鉴定了７种型号可控光——生物降解淀粉塑料薄膜（双降解农膜）在兴安盟的适应性以及对玉米生育、产量的影响，１９９７、１９９８年２年试验结果表明：该农膜能降解成网状碎片，基本不影响后作，具有降低土壤污染的优点；增温保墒、促进玉米生长发育和提早成熟，增产效果优于普通膜；诱导期６０～７０ｄ的膜较适合我盟的气候特点。
The adaptability of 7 types of controllable photo-biodegradable starch plastic film (double degradable agricultural film) in Xing’an League and their effects on the growth and yield of maize were identified. The results of two years in 1997 and 1998 showed that the plasticity Degradation into a network of fragments, the basic does not affect the after work, with the advantages of reducing soil pollution; warming soil moisture, promote corn growth and early maturity, the yield is better than ordinary film; induction 60 ~ 70d film is more suitable for the Union Climate characteristics.
