摘　　要：玉米专用除草地膜是一种兼具除草及地膜其他功能的新产品。为了探明玉米专用除草地膜的田间使用效果,通过大田试验研究了其对杂草的防效以及对玉米的安全性。结果表明,玉米专用除草地膜可有效防治田间的马唐、牛筋草、胜红蓟等一年生杂草,覆膜后2个月对杂草的防效均在80%以上,同时覆盖玉米专用除草地膜可有效地提高玉米产量。使用玉米专用除草地膜较直接喷施除草剂药效期延长,且对玉米生长安全无不良影响。Herbicidal plastic film for corn was a new kind of product with weeding and film functions. Tostudy application effect of HPFC, the corn safety and control efficacy of weeds with HPFC was researched inthe field. The results showed that HPFC could effectively control annual grasses such as Digitaria sanguinalis,Eleusine indica, Ageratum conyzoides in the field, control efficiency more than 80% within two months aftermulching of HPFC, as yiehl was increased effectively. Using HPFC was safely for corn, and effective period ofherbicide was longer than that of spraying herbicide directly.
