摘　　要：为研制出高效油茶专用有机肥,选择不同分量鸡粪、油茶壳、茶籽饼,并配合相应氮磷钾硼速效肥比例和不同类型发酵剂,采用4因素3水平正交试验设计和试验实施,然后对发酵完全的各种有机肥养分相关指标进行测定并进行肥效试验,结果表明:不同原料配方对有机肥全钾和有机质含量影响极显著,油茶壳和茶籽饼对全钾含量影响最大,鸡粪对有机肥中有机质含量影响最大;处理8全氮含量较高,处理9全氮含量最低,处理4速效氮含量最高,处理6速效氮含量最低;处理1全钾含量最高,处理5全钾含量最低,处理6速效钾含量较高,处理4速效钾含量最低;处理7全磷含量较高,处理9全磷含量最低,处理3速效磷含量较高,处理4速效磷含量最低;处理1有机质含量最高,处理6有机质含量最低,不同配方有机肥呈中性;不同配方和不同发酵时间有机肥对墨西哥玉米草生物量相关指标影响差异极显著,施配方7有机肥处理玉米草生长最高,施配方5有机肥处理玉米草地上部分鲜重最大,施配方8有机肥玉米草地上部分干重最大。In order to study high efficiency special organic fertilizer of oil-tea camellia,made chicken manure,oil-tea camellia peel,oil-tea camellia seed dregs,NPKB and different fermentation agents as organic fertilizer raw materials,apply 4 factors 3 levels orthogonal experiment design and comparison test of fertilizer efficiency,then measured organic fertilizer relevant indicators,the results showed that：Different materials had significant effect on organic fertilizer potassium and organic matter content,oil-tea camellia peel,oil-tea camellia seed dregs,had significant effect on the total potassium content organic fertilizer,the manure had significant effect on organic matter content;Formula 8 total nitrogen content was higher,formula 9 total nitrogen content was the lowest,formula 4 available nitrogen content was the highest,formula 6 available nitrogen content was lowest;Formula 1 total potassium content was the highest,formula 5 total potassium content was lowest,formula 6 available potassium content was higher,formula 4 available potassium content was the lowest;Formula 7 total phosphorus content was higher,formula 9 total phosphorus content was lowest,formula 3 available phosphorus content was higher,formula 4 available phosphorus content was the lowest;Formula 1 organic matter content was the highest,formula 6 organic matter content was the lowest,different formula organic fertilizer pH was neutral;The effects of different fertilizer and different fermentation stages on the Purus frumentum the biomass were significant,Formula 7 organic fertilizer treatment growth of Purus frumentum was the highest,formula 5 organic fertil-izer treatment fresh weight of Purus frumentum was the heaviest,formula 8 organic fertilizer treatment dry weight of Purus frumentum was the heaviest.
