摘要
土壤熏蒸是目前防治土传病、虫、草害有效且快速的方法,但随着作物的种植,一些病原物可能会再次繁殖,导致病害持续发展,并且土壤经熏蒸处理后,会导致土壤微环境处于一种失衡状态,而土壤改良剂可以有效改善土壤环境、减少作物根部疾病、减少土壤养分流失并可提高农产品的品质。将熏蒸剂与改良剂联合使用在一定程度上可以修复或改良土壤,使受熏蒸剂影响的微生物群落得到恢复或有益微生物的相对丰度增加,防止土壤病原菌再次侵染,更有利于作物的生长。本文简单概述了常用熏蒸剂和土壤改良剂的分类信息,重点综述了土壤改良剂与熏蒸剂联合使用,对熏蒸后土壤的理化性质、酶活性、微生物群落及作物生长方面的影响,可为土传病害的防治、熏蒸剂与土壤改良剂的联合使用及相关机制研究提供参考。
Soil fumigation is currently an effective and rapid method to prevent soil-borne diseases,insects,and weeds.However,some pathogens may reproduce again as crops are planted,leading to the continuous development of diseases.After soil fumigation treatment,it will cause the soil microenvironment to be in a state of imbalance.Soil amendments can improve the soil environment,reduce crop root diseases,reduce nutrient loss and improve the quality of agricultural products.Soil fumigation combined with amendments can repair or improve the soil to a certain extent,restore the microbial community affected by the fumigants or increase the relative abundance of beneficial microorganisms,prevent soil pathogenic bacteria from reinfecting,which will make the soil more conducive to the growth of crops.This article briefly summarizes the classification information of commonly used fumigants and soil amendments,focusing on the combined use of soil amendments and fumigants to affect the physical and chemical properties,enzyme activities,microbial communities and crop growth of the soil after fumigation.Therefore,this study has provided the reference for the prevention and control of disease-borne diseases,the combined use of fumigants and soil amendments,and related mechanisms.
