【摘要】 农业资源高效利用是实现我国农业可持续发展的重大需求。利用纳米化学方法可实现肥料和农药等农业资源的高效利用,使农作物产量显著提高。但随着纳米材料用量的不断增大,人们又开始担心纳米材料的安全性,担心纳米材料应用后是否会影响农业生态,是否会蓄积于供食用的农产品中从而危害人类的健康。因此,开展纳米化学和纳米技术在农业领域的理论和应用研究对实现我国农业生产高效、安全、可持续发展具有显著的紧迫性和必要性。本文将报告我们在合成高分子纳米载体和表面活性剂及其在农业领域肥料和农药等高效利用上的初步应用结果。主要内容包括:(1)用于肥料和农药控释的功能性纳米粒子的合成和表征;(2)纳米沉淀法制备纳米肥料和纳米农药;(3)纳米材料的农作物生物学效应,安全评价和增效机理初探。更多还原

【Abstract】 High efficient utilization of agricultural resources is the major requirements to achieve the sustainable development of agriculture in china.Fertilizers,pesticides and other agricultural resources can be utilized efficiently and the crop yield can be improved by employment of nano-chemistry methods.It is also urgent and necessary to achieve significant safety and sustainable development of agriculture.In this paper,we will report the synthesis of surfactants and polymer nanoparticles as well as their preliminary applications in the efficient utilization of fertilizers and pesticides in agriculture.The main contents include:(1) Synthesis and characterization of functional nanoparticles for controlled release of fertilizers and pesticides;(2) Preparation of nano-sized particles of fertilizers and pesticides by nano-precipitation methods;(3) Crop biological effect,safety assessment,and crop yield increasing mechanism of nano-materials.更多还原
