Porous material carrier and application thereof in agriculture and forestry

Abstract

The invention provides a porous material carrier and application thereof in agriculture and forestry. The porous material carrier provided by the invention has a hollow or porous structure, is internally provided with a space, can load a solid or liquid target substance, and is released in a liquid or gas form. The target substance is released from pores of the carrier, the outflow speed or the volatilization speed of the target substance can be reduced, the slow release effect is achieved, and meanwhile the conveying time of the target substance can be prolonged. The porous material carrier is loaded with a target substance through a physical method, and is simple, convenient and easy to implement, high in loading capacity and high in loading efficiency. Moreover, the porous material carrier can be loaded for multiple times and can be repeatedly used, so that the cost is greatly reduced. The porous material carrier provided by the embodiment of the invention can be widely applied to providing nutrients for plants, preventing and treating plant diseases and insect pests, killing insects and carrying drug treatment on trees and crops, and has potential huge advantages in agriculture and forestry applications such as sustainable pest control and crop growth. 本发明提供了一种孔隙材料载体及其在农林业中的应用。本发明提供的孔隙材料载体，具有中空或多孔的结构，其内部具有空间，可负载固态或液态的目标物质，并以液体或气体的形式释放。所述目标物质从载体的孔隙中释出，可减慢其流出速度或挥发速度，达至缓释作用，同时还可加长目标物质的输送时间。所述孔隙材料载体通过物理方法载入目标物质，简便易行，且负载能力强，加载效率高。不仅如此，所述孔隙材料载体还可多次加载，重复使用，大大降低了成本。本发明实施例提供的孔隙材料载体可以广泛应用于给植物提供养分、防治病虫害、杀虫以及树木和农作物的载入药物治疗，在可持续害虫防治和作物生长等农林业应用中具有潜在的巨大优势。
