微生物肥料在玉米上的应用研究进展

Research Progress on the Microbial Fertilizer Application in Maize

从促生、生防、抗非生物胁迫的角度,总结微生物肥在玉米上应用的国内外研究进展,重点介绍不同类型微生物肥料对玉米生长、产量、子粒品质、抗病性、抗逆性及节肥潜力上的应用效果。研究表明,微生物肥料增加了玉米产量,增产幅度为1.3%~39.7%。利用微生物肥料可能减少15%~30%的化肥用量。建议针对土壤类型、气候条件以及不同玉米品种等,筛选高效的微生物肥料或菌株,优化微生物肥料生产设备工艺,并加强微生物生态适应性基础研究。

This article summarized the current status of the microbial fertilizer application in maize from the perspectives of growth-promoting,biological control and abiotic stress resistance,focusing on the application effects of different types of microbial fertilizers on maize growth,yield,grain quality,disease resistance,stress resistance and fertilizer saving potential.About 91%of the researches showed a positive effect of bio-fertilizer on maize yield,increasing maize yield by 1.3%to 39.7%.By application of bio-fertilizers,the amount of chemical fertilizer can be possible reduced by 15%-30%.It is suggested that,to facilitate the application of bio-fertilizer in maize,efficient microbial fertilizers and strains should be screened specifically adapted to soil types and climatic conditions,even different maize cultivars.The equipment and technologies to produce microbial fertilizers should be optimized.The basic research on microbial ecological adaptation of should be strengthened.
