摘要：[目的]研究在蚯矧養(yǎng)殖過程中使用沼液作保濕液對蚯蚓生長的影響，為沼液廢物資源化利用、蚯蚓養(yǎng)殖使用沼液提供參考。[方法]用赤子愛勝蚓為試驗神，在經(jīng)發(fā)酵處理的和未經(jīng)發(fā)酵處理的牛糞2個紐中養(yǎng)殖，定期施加沼液保持濕度，以施加清水作對照，分別就沼液對蚯蚓生長、繁殖及孵化的影響進行研究。[結(jié)果]在經(jīng)發(fā)酵處理的牛糞組中施加沼液，蚯蚓的日增重倍數(shù)增加明顯；再用挑出的蚓繭試驗，發(fā)現(xiàn)施加沼液對其孵化有負影響。表明在蚯蚓的生長階段，沼渡的添加對于成蚓和幼蚓的生長都有明顯的促進作用；但在蚯蚓的繁殖階段，沼液的添加不利于其繁殖以及蚓繭的孵化。[結(jié)論]在實際應用沼液養(yǎng)殖蚯蚓時，應將沼液的使用范圍限制在蚯蚓的生長階段，繁殖與孵化階段不宜使用。

    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．a(chǎn)rched 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．

當前，我國畜禽養(yǎng)殖業(yè)迅速發(fā)展，養(yǎng)殖小區(qū)數(shù)量急劇增多，同時也給環(huán)境帶來了巨大壓力。為解決畜禽糞便污染問題，大多養(yǎng)殖小區(qū)配套建設(shè)了沼氣池，將畜禽糞便及沖洗水進行厭氧處理。沼渣沼液中含有N、P、K、Be、Cu、Fe、Mn、Ca、Zn等元素，以及大量的有機質(zhì)、多種氨基酸和維生素等，可作為優(yōu)質(zhì)有機肥為作物提供營養(yǎng)。刺激和調(diào)節(jié)作物生長¨‘31。同時沼渣可加工制成顆粒肥，養(yǎng)殖生產(chǎn)食用菌和蚯蚓。沼液則多用于直接葉面施肥、浸種、拌飼料喂養(yǎng)家畜、追肥等HJ。沼液既能增加作物產(chǎn)量、提高品質(zhì)，增強作物抗逆性、抗病蟲害特性，也可用作飼料添加劑使家畜提前出欄、肉質(zhì)提高，提高雞的產(chǎn)蛋率，沼液進入魚塘還可提高魚的產(chǎn)量，增強魚的抗病性等”
