近年来,糯玉米、甜玉米和笋用玉米等菜用玉米种植发展较快,种植方式有春玉米、夏玉米和地膜玉米,玉米苗期受杂草危害严重,苗期受杂草危害时,植株矮小,秆细叶黄,导致中后期生长不良,双穗率降低,空秆率提高,穗粒数和粒重明显下降,造成严重减产。玉米除草剂品种繁多,使用技术要求高,使用不当不但起不到除草效果,还会对玉米产生药害。 In recent years, waxy corn, sweet corn and bamboo shoots with corn and other vegetable maize planting developed rapidly, planting methods are spring corn, summer corn and plastic film corn, maize seedling severely affected by weeds, seedling damage by weeds, Plant short, yellow leaf stalk, leading to poor growth in the late, double ear reduction rate, increased empty stalk rate, grain number and grain weight decreased significantly, resulting in serious yield reduction. Corn variety of herbicides, the use of high technical requirements, improper use not only failed to weeding effect, but also produce phytotoxicity on corn.
