添加調整材對雞糞堆肥之影響

Effects of add Adjustment Material to Composting of Chicken Manure.

指導教授 : 余伍洲

摘要


我國農民長期習慣使用未經醱酵腐熟之生雞糞作為植物肥料,因生雞糞具低碳高氮性質、肥份足、價格低廉及取得方便,早期農民已廣為使用。使用未經醱酵腐熟之生雞糞若無妥善覆土,易孳生蚊蠅、惡臭,污染水源或土地,對居家環境衛生影響;又長期使用生雞糞為植物肥料,亦有導致土壤中重金屬含量超過標準之虞。 本研究主要以雞糞為堆肥主體,混合不同調整材進行堆肥化實驗,包括木屑、迴流菌種、廢棄養菇木屑,以腐熟堆肥標準C/N需> 10為依據,混合生雞糞與調整材,使其初始C/N為11左右,並經由物理、化學及生物分析結果比較。在溫度、含水率、pH 、C/N 及發芽率的變化結果顯示,太空包堆肥於發酵高溫期45℃以上持續16天為最久,各腐熟堆肥pH值皆為弱鹼性。在化學分析部分,添加迴流菌種、木屑及太空包之 C/N皆為10以上,符合堆肥C/N標準。本研究結果顯示,添加迴流菌種、木屑及太空包之堆肥,雖C/N未達最佳初始值25~30間,但於堆肥化過程中仍可達腐熟;發芽率實驗係以太空包為調整材之堆肥最佳,並以此堆肥作為作物實驗之肥料,結果顯示作物生長情形隨著添加肥料量增加,雖以四倍推薦添加量最佳,但兩倍與四倍添加量並無太大差異。

Farmer always applying the fresh chicken manure in producing crops in our country, because of the fresh chicken manure has high nitrogen and low carbon, fertility and cheaper. However, It also generates a lot of environmental problems in soil and atmosphere. This study used the fresh chicken manure for the main materials, adding and mixing the different adjustment materials, such as sawdust, reflow bacterium and mushroom cultivation waste bags. Adjust the initial carbon-nitrogen ratio to about 11 and analyze the Ferment mixture in physics, chemistry and the biological. In the variation of temperature, moisture content, pH, C/N and germination ratio, showed that the regulation above 45℃ high temperature with compost D (mixed by mushroom cultivation waste bags) for 16 days, the PH of all the compost was alkaline. And the variation in carbon-nitrogen ratio (C/N) was lower than initial but still above 10, was comply with the C/N standard. The study results show that, the compost for mixed by sawdust, reflow bacterium and mushroom cultivation waste bags, even though the initial C/N less than 25 to 30, the composting still could be complete. The pot experiment used the compost D for plant food, which was the best of the result of seed-germination percentage test. The report showed the grain yield will be higher with the plant food increase, but the 2DF (double of the recommended conventional nitrogen application) was not significantly higher than the 4DF (quadruple of the recommended conventional nitrogen application).
