我分场大面积土地处于七星河中下游,地势平坦,适于大面积机械化作业。为了实现农田除草化学化,提高粮食商品率,1978年我们引进了从意大利进口的大豆化学除草剂氟乐灵,进行了大面积生产示范和小区对比试验,灭草效果显著,深受群众欢迎。我们使用的氟乐灵是48％乳油,二硝基苯胺类芽前土壤处理剂。是黄橙色,pH值在6～7之间的可溶性乳剂。植物对该药的吸收部位与传导方向是:单子叶为芽鞘,双子叶为下胚轴,传导方向是向上,灭草原理主要是对次生根细胞分裂有严重抑制作用。用于播前全面施药,垧用药量0.75～1.5公斤。
I sub-area large area of land in the middle and lower reaches of Qixing River, flat, suitable for large-scale mechanized operations. In order to achieve chemical weed farming and improve food commodity rates, we introduced triphyllaide, a chemical herbicide of soybean imported from Italy, in 1978 and conducted large-scale production demonstration and plot comparison tests. The herbicide effect was remarkable and was well received by the public. The trifluralin we use is a 48% EC, a dinitroaniline pre-emergence soil treatment. Is a yellow-orange, pH 6 to 7 between the soluble emulsion. Plant absorption of the drug site and conduction direction are: monocotyledons sheath, dicotyledon hypocotyls, conduction direction is up, the main principle of the herbicide secondary root cell division has a serious inhibitory effect. For sowing before the full application, 垧 dosage 0.75 to 1.5 kg.
