Firimu yakawanda-span greenhouse ndeimwe yeanonyanya kushandiswa greenhouse yekuvharisa zvinhu mukugadzira zvekurima, uye mashandisirwo ayo ezuva nezuva anotangira echinyakare mu-ivhu arches, chiedza chezuva greenhouses, kaviri-sided slope greenhouses, akawanda-span mafirimu greenhouses, uye fungus greenhouses. Saka varimi vekurima, kunyanya varimi vatsva, vangasarudza sei firimu regreenhouse rakakodzera pavanenge vachiita zvekurima, nhasi ndichakupa sumo pfupi uye kugovera.
Nhanho yekusimudzira yefirimu yegreenhouse Parizvino, chimiro chegreenhouse firimu chigadzirwa chinofanirwa kuvandudzwa kuti chiite multi-layer composite, uye kuita kunenge kuri kutapurirana kwechiedza chepamusoro, kuchengetedza kupisa kwakanyanya, simba rakakura, hupenyu hurefu uye nguva inoramba ichidonha, nguva yekurwisa mhute, nguva isina guruva, uye mamwe mabasa. Integrated development. Kuvandudzwa kwefirimu regreenhouse kwakawanzopfuura nematanho mana maererano nemhando dzakasiyana dzekugadzira: yekutanga ipolyethylene (PE) greenhouse film; yechipiri inonzi polyvinyl chloride (PVC) greenhouse film; yechitatu ndeye ethylene-vinyl acetate copolymer (EVA) greenhouse film; yechina iPO firimu, uye yechishanu-chizvarwa shanu-layer co-extruded firimu pasi pekuvandudzwa.
Iwo makuru maficha uye mutsauko weakasiyana greenhouse mafirimu:
1. PVC (polyvinyl chloride) greenhouse film. Iyi firimu ine yakanaka transmittance yechiedza, iyo firimu nyowani ine yakazara mwenje transmittance inopfuura 85%, yakanakisa kuchengetwa kwemwando, yakaderera yekupisa conductivity, kusimba kwakanyanya, uye yakasimba mhepo kuramba. Kugadzikana kwakanaka kwemakemikari, asidhi uye alkali kuramba. Izvo zvisingabatsiri ndezvokuti firimu rine chikamu chikuru, uye kushandiswa kwenzvimbo imwechete yeiyo greenhouse ndeye 1/3 kupfuura iyo ye polyethylene, zvichiita kuti kuwedzerwa kwemari; chechipiri, inova yakaoma uye inoputika pakupisa kwakadzika, uye zviri nyore kupfava uye kuzorora pakupisa kukuru; mushure mekunge zvinowedzerwa zvanaya, iyo firimu pamusoro Kuunganidzwa kweguruva, mwenje wekufambisa kazhinji hauna kunaka mushure memwedzi mumwe wekushandiswa. Iyo firimu yakasara inosvibisa ivhu uye haigoni kupiswa. Nekuda kwekusvibiswa kwezvakatipoteredza kunokonzerwa nekugadzirwa kweklorini, kushandiswa kwazvino kuri kuderera zvishoma nezvishoma.
2. PE greenhouse firimu.PE greenhouse firimuyakapfava mukugadzirwa, yakapfava, iri nyore kuumba, yakanaka mukufambiswa kwechiedza, isiri-chepfu, inokodzera akasiyana-siyana egreenhouse mafirimu uye mulching mafirimu, uye parizvino ndiyo huru yekurima firimu siyana munyika yangu. Zvinoenderana nezvinodiwa nevarimi, mhando dzakasiyana dzezvigadzirwa zvakaita sePE anti-kuchembera (kudzivirira kamwe chete), PE anti-kuchembera kudonha (kudzivirira kaviri), PE anti-kuchembera inodonha anti-fogging (matatu anti-fogging) anogona kugadzirwa, aine zvakanaka anti-kuchembera uye drip anti-fogging sex. Kuipa kwayo ndeichi: kusamira zvakanaka kwemamiriro ekunze, kusachengetedza kupisa kwakashata, uye kunetsa kubatanidza. Maneja Rwiyo akadzidza kuti PE grouting firimu rinonyanya kushandiswa mumusika.
