        農膜行業市場暗含著巨大的發展潛力

        文章出處:   責任編輯:   發布時間:2016-06-20 08:54:00    點擊數:-   【

        農膜行業快速發展對提高土地產出率、增強農業抗災能力、實現農業穩產高產、促進種植業結構優化、增強農產品有效供給、提高農民收入做出了巨大貢獻,這對于我國可耕地少、自然條件差的狀況有著更加重要的意義。

        近年來,隨著新型城鎮化和農業現代化步伐的加快,農膜發展空間越來越大。而隨著“生態高質農業”(就是充分應用現代及未來新能源、新材料、新裝備以及新信 息、新生物技術等武裝起來的農業高新技術體系及生產模式)的新目標提出,這對農膜也提出了更新更高要求,這也是一個重大發展機遇。

        現代農業對農膜提出新要求

        目前我國農膜產品門類齊全,是世界上薄型化農膜生產水平最高的國家。具有長壽、流滴、保溫、消霧、防菌、轉光、高透光等功能的各種單層、多層復合棚膜,流 滴、除草、增溫、降解、防蟲等功能的地膜,日光溫室、蔬菜、瓜果、花卉、煙草、棉花、青貯等專用農膜已得到廣泛應用,其中不乏具有中國特色、適合國情且具 有國際競爭力的創新產品,產品的質量、技術水平有的已達到國際先進。農膜產品結構得到一定優化,功能性農膜產品已占農膜總量約50%。

        但在看到行業成績、優勢和光明前景的同時,也應清醒地認識到產業存在的問題與不足。一是總體技術、管理水平與發達國家相比還有較大距離;二是生產集中度低,產能過剩,中高檔、功能性農膜比例偏低,從而引發無序競爭,市場混亂;三是品種、質量、功能還不能完全滿足現代化農業栽培技術和國家的優質高效、環保和資源節約的要求。

        發展農膜要注意兩個問題

        地膜向實現農業的環境保護和清潔生產方向努力,要繼續加大功能膜的開發和新材料開發應用。

        一方面,發展、普及長壽、流滴除草、增溫、防蟲等功能性地膜,保證春覆和秋覆膜使用仍能回收。甘肅部分企業生產的使用時間長達18個月的耐老化、銀黑等可回收地膜,就很受歡迎,河南銀豐塑料有限公司銀黑雙色生物降解地膜開發應用也取得較好成績并獲得塑協優秀成果獎。

        另一方面,加快新型樹脂如改性pet耐老化地膜開發研制與應用。特別要加快完全生物降解地膜農田實驗進度。

        技術要有新突破為推動塑料加工業技術進步和科技創新,中塑協曾明確了塑料加工業“功能化、輕量化、微成型”發展趨勢和方向。目 前農膜行業發展中急待解決的八個方面問題,如可降解塑料聚乳酸改性;高透明功能與壽命同步薄膜及高性能節水器材產業化;長效光生態、光轉換農膜生產技術; 生物基塑料加工及裝備關鍵技術;廢舊地膜回收與高值化利用;長效流滴消霧農用功能棚膜及聚合物基納米復合涂液推廣;農用功能性覆蓋材料的功效延長技術及應 用;農膜增薄涂層涂布裝置技術研究等。

        要把解決農膜表面自潔,使其保持較長時間透光率作為一項重要任務。特別是功能與壽命同步薄膜開發成功后,由于自然環境影響,這種長壽功能膜更需解決表面 自潔。因此加快新型樹脂、納米級、保溫劑、抗靜電劑的研究開發,同時加強對薄膜表面進行自潔處理,需在技術可行和低成本之間進行艱難選擇。

        要加快光譜匹配程度高、熒光衰減與農膜壽命同步的轉光劑的開發,為轉光大棚膜、轉光保溫地膜、轉光反光地膜等專用功能膜生產和發揮農膜肥、藥效能提供可靠保證,同時有條件的科研單位與企業要抓緊對各種特色果蔬生產特點進行研究,剖析各自所需光的不同波段,逐步建立起這方面資料庫,為開發特色果蔬使用專用膜創造條件。

        要加強高端棚膜的研發力度,加大在線涂覆po膜、多功能復合膜的推廣應用。高端農膜市場前景廣闊,是農膜行業高端化戰略的重要領域,也是未來農膜一個重要發展方向。

        要加強功能涂覆液的研究和推廣,加快農膜超薄涂層涂布設備生產,加快高效、節能、智能化多層供給設備的國產化,為農膜行業提供裝備技術支撐。
