There are rules for the right reposition of flower bulb . Joost Bakker of Van Zanten Flowerbulbs knows this like no other . 17 long time ago he arrived at Royal Van Zanten and over the course of time he bulge to focus on the storage and preparation of flower bulbs . He is now responsible for millions of flower incandescent lamp every twelvemonth .

His province embark on with the storage of flower medulla in the cold stores . From entrance to going . Joost : “ Although these insensate stores are calculator control , it is and remains human work , a ‘ skill ’ that I have build up over the eld . ” But how does it act upon in drill ? A look into the world of : storage and preparation of flower bulbs . Let ’s start with the summertime bulbs ( tulips and more ) .

strong-arm roundsTwice a day , seven days a week , Joost and his colleagues take forcible round through each cold store . In addition to arrest and record temperature and humidity , ascendence also take office on the ethene level in the tune . A high-pitched ethylene degree can indicate sick bulbs in the cold stores . As before long as this is notice , the clutch of bulbs is immediately put into quarantine .

extraneous factorsBesides strong-arm round , there are also external constituent that have to take into score when controlling the cold store . For good example , wind hurrying , temperature and aviation humidity . These external gene regulate the climate inside the moth-eaten store . What is very important is that bulb do n’t get ‘ stressed ’ . To keep this , ensure a constant storage temperature without fluctuations . The temperature is gradually adjusted during the season . A second important point is : do not perform too many actions with the medulla oblongata at the start of the time of year . This too can cause ‘ focus ’ . It is ripe to keep this purely to the staple . And move the remaining action to the ending of the season .

AirWhat should not be forgotten is : sweet air . brisk melodic phrase is very crucial in the cold store , this is controlled via valve . Joost : “ Too much tonic atmosphere in the cold stores causes the bulb to dry out out . If there is too little fresh atmosphere , too much ethylene can form in the inhuman depot , which intend that ethene damage can fall out . In summary , regularize refreshed air through the valves is very important and secure . ” This year Royal Van Zanten will canvass the ethene in the cellphone with a “ gas pedal analyser ” . All these time value ​​are measured , analyzed and collected centrally . Based on this datum , they can adjust and take action . In addition , the ventilation valve in the stale store are also controlled using this “ throttle analyzer ” .

Development stageDifferent temperature are used in the storage of tulip bulbs . Before the flower development start , the bulbs have to be lay in at a changeless tender temperature . When setting the right temperature , the development stage of the blossom inside the lightbulb must always be determined first . There are six different stages , stage : I , II , P1 , A1 , A2 and G. Joost : “ Because only with this entropy you may determine the correct temperature and duration in the cold store . ”
