摘要：针对药效、药害、残留等农药焦点问题,探讨低碳条件下草甘膦、喹啉酸等与腐植酸活性组分作用,形成生物活性肽、多糖衍生物转化为植物营养,促进三羧酸循环的机理;探讨新烟碱、拟除虫菊酯等在水解酶、氧化还原酶、聚合酶及辅酶作用下,脱硫、脱氰、脱氮再转化为特异性维生素、蛋白质类植物营养的自由基反应历程;对保障粮食、蔬果丰收,构建可持续发展的和谐社会有深远意义。
Considering the focus of pharmacology, phytotoxicity and pesticide residues, this paper elaborated the convertion of glyphosate, quinolinic acid and humic acid active component to plant nutrition by forming bioactive peptides, polysaccharides and its derivatives, as well as the mechanism of promoting tricarboxylic acidradical reactions under the low-carbon condition. Moreover, this paper also described the process of radical reaction through which the new nico- tine and pyrethroid converted to plant nutrion such as specific vitamin, protein by desulfurization, decyanation, denitrification with the help of hydrolase, oxide reductase, polymerase, and coenzyme. So it is significant to ensure the food security, fruits and vegetable harvest as well as sustainable development of harmonious society.
