Kusunga kutentha kwa wowonjezera kutentha m'munsi 35 ° C (95 ° f) ndikofunikira pakuwonetsetsa kukula koyenera ndikupewa zovuta zingapo zowonjezera kutentha. Ngakhale greeghouses imateteza ku nyengo yozizira, kutentha kwambiri kumatha kuvulaza kwambiri kuposa zabwino. Ichi ndichifukwa chake kusamalira kutentha kwanu wobiriwira ndikofunikira, komanso momwe mungathandizire mbewu zanu zikuyenda bwino!
1. Kutentha kwambiri kumatha kuthana ndi mbewu zanu
Zomera zambiri zobiriwira zambiri zimayenda bwino pakati pa 25 ° C ndi 30 ° C - 86 ° F). Mwachitsanzo, tomato, mbewu wamba wamba, imakula bwino pamanja, ndikupanga masamba athanzi ndi zipatso zapamwamba. Komabe, mukamaliza kutentha kupitirira 35 ° C, photosynthesis akanagwira ntchito mosavuta, masamba amatha kutembenukira chikasu, ndipo mbewu zitha kusiya maluwa. Izi zikachitika, mbewu zanu za phwetekere zimatha kulimbana ndi zipatso, zomwe zimapangitsa kukhala otsika komanso otsika mtengo.
2. Kutayika kwamadzi kumatha kusiya mbewu "ludzu"
Kutentha kwambiri kumatha kuyambitsa mbewu kuti zitaye madzi mwachangu kuposa momwe angazipewere. Pamene kutentha kukwera, mbewu zimayenda mwachangu kwambiri, kutaya madzi kuchokera masamba ndi dothi. Mu wowonjezera kutentha omwe ali oposa 35 ° C, izi zitha kuyambitsa mbewu zanu, ngati tsabola, kuthana ndi chinyezi ngati chinyezi cha dothi limatuluka mwachangu. Popanda madzi okwanira, masamba akhoza kuyamba kupindika, chikasu, kapena ngakhale dontho. Pankhaniyi, mbewu zanu zimasiyidwa "ludzu," ndipo zokolola zawo zonse zimakhudzidwa.
3. Kutentha kwatchera kumayambitsa kupsinjika
Greenhouse imapangidwa kuti igwire kuwala kwa dzuwa, koma popanda mpweya wokwanira, kutentha kumatha kupanga. Popanda mthunzi kapena mawonekedwe okwanira, kutentha kungafanane pamwamba pa 35 ° C, nthawi zina mpaka kufika pa 40 ° C (104 ° F). Pansi pa kutentha kwapamwamba kotero, mizu ya mbewu imatha kulimbana ndi mpweya wokwanira, pomwe masamba amatha kuwonongeka ndi kuwonongeka kwa kutentha. Mwachitsanzo, nkhaka ndi mbewu phwetekere zimawonekera kutentha kwambiri popanda kukhazikika pamizu kapena ngakhale kufa chifukwa cha kutentha kwa kutentha.
4. Kutentha kwambiri kusokoneza malo obiriwira zachilengedwe
Wowonjezera kutentha si nyumba kuzomera; Komanso ndi chilengedwe chokhala ndi matenda opatsirana, tizilombo tothandiza, komanso tizilombo tothandiza. Kutentha kwakukulu, kofunikira pollivators ngati njuchi kumatha kukhala osagwira ntchito, kusokoneza chomera chovunda. Ngati kutentha mu wowonjezera kutentha kukukwera pamwamba pa 35 ° C, njuchi kungalepheretse kupukutira, komwe kumachepetsa zipatso zopangidwa ngati tomato ndi tsabola. Popanda thandizo lawo, mbewu zambiri zimavutika kututa.
2. Kuyang'anira Kuwala: Maluwa amafunikira kuwala kokwanira kwa photosynthesis, koma kuwala kwambiri kumatha kuwononga mbewu. Mu greenhouses, mphamvu yopepuka imatha kukhazikitsidwa pogwiritsa ntchito maukonde a shade kuti awonetsetse kuti mabulosi opanda dzuwa sakuwoneka bwino kwambiri dzuwa. Makanema owoneka bwino amathanso kugwiritsidwa ntchito powonjezera kulimba kwambiri, makamaka nthawi yachisanu masana ndi achidule.
3. Mpweya wabwino ndi chinyezi: mpweya wabwino komanso chinyezi chowongolera mkati mwa wowonjezera kutentha ndizofunikiranso kukula kwa buluzi. Mpweya wabwino woyenera ungathandize kuchepetsa kutentha mkati mwa wowonjezera kutentha, kuchepetsa kuchuluka kwa tizirombo ndi matenda, komanso kukhala ndi chinyezi chabwino. Pa nthawi ya Blueberry Kukula, Mzere Wophunzira Mphepo Mkati mwa wowonjezera kutentha ayenera kusungidwa pa 70% -75%, yomwe ilipo, yomwe ili yabwino kubuluta.
5. Kugwiritsa ntchito mphamvu kwambiri komanso kukwera mtengo
Kutentha kwa greenhout kumakhala kukwera kwambiri, makina ozizira ngati mafani ndi zolakwika muyenera kugwira ntchito nthawi yowonjezera. Kugwiritsa ntchito mosalekeza kwa zida zozizira sikumangowonjezera ndalama zamagetsi komanso kuopsa kosautsana kapena kuwononga zida zokha. Mwachitsanzo, ngati wowonjezera kutentha amakhala pafupifupi 36 ° C m'chilimwe, machitidwe ozizira amatha kusiya kusanja, ndikuyendetsa mphamvu zanu ndi malo ogulitsira. Kusamalira kutentha bwino kumatha kuchepetsa kugwiritsa ntchito mphamvu ndikuwonjezeranso zida zanu.
6. Kutentha koyenera kwa zomera zathanzi, zachimwemwe
Zomera zobiriwira zambiri zimakula bwino pakati pa 18 ° C ndi 30 ° C - 86 ° F). Pa kutentha kumene, mbewu ngati sitiroberi, tomato, ndi nkhaka zimatha kukhala ndi zithunzi mokwanira, zomwe zimapangitsa kuti zokolola zambiri zizikhala bwino. Mwa kukhalabe ndi mtundu wabwinowu, mutha kuchepetsanso kufunika kozizira kwambiri, kuchepetsa mphamvu yanu ndikulimbikitsa kukula kwamitengo yathanzi.
Kusunga kutentha kwa wowonjezera kutentha m'munsi 35 ° C ndikofunikira kwa mbewu zanu zaumoyo ndi zokolola. Kutentha kwambiri kumatha kusokoneza photosychesis, kumathandizira kutayika kwa madzi, kusokoneza malo owonjezera kutentha zachilengedwe, ndikuwonjezera mphamvu. Pazolinga zabwino, cholinga chofuna kusunga wowonjezera kutentha pakati pa 18 ° C ndi 30 ° C, zomwe zimalola mbewu kuti zizitha bwino mukamachepetsa mtengo wosafunikira. Tsatirani malangizowa kuti mupatse mbewu zanu kukhala zabwino kwambiri.
