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.
