摘　　要：为探索少回育对贵蚕9号经济性状的影响,开展了不同饲育回数试验研究。结果表明,二回育区病弱蚕数要显著高于三回育区和四回育区,四龄蚕结茧率显著低于四回育区;二回育区饲养管理用工时间最少,分别比三回育和四回育节约用工15.8%和29.4%;二回育区用叶量较少,分别比三回育和四回育节约用叶10.0%和14.01%。二回育区公斤茧用叶量最少,产茧量、克蚁收茧量和蚕茧产值最低,但公斤桑叶经济产值最高。To explore the effect of less feeding times to rear Guican 9 on its economic traits,the experiment on different feeding times was conducted.The results show that the number of the sick and weak for silkworms feeding twice a day is much higher than that feeding three and four times a day,and the cocoon rate for four instar silkworm was significantly lower than that of the silkworms feeding four times a day;the labor time for management of silkworms feeding twice a day was the least,15.8% and 29.4%respectively less than that of silkworms feeding three and four times a day;silkworms feeding twice a day consumed the least leaves,10%and 14.01%less than the other two groups.It is concluded that the leaf consumption,cocoon yield and cocoon production per silkworm were all the least,but the economic output value of mulberry per kg was the highest.
