中文摘要：
壳聚糖具有成膜性、抗菌性及无毒无害等多种优良性能，以壳聚糖（CTS）为主要在膜材料，并辅以月桂酸钠改性的纳米TiO2，制备了一种新型安全无毒的涂膜剂壳聚糖／纳米TiO2复合涂膜，与农药（P）原药混合后，制得壳聚糖-纳米TiO2-农药复合膜剂型（CTS—TiO2-P）。分别用配置好的P（对照），壳聚糖-农药（CTS—P）及CTS—TiO2-P溶液喷施农作物，用GC—FPD）（气相色谱-火焰光度检测器）对3种溶液喷施后在植株上的农药残留量动态情况进行检测和比较，试验结果表明：当溶液中农药的质量分数为0．04％，复合膜溶液中壳聚糖的质量分数为2％，纳米TiO2质量分数为0．03％时，复合膜剂型农药在植株上的长效性比单纯农药的长效性明显提高，而且添加了纳米TiO2的复合膜农药效果优于单纯的壳聚糖-农药复合膜，药效持续时间由45天延长到90天以上，这样可以减少农药的施药次数；同时，在达到相同的杀虫效果的条件下，可以节约1／2的农药用量，这对减少农药资源的浪费、降低生产成本及防治环境污染具有较好的作用。
英文摘要：
Chitosan has many excellent properties such as film - forming, non - toxic, antibacterial, choosing chitosan as the main film -forming material, supplemented nano -TiO2 modified by Sodium Laurate, prepared a new type of safe, non - toxic film called CTS - TiO2 composite film, then mixed with Pesticide（P） prepared a composite film called CTS- TiO2 -P,the crops were sprayed by the prepared solution P（ contrast）, CTS - P and CTS - TiO2 - P separately, the dynamic test results of CTS - TiO2 - P, CTS -P,P on plant were detected and compared by GC -FPD. The results showed that when the ratio of P,chitosan and TiO2 was 0.04% ,2% ,0.03% separately,the long- term effects of pesticide compound membrane were significantly longer than that of the pure pesticide, composite membrane pesticide formulations added nano - TiO2 were superior to CTS - P composite membrane, the efficacy of composite membrane pesticide formulations extended from 45 d to CTS -P composite membrane, the efficacy of composite membrane pesticide formulations extended from 45 d to 90 d and above. Meanwhile , at the condition of reaching the same effect of killing inserts, pesticide usage can be saved 1/2, it has better effect to reduce the waste of peaticide resources, production costs and to prevent and control environmental pollution.
