摘要
本文综述了有机改良剂的类型及其在防治作物土传病害的应用情况 ,包括壳质粗粉、植物残体、绿肥、饼肥、堆肥和粪肥 ;概括了有机改良剂的防病机制 ,如直接的抑菌作用、对土壤微生物区系的调节、诱导抗病性、改良土壤结构和促进植物生长等 ;讨论了当前有机改良剂防治作物土传病害研究存在的一些问题及今后应重点研究的课题 。
This article summarized the advances in control of plant soil borne diseases by organic amendments, recapitulated the kinds of the organic amendments, including chitin powder, plant residue, green manure, cake manure, compost and livestock manure; illuminated their acting mechanism, such as inhibiting pathogen germination and growth,changing the soil microflore and increasing the population of antibionts,inducing plant resistance,improving soil structure and promoting plant growth and so on; discussed the problems in application of organic amendments,and predicated their development in the future.
