摘　　要：本试验以农村养蚕生产普通育型式进行,设置5龄二回育、三回育、四回育、五回育四个大区,以五回育为对照进行比较,结果表明:除二回育区外,其他各试验区与对照区在各项生理、经济指标上无明显差异,其中三回育区在健康性、茧质方面还优于对照区.而且,三回育比五回育提高给桑工效1.2倍,劳动效率高.<ABSTRACT>The conventional rearing method was adopted in a trial with fifth instar silkworms, which were given two, three, four or five feedings per day. Three - feeding or four - feeding treatments showed no significant difference from the control (five feedings per day) in various physiological and economic indices. Three - feeding treatment were superior to the control in silkworm health and cocoon quality and raised mulberry leaf feeding efficiency by 120 percent.
