今年麦收之前,在丹江口市右岸的部分麦田里发现了毒麦。毒麦是一种有毒的杂草。是国家规定的检疫对象。毒麦种子含有毒麦碱,具有麻醉作用。面粉中若含有4%的毒麦,人吃后就会引起中毒,甚至死亡,应引起高度重视。 毒麦和小麦很相似,但毒麦幼苗茎部呈紫红色,以后呈绿色。成株茎秆坚硬,在肥田里比小麦矮,在瘦田里比小麦高。穗形狭长,每穗有8—19个小穗,每小穗有2—6个籽粒,互生于穗轴上。籽粒呈长椭圆形,灰褐色,坚硬,无光泽。成熟后易脱落于田间。
Before the wheat harvest this year, poison wheat was found in some of the wheat fields on the right bank of Danjiangkou City. Poisonous wheat is a poisonous weed. Is the quarantine object of the state. Poisonous wheat seeds contain toxic aesthetics, with anesthetic effects. If the flour contains 4% of toxic wheat, people will cause poisoning or even death after eating, which should arouse great attention. Poisonous wheat and wheat are similar, but poisonous wheat stems are purple, later green.

Spikes narrow, each spike 8-19 spikelets, each spikelet 2-6 grains, alternate in the cob. The grain is oval, taupe, hard and dull. Easy to fall off in the field after ripening.
