摘　　要：研究采用随机区组试验设计,设置了蚯蚓养殖处理养殖场牛粪和农户牛粪2种处理,比较研究了不同处理下苗床的养分特性、温度、含水量、接种密度变化对赤子爱胜蚓生长和繁殖及消解的影响,旨在筛选出蚯蚓养殖处理牛粪的最佳适宜条件。试验结果表明:(1)蚯蚓养殖处理后的农户牛粪较养殖场牛粪更适宜蚯蚓生存和繁殖,处理后的农户牛粪养分含量相对养殖场的高,其中有机质平均含量38.07%、全氮含量1.02%、全磷含量0.85%、全钾含量1.03%;(2)在温度保持在18.6℃、蚯蚓苗床含水量保持在28%左右最有利于蚯蚓的生存和繁殖;(3)蚯蚓养殖最佳接种密度为每平方米蚯蚓含蚯蚓粪8 kg下农户的牛粪消解效果最好。Randomized block design experiment was usesd,the cow dung treated with earthworm cultivation and cow dung from farmers’cows were set up to study on effects of seedbed nutrients,temperature,water content and the density of inoculation on growth and reproduction of lumbrukinase and digestion of Eiseniafaetida,which is expected to select the optimal treatment condition of cow dung with earthworm cultivation.The results showed that:(1)Farmer’s cow dung treated with earthworm cultivation was more suitable for the survival and reproduction of earthworms,and the nutrient contents were higher,including 38.07% organic matter,1.02% total nitrogen,0.85% total phosphorus and 1.03% total potassium.(2)The survival and reproduction of earthworms were best when the temperature was 18.6℃ and the water content of earthworm bed was about 28%.(3)The best inoculation density of earthworm cultivaiton was 8 kg earthworm manure per square meter,and the digestion effect of cow dung was the best.
