Kana zvasvikagreenhousekukura kwechirimwa, zvinhu zvakaita setembiricha, mwando, uye chiedza zvinowanzova pamberi pepfungwa dzedu. Asi chimwe chinhu chisingambofaniri kufuratirwa imhepo. Ndicho chinhu chakakosha mukusimudzira kukura kwechirimwa chine hutano uye kuve nechokwadi chegoho repamusoro. Saka, zvinoita here kurima zvirimwa mu agreenhousepasina mhepo? Ngationgororei kuti nei kufefetera kuchikosha uye kuti kunobatsira sei zvirimwa kuti zvikure.
1. Nei UchidaroGreenhousesUnoda Ventilation?
Greenhousezvirimwa, sesu, zvinoda mweya mutsva kuti zvikure. Pasina kufefetedza kwakaringana, zvidyarwa zvako zvinogona kutarisana nenyaya dzakasiyana siyana, kusanganisira kushaikwa kweokisijeni, hunyoro hwakanyanya, uye kupisa. Heino chikonzero nei ventilation yakakosha:
* Oxygen Supply
Zvirimwa zvinotsamira pa photosynthesis kukura, kutora kabhoni dhaikisaidhi uye kuburitsa okisijeni. Kana kufefetera kusina kunaka, mazinga eokisijeni mukatigreenhouseinogona kudonha, ichikanganisa photosynthesis uye kuderedza kukura kwechirimwa.
Semuyenzaniso, mumwe murimi muUS akaona mashizha akatsvuka nekusvava nekuda kwekuderera kweokisijeni. Mushure mekuisa mahwindo ekufema, zvirimwa zvakakurumidza kupora uye zvakatangazve kukura zvine hutano.
* Humidity Control
Humidity management yakakosha mugreenhouses. Kunyorova kwepamusoro kunogona kutungamirira kune mold, fungal infections, uye zvimwe zvirwere zvezvirimwa. Kufefetera kunobatsira kubvisa mwando wakawandisa kubva mumhepo, kuchengetedza mwando mukutarisa uye kudzivirira zvirwere.
Mumwe murimi munzvimbo dzinopisa akatarisana nechinetso chakakomba chakuvhuvhu apo mwero wemvura wakakwira. Nekuwedzera kuburitsa mhepo, unyoro hwakaderedzwa, uye nyaya ye mold yakagadziriswa, zvichibvumira zvirimwa kuti zvibudirire zvakare.
* Heat Regulation
Munguva yezuva,greenhousesinogona kukurumidza kupisa, iyo inogona kusimbisa zvirimwa uye kunyange kukonzera kupisa kwemashizha kana kudonha kwemichero. Kufefetedza kunobatsira kuburitsa mhepo inopisa, kuchengetedza tembiricha mukati menzvimbo yakagadzikana yekukura kwechirimwa. Mumwe murimi muSpain aive nematembiricha anosvika 40°C nekuda kwekushaikwa kwemhepo, izvo zvakaita kuti zvirimwa zvematomatisi zvisvava. Mushure mekuisa mafeni ekupedza, tembiricha yakagadzikana, uye madomasi akadzokera kune hutano.
2. Chii Chinoitika kana aGreenhouseKushaya Ventilation?
Kana agreenhousehaina mhepo inofefetera, inogona kutungamira kumatambudziko akati wandei anokanganisa hutano hwezvirimwa uye kukura.
* Mhepo Yakamira
Pasina mhepo, carbon dioxide mazinga anogona kukwira uye mazinga eokisijeni anogona kudonha. Izvi zvinomisa photosynthesis uye zvinoderedza kukura kwechirimwa.
* Kuwedzera Ngozi yeChirwere
Kushaikwa kwemhepo yekufefetera kunogona kugadzira nharaunda yakakwana ye mold, mildew, uye mamwe hutachiona. Mhepo inomira, ine mwando inokurudzira zvirwere izvi, zvinogona kukurumidza kupararira nekukuvadza zvirimwa.
Mune imwegreenhousemuUK, hunyoro hwepamusoro uye mhepo isingachinjiki yakakonzera kuvhuvhuta pamastrawberries. Mushure mekunge mhepo yekufema yavandudzwa, dambudziko rakagadziriswa, uye zvirimwa zvakatanga kukura zvine hutano zvakare.
* Heat Stress
Kana agreenhousekunopisa zvakanyanya, zvirimwa zvinogona kusangana nekushushikana kwekupisa, izvo zvinotungamira kumatambudziko senge kudonha kweshizha, kusakura zvakanaka kwemichero, kana kufa. Ventilation inobatsira kudzinga kupisa kwakanyanya, kudzivirira nyaya idzi.
