摘　　要：文章主要概述了植物的氯素营养及科学施用含氯化肥三准则Chlorine is an essential element of plant nutrition.Based on twenty thorough and systematic studies on chlorine nutrition of plant and chlorine\|containing fertilizers three new theoretical ideas are proposed. (1)“Chlorine tolerance” and “critical value of chlorine tolerance of crop”.Plant chlorine tolerance can be divided into three types:(A)Crops of strong chlorine tolerance.It means under the condition of chlorine content of soil>600 mg/kg,the crops can grow normally.(e.g.beet cotton,rice,cucumber,etc.)(B)Crops of medium chlorine tolerance.The crtical chlorine tolerance values are 300～600 mg/kg.(e.g.wheat,maize,tomato,eggplant,soybean,etc.)(C)Crops of weak chlorine tolerance:The crops critical chlorine tolerance values are 150～300 mg/kg.(e.g.potato,sweet potato,tobaccos,grape,apple,etc.) (2)Chlorine allowance of soil.It is the differece between the critical value of chlorine tolerance of plant and chlorine\|content of soil.This term cimplies that the higher the chlorine allowance of soil,the much chlorine\|contained fartilizer can be applied to the soil.\;(3)The residual chlorine content in soil is nearly a constant.Accumulation effect of residual chlorine content not exists in the soil.\;These ideas will be beneficial to the application of Chlorine\|contained fertilizers and the development of the “United\|soda” Process.
