Kuluntu lwegadi, njengoko ubusika bujikeleza, "iintlobo zeelettuce zokulima i-greenhouse ebusika" iba ligama lokukhangela elidumileyo. Ngapha koko, ngubani ongafuni ukuba i-greenhouse yakhe izaliswe buhlaza obuchumileyo kwaye ivelise i-lettuce entsha nethambileyo ngexesha lokubanda? Namhlanje, makhe siphonononge ihlabathi lokulinywa kwelettuce yasebusika kwaye sifumanise ukuba zeziphi iintlobo ezisebenza ngokugqwesileyo.
I-Cold-Iintshatsheli ze-Hardy: Iilethisi ezingoyikiyo kwi-Cold
Kwiindawo zokugcina izityalo zasebusika, amaqondo obushushu aphantsi ngowona mngeni uphambili ekulinyweni kwe lettuce. Ilettuce ethi "Winter Delight", ngokuzala ixesha elide, inohlobo olubalaseleyo lokumelana nokubanda. Kwindlu yokukhulisela izityalo kuMntla-mpuma weTshayina, ubushushu bexesha lasebusuku buhamba phakathi kwe-2 - 6℃ kangangeentsuku ezilishumi ezilandelelanayo. Ngelixa iintlobo ze-lettuce eziqhelekileyo zayeka ukukhula, i-lettuce ethi "Winter Delight" yahlala igcwele amagqabi aluhlaza. Iiseli zayo zamagqabi ziqokelela isixa esikhulu sezinto zokunqanda umkhenkce ezifana neproline, ethoba indawo yokukhenkca yencindi yeseli, ithintele iiseli ekubeni zonakaliswe ngamaqondo obushushu aphantsi. Ngexesha lokuvuna, isivuno sayo sasingaphantsi kwe-12% ngaphantsi kweqondo lobushushu eliqhelekileyo, ngelixa isivuno seentlobo ze lettuce eziqhelekileyo zehla nge-45% - 55%, ebonisa umsantsa ocacileyo.
I-lettuce ethi "Cold Emerald" nayo inokumelana nokubanda okumangalisayo. Amagqabi awo ashinyeneyo agqunywe ngumaleko obhityileyo we-waxy ngaphezulu. Lo maleko we-waxy awunciphisi nje ukukhuphuka kwamanzi, ukugcina isityalo "sifumile", kodwa sisebenza njenge-insulation, sithintela umoya obandayo ekuhlaseleni ngokuthe ngqo izicubu zeqabunga zangaphakathi. Kwindlu eluhlaza e-Hebei, ngexesha lasebusika xa iqondo lobushushu lalihlala liguquguquka malunga ne-7℃, i-lettuce ye-"Cold Emerald" ikhule amagqabi amatsha ngokukhawuleza, kunye nesityalo esihlangeneyo kunye nesomeleleyo. Izinga lokusinda kwayo yayingama-25% - 35% ngaphezulu kuneentlobo eziqhelekileyo ze lettuce.
Iinkwenkwezi zeHydroponic: Ukuphumelela kwiZisombululo zeSondlo
Namhlanje, i-hydroponics iya ithandwa kakhulu ekulinyweni kwe-lettuce eluhlaza. Ilettuce ethi "Hydroponic Jade" inenkqubo yeengcambu ephuhliswe kakhulu kunye nekhono elimangalisayo lokuziqhelanisa nemekobume yasemanzini. Emva kokuba ifakwe kwinkqubo ye-hydroponic, iingcambu zayo zisasazeka ngokukhawuleza, zenza "inethiwekhi yokufunxa izondlo" ezinamandla ezinokuthi zithathe ngokufanelekileyo izondlo eziphambili ezifana ne-nitrogen, i-phosphorus, kunye ne-potassium kwisisombululo sezondlo. Ukuba nje iqondo lobushushu lilawulwa phakathi kwe 18 - 22℃ kwaye isisombululo sezondlo silinganiswe ngokuchanekileyo, sinokuvunwa malunga neentsuku ezingama-35. Kwi-Chengfei Greenhouse, ebusika, ngokulawula okusingqongileyo okunengqondo, i-lettuce "Hydroponic Jade" ityalwe kwinqanaba elikhulu. Indawo yokutyala enye ifikelela kwi-1500 square metres, kwaye isivuno ngesityalo ngasinye sigcinwa ngokuzinzileyo kwi-9 - 10 tons. Ilettuce evuniweyo inamagqabi amakhulu, akrwada, nanencindi enencasa eswiti enconywa kakhulu.
I-lettuce ethi "Crystal Ice Leaf" ikwayinkwenkwezi kwi-hydroponics. Amagqabi ayo agutyungelwe ngekristale - iiseli ezicacileyo ze-vesicular, ezingenzi nje ukuba zibukeke zintle kodwa zinyusa umthamo wayo wokugcina amanzi. Kwimekobume ye-hydroponic, iyakwazi ukuziqhelanisa ngokulula notshintsho lwezondlo kunye namanzi. Kwikhaya elincinci - isitayela se-hydroponic greenhouse eShanghai, izityalo ezingama-80 ze "Crystal Ice Leaf" zatyalwa. Umnini watshintsha isisombululo sezondlo ngexesha ngeveki kwaye wasebenzisa i-aerator ukuqinisekisa i-oksijini eyaneleyo echithwe emanzini. Ilettuce yakhula ngamandla. Ngexesha lokuvuna, ubunzima obuqhelekileyo besityalo ngasinye bufike malunga ne-320 grams, kunye namagqabi atyebileyo atyebileyo kwiiminerali ezahlukeneyo kunye neevithamini.
Izifo - Amaqhawe Axhathisayo: Ukuzikhusela Ngokulula kwiZifo
Iindawo zokuhlalazivalelwe ngokufuma okuphezulu, nto leyo "yiparadesi" yeentsholongwane. Nangona kunjalo, i-lettuce ethi "Isifo - I-Resistant Star" ayinaloyiko. Iqulethe i-metabolites eyahlukeneyo yesibini kwisityalo sayo, njenge-phytoalexins kunye ne-phenolic compounds. Xa iipathogens zihlasela, ngoko nangoko ivula indlela yayo yokuzikhusela. Kwindlu yokugcina izityalo kwindawo eselunxwemeni lwase Zhejiang, apho ubumanzi bebuphezulu unyaka wonke, izehlo ze-downy mildew kwiintlobo ze lettuce eziqhelekileyo zaziphezulu ukuya kuma-55% - 65%. Emva kokutyala i-lettuce "Isifo - I-Resistant Star", iziganeko zehla ukuya kwi-8% - 12%. Ebusweni be-downy mildew pathogens, i-phytoalexins kwi-lettuce ethi "Isifo - I-Resistant Star" inokuthintela ukuhluma kwe-pathogen spores kunye nokukhula kwe-hyphae, ukuthintela i-pathogens kwi-colonizing kunye nokusabalalisa kwisityalo. Ukusetyenziswa kwe-pesticides kuyancipha kakhulu, kwaye i-lettuce eveliswayo iluhlaza kwaye inempilo.
