1. Izinhlobo zempendulo ye-Plant photoperiod
Izitshalo zingahlukaniswa zibe izitshalo zosuku olude (isitshalo sosuku olude, esifushanisiwe njenge-LDP), izitshalo zezinsuku ezifushane (isitshalo sosuku olufushane, esifushanisiwe njenge-SDP), nezitshalo ezingathathi hlangothi (isitshalo esingathathi hlangothi, esifushanisiwe njenge-DNP) ngokohlobo lokusabela kubude bokukhanya kwelanga ngesikhathi esithile sokukhula.
I-LDP ibhekisela ezitshalweni okufanele zibe zinde kunenani elithile lamahora okukhanya ngosuku futhi ezingadlula inani elithile lezinsuku ngaphambi kokuba ziqhakaze. Okufana nokolweni wasebusika, ibhali, i-rapeseed, isidoda se-Hyoscyami, umnqumo omnandi nesithombo sebhitrudi, njll., futhi uma isikhathi eside sokukhanya, izimbali ziqala ukuqhakaza.
I-SDP isho izitshalo okufanele zibe ngaphansi kwenani elithile lamahora okukhanya ngosuku ngaphambi kokuba ziqhakaze. Uma ukukhanya kufinyezwa ngokufanelekile, ukuqhakaza kungathuthukiswa kusenesikhathi, kodwa uma ukukhanya kunwetshwa, ukuqhakaza kungabambezeleka noma kungaqhakazi. Okufana nelayisi, ukotini, ubhontshisi wesoya, ugwayi, i-begonia, i-chrysanthemum, inkazimulo yasekuseni kanye ne-cocklebur njalonjalo.
I-DNP ibhekisela ezitshalweni ezingaqhakaza ngaphansi kwanoma yiziphi izimo zokukhanya kwelanga, njengotamatisi, ukhukhamba, i-rose, ne-clivia nokunye.
2. Izinkinga Ezibalulekile Ekusetshenzisweni Kokulawulwa Kwezithombe Zezimbali Zezitshalo
Ubude bosuku olubalulekile lwezitshalo
Ubude bosuku olubalulekile bubhekisela ekukhanyeni kwemini okude kakhulu okungabekezelelwa isitshalo sosuku olufushane phakathi nomjikelezo wobusuku bobusuku noma ukukhanya okufushane kwemini okudingekayo ukuheha isitshalo sosuku olude ukuthi siqhakaze. Ku-LDP, ubude bosuku bukhulu kunobude bosuku olubucayi, futhi ngisho namahora angu-24 angaqhakaza. Kodwa-ke, ku-SDP, ubude bosuku kufanele bube buncane kunobude bosuku obubalulekile ukuze buqhakaze, kodwa bube bufushane kakhulu ukuba buqhakaze.
Ukhiye wokuqhakaza kwezitshalo nokulawula okwenziwe nge-photoperiod
Ukuqhakaza kwe-SDP kunqunywa ubude benkathi emnyama futhi akuncikile kubude bokukhanya. Ubude bokukhanya kwelanga obudingekayo ukuze i-LDP iqhakaze abubude ngempela kunobude bokukhanya kwelanga obudingekayo ukuze i-SDP iqhakaze.
Ukuqonda izinhlobo ezibalulekile zokuqhakaza kwezitshalo kanye nokuphendula kwe-photoperiod kunganweba noma kunciphise ubude bokukhanya kwelanga ku-greenhouse, kulawule isikhathi sokuqhakaza, futhi kuxazulule inkinga yokuqhakaza. Ukusebenzisa Isilawuli Sokukhulisa Amandla e-Growook se-LED ukuze kunwebe ukukhanya kungasheshisa ukuqhakaza kwezitshalo zosuku olude, kufinyeze ukukhanya ngempumelelo, futhi kukhuthaze ukuqhakaza kwezitshalo zezinsuku ezifushane kusenesikhathi. Uma ufuna ukubambezela ukuqhakaza noma ukungaqhakazi, ungahlehlisa ukusebenza. Uma izitshalo zezinsuku ezinde zilinywa ezindaweni ezishisayo, ngeke ziqhakaze ngenxa yokuntuleka kokukhanya. Ngokufanayo, izitshalo zezinsuku ezifushane zizotshalwa ezindaweni ezipholile nezibandayo ngoba ngeke ziqhakaze isikhathi eside.
3. Umsebenzi wokungenisa nokuzalanisa
Ukulawulwa kokwenziwa kwe-photoperiod yezitshalo kubaluleke kakhulu ekuqalisweni kwezitshalo nokuzalanisa. I-Growook ikuthatha ukuthi wazi kabanzi mayelana nezici zokukhanyisa izitshalo. Ku-LDP, imbewu evela enyakatho yethulwa eningizimu, futhi izinhlobo ezisheshe zivuthwe ziyadingeka ukuze kubambezeleke ukuqhakaza. Okufanayo kuya ezinhlotsheni eziseningizimu enyakatho, okudinga izinhlobo ezikhula sekwephuzile.
4. Ukwethulwa kwembali nguPr noPfr
Ama-photosensitizer athola amasignali e-Pr kanye ne-Pfr, athinta ukwakheka kwezimbali ezitshalweni. Umphumela wokuqhakaza awunqunywa inani eliphelele le-Pr ne-Pfr, kodwa ngesilinganiso se-Pfr / Pr. I-SDP ikhiqiza izimbali ngesilinganiso esiphansi se-Pfr / Pr, kuyilapho ukwakheka kwe-LDP eyenza izimbali kudinga isilinganiso esiphezulu se-Pfr / Pr. Uma isikhathi sobumnyama siphazanyiswa ukukhanya okubomvu, isilinganiso se-Pfr / Pr sizokhuphuka, futhi ukwakheka kwembali ye-SDP kuzocindezelwa. Izidingo ze-LDP esilinganisweni se-Pfr / Pr aziqinile njengalezo ze-SDP, kodwa isikhathi sokukhanya eside esanele, ukukhanya okuphakeme kakhulu, nokukhanya okubomvu kakhulu kuyadingeka ukuze kubangele i-LDP ukuthi iqhakaze.
