微生物除草剂的研究进展

Research Status and Prospect of Microbial Herbicides

杂草对农业生产构成了巨大的威胁,对农业经济带来了深远的影响。过度依赖化学除草剂的现象引发了大量的抗药性杂草种群出现,这不仅增加了除草剂的使用频率和用量,还会引发恶性循环。通过对现有文献和研究数据的分析,阐述了微生物除草剂的分类及其对目标杂草物种的生物除草活性和特异性。微生物除草剂凭借其延缓杂草产生耐药性、对生态环境影响较小、安全性高和资源充足等独特优势,有望满足可持续农业发展的需求。本文进一步分析了国内外微生物除草剂的发展现状及面临的限制因素,并展望其未来的发展方向和利用趋势。

Weeds posed a great threat to agricultural production and had far-reaching consequences for the agricultural production.Overreliance on chemical herbicides had resulted in large populations of resistant weed population,which not only increased the frequency and dosage of herbicides,but also triggered a vicious cycle.By analyzing current literature and research,this paper outlined the classification of microbial herbicides,and described their bioherbicidal activity and specificity against target weed species.Microbial herbicides were expected to fulfill the needs of sustainable agriculture development due to their unique advantages such as delaying the development of resistance in weeds,less ecological impact,high safety and sufficient resources.This paper further analyzed the current development status of microbial herbicides at home and abroad and the constraints they were facing and anticipated their future development direction and utilization trends.
