可降解的控制农药释放材料(淀粉基)的研究

Studies on the degradable materials of controlled release agrochemicals (starch foundation)

主要研究以淀粉为基材的降解材料的配方及其缓释性质。实验基本配方为淀粉、溶剂和交联剂混合形咸紧密交联的产物，随交联物的降解，使包裹在其中的化肥逐步释放。实验主要研究溶剂和交联剂的用量、溶剂和交联剂应用时的加入顺序以及浸泡方式对缓释的影响。

The controlled-release character and formulation of degradable materials with starch used as the base material were studied. The compact crosslinked product was prepared by using solved and crosslinker to modified starch. The pesticide can release gradually along with the above-mentioned product. The effect of the amount of solvent and crosslinker, the turn of blend, the pattem of soak on controlled -release were studied.
