1990年7月25日,在饶河县永乐乡关门村麦田中发现了一种毒麦,经南京农业大学李扬汉教授鉴定,为黑麦草属欧毒麦Lolium persicum Boiss.& Honen。欧毒麦以种子繁殖,在土内10cm深处尚能出土,在室内放至两年,仍具萌发能力。分蘖力较强,一般有3～6个分蘖;适应性较强,不论旱涝年,繁殖能力均比小麦高出1～2倍。出苗期比小麦晚,但出土后生长迅速,抽穗和成熟都早于小麦,而且容易脱落,在麦收时,落粒率为10％左右。对欧毒麦的防治方法,可采用50％硫酸铵或60％硝酸铵浸泡麦种,将漂浮水
On July 25, 1990, a poisonous wheat was found in the wheat field of Guanmen Village, Yongle Township, Raohe County. It was identified by Professor Li Yanghan of Nanjing Agricultural University as Lolium persicum Boiss. & Honen. European poison wheat to seed breeding, can still unearthed in the depths of 10cm in the soil, to two years in the room, still germination ability. Tillering strong, generally 3 to 6 tillers; strong adaptability, regardless of drought and flood years, reproductive capacity than wheat 1 to 2 times higher. The emergence period was later than that of wheat, but the growth was rapid after excavated. The heading and maturity were earlier than that of wheat, and it was easy to fall off. When the wheat was harvested, the rate of falling was about 10%. On the prevention and treatment of poisonous wheat in Europe, 50% ammonium sulfate or 60% ammonium nitrate can be used to soak wheat seeds, floating water
