在当今的中国,人多地少的资源不合理分配的现实条件下,再加上大量的杂草侵占农作物的生存空间导致农作物减产造成经济损失严重的情况下,如何提高农作物的产量成了科学家们的重要问题.伴随着生活水平的提高,人们越来越注重环境问题,在上个世纪大量的化学除草剂给环境造成了严重的后果,因此寻找残留少、无毒副作用、环境负效应小、不破坏生态环境、安全性高的除草剂成为当务之急.近来,具有除草活性的天然物质引起了科学家们的关注,
In today’s China, where more people are spending less and less resources irrationally allocated, and when a large amount of weeds encroach on the living space of crops, resulting in serious economic losses caused by reduced yields of crops, how to increase the output of crops has become a scientist With the improvement of living standards, people pay more and more attention to environmental problems. In the last century, a large number of chemical herbicides have caused serious environmental consequences. Therefore, they are searching for less residuals, no toxic and side effects, and small negative environmental effects , Do not undermine the ecological environment, high safety herbicides become a top priority.Recently, the natural substances with herbicidal activity attracted the attention of scientists,
