含氯化肥是指含有氯离子的一类化肥,常用的含氯化肥有氯化铵、氯化钾以及以氯化铵、氯化钾为原料配制而成的复(混)合肥、专用肥、配方肥等。由于含氯化肥的盐分指数高,加上氯离子较难被土壤吸附,施入初期会提高土壤中氯离子的浓度,从而容易产生“氯害”。在农业生产中常见因含氯化肥施用不当,而造成烧种、伤苗等现象。为防止因施用含氯化肥造成的危害,农民朋友施用含氯化肥要四忌。
Chloride-containing fertilizer refers to a class of chemical fertilizers containing chloride ions, commonly used chloride-containing ammonium chloride, potassium chloride and ammonium chloride, potassium chloride as raw materials prepared from complex (mixed) Hefei, special fertilizer, Fertilizer and so on. Due to the high salinity index of chloride-containing fertilizers and the more difficult adsorption of chloride ions on the soil, the chloride ion concentration in the soil will increase at the initial stage of application, resulting in “chlorine damage” easily. Common in agricultural production due to improper use of chlorine-containing fertilizer, resulting in burning seedlings, wounding and other phenomena. To prevent the harm caused by the application of chlorinated fertilizers, farmers friends to use chlorine-containing fertilizer to avoid the four bogey.
