摘要:

單一種植(連作和簡(jiǎn)單輪作)和水肥高投入是我國(guó)設(shè)施蔬菜種植中的普遍現(xiàn)象,,這使得設(shè)施菜田土壤極易出現(xiàn)微生物多樣性下降、病原菌增多和寄生線蟲(chóng)為害等土壤微生物學(xué)障礙問(wèn)題。土壤微生物學(xué)障礙已對(duì)我國(guó)設(shè)施蔬菜種植體系土壤的可持續(xù)利用構(gòu)成了很大的威脅。土壤微生物是影響植物生長(zhǎng)、進(jìn)化進(jìn)程和生產(chǎn)力的重要因素之一。目前我國(guó)有關(guān)設(shè)施菜田土壤微生物學(xué)障礙的研究已取得了顯著的進(jìn)展。但是,多數(shù)研究側(cè)重于人為管理對(duì)土壤微生物學(xué)因子影響的一般性變化的了解,缺乏對(duì)土壤生態(tài)服務(wù)功能變化的深入研究。為此,本文闡述了國(guó)內(nèi)外土壤微生物學(xué)障礙研究,并在此基礎(chǔ)上概述了土壤微生物-作物互作的生態(tài)學(xué)效應(yīng),分析了設(shè)施菜田土壤微生物學(xué)障礙研究的關(guān)鍵點(diǎn)。此外,本文簡(jiǎn)要介紹了目前我國(guó)設(shè)施菜田土壤微生物學(xué)障礙調(diào)控的主要生態(tài)措施,并對(duì)未來(lái)深入揭示設(shè)施菜田土壤微生物學(xué)障礙的潛在成因的關(guān)鍵切入點(diǎn)提出了建議。

Abstract:

Simple cropping(including continuous cropping and simple rotation)and excessive water and fertilizer input are 2 common phenomenon in Chinese protected vegetable cultivation.This phenomenon results in the problems of soil biological obstacles:as reduction of microbial diversity of protected vegetable soil,increasing of microbial pathogens, and damage of plant-parasitic nematodes, etc.Soil microbial obstacles have greatly threatened the sustainable utilization of soils in protected vegetable production systems in China.Soil microbe is one of the important factors that influence the plant growth,evolutionary process and productivity.Currently studies on vegetable soil microbial obstacles in protected cropping system have made significant progress.However,most of the study efforts are mainly focused on the general changes of soil microbial communities responding to human management,and thorough studies on change of soil ecological service function are needed to carry out. Therefore,this paper reviewed the internal and external studies on soil microbial obstacles, summarized the ecological effect of soil microbe-crop interaction and analyzed the key point for studying vegetable soil microbial obstacles in protected cropping systems.Besides,this paper briefly introduced the major ecological measures adopted in China to control these obstacles.It also provided suggestions for revealing potential causes of these obstacles in the future.
