Kodi munayamba mwalowa mu greenhouse yanu m'mawa ndikumva ngati mukulowa mu sauna? Mpweya wofunda, wonyowawo ukhoza kuwoneka ngati wabwino kwa mbewu zanu - koma ukhoza kukupangitsani kuti muvutike.
Kuchuluka kwa chinyezi ndi chimodzi mwazomwe zimayambitsa matenda oyamba ndi fungus komanso kufalikira kwa tizirombo m'malo obiriwira. Kuchokera ku powdery mildew pa nkhaka kupita ku botrytis pa sitiroberi, chinyezi chochuluka mumlengalenga chimapanga malo abwino oberekera zovuta za zomera.
Tiyeni tifotokoze momwe mungasamalire chinyezi mu wowonjezera kutentha kwanu - ndi chifukwa chiyani kuchita izi kungapulumutse mbewu zanu ndi bajeti yanu.
Chifukwa Chiyani Chinyezi Chimafunika Mu Greenhouse?
Chinyezi ndi kuchuluka kwa nthunzi wamadzi mumpweya. Mu greenhouses, timalankhula kwambirichinyezi chachibale (RH) - ndi chinyezi chochuluka bwanji chomwe chili mumlengalenga poyerekeza ndi kuchuluka komwe kungathe kusunga kutentha kumeneko.
RH ikadutsa 85-90%, mumalowa m'dera langozi. Ndipamene tinjere za mafangasi zimamera, mabakiteriya amachulukana, ndipo tizilombo tina timakula bwino. Kuwongolera chinyezi ndikofunika kwambiri monga kusamalira kutentha kapena kuwala.
Mu wowonjezera kutentha kwanzeru ku Netherlands, masensa adachenjeza alimi pomwe RH idagunda 92%. Pasanathe maola 24, nkhungu yotuwa idawonekera. Tsopano amayambitsa mafani odziyimira pawokha ndi ma dehumidifiers pa 80% kuti akhale otetezeka.
Momwe Chinyezi Chochuluka Chimayatsira Matenda ndi Tizirombo
Matenda a fungal amakonda malo otentha, onyowa. Njere za powdery mildew, downy mildew, ndi botrytis zimangofunika maola ochepa chabe a chinyezi chambiri kuti ziyambike.
Chinyezi chochuluka chimalimbikitsanso:
Zomera zomata zomwe zimakopa thrips ndi whitefly
Kufooketsa mbewu minofu, kupangitsa matenda mosavuta
Condensation pamasamba, yomwe imafalitsa tizilombo toyambitsa matenda
Kukula kwa nkhungu pazipatso, maluwa, ngakhalenso makoma owonjezera kutentha
Ku Guangdong, wolima maluwa m'modzi adawona mawanga akuda akufalikira usiku wamvula. Wolakwa? Kusakaniza kwa 95% RH, mpweya wosasunthika, ndi kuzizira kwa m'mawa.
Gawo 1: Dziwani Chinyezi Chanu
Yambani poyezera. Simungathe kuwongolera zomwe simukuziwona. Ikani ma hygrometer a digito kapena masensa anyengo m'malo osiyanasiyana owonjezera kutentha kwanu - pafupi ndi mbewu, pansi pa mabenchi, ndi m'makona amithunzi.
Yang'anani:
Tsiku lililonse RH imakwera, makamaka dzuwa lisanatuluke
High RH m'madera otsika mpweya
Mwadzidzidzi spikes pambuyo ulimi wothirira kapena kutentha akutsikira
Masensa anzeru amatha kutsata RH ndikusintha mafani, ma vents, kapena ma foggers - kupanga nyengo yokhazikika.
Khwerero 2: Limbikitsani Mayendedwe a Air ndi Mpweya wabwino
Kuyenda kwa mpweya kumathandiza kuthyola matumba achinyezi. Imathandiziranso kuyanika masamba, zomwe zimalepheretsa bowa.
Malangizo ofunikira:
Ikani mafani a horizontal airflow (HAF) kuti azizungulira mpweya mofanana
Tsegulani denga kapena polowera m'mbali panthawi yotentha komanso ya chinyezi
Gwiritsani ntchito mafani otulutsa mpweya kapena chimneys kuti muchotse mpweya wonyowa
M'chilimwe, mpweya wabwino wachilengedwe ukhoza kuchita zodabwitsa. M'nyengo yozizira, sakanizani mpweya wotentha kuti muteteze kuzizira kwa zomera.
Wowonjezera kutentha wina ku California adachepetsa botrytis ndi 60% atakhazikitsa mapanelo olowera mpweya komanso mafani apansi.
