摘　　要：本文用试验方法探讨了精子密度对皱纹盘鲍卵的受精率及受精卵畸形率的影响。结果表明:在卵的密度为1—100个/毫升的条件下,精子密度在10万—100万个/毫升时受精率较高,低于1万个/毫升则受精率偏低,高于100万个/毫升部分卵脱膜畸形。精子密度在10万—100万个/毫升范围内受精率随精子密度的增大而稍有提高。精、卵密度较大时,采取及时、充分洗卵的方法有利于降低受精卵的脱膜畸形率及提高卵的受精率。The density of sperm has a large effect on the fertilization rate and monstrosity rate of fertilized eggs of abalones. When sperm density is less than 10~4/ml,the fertilization rate is very low. When it is 10~5-10~6/ml, the fertilization rate is high. If it is over 10~6/ml, the membrane of the fertilized eggs fall off easily producing abnormal eggs.
