如何科学施用含氯肥料
How to Scientifically Apply Chlorine Containing Fertilizers

较多菜农、药农、茶农、烟农等在购买肥料时走入误区，总是“闻氯色变”“望氯止步”，在种植马铃薯、茄科蔬菜、黄连、茶叶、烟草等“忌氯作物”时，不敢涉足含氯肥料，致使肥料投入增加，而作物产量和品质并未得到提升，甚至反而下降。为正确指导含氯肥料的科学选择和施用，通过查阅大量文献和取样检测利川耕地氯含量，在本文中较详尽地介绍了氯元素的作用及丰缺表现，作物对氯的敏感程度分类，土壤中氯离子的含量及分布，以及如何因土、因作物、因时期科学施用含氯肥料，以提高农业技术推广工作者及广大种植户的正确认识，从而实现农业节本增效。
Many vegetable farmers, pharmaceutical farmers, tea farmers, tobacco farmers, and others fall into the wrong trap when purchasing fertilizers. They always “smell chlorine and turn pale” and “wait for chlorine to stop.” When planting “chlorine free crops” such as potatoes, eggplant vegetables, coptis, tea, tobacco, etc., they dare not step into chlorine containing fertilizers, resulting in an increase in fertilizer input, but crop yield and quality have not been improved, or even decreased. In order to guide the scientific selection and application of chlorine containing fertilizers correctly, by consulting a large number of literature and sampling to detect the chlorine content in Lichuan arable land, this article provides a detailed introduction to the role and abundance and deficiency of chlorine element, the classification of crop sensitivity to chlorine, the content and distribution of chloride ions in soil, and how to scientifically apply chlorine containing fertilizers according to soil, crop, and period, in order to improve the correct understanding of agricultural technology extension workers and farmers, thus achieving cost saving and efficiency enhancement in agriculture.
