在蚯蚓养殖中往往遇到卵茧孵化率低的问题,给蚯蚓的发展带来一定的影响。蚯蚓卵茧孵化所需的时间及每个卵茧孵出的幼蚓数,与蚯蚓的种类和孵化时的温度、湿度等生态因子有密切关系。我们在养殖“太平2号”蚯蚓过程中,通过多年的实践摸索,初步体会到,要提高蚯蚓卵茧的孵化率,就必须定时清理卵茧。具体作法是:在气温15～28℃的季节里,每隔10～15天将卵茧从蚯蚓养殖床内清理出来,放到预先准备的蚓床上进行孵化。蚓床必须通气良好,湿度控制在56～66%之间。在这种条件下,卵茧孵化15～20天便可出
In the earthworm breeding often encounter the problem of low hatching rate of egg cocoon, to the development of earthworms bring a certain impact. The time required for hatching egg worm cocoon and the number of young bugs hatched from each egg cocoon are closely related to the types of earthworms and the ecological factors such as temperature and humidity during incubation. During the process of breeding “Taiping 2” earthworm, through our many years of practical exploration, we initially realized that to raise the hatching rate of earthworm eggs and cocoon, we must regularly clean the eggs and cocoon. The specific approach is: in the temperature of 15 ~ 28 ℃ season, every 10 to 15 days from the earthworm eggs in the cocoon clean out bed, placed in bed prepared wormholes hatch. Earthworm bed must be well-ventilated, humidity control between 56 ~ 66%. In this condition, egg cocoon hatch 15 to 20 days will be out