3. Iyo grouting firimu inogadziriswa zvakare pahwaro hwepakutanga polyethylene firimu, uye mukati mukati meiyo yekurima firimu inobatwa nekuputira, kuitira kuti iyo inobatwa firimu ine inoshanda inodonha antifogging agent yakasungirirwa pairi. Pachidziro chemukati chefirimu yakadururwa, mushonga wezvinodhaka unoumbwa pamusoro pemukati wefirimu yakadururwa. Pangosvika mwando mushedhi uchibata mukati memadziro emufirimu rakateurwa, firimu remvura richaumbwa, uye rinoyerera richidzika nemateru eshedhi nekuda kwesimba rayo, kuitira kuti riwane mhedzisiro yekubvisa. mhute nekudonha. Musiyano wakakosha neyakapfuura greenhouse firimu ndeyekuti inoshanda mumiriri iripo yakazvimirira yegreenhouse firimu, saka nguva yeanti-fogging uye kudonha mabasa inoenderana zvachose nekutonga kwekupfeka, kunaka kweiyo coating agent uye kushandiswa kwe. firimu rekurima. Urefu hwehupenyu hunogona kusvika kupfuura gore rimwe chete.
Ehe saizvozvo,grouting filmanewo hurema hwega. Kutanga, iyo inopesana nemhute inodonha mumiriri inosungirirwa pamusoro pefirimu rekurima, saka kunamatira kwayo hakuna kusimba zvakanyanya. Simba rekunze riri nyore kukonzeresa kukuvadza kwekuputira, kuitira kuti zvive nyore kukonzera kudonha munzvimbo yakakuvadzwa. Semuenzaniso, apo shedhi, kupokana pakati pemadziro emukati meshedhi nemapango eshenjere pashedhi, mamiriro ataurwa pamusoro achaitika apo zvirimwa zvakakwirira zvinosangana nefirimu rekurima. Panguva imwecheteyo, hazvisi nyore kushandisa grout firimu kune zvirimwa zvinoda kupisa kwakanyanya uye hunyoro, senge cucumber, gourd inovava, melon uye zvichingodaro. Zvisinei, zvikanganiso zvacho hazvivanzi chokwadi. Kunyangwe kana mamiriro ari pamusoro akaitika, mhedzisiro yefirimu yezvekurima ichiri pachena kupfuura firimu rekurima. Nekuti chigadzirwa ichi chine mabhenefiti ari pachena mukubvisa mhute nekudonha, uye mutengo wakaderera, ungangoita 1.1-1.2 yuan pa square mita. Kuenzaniswa nemutengo weEVA firimu, mari yekuisa yakaderera, saka inofarirwa nevazhinji varimi vemiriwo. Iyo yazvino grouting firimu inosiyana mumhando yechigadzirwa nekuda kweakasiyana mazinga ekuzadza. Varimi vemiriwo vanofanira kuongorora zvakawanda pachigadzirwa chimwe nechimwe pavanenge vachitenga uye vosarudza kambani yepamutemo yekutenga.
4. EVA firimu.EVA greenhouse filmimhando yegreenhouse plastic film iyo parizvino inoshandiswa muhuwandu hukuru. Iyi mhando yefirimu ine super light transmittance, ine mwenje transmittance inopfuura 92%; ine yakanakisa kudonhedza anti-fogging zvivakwa, uye nguva yekudonha ndeye 4- Kupfuura 6 mwedzi; ine yakanakisa kuchengetedza kupisa, kuramba guruva uye super kuchembera kuramba (kupfuura 18 mwedzi). Three-layer EVA film inogona kushandiswa zvakanyanya kugadzira yakakwirira-yekupedzisira kusvibiswa kwehupfumi-isina miriwo, senge cucumber, tomato, mhiripiri, inovava gourd, etc. Iyo yakaipa ndeyokuti mutengo wakanyanya kukwirira. Zvinoenderana neakasiyana makuriro, mutengo wemusika uripo ndewekuti: 0.08 mm inowanzoita 2.05-2.1 yuan/square mita, uye 0.09 mm i2.15-2.2 yuan/square mita.
5. PO firimu zvakare rudzi rutsva rwefirimu rakagadzirwa mumakore achangopfuura. Iyi firimu yemhando yepamusoro-yekupedzisira inoshanda polyolefin yekurima firimu inogadzirwa kubva ku polyolefin. Iyo ine chiedza transmittance, inoenderera inopesana nefogging, inodonha uye inochengetedza kupisa. Etc., iri munzvimbo inotungamira pakati pemafirimu egreenhouse, ane mutengo wakakwira kuita, uye ndiyo inonyanya kuvimbisa mhando yefirimu. Ukobvu hwazvino hwepo firimu hunotangira pa8 filaments, 12 filaments, uye 15 filaments.
