從中國科學院獲悉，近期，中科院合肥物質科學研究院技術生物與農業工程研究所研究員吳正巖課題組研制出光敏型控釋農藥，該技術為(wei)實現農(nong)(nong)藥按(an)需供(gong)給、減施增效(xiao)提供(gong)有(you)效(xiao)技術支撐(cheng)，有(you)利于促進農(nong)(nong)藥行(xing)業(ye)轉型升級和生態(tai)農(nong)(nong)業(ye)建設。
農藥(yao)對維持農業(ye)穩定(ding)高產(chan)發揮了重(zhong)要(yao)(yao)作(zuo)用，然(ran)而傳統農藥(yao)難以(yi)實現(xian)按(an)需給藥(yao)，導致利用率低，且(qie)引發嚴重(zhong)的環境污染，成為制約我國(guo)現(xian)代農業(ye)可持續發展的關鍵(jian)瓶頸問題，迫(po)切需要(yao)(yao)通過科技(ji)創新(xin)研(yan)發農藥(yao)控(kong)釋技(ji)術(shu)。
課(ke)題(ti)組(zu)利用納米(mi)黏土、光(guang)(guang)敏材(cai)料等制(zhi)備出一種復合納米(mi)材(cai)料，以該材(cai)料為載(zai)(zai)體(ti)與農(nong)(nong)(nong)(nong)藥復配研制(zhi)出光(guang)(guang)敏型控釋(shi)農(nong)(nong)(nong)(nong)藥。該農(nong)(nong)(nong)(nong)藥對紫外(wai)-可見光(guang)(guang)(365-435nm)具有較高(gao)的(de)敏感性(xing)，可通過光(guang)(guang)高(gao)效調控農(nong)(nong)(nong)(nong)藥釋(shi)放，實現農(nong)(nong)(nong)(nong)藥按(an)需供(gong)給，顯著提高(gao)利用率。同(tong)時(shi)，該載(zai)(zai)體(ti)可有效增強農(nong)(nong)(nong)(nong)藥附著力，延長藥效，且具有較強的(de)穩定性(xing)。該技術成(cheng)本(ben)低(di)、效率高(gao)、環境友好，應用前景廣闊。
