化学除草是推广花生覆盖地膜的重要环节。我们利用现有的、经济的两种除草剂-五氯酚钠、除草醚,在地膜花生田进行了除草试验,获得了较理想的结果。一、五氯酚钠的除草效果在芽前每亩施用65%五氯酚钠原粉1斤、1.5斤兑水300斤喷雾处理(试验小区为0.01亩,三次重复,下同)在不揭膜的前提下,防除禾本科、莎草科、石竹科等杂草(狗牙根除外)
Chemical weeding is an important part of promoting peanut-covered mulch. We use the existing and economic two herbicides - pentachlorophenol sodium, weed ether, in the film peanut field weeding test, obtained the more satisfactory result. First, the weed control effect of sodium pentachlorophenate In the pre-emergence application of 65% sodium pentachlorophenol 1 kg of raw powder, 1.5 kg watered 300 kg spray treatment (test plot of 0.01 acres, three replicates, the same below) is not exposed Under the premise of film, weed control (Gramineae, Cyperaceae, Caryophyllaceae and other weeds (except bermudagrass)
