摘　　要：本研究通过对聚乙烯防虫网进行纳米TiO_(2)改性,分析了改性前后防虫网的力学性能、抗菌性能、透光性和透气性,并通过田间试验验证其在园林病虫害防治中的效果。结果显示,纳米TiO_(2)改性显著提升了聚乙烯防虫网的综合性能,使其在园林病虫害防治中的应用效果更加显著。改性防虫网的拉伸强度从25.3MPa增加到28.7MPa,撕裂强度从15.6N增加到18.2N;对大肠杆菌和金黄色葡萄球菌的抑菌率分别达到85.2%和82.6%。田间试验表明,改性防虫网显著减少了害虫数量,并改善了植物健康状况。研究结果可为防虫网的进一步优化和大规模应用提供科学依据,有助于推动绿色环保防虫技术的发展,减少化学农药的使用,保护生态环境。This study investigates the modification of polyethylene insect nets with nano-titanium dioxide(TiO_(2))and analyzes the mechanical properties,antibacterial performance,light transmittance,and air permeability before and after modification.Field trials were conducted to evaluate their effectiveness in garden pest control.The results show that TiO_(2) modification significantly enhances the overall performance of polyethylene insect nets,improving their effectiveness in garden pest control.The tensile strength of the modified inset nets increased from 25.3MPa to 28.7MPa,and the tear strength from 15.6N to 18.2N.The antibacterial rates against E.coli and S.aureus reached 85.2%and 82.6%,respectively.Field trials indicated that the modified nets significantly reduced pest numbers and improved plant health.These findings provide a scientific basis for further optimization and large-scale application of insect nets,promoting environmentally friendly pest control technologies,reducing the use of chemical pesticides,and protecting the environment.
