Ifotoperiod yeyona nto ibalulekileyo yokudumba iintyatyambo

1. Iindidi zeempendulo zefotoperiod yezityalo

Izityalo zinokuhlulwa zibe zizityalo ezinde (isityalo sosuku olude, esifinyeziweyo njenge-LDP), izityalo zeentsuku ezimfutshane (isityalo esifutshane, esifinyeziweyo njenge-SDP), kunye nezityalo ezingathathi hlangothi (isityalo esingathathi hlangothi, esifinyeziweyo njenge-DNP) ngokohlobo lwempendulo kubude bokukhanya kwelanga ngexesha elithile lophuhliso.

I-LDP ibhekisa kwizityalo ekumele ukuba zinde kunenani elithile leeyure zokukhanya ngosuku kwaye zinokudlula inani elithile leentsuku ngaphambi kokuba zidubule. Njengengqolowa yasebusika, irhasi, i-rapeseed, i-Semen Hyoscyami, i-olive eswiti kunye ne-beet, njl., kunye nexesha elide lokukhanya, ukuqhakaza kwangaphambili.

I-SDP ibhekisa kwizityalo ekufuneka zibe ngaphantsi kwenani elithile leeyure zokukhanya ngosuku phambi kokuba zidubule. Ukuba ukukhanya kuncitshiswe ngokufanelekileyo, intyatyambo inokuqhubela phambili kwangaphambili, kodwa ukuba ukukhanya kwandiswa, ukudubula kweentyatyambo kunokulibaziseka okanye kungadubi. Njengerayisi, ikotoni, i-soya, icuba, i-begonia, i-chrysanthemum, uzuko lwasekuseni kunye ne-cocklebur njalo njalo.

I-DNP ibhekisela kwizityalo ezinokuqhakaza phantsi kwazo naziphi na iimeko zokukhanya kwelanga, ezifana netamatato, ukhukhamba, i-rose, kunye ne-clivia njalo njalo.

2. Imiba ePhambili ekuSetyenzisweni koMgaqo weFotoperiod yokuNtyamba kweeNttyatyambo

Ubude bosuku olubalulekileyo lwesityalo

Ubude bemini obubalulekileyo bubhekisa kobona kukhanya bude bemini obunokunyanyezelwa sisityalo sosuku olufutshane ngexesha lomjikelo wobusuku bobusuku okanye olona kukhanya lufutshane lwemini oluyimfuneko ukuphembelela isityalo sosuku olude ukuba sidubule. Kwi-LDP, ubude bosuku bukhulu kunobude bosuku olubalulekileyo, kwaye iiyure ezingama-24 zinokuqhakaza. Nangona kunjalo, kwi-SDP, ubude bosuku kufuneka bube ngaphantsi kobude bosuku obubalulekileyo bokudubula kweentyatyambo, kodwa bube bufutshane kakhulu ukuba bungatyatyamba.

Isitshixo seentyantyambo zezityalo kunye nolawulo olwenziweyo lwefotoperiod

Ukudubula kweentyatyambo ze-SDP kumiselwa bubude bexesha elimnyama kwaye akuxhomekekanga kubude bokukhanya. Ubude bokukhanya kwelanga obufunekayo ukuze i-LDP idubule abubude ngokuyimfuneko kunobude bokukhanya kwelanga obufunekayo ukuze i-SDP idubule.

Ukuqonda iintlobo eziphambili zeentyantyambo zezityalo kunye nempendulo ye-photoperiod kunokwandisa okanye ukunciphisa ubude belanga kwi-greenhouse, ukulawula ixesha leentyantyambo, kunye nokusombulula ingxaki yeentyatyambo. Ukusebenzisa iGrowook's LED Growpower Controller ukwandisa ukukhanya kunokukhawulezisa ukudumba kwezityalo zosuku olude, kunciphise ukukhanya, kwaye kukhuthaze ukudumba kwezityalo zosuku olufutshane kwangoko. Ukuba ufuna ukulibazisa ukudubula kweentyatyambo okanye ukungadumi, ungawubuyisela umva umsebenzi. Ukuba izityalo zexesha elide zilinywa kwiindawo ezitshatyalaliswayo, aziyi kudumba ngenxa yokungabikho kokukhanya ngokwaneleyo. Ngokufanayo, izityalo zeentsuku ezimfutshane ziya kulinywa kwiindawo ezipholileyo nezibandayo ngenxa yokuba aziyi kuqhakaza ixesha elide.

3. Intshayelelo kunye nomsebenzi wokufuya

Ulawulo olwenziweyo lwefotoperiod yezityalo lubaluleke kakhulu kwintshayelelo yezityalo kunye nokuzala. IGrowook ithatha ukuba wazi ngakumbi malunga neempawu zokukhanya kwezityalo. Kwi-LDP, imbewu evela emantla yaziswa emazantsi, kwaye iintlobo ezikhula kwangoko ziyafuneka ukulibazisa ukudubula kweentyatyambo. Okufanayo kuya kwiintlobo zasezantsi ukuya ngasentla, ezifuna iintlobo ezikhula emva kwexesha.

4. Ukuqaliswa kweentyatyambo nguPr kunye noPfr

Iifotosensitizers zifumana ikakhulu imiqondiso yePr kunye nePfr, echaphazela ukwenziwa kweentyatyambo kwizityalo. Isiphumo seentyatyambo asigqitywanga sisixa esipheleleyo sePr kunye nePfr, kodwa ngumlinganiselo wePfr / Pr. I-SDP ivelisa iintyatyambo ngokomlinganiselo ophantsi wePfr/Pr, ngelixa ukwakhiwa kwezivuseleli ze-LDP ezenza iintyatyambo kufuna umlinganiselo ophezulu wePfr/Pr. Ukuba ixesha elimnyama liphazanyiswa kukukhanya okubomvu, umlinganiselo wePfr / Pr uya kwanda, kwaye ukwakhiwa kweentyatyambo ze-SDP kuya kunyanzeliswa. Iimfuno ze-LDP kumlinganiselo we-Pfr / Pr azingqongqo njengezo ze-SDP, kodwa ixesha elide lokukhanya elaneleyo, i-irradiance ephezulu, kunye nokukhanya okubomvu kuyafuneka ukuphembelela i-LDP ukuba idubule.
