摘　　要：通过在广东省花生主产区进行花生除草地膜覆盖栽培试验,探讨了该地膜对不同土壤类型和不同耕作制度的花生田间杂草的防除效果。结果表明:花生除草地膜适用于广东省各花生主产区,且产量平均增加28.93%;花生除草地膜对水旱轮作田和旱地的杂草防除效果略有不同,其中对水旱轮作田杂草的防除效果达80%以上,对旱地杂草的防除效果高达90%以上且防效稳定;在前茬作物为水稻或蔬菜的花生地,花生除草地膜对田间的防除效果均达到80%以上,但要注意控制多年生杂草。The experiments of herbicidal plastic film（HPF）mulching in peanut fields were invested in key peanut growing regions of Guangdong Province, in order to discuss the influence of difference soll characteristics and cropping system for herbicide effects. The results showed that HPF all fit to key peanut growing regions ,and the average yield of peanut covered HPF increased 28.93%; The eradication rate was different between rice crop rotation fields and dry cropping lands. The rate of PHPF used in rice-peanut crop rotation fields was more than 80%. The rate up to 90% in the dry cropping lands, which was high and stead. And the rate used in these fields, which foreerop were flee or vegetable, all was more than 80%, but the perennial weeds must been prevented and controlled before mulching PHPF in these fields.
