摘要：[目的]研究在蚯矧养殖过程中使用沼液作保湿液对蚯蚓生长的影响，为沼液废物资源化利用、蚯蚓养殖使用沼液提供参考。[方法]用赤子爱胜蚓为试验神，在经发酵处理的和未经发酵处理的牛粪2个纽中养殖，定期施加沼液保持湿度，以施加清水作对照，分别就沼液对蚯蚓生长、繁殖及孵化的影响进行研究。[结果]在经发酵处理的牛粪组中施加沼液，蚯蚓的日增重倍数增加明显；再用挑出的蚓茧试验，发现施加沼液对其孵化有负影响。表明在蚯蚓的生长阶段，沼渡的添加对于成蚓和幼蚓的生长都有明显的促进作用；但在蚯蚓的繁殖阶段，沼液的添加不利于其繁殖以及蚓茧的孵化。[结论]在实际应用沼液养殖蚯蚓时，应将沼液的使用范围限制在蚯蚓的生长阶段，繁殖与孵化阶段不宜使用。

    Abstract： [Objective] 1he reference for the utilization of the biogag liquid as resource in earthworm—raising wag provided through the research 011 the effect of the biogas liquid a5 moisture liquid on the earthworm—raising．『Method 1 11le earthworm--Chizian being taken as experimental material，the effect of biogas liquid on carthwornl growth，multiplication and hatching was re．arched based on the design of the biogas liquid added into two treatments，in which tlle earthworm was cultured in the fermented and un—fermented dung，respective．for the moisture．keeping and the water treatment 1t8 CK．I Results The daily weight—increasing of earthworm was significantly promoted in the treatment that the earth． worln was cultured in the fermented durig and biogas liquid Wag added．The cocoon of earthworm was chosen for the hatching experiment and results showed that its multiplication was negatively affected by the addition of biogas liquid．Thus，the addition of biogas liquid had obviously promoting role in the growth of adult and young earthworm；but it was not conducive to the reproduction and hatching of earthworm． [Conclusion]In the practical appficafion of the biogas liquid in earthworm-raising，it could be apphed in the growth stage of earthworm and not，be used in its reproduction stage．

当前，我国畜禽养殖业迅速发展，养殖小区数量急剧增多，同时也给环境带来了巨大压力。为解决畜禽粪便污染问题，大多养殖小区配套建设了沼气池，将畜禽粪便及冲洗水进行厌氧处理。沼渣沼液中含有N、P、K、Be、Cu、Fe、Mn、Ca、Zn等元素，以及大量的有机质、多种氨基酸和维生素等，可作为优质有机肥为作物提供营养。刺激和调节作物生长¨‘31。同时沼渣可加工制成颗粒肥，养殖生产食用菌和蚯蚓。沼液则多用于直接叶面施肥、浸种、拌饲料喂养家畜、追肥等HJ。沼液既能增加作物产量、提高品质，增强作物抗逆性、抗病虫害特性，也可用作饲料添加剂使家畜提前出栏、肉质提高，提高鸡的产蛋率，沼液进入鱼塘还可提高鱼的产量，增强鱼的抗病性等”
