假高粱是外来恶性杂草，在我国不断扩散和为害，必须对它进行防治。本文综述假高粱的研究成果，为它的防治提供指导。首先综述了假高粱的形态特征与同属其他种的区别，主要是秆粗0.5 cm，叶舌长1.0～1.5 cm，外颖顶端3齿裂。含假高粱的土壤中小麦、棉花、莴苣的种子发芽率被抑制40%以上；小麦、玉米、棉花地上部分生长被抑制9.8%以上。对假高粱的防治可以采用10%尿素和15%碳铵灭杀其种子；可以用白萝卜和昆虫抑制其生长；使用咪唑乙烟酸、甲氧咪草烟、草铵膦、烯草酮加草铵膦可以杀死94%的植株；喔草酯和喹禾灵可以减少假高粱的生长97%以上。可以利用假高粱喂养中华稻蝗，也可以用来造纸。提出了...

Sorghum halepense is a noxious exotic weed in China that has become widely spread,and it affects the growth of several crops.In this article,we review research on S .halepense and measures to control its spread.First,we summarize the main differences between S .halepense and other plants belonging to the same genus.The stalk diameter of S .halepense is 0.5 cm,the ligule length is 1.0 -1.5 cm,and the outer glume top has three slits.The presence of S .halepense in soil inhibits the germination and growth of other plants. For example,in soil containing S .halepense ,the seed germination rates of ...
