each plant .
The 30MHz team spoke to Liza Lievens , Grower of Elite and asked her a few questions .
Which variable do you record in the greenhouse and which systems do you utilise for this ?
brightness in uMol&PARWe measure the amount of light to see what the plants have had in total in one sidereal day , and for example with this we also control watering .
We also quantify the radiation in watts , with this we control the curtain .
Temperature inCelsiusTemperature can be influenced by humidity , pipe heating , curtain opened / closed ; free energy cover ( in winter it lets the igniter get through , but keeps the warmth in ) , black out curtains can sometimes facilitate for extra spook during hot days and then we have a blending curtain , this ensures that we have no unmediated sun in the glasshouse ( saltation , summertime and sometimes fall ) .
humidness in the greenhouse in percentages and absolute humidness ( density per m2)Humidity is manipulate by the computer , what we define is achieved through a fogginess organization .
Pressure in PascalThe pressure is measured in Pascal and principally has to do with the fact that we have a semi - closed greenhouse ( 5 air vents per 600 m2 nursery ) with an overpressure system and this way we keep the worm out ( in summation to thrips final in the windows ) .
weewee ( EC / pH ) in silos and trickle / drainEC / pH : because we mature everything on Lucius Clay granule , we only have a modest buffer and we can respond like a shot to EC / pH economic value . We have 2 silo with unlike EC values , high and low ( considering the issue of different plant we have in our greenhouse , from Sedums to Petunia ) . We can check watering and EC per 7 board . We need the pH to be between 5.5 and 6 for both silos . By always measuring this , we conform the amount of water system ( amount of water system and duration of lacrimation ) . control EC can help to grow . you may control plants with this , but with such a large amount of species ( 155 ) , it ’s not prosperous .
Pot moisturePot wet is assess by a sensor in the lot . We measure dripping and drain and we adjust the pH consequently . Because the industrial plant should not get too much urine , it ’s utile to measure pot moisture . Especially with succulents , sedum , and kalanchoe , it can be harmful to give a muckle of piss .
We grow everything on cadaver granule and that is why it is very important to monitor the pot moisture , not too dry , not too soaked .
Why do you valuate these variable ? What is the underlying idea?To set aside the plants to uprise and keep as vegetal as potential and prevent florescence inductance . ( Generative part of a plant are hormonally different and can , therefore , have a negative influence on the tests that we carry out ) .
What is done with these insights?The variables are set to the want of the plants and how we , as agriculturalist , require them to be ( vegetational and productive ) . To prevent plant from flowering , we place them in a spot where they do not bloom . This can be , for example , that Kalanchoe is on a longsighted solar day since it will flower on a short sidereal day . A yield raiser has varying hours to assure the industrial plant towards flowering so that it part bloom at the right time . We attempt to maneuver that it is not going to bloom .
Vegetative is when a plant is in growth and not yet flowering . Productive is when a plant continues to get , so when you see changeless renewal at a flora . By constantly keeping the plant on a short day , they can also simply “ think ” that it is autumn / wintertime , and do nothing anymore . They then wait until spring ( which remain out ) . We also need to keep these plants fat and vegetative ( so actively growing but without peak ) .
How do you see the future in data point collection?Collecting datum is very significant to us . We now start to get data point after a class that we can equate with the data from last twelvemonth to adjust or switch plans . It is also very interesting to see that we are making advancement , we have a much better view of what is happening in the glasshouse and especially with the plant . We can now explain much more and keep on to work on that .
The future of information collection is fully automatise , but the judgement of this information is human body of work , as is the assessment of the plants . When there is one harvest , this is well-situated to automatize . fortuitously , not everything is automated , because ensure and reviewing is the best thing about this job for me . By occasionally pull in data manually , you see more and you may make link faster than if you only get the results .
