Ngaba unqwenela i-lettuce entsha ngexesha leenyanga ezibandayo zasebusika? Subanexhala! Ukukhulisa i-lettuce kwi-greenhouse kunokuba ngamava anomvuzo kwaye amnandi. Landela esi sikhokelo silula ukuze ube yingcali yokulima iletisi yasebusika.
Ukulungisa umhlaba ukulungiselela ukutyalwa kweGreenhouse yaseBusika
Umhlaba sisiseko sokukhula kwelethisi esempilweni. Khetha umhlaba ovunduvundu, otyebileyo oyisanti okanye oluvunduvundu. Olu hlobo lomhlaba lukwazi ukungena emoyeni, luvumela iingcambu ze lettuce ukuba ziphefumle ngokukhululekileyo kwaye zithintele ukugcwala kwamanzi. Yongeza i-3,000-5,000 yeekhilogram zesichumiso esibolile kakuhle kunye ne-30-40 yeekhilogram zesichumiso esixutywe ngehektare nganye. Xuba isichumiso kakuhle emhlabeni ngokulima ubunzulu obuziisentimitha ezingama-30. Oku kuqinisekisa ukuba i-lettuce ifumana zonke izondlo ezifunekayo kwasekuqaleni. Ukugcina umhlaba wakho usempilweni kwaye ungenazinambuzane, wuphathe ngomxube we-50% ye-thiophanate-methyl kunye ne-mancozeb. Eli nyathelo liza kudala indawo ecocekileyo nesempilweni ukuze i-lettuce yakho ikhule.
Ukongeza i-Insulation eyongezelelweyo kwi-Greenhouse ngexesha lasebusika
Ukugcina i-greenhouse yakho ishushu kubalulekile ebusika. Ukongeza iileya ezongezelelweyo zokugquma kungenza umahluko omkhulu. Ukwandisa ubukhulu be-greenhouse cover yakho ukuya kwi-5 centimeters kunokunyusa ubushushu ngaphakathi kwi-3-5 degrees Celsius. Kufana nokunika i-greenhouse yakho ingubo engqindilili, epholileyo ukuze ungabandi. Unokufaka kwakhona amakhethini e-insulation aphindwe kabini emacaleni nangaphezulu kwe-greenhouse. Oku kunokunyusa iqondo lobushushu ngenye idigri ezi-5 ngokukaCelsius. Ukuxhoma ifilimu ebonakalisayo kudonga olungasemva yenye intshukumo elumkileyo. Ibonisa ukukhanya kwakhona kwi-greenhouse, inyusa ukukhanya kunye nokufudumala. Ngezo ntsuku zibandayo, cinga ukusebenzisa iibhloko zokufudumeza, izifudumezi ze-greenhouse, okanye iziko lomoya elifudumeleyo eliqhutywa ngamafutha. Ezi zixhobo zinokuhlengahlengisa ngokuzenzekelayo ubushushu, ziqinisekisa ukuba i-greenhouse yakho ihlala ishushu kwaye ilungele ukukhula kwe lettuce.
I-pH kunye ne-EC yokuHlola iNqanaba leHydroponic Lettuce eBusika
Ukuba ukhulisa i-lettuce nge-hydroponically, ukugcina iliso kumanqanaba e-pH kunye ne-EC yesisombululo sakho sezondlo kubalulekile. I-lettuce ikhetha izinga le-pH phakathi kwe-5.8 kunye ne-6.6, kunye noluhlu olufanelekileyo lwe-6.0 ukuya kwi-6.3. Ukuba i-pH iphezulu kakhulu, yongeza i-ferrous sulfate okanye i-monopotassium phosphate. Ukuba iphantsi kakhulu, intwana yamanzi ekalika iya kwenza iqhinga. Jonga i-pH ngeveki ngemicu yovavanyo okanye imitha ye-pH kwaye wenze uhlengahlengiso njengoko kufuneka. Inqanaba le-EC, elilinganisa ukuxinwa kwezondlo, kufuneka libe phakathi kwe-0.683 kunye ne-1.940. Kwi-lettuce encinci, jolise kwinqanaba le-EC le-0.8 ukuya kwi-1.0. Njengoko izityalo zikhula, unako ukwandisa ukuya kwi-1.5 ukuya kwi-1.8. Lungisa i-EC ngokongeza isisombululo sezondlo ezigxininisiweyo okanye ukuhlambulula isisombululo esele sikhona. Oku kuqinisekisa ukuba i-lettuce yakho ifumana isixa esifanelekileyo sezondlo kwinqanaba ngalinye lokukhula.
Ukuchonga kunye nokuNyanga iiPathogens kwiLettuce yeGreenhouse ngexesha lasebusika
Ukufuma okuphezulu kwizindlu zokugcina izityalo kunokwenza i-lettuce ibe lula kwizifo. Gcina iliso kwimiba eqhelekileyo efana ne-downy mildew, ebangela ukungunda okumhlophe kwindawo engaphantsi kwamagqabi kunye nokuba tyheli; ukubola okuthambileyo, okukhokelela ekufakweni kwamanzi, iziqu ezivumbayo; kunye nokungunda okungwevu, okwenza ukungunda okungwevu emagqabini nakwiintyatyambo. Ukuthintela ezi ngxaki, gcina ubushushu obuphakathi kwe-15-20 ngokukaCelsius kunye nokufuma kwi-60% -70%. Ukuba ubona naziphi na iimpawu zesifo, nyanga izityalo ngesisombululo esixutywe amaxesha angama-600-800 se-75% ye-chlorothalonil okanye isisombululo esixutywe amaxesha angama-500 se-58% ye-metallaxyl-manganese zinc. Tshaza izityalo rhoqo ngeentsuku ezi-7 ukuya kwezi-10 kwizicelo ezi-2-3 ukugcina iintsholongwane zingekho kwaye i-lettuce yakho isempilweni.
Ukukhulisa i-lettuce kwi-greenhouse ngexesha lasebusika yindlela enhle yokonwabela imveliso emitsha kunye nokuzonwabisa egadini. Landela la manyathelo, kwaye uya kuvuna i-lettuce epholileyo, entsha nakwiinyanga ezibandayo.