3. Mhando dzeGreenhouseVentilation
Pane nzira dzakati wandei dzekuburitsa mweya agreenhouse,uye mhando yaunosarudza zvinoenderana nehukuru hwenyugreenhouse,mamiriro ekunze enzvimbo, uye zvirimwa zvauri kukura.
* Natural Ventilation
Kufefetedza kwechisikigo kunotsamira pakufamba kwemhepo kusingaite, senge mahwindo, mamhepo, kana kuvhurika kwedenga. Mhepo inodziya inokwira uye inobuda nepadenga remba, nepo mhepo inotonhorera ichipinda nemumapasi. Iyi sisitimu inotsamira pane mhepo uye tembiricha kusiyana kuchengetedza kuyerera kwemhepo.
* Kumanikidzirwa Kufefetera
Zvekurisagreenhouseskana mamiriro ekunze asina mhepo yekufema yakakwana, kumanikidzira kufefetera isarudzo. Izvi zvinoshandisa mafeni kushingaira kusundira mweya unopisa kunze kwegreenhouse,kubvumira mweya unotonhorera kupinda uye kutenderera.
Mumwe murimi wekutengesa muCanada akaisa exhaust hombe uye mafeni ekudya kuti mweya urambe uchiyerera mukati mavogreenhouse,kuchengetedza nharaunda yakagadzikana yezvirimwa zvavo.
* Automated Ventilation
Vazhinji vemazuvanogreenhousesshandisa otomatiki masisitimu anogadzirisa kufefetera zvichibva pane chaiyo-nguva tembiricha uye humidity data. Aya masisitimu anogona kuvhura otomatiki mavhavha kana kumisa mafeni kuti achengetedze akakwana ekukura mamiriro pasina kupindira kwemaoko.
4. Inogona aGreenhouseKubudirira Pasina Ventilation?
Zvinogoneka nehunyanzvi kukura mu agreenhousepasina ventilation system, asi pane zvinhu zvishoma zvekufunga.
* DikiGreenhouses
Kana uine dikigreenhousenezvinomera zvishoma, zvinokwanisika kubata nharaunda nemaoko nekuvhura mahwindo kana kugadzirisa mavhavha. Nekudaro, zvinoda kugara uchitarisisa tembiricha, hunyoro, uye mafambiro emhepo kuitira kuti zvirimwa zvirambe zvine hutano.
* Mamiriro ekunze anotonhorera
Kana uri kukura munzvimbo inotonhorera, zvinodiwa zvekufefetera zvinogona kunge zvakaderera. Nekudaro, iwe uchiri kufanirwa kutarisa mhando yemhepo nguva nenguva kudzivirira kumira kwemweya kuvaka.
* High-DemandGreenhouses
Pamabasa makuru ekutengeserana kana mbesa dzinodiwa zvakanyanya sematomatisi kana magaka, chirongwa chemhepo chakagadzirwa zvakanaka chakakosha. Pasina iyo, zvirimwa zvako zvinogona kutambura nekusakura zvakanaka uye zvirwere.
5. Maitiro eKuvandudza Kufefetera muWakoGreenhouse?
Kana iwe usingakwanise kuisa yakaoma ventilation system, kuchine nzira dziri nyore dzekuvandudza kuyerera kwemhepo mune yakogreenhouse.
* Wedzera Mamwe Vents
Kuwedzera huwandu hwemavhavha padenga kana mativi egreenhousezvichabatsira mhepo kutenderera zvakanyanya uye kuderedza humidity mwero.
* Shandisa Shade Nets
Kuisa mambure emumvuri kunogona kuderedza kuwanda kwezuva rakananga kupinda mukatigreenhouse,kuderedza tembiricha uye kuderedza kudiwa kwemhepo yakakura.
* Yakakodzera Plant Spacing
Kuronga zvirimwa nenzira inobvumira nzvimbo yakakwana ichaita kuti mhepo ikwanise kuyerera zvakasununguka pakati padzo, kudzivirira humidity kuvaka-up. Mumwe murimi akawedzera mavhavha epadenga uye akashandisa mambure emumvuri kuderedza kuwanda kwekupisa. Aya matanho akareruka akabatsira kugadzirisagreenhouse'snharaunda, kuchengetedza zvirimwa zvine utano uye zvinobereka.
Ventilation ndiyo Kiyi yeGreenhouseUtano
Mukupedzisa, kufefetera chinhu chakakosha chegreenhouseutariri husingambofaniri kufuratirwa. Kunyangwe iwe uri kushanda nediki hobbygreenhousekana basa guru rekutengeserana, kuchengetedza mhepo yakakodzera kunokosha kune utano hwemiti. Nekusimbisa yakogreenhouseine hurongwa hwekufemesa mhepo hwakakodzera, iwe uchagadzira nharaunda yekukura yakakwana yezvirimwa zvako, zvichitungamira kune goho repamusoro uye zvirimwa zvine hutano.
