【摘要】 应用Excel软件中的曲线方程分析判断敌敌畏农药对两广二号家蚕的安全间隔期。结果表明:敌敌畏1 000倍液的安全间隔期是6d多,其数学模型为幂函数曲线方程:y=88.0653x-1.834。本方法克服以往家蚕的农药安全期无数学模型可循或使用的BASIC方法陈旧繁杂的缺点,也避免英文统计软件SPSS难以在农村普及的不足,是一种计算更方便、更易推广的农药安全期分析新方法,它有助于提升蚕桑产业中病害防控体系的智能化水平。更多还原

【Abstract】 The fitting curve equation of the safe intervals of DDVP for LiangGuang II silkworms was analyzed and judged through the application of Excel.The results indicate that the safe interval of DDVP is more than 6 days at a 1000 fold dilution.Moreover,the mathematical model of the method is a power function curve equation: y=88.0653x-1.834.Due to not only overcoming some lacks including having no mathematical model of the safety interval of pesticides for silkworms to abide by but also avoiding some shortcomings of SPSS which is written in English such as being too hard to popularize in rural areas,this approach is significantly more accurate,rigorous and simpler in comparison with the BASIC method which is too obsolete and complicated.Therefore,this new approach is contributive to promote the intelligentization level of the prevention and control system of disease for sericulture.更多还原
