摘要
为确定在蚯蚓规模养殖中使用沼液作保湿水对蚯蚓生长的影响,用赤子爱胜蚓作试验种,在经有效微生物(EM)处理过的牛粪养殖床(75 m2)中进行试验,每隔5 m交替投加沼液,每次施加量约为5 m3,间隔时间为7 d,并设投加清水为对照组。结果表明,在1个月的试验期后,与施用清水比较,沼液的添加对蚯蚓生长有促进作用,使蚯蚓质量增加12%;施加沼液组还促使蚯蚓的形态变粗,长度变化不明显。说明蚯蚓养殖中使用沼液作保湿水可行,对蚯蚓养殖生产具有正效益,同时使沼液废物资源化利用。
In this paper,the effect of application of biogas liquid to keep wet on earthworm breeding was studied.The results showed that biogas liquid significantly promoted the growth of earthworm in the breeding process.It conld increase the weight by 12% of earthworms.This indicated that biogas liquid could be used to keep wet for earthworm breeding in practice.
