The project ‘ Monitoring energy innovations in practice ’ of Kas als Energiebron is , among other thing , looking for a relationship between the appearance of transmission line in alstroemeria and the cooling down of the crop as a result of eradiation . So far , a immobile conclusion can not be drawn .
The project ‘ monitor energy founding in practice session ’ aims to attain energy - effective horticultural production by acquiring and sharing knowledge about the impact of various energy - relieve measures on the nursery clime , the use of vim , the craw growth and the company performance .
Within this monitoring project , a clime comparability was started at the beginning of 2019 between four alstroemeria growers ( five department ) under the supervision of the Flori Consult Group and Wageningen University & Research Greenhouse Horticulture . The aim of this compare is to explain a physiologic freakishness that threaten the leaf quality : lily-white railway line in the foliage . The idea is that the nursery climate , and especially the industrial plant temperature fluctuations and eradiation , could be the crusade of this phenomenon . The presence of lines is tracked weekly and pass on by the companies themselves .
Involved companiesThree of the participating companies have a individual screenland ; one company has two screens . There are also differences in cultivation substrate : one company grows on coco , the three other companies in land . There is a section with a greenhouse roof of diffuse field glass . All company grow sensitive cultivars .
The agriculturist have buy extra sensing element for this research , such as a radiation therapy meter and measure box seat . A thermal imagination photographic camera has also been installed at every raiser . Furthermore , every grower has take out a LetsGrow subscription to easily deal the climate data . The agriculturist satisfy each other about once every six weeks to hash out the state of the crop and to discuss the differences between them .
AnalysisStripes were reported on several Clarence Day in April , May , July , August , September and even in October . Next , an psychoanalysis was made of the climate during the days prior to the news report and simulations with the ‘ radiation monitor ’ tool . So far it has not been potential to establish a substantial family relationship between the appearance of chevron and the temperature reduction of the harvest resulting from the eradiation .
The cultivator with two screens is still scathe - spare . Other differences between the raiser with and without damage that may play a persona are the cultivation in the filth or on substratum and the origin of the CO2 . The CO2 concentration can be high when windows are closed . There are also large fluctuations in humidity within a daytime .
