Varimi vanoda kuti vaongororwe zvekushandisa kwavo uye mvura inoyerera vanofanira kutora sample voitumira kurabhoritari. Vanobva vamirira mazuva mashoma kuti vawane mugumisiro. Nezvikonzero izvi, kuvhiya uku kunoitwa chete mazuva manomwe kusvika gumi nemana. Nekuyera mvura neion-specific mita in-situ, mugumisiro unozivikanwa munguva inenge awa, uye murimi anogona saka kugadzirisa pakarepo kana zvichidiwa. Uye zvakare, kusikwa kwedata in-situ kunosiya nzvimbo yeamangwana otomatiki ekugadzirisa. The Business Unit Greenhouse Horticulture uye Flower Bulbs yeWageningen University & Research iri kuongorora kushandiswa kunoshanda kweCeline, ion-yakananga midziyo yekuyera, uye kubatsirwa kwezvinonzi 'ion-specific kurima.'
Makore mashoma apfuura, Iyo Sensor Factory yakatanga iyo Celine, chishandiso chekuitisa ion-chaiyo zviyero zvinoshandisa hunyanzvi hwecapillary electrophoresis. WUR yakagadzira consortium kuti iongorore kuti Celine inogona kushandiswa sei uye kuvandudzwa. WUR ine chinangwa chekuunganidza ruzivo rwakakwana kuenzanisa ion-chaiyo kurima (ISC) (kugadziriswa kwezuva nezuva paion) zvichienderana neyakajairwa tsika (CC) (kugadziriswa kwemazuva ese paEC) uye kuratidza kugona kwepamusoro kweiyo yekare. ISC inofungidzirwa kuti inoderedza kushanduka kweion munzvimbo yemidzi kana ichienzaniswa neCC, iyo inogona kupedzisira yawedzera goho ne5%.
Rabhoritari bvunzo
Miedzo yeLabhoritari yakatanga kuitwa kuratidza mhedzisiro yekushanduka kweion pane goho. WUR yabva yamhanyisa muyedzo wekuenzanisa pakati peISC neCC, iyo, zvisinei, haina kuratidza kuwana kwakakosha kweISC nekuda kwekutadza kwehunyanzvi mukushandisa kuchinjika kwezuva nezuva kuISC. Muchokwadi, kushandisa kugadzirisa kwezuva nezuva, zvinodikanwa kubata fetiraiza jekiseni unit. Nekuda kwechikonzero ichi, ongororo yakazotevera muna 2021 pakambani inorima muriwo yeRoyal Pride, uye Celine parizvino iri kuongororwa nemurimi wemadomasi Kwekerij Lijntje, apo varimi vese vari vaviri vane majekiseni efotereza.
Chidzidzo chacho chinonyanya kutarisa macronutrients NH4, K, Ca, Mg, Na, NO3, Cl, SO4, PO4, uye HCO3. Zvose mvura yekudonha uye mvura yekudiridza inoongororwa. Izvo zvinoenda nepapombi kuenda kuCeline. Chiyero chacho saka chiri otomatiki; murimi, naizvozvo, haafaniri kutora sampuli. Munguva yekutsvaga, data pamusoro peiyoni inoiswa muWUR's nutrient recommendation program (NRP), iyo BAB (Bemesting Advies Basis), iyo inotsanangura iyo data kubva kuCeline uye inopa mazano ekugadzirisa zuva nezuva kumurimi.
Autonomous fertigation
Kushandiswa kweion-specific meter in-situ pamwe chete neNRP kunganyanya kufarirwa kune idzo nzvimbo dzine ruzivo rushoma pamusoro pefotereza uye kuongorora murabhoritari kunononoka kana kudhura zvakanyanya. Pane kudaro, kune mamwe emazuva ano greenhouses, musanganiswa uyu inhanho yekutanga kuenda kune yakazvimirira fertigation masisitimu.
Kuti uwane mamwe mashoko,
