摘要:為研制出高效油茶專用有機肥,選擇不同分量雞糞、油茶殼、茶籽餅,并配合相應氮磷鉀硼速效肥比例和不同類型發酵劑,采用4因素3水平正交試驗設計和試驗實施,然后對發酵完全的各種有機肥養分相關指標進行測定并進行肥效試驗,結果表明:不同原料配方對有機肥全鉀和有機質含量影響極顯著,油茶殼和茶籽餅對全鉀含量影響最大,雞糞對有機肥中有機質含量影響最大;處理8全氮含量較高,處理9全氮含量最低,處理4速效氮含量最高,處理6速效氮含量最低;處理1全鉀含量最高,處理5全鉀含量最低,處理6速效鉀含量較高,處理4速效鉀含量最低;處理7全磷含量較高,處理9全磷含量最低,處理3速效磷含量較高,處理4速效磷含量最低;處理1有機質含量最高,處理6有機質含量最低,不同配方有機肥呈中性;不同配方和不同發酵時間有機肥對墨西哥玉米草生物量相關指標影響差異極顯著,施配方7有機肥處理玉米草生長最高,施配方5有機肥處理玉米草地上部分鮮重最大,施配方8有機肥玉米草地上部分干重最大。
