Chomera chopumira choyera chopanda nsalu chamunda chimakwirira nsalu yoteteza kuchisanu

Pamene nsalu zaulimi zopanda nsalu zokhala ndi zofunikira zosagwira ntchito zimagwiritsidwa ntchito popanga ulimi, sikuti zimangolephera kupereka chitetezo chabwino komanso kusunga chinyezi, komanso zimakhudza kukula kwa mbeu. Choncho, posankha nsalu zopanda nsalu zaulimi, ndikofunika kuonetsetsa kuti zikugwirizana ndi zofunikira za ntchito.

Insulation: Chifukwa nsalu zosalukidwa zimakhala ndi mpweya wochepa wopita ku kuwala kwautali kusiyana ndi mafilimu apulasitiki, ndipo kutentha kwa kutentha m'dera lausiku kumadalira kwambiri cheza cha longwave, pamene chikugwiritsidwa ntchito ngati chinsalu chachiwiri kapena chachitatu, chikhoza kuonjezera kutentha kwa greenhouses, greenhouses, ndi nthaka, zomwe zimapangitsa kuti pakhale kuchuluka kwa kupanga ndi ndalama. Kutentha kwapamtunda kumawonjezeka ndi pafupifupi 2 ℃ masiku adzuwa ndi kuzungulira 1 ℃ pa mitambo, makamaka pa kutentha kochepa usiku, zomwe zimachepetsa kwambiri kutentha kwapansi komanso kumapereka chitetezo chabwino, kufika pa 2.6 ℃. Komabe, kutentha kwa dzuwa pamasiku a mitambo ndi theka chabe la mausiku adzuwa.

Moisturizing: Nsalu zosalukidwa zimakhala ndi ma pores akuluakulu komanso ambiri, ndizofewa, ndipo mipata ya ulusi imatha kuyamwa madzi, zomwe zingachepetse chinyezi cha mlengalenga ndi 5% mpaka 10%, kuteteza kusungunuka, komanso kuchepetsa kupezeka kwa matenda. Malinga ndi mayeso oyenerera, chinyezi cha nthaka chomwe chimayezedwa pambuyo pophimba chikapezeka kuti chili ndi zinthu zabwino kwambiri zonyowetsa ndi magalamu 25 a nsalu zazifupi zopanda nsalu pa mita imodzi ndi 40 magalamu a nsalu ya spunbond yopanda nsalu pa mita lalikulu, motero, ikuwonjezeka ndi 51.1% ndi 31% poyerekeza ndi nthaka yosaphimbidwa.

Translucency: Ili ndi mlingo wina woonekera. Nsalu yosakhala yopyapyala imakhala yopyapyala bwino, imawonekera bwino, pomwe ikukula, imawonekera kwambiri. Kutumiza kwabwino kwambiri kumatheka pa 20 magalamu ndi 30 magalamu pa lalikulu mita, kufika 87% ndi 79% motero, ofanana ndi transmittance magalasi ndi polyethylene mafilimu ulimi. Ngakhale ndi 40g pa mita lalikulu kapena 25g pa lalikulu mita (yachidule CHIKWANGWANI otentha adagulung'undisa sanali nsalu nsalu), transmittance akhoza kufika 72% ndi 73% motero, amene angakwaniritse kuwala zofunika kuphimba mbewu.

Chopumira: Nsalu yosalukidwa imapangidwa ndi kuyika ulusi wautali mu mesh, yokhala ndi porosity kwambiri komanso mpweya wabwino. Kukula kwa mpweya permeability zikugwirizana ndi kusiyana kukula kwa nsalu sanali nsalu, kutentha kusiyana mkati ndi kunja kwa wosanjikiza chophimba, mphepo liwiro, etc. Nthawi zambiri, mpweya permeability wa ulusi lalifupi ndi kangapo kuti 10 apamwamba kuposa ulusi wautali; Kuthekera kwa mpweya kwa magalamu 20 pa mita imodzi kutalika kwa ulusi wosalukidwa wosalukidwa pamalo odekha ndi 5.5-7.5 kiyubiki mita pa lalikulu mita pa ola.

Shading ndi kuziziritsa: Kuphimba ndi nsalu zamitundu yopanda nsalu kungapereke mthunzi ndi zotsatira zoziziritsa. Nsalu zamitundu yosiyanasiyana zopanda nsalu zimakhala ndi shading ndi kuzizira kosiyanasiyana. Nsalu yakuda yopanda nsalu imakhala ndi shading yabwino kuposa yachikasu, ndipo yachikasu ndi yabwino kuposa buluu.

Zoletsa kukalamba: Nsalu zaulimi zosalukidwa nthawi zambiri zimathandizidwa ndi mankhwala oletsa kukalamba, ndipo nsaluyo ikakula, mphamvu zake zimachepa.
