    【Abstract】 Objective To inquiry into the physiology toxicity of the herbicide butachlor on the myocardial of the loach.Methods In this text,we applied calculator living creature signal analysis system,observed the influence of the herbicide butachlor on the myocardial contractility and heart rate of the loach.Results It enunciated that butachlor can change the physiology function of myocardial, making the myocardial contractility to die down,the heart rate messed.Conclusion It suggests that using the herbicide should notice the environmental protection.
