中药渣搭配牛粪对蚯蚓生长及物料理化性质的影响

Effects of traditional Chinese medicine residue with cow dung on earthworms growth and material physicochemical properties

为解决畜牧生产中大量粪污和中药渣对环境污染的问题,探索中药渣和牛粪资源化利用的新途径,试验设处理A[牛粪+黄藿口服液药渣(黄芪和淫羊藿煎煮后的药渣)]、处理B(牛粪+黄芪)、处理C(牛粪+淫羊藿)和处理D(牛粪,对照)对蚯蚓的后期幼蚓进行饲喂,观察各处理对蚯蚓的体重、体长以及最终的产茧量、蚓茧孵化时间和孵化率的影响。结果表明,4个处理下蚯蚓的生长趋势均为先升高后降低,黄藿口服液药渣可显著提高蚯蚓的生长和繁殖性能;蚯蚓堆肥可提高物料全氮含量和pH,降低有机碳含量,黄藿口服液药渣搭配牛粪进行堆肥还可提高堆肥产物全磷含量。

In order to solve the problem of environmental pollution caused by fecal waste in livestock production and traditional Chi⁃nese medicine residues,and to explore a new way of resource utilization of traditional Chinese medicine residues and cow manure,the experiment set treatment A(cow manure+residues of radix Astragalus and Epimedium after decoction),treatment B(cow manure+Astragalus),treatment C(cow manure+Epimedium)and treatment D(cow manure,control)to feed the late larvae of earthworms.The effects of these treatments on the weight,body length,cocoon production,incubation time and hatching rate of earthworms were observed.The results showed that the growth trend of earthworms increased first and then decreased under the four treatments.The resi⁃due of radix Astragalus and Epimedium after decoction could significantly improve the growth and reproductive performance of earth⁃worms.Earthworm composting could increase the content of total nitrogen and pH of materials,and reduce the content of organic car⁃bon.The composting of residues of radix Astragalus and Epimedium after decoction with cow manure could also increase the content of total phosphorus.
