摘　　要：1986～1989年在黑龙江省哈尔滨、辽宁省铁岭多点设置不同种子传毒率水平的试验区,调查测定SMV流行和有翅蚜发生、飞翔动态,共积累19组数据。采用Apple-Ⅱ计算机BASIC语言进行回归分析,分别推导出符合度较高的SMV流行中,长期预测式。预测式可在东北地区试用,若结合种子传毒率预测和产量损失估计使用,将显著提高SMV“综合治理”水平。<ABSTRACT> A series of Epidemiological experiment plots which have different seed-born rates ofsoybean mosaic virus were established in Harbin of Heilongjiang province and Teiling ofLiaoning province during 1986～1989, 19 sets of systematic data which reflected the rela-tionships between SMV epidemics and occurrence, flight of alate aphids were accumulated.Apple-II computer was used for regression analysis and calculation with BASIC language,the prodicting equations of long-period and mid-period were derived with 2-factors. If theseregression equations for prodicting the disease incidences of SMV were used together with themodels on seed transmission rate and yield loss estimate, it would benefitial to make deci-sion in SMV management.
