易降解淀粉膜的研制

Development of Degradable Starch Film

易降解淀粉膜，是采用一种具有良好疏水性能和高分散度以及优良自由流动性且价廉易得的新型专用淀粉，经与助剂配合吹塑制得的具有光-生物双降解特点的淀粉膜产品。该膜的力学性能达到或基本达到了普通地膜的标准。大田应用效果表明，易降解淀粉膜在山西省干旱、半干旱区主要农作物上覆盖，可获得与普通地膜一致的增产效果。

Degradable starch film is a kind of film products which has bio- photo two- waydegradable property. It is made by blowing molding from a new type special starch, which combining with flux. It has the advantages of higher disperse, better water-risistance and nuidity.Its mechanics performances mainly reach the standards of the same type products. The effects infarm using made it clear that covering degradable starch film may gain the same rate of growthwith general one on the main crops in arid and semiarid areas in Shanxi province.
