主要研究以淀粉/PE为基材的农药缓释性能。具体讨论不同配比的淀粉/PE共混物对农药释放性能的影响;并通过SEM测试分析了淀粉与PE之间的相容性;研究了不同淀粉含量、不同温度以及不同pH值对多菌灵释放量的影响。实验结果表明:淀粉含量越高,缓释剂的释放速率越快;PE∶淀粉∶农药=0.296∶0.504∶0.2、温度40℃、pH=4时,共混体系的缓释效果最佳。 The main research to starch / PE as the base of the pesticide sustained release properties. The effects of starch / PE blends with different proportions on the release properties of pesticides were discussed in detail. The compatibility between starch and PE was analyzed by SEM. The effects of different starch contents, different temperatures and different pH values ​​on the release of multi-bacteria Effect of Spiritual Release. The experimental results showed that the higher the starch content, the faster the release rate of the sustained-release agent; the best slow-release rate of the blend system was obtained when the ratio of PE: starch: pesticide = 0.296: 0.504: 0.2, temperature: 40 ℃, pH = 4.
