目前,在世界各地大约分布有3万种杂草,其中约1800种每年会带来约9.7%的总产量损失[1]。而化学除草剂大量使用,造成了一系列的环境问题,如抗药杂草种群的增加、土壤板结、水体污染等,严重影响了和谐可持续的农业发展。随着生物,化学等相关学科的发展,以及环境意识的提高,出现了 At present, there are about 30,000 weed species distributed around the world, of which about 1,800 species each year will bring about 9.7% of the total yield loss [1]. The heavy use of chemical herbicides has caused a series of environmental problems, such as the increase of resistant weed populations, soil compaction, water pollution, etc., seriously affecting the harmonious and sustainable agricultural development. With the development of biology, chemistry and other related disciplines, as well as the improvement of environmental awareness, there emerged
