我国是目前世界上生产氯化铵最多的国家,年产在百万吨以上。随着氯化铵及其它含氯化肥(氯化钾、氯磷铵复合肥等)在农业生产中的大量应用,使大量的氯离子进入环境,参与土壤——植物体系的循环,氯素对作物的生长,产品品质及对土壤性质的影响等问题,引起了广大农业科技工作者的关注。本文就应用同位素~(36)Cl示踪研究几种不同类型的植物对氯素的吸收、分布,为合理施用含氯化肥提供科学依据。 一、试验材料与方法 试验采用盆栽结合理化分析。供试同位素~(36)Cl从英国进口,由中国农科院原子能利用研究所合成放射性氯化铵作为示踪肥料。烟草、棉花不同氯离
China is the country that produces the most ammonium chloride in the world at present, with an annual output of more than 1 million tons. With the extensive application of ammonium chloride and other chlorinated fertilizers (potassium chloride, ammonium chloride ammonium fertilizer, etc.) in agricultural production, a large number of chloride ions enter the environment and participate in the cycle of the soil-plant system. Crop growth, product quality and the impact on soil properties and other issues, has aroused the attention of the majority of agricultural scientists. In this paper, the application of isotope ~ (36) Cl tracer study of several different types of plants on the absorption of chloride, distribution, in order to provide a scientific basis for the rational use of chlorine-containing fertilizers. First, the test materials and methods The experiment using potted physical and chemical analysis. The isotope of test (36) Cl is imported from the United Kingdom and radioactive ammonium chloride is synthesized as a tracer fertilizer by the Institute of Atomic Energy Utilization of Chinese Academy of Agricultural Sciences.