Gawo 3: Sinthani Kuthirira Mwanzeru
Kuthirira kwambiri ndiye gwero lalikulu la chinyezi. Nthaka yonyowa imasanduka nthunzi, kukweza RH - makamaka usiku.
Malangizo othirira:
Madzi m'mawa kotero kuti chinyezi chochulukirapo chimauma pofika madzulo
Gwiritsani ntchito ulimi wothirira kuti muchepetse kutentha
Pewani kuthirira pa nthawi ya mitambo, masiku opanda kanthu
Chongani nthaka chinyezi pamaso kuthirira - osati pa ndandanda
Kusinthira ku masensa a chinyezi ndi kuthirira kwanthawi yake kunathandiza wolima tsabola wina ku Mexico kutsitsa RH ndi 10% kudutsa denga.
Khwerero 4: Gwiritsani Ntchito Dehumidifiers ndi Kutenthetsa Pamene Pakufunika
Nthawi zina, mpweya sikokwanira - makamaka nyengo yozizira kapena yamvula. Ma dehumidifiers amakoka chinyezi kuchokera mumlengalenga mwachindunji.
Phatikizani ndi Kutentha kwa:
Kupewa condensation pa wowonjezera kutentha makoma kapena kudenga
Limbikitsani kutuluka kwa zomera
Khalani ndi RH yokhazikika pafupifupi 70-80%
Kumadera akumpoto, kutenthetsanso mpweya wozizira wausiku kumalepheretsa chifunga cham'mawa ndi mame - zinthu ziwiri zazikulu zomwe zimayambitsa miliri ya mafangasi.
Nyumba zamakono zotenthetsera kutentha nthawi zambiri zimagwirizanitsa zochotsera chinyezi ndi zotenthetsera ku makompyuta anyengo kuti aziwongolera zokha.
Khwerero 5: Pewani Misampha Yobisika ya Chinyezi
Si chinyezi chonse chimachokera kumalo oonekera.
Samalani ndi:
Mwala wonyowa kapena pansi
Zomera zodzaza kwambiri zimatsekereza kuyenda kwa mpweya
Milu ya zinyalala za organic kapena nsalu zonyowa zamthunzi
Mapaipi otayira kapena mapaipi
Kusamalira nthawi zonse, kuyeretsa, ndi kusiya zomera zonse zimathandiza kuchepetsa "malo otentha".
Wowonjezera kutentha ku Vietnam adalowa m'malo mwa mulch wa pulasitiki ndi nsalu ya udzu wopumira ndikudula RH yake ndi 15% m'machubu otsika.
Khwerero 6: Phatikizani ndi machitidwe Ena a IPM
Kuwongolera chinyezi ndi gawo limodzi chabe la kupewa tizirombo ndi matenda. Kuti mutetezedwe kwathunthu, phatikizani ndi:
Ukonde wa tizilombo kuti tizirombo tisalowe
Misampha yomata yoyang'anira tizilombo touluka
Kuwongolera kwachilengedwe (monga nthata zolusa kapena bowa wopindulitsa)
Kuyeretsa nthawi zonse ndi kudulira mbewu
Njira yonseyi imapangitsa kuti wowonjezera kutentha wanu akhale wathanzi - ndikuchepetsa kudalira kwanu pa fungicides kapena mankhwala ophera tizilombo.
Chengfei Greenhouse imaphatikiza kuwongolera chinyezi munjira yawo ya IPM popanga ma modular mayunitsi okhala ndi mpweya wabwino womangidwira, ngalande, ndi masanjidwe a sensa - kuwonetsetsa kuti chinyontho chikukhazikika kuyambira pansi.
Kusunga bwino izi kumapangitsa kuti mbewu zanu zizikula mwamphamvu - komanso tizirombo ndi bowa.
Tsogolo la Kuwongolera Chinyezi
Kuwongolera chinyezi kukupita pa digito. Zida zatsopano zikuphatikiza:
Masensa opanda zingwe a RH amalumikizidwa ndi ma dashboards amtambo
Makina olowera / fan / fogger
Mapulogalamu a nyengo yoyendetsedwa ndi AI omwe amalosera za ngozi ya condensation
Zosintha zotenthetsera zosagwiritsa ntchito mphamvu zowongolera chinyezi m'nyengo yozizira
Ndi zida zoyenera, alimi tsopano ali ndi mphamvu zambiri kuposa kale lonse - komanso kupsinjika maganizo panthawi yamvula.
Mukufuna zomera zathanzi, mankhwala ocheperako, ndi zodabwitsa zochepa za tizirombo? Yang'anirani chinyezi chanu - chanuwowonjezera kutenthandidzakuthokozani.
Takulandilani kukambilananso nafe.
