我省花生地膜覆盖栽培面积逐年扩大。然而地膜覆盖田由于环境条件的改变,使其杂草生态发生了变化。不但杂草出土高峰期来的早,长势凶猛,而且杂草又囿于膜下难以防除,因此覆膜花生田易形成草荒(呈“沙发状”)。针对这种情况,我们开展了除草地膜的研制工作。除草地膜简称药膜,系伴随地膜栽培技术而产生的一种农药加工新剂型(即以普通地膜为载体,经过特殊的工艺方法而制造的含有化学除草剂的复合膜)。经室内外生物测定表明;药膜不但具有显著的除草作用, Peanut film mulching cultivation area expanded year by year. However, the mulching field has changed its weed ecology due to the change of environmental conditions. Not only weeds come out early peak, fierce, and weeds are difficult to control in the film, it is easy to form a grassland covered with peanut waste (was “sofa-like”). In response to this situation, we carried out the development of weeding film. Herbicides Membrane referred to as the membrane, accompanied by the film cultivation techniques resulting from a new pesticide processing formulations (that is, the ordinary film as a carrier, through a special process of manufacturing chemical herbicide-containing composite membrane). The indoor and outdoor bioassay showed that the medicinal film not only has significant herbicidal effect,
