麦田草害是影响小麦产量和品质的重要因素之一。杂草生长力强,争夺水肥能力是小麦的2～7倍,直接影响小麦生长,对产量影响极大,一般造成减产10%～30%,甚至更高[1],特别是由于草害的发生,使其千粒重降低,严重影响小麦的品质。因此,科学安全地控制麦田草害的发生对小麦的优质高产十分重要。 Wheat field grass damage is one of the important factors affecting wheat yield and quality. Weeds grow strong, competing for water and fertilizer capacity is 2 to 7 times that of wheat, a direct impact on wheat growth, a great impact on the yield, generally resulting in 10% to 30% reduction or even higher [1], especially because of grass damage Occurred to reduce its 1000-grain weight, seriously affecting the quality of wheat. Therefore, it is very important to control the occurrence of wheat field scientifically and safely on the high yield and high yield of wheat.
