摘要： 為探索工業(yè)廢棄茶渣在茶園培肥中的有效利用技術(shù),采用工程生物蚯蚓處理廢棄茶渣與牛糞和稻稈的復混物料,研究了蚯蚓在茶渣復混物料中的生長繁殖情況,以及處理前后物料肥力屬性的變化。結(jié)果表明：蚯蚓在茶渣含量20%的復混物料中可以正常生長繁殖,并完成對復混物料的肥料化處理。20%茶渣復混80%牛糞的物料對蚯蚓的繁殖更有利,而20%茶渣復混80%稻稈對蚯蚓的生長更有利。蚯蚓處理廢棄茶渣復混物料會消耗一定有機碳,同時提升氮磷鉀等礦質(zhì)養(yǎng)分的有效性,氮素有效性較無蚯蚓對照組提高23.24%~46.96%,磷素有效性提高16.26%~25.63%,鉀素有效性提高14.08%~33.84%。綜上所述,蚯蚓生物處理技術(shù)可應用于廢棄茶渣肥料化利用中,加快物料降解速度,但要復混牛糞、稻稈等其他物料,廢棄茶渣含量20%是一個可行的復混比例。

Abstract: To explore the effective use of industrial tea residue in tea garden, the engineering earthworms were used to treat tea residue mixed with cattle waste and rice straw in this experiment. The growth and reproduction of earthworms as well as changes of fertility properties in tea residue compounds were also studied. The results showed that earthworms could grow and breed normally in the compound materials with 20% tea residue and the vermicomposting of tea residue compound materials can be successfully completed. Compound materials with 20% tea residue and 80% cattle waste were optimal for breeding of earthworms. While materials with 20% tea residue and 80% rice straw were optimal for growth of earthworms. Some organic carbons were consumed during the vermicomposting process. While the efficiency of nitrogen, availability of phosphorus and efficiency of potassium were increased by 23.24%-46.96%, 16.26%-25.63% and 14.08%-33.84% respectively. In summary, the earthworm biological treatment could be applied for the utilization of tea residue as fertilizer. However, a mixture of tea residue with cow dung, rice straw and other materials was needed, with an optimal tea residue content of 20%.

Key words: earthworm, tea residue, cattle waste, rice straw
