有机生态型无土栽培基质重复利用研究概述

Review of the research on reuse of organic ecotype soilless culture substrates

目前有机生态型无土栽培在我国应用广泛,提高栽培基质的重复利用效率、减少消耗,并对废弃的基质加以循环利用,是现阶段无土栽培中需要重点解决的问题,对降低成本、保护环境、实现资源可持续利用具有重要意义。从养分管理、理化性状、微生态环境及自毒作用等四个方面重点分析了有机基质重复利用中的技术障碍及相应的修复措施,并对废弃基质再利用的价值和必要性及循环利用方式和效果等进行了阐述;指出了目前有机基质栽培中亟待解决的问题及未来的发展趋势,旨在为有机基质高效重复利用提供借鉴。

Currently,organic ecotype soilless cultivation is widely used in China.It is important to improve the reuse efficiency of cultivation substrate,reduce consumption and recycle waste substrate,which is of great significance for reducing costs,protecting the environment and realizing sustainable development of resources.In this paper,the technical obstacles and repair measures about the reuse of organic substrates were analyzed from four aspects:nutrient management,physical and chemical properties,microbial environment and autotoxicity.The value and necessity of reuse of matrix waste,the way and effect of recycling are expounded.The problems to be solved urgently in the cultivation of organic substrates and the future development trend were also pointed out,aiming at providing reference for the efficient recycling of organic substrates.
