豚草(Ambrosia artemisiifolia L.)和三裂叶豚草(Ambrosia trifida L.)俗称艾叶破布草和破布草,是影响人类健康和作物生长的危险性杂草。这两种杂草在20世纪40～50年代传到我国,在长江流域零星分布,现在已分布在我国大部分地区。从普查情况看,豚草和三裂叶豚草在黑龙江省有扩散蔓延的趋势,对农田已形成包围态势,这将对本省农业生产构成极大的潜在威胁。因此,必须大力宣传,提高认识,加大力度,在短时间内把豚草防除、歼灭。
Ambrosia artemisiifolia L. and Ambrosia trifida L., commonly known as Artemisia annua and Ragweed, are dangerous weeds that affect human health and crop growth. These two kinds of weeds spread to our country from the 40s to the 50s of the 20th century and sporadically distributed in the Yangtze River valley and are now distributed in most areas of our country. From the census situation, ragweed and Crataegus triphylla in Heilongjiang Province, there is a proliferation of the trend of encroachment on the farmland has formed, which will pose a huge potential threat to the province’s agricultural production. Therefore, we must vigorously publicize, raise awareness and intensify our efforts to prevent and eliminate ragweed in a short period of time.
