| 甘肅省農資部門日前進行的一項調查顯示，隨著大棚經濟的迅速升溫，農民現在使用的普通農膜已經滿足不了當前的各類種植的需求。他們迫切需要新品農膜，以提高農業的綜合效益。
據(ju)了解，農(nong)(nong)(nong)民現在使(shi)用(yong)的(de)(de)普通農(nong)(nong)(nong)膜(mo)大(da)都抗寒性(xing)差、不(bu)(bu)(bu)耐(nai)老化，易脆易裂，壽命只有(you)一年左右，因此渴望能(neng)夠用(yong)上(shang)(shang)透光、保溫、保濕、抗寒、耐(nai)老化、多(duo)功(gong)能(neng)的(de)(de)新(xin)品(pin)(pin)農(nong)(nong)(nong)膜(mo)。由(you)于不(bu)(bu)(bu)同(tong)(tong)顏色(se)的(de)(de)農(nong)(nong)(nong)膜(mo)對光的(de)(de)吸收、折射(she)和反射(she)不(bu)(bu)(bu)同(tong)(tong)，因此對各類(lei)農(nong)(nong)(nong)作物的(de)(de)作用(yong)也不(bu)(bu)(bu)同(tong)(tong)。如覆(fu)蓋(gai)(gai)紅(hong)色(se)農(nong)(nong)(nong)膜(mo)的(de)(de)西紅(hong)柿(shi)和黃瓜較覆(fu)蓋(gai)(gai)白色(se)農(nong)(nong)(nong)膜(mo)的(de)(de)能(neng)提前30至45天上(shang)(shang)市(shi)，所以農(nong)(nong)(nong)民盼望廠家生(sheng)產多(duo)種有(you)色(se)農(nong)(nong)(nong)膜(mo)，以適(shi)應不(bu)(bu)(bu)同(tong)(tong)作物的(de)(de)種植(zhi)需(xu)(xu)要。此外，由(you)于廢舊農(nong)(nong)(nong)膜(mo)不(bu)(bu)(bu)能(neng)或不(bu)(bu)(bu)易降(jiang)解，在農(nong)(nong)(nong)村造(zao)成了'白色(se)污染'，成為一大(da)公害，因此可降(jiang)解的(de)(de)新(xin)品(pin)(pin)農(nong)(nong)(nong)膜(mo)更(geng)易被農(nong)(nong)(nong)民接受。目前市(shi)場(chang)上(shang)(shang)的(de)(de)農(nong)(nong)(nong)膜(mo)大(da)多(duo)是(shi)功(gong)能(neng)單一的(de)(de)長(chang)條(tiao)型，給(gei)不(bu)(bu)(bu)同(tong)(tong)需(xu)(xu)求的(de)(de)使(shi)用(yong)者帶來了不(bu)(bu)(bu)便。如能(neng)生(sheng)產出大(da)塊(kuai)型、塊(kuai)型、圓(yuan)型等(deng)多(duo)種規格的(de)(de)新(xin)品(pin)(pin)農(nong)(nong)(nong)膜(mo)，將給(gei)農(nong)(nong)(nong)民提供更(geng)多(duo)的(de)(de)選擇。 |
