Polyethylene firimu ine matema anobatsira. Part Two.

Munyaya yapfuura takataura pamusoro ndechokuti rouchenjeri polyethylene firimu rave vakabudirira richishandiswa sechinhu kavha zvinhu muminda siyana. Zvino isu kujekesera iwe panyaya pokushandisa firimu Miracle mune dzimwe nzvimbo yebasa kwevanhu - kurima.

Mumwe pevara huru yematenga-rouchenjeri firimu mune zvokurima rinogona kunzi urwise kunowanzotangira uye greenhouses. Glass mapuranga kuti kare anodzivirira girinihausi inorema uye zvinodhura, ikozvino havana kufanana nevakawanda sepakutanga. Gadza girazi furemu hakusi nyore, asi girazi pacharo kazhinji anorova nezvikonzero zvakasiyana-siyana, kubvira siyana zvinhu vakauya nemhepo, nechimvuramabwe, vanhu chinhu. The kwaita yakakodzera uye nyore chokufuka mashoko greenhouses uye greenhouses - chimwe paiva casing zvinhu polyethylene firimu uyewo asingagamuchiri matambudziko akawanda. Under zvavo firimu kutonhora kunyange kupfuura pasi girazi, firimu yakabvaruka uye kurasikirwa nayo kwechinguva kana maviri mwaka.

Air dhudhumira firimu akapfuura zvakakwana mari ultraviolet mwaranzi kupinda girinihausi uye anochengeta kugara mhepo tembiricha mukati inokudza, kudzivirira Ndinoda yakasimbiswa zvinomera. Kunyange munhuwo dhudhumira foil pamwe matema vane dhayamita 25 mm uye kukwirira 8 mm, ane chete kuputira sezvo marongera ezvidhinha. With yakaderera uremu zvichienzaniswa girazi uye simba dzakakwirira achienzaniswa rimwe-rukoko polyethylene firimu iri panguva iyoyo, 80 nguva kunobatsira kupfuura girazi, uye 120 nguva kunobatsira kupfuura zvavo polyethylene firimu achadzivirira mizambiringa yakabva kumwe yenyu vakasimwa girinihausi kana glasshouse nechando kuti kuburikidza kuputira kukuru yaingowanikwa nayo. Sezvo zvechokwadi, maererano nemamiriro mhando sekanguva girazi, zvichiita nyore uye kusanduka insulating rinoonekera. Uchishandisa tembiricha siyana kubva kubvisa 60 kuwedzerazve 80 madhigirii umo rinogona kuramba ehupfumi dzavo rinobvumira mhoni firimu kudzivirira yakavimbika zviri hothouses uye kunowanzotangira tembiricha kuchinja.

Uyezve, kana anoumbwa mhepo-rouchenjeri firimu rine chaiyo chiedza Kudzikamiswa yokuvirisa izvo kuvandudza ehupfumi ayo, kudzivisa kudzikisirana kuti polyethylene yokuwana ultraviolet nemwaranzi uye saka mazhinji kushandiswa kwayo kunze kusvika makore mashanu, kushandiswa gore rose. With zvose izvi zvakadaro mhepo rouchenjeri firimu transmits 82 muzana zuva ultraviolet mwaranzi zvakafanira kuti kukura zvakanaka uye fruiting zvinomera wakasimwa, zvinofanira kucherechedzwa kuti girazi anopedza ndoda chiedza chezuva. A yakafanana chiedza-chaiyo chirungiso aripo rinokosha girinihausi firimu vatendeuki zuva chiedza uye hakubvisi nemwaranzi hurongwa ayo zvakaipa kukanganisa chirimwa. Chimwe chirungiso anobatsira girinihausi firimu anganzi chaiwo hydrophilic chirungiso (Antifog), muRugwaro zvirimo yomukati rukoko yakadaro firimu sefuro. Akaumba pamusoro yomukati hukawanika ose greenhouses uye hothouses makuru madonhedza yaiitwa yakapfupikiswa mvura kuva chikonzero kuderedza chiedza transmittance. Uyezve mvura mumate pamusoro firimu pamusoro kutarisa Mwaranzi yezuva, zvichiita vanonzi "izvo zvazviri" izvo hunokonzera chafariz kuvhunduka zvinomera. Antifog anobatsira kubvisa paumbwe hombe mumate dzemvura condensate, dzinovimbisa yunifomu aparadzirwe mvura firimu nhete rukoko. Mvura vakagovera noruvara pamusoro pemvura firimu uye zvishoma nezvishoma runoyerera pasi muvhu pakudaro kunoderedza mukana wokuti miti sunburn kubvisa vanonzi "izvo maturo".

Kwakadaro mhepo dhudhumira firimu rinoshandiswa sezvo maindasitiri kurimwa nemiriwo nemichero, uye kunyanya kushandiswa mumusha mapindu. Kana ukashandisa mhepo-rouchenjeri firimu vose kuwedzera izvi kuna girinihausi ake, mugumisiro akanaka ezvinhu kuti chirimwa negoho kunogona yakawedzera kusvika kaviri, uye mwero muchero ichiibvira imwe kana mbiri mavhiki.

Muzvirevo chikamu ichi uye takataura pamusoro pokushandiswa mhepo rouchenjeri firimu kuti kavha uye mune zvokurima. Munyaya inotevera tichataura pamusoro dzimwe mafomu mhoni AKAITA.
