中文摘要 | 本研究目的在探討堆肥化前,有機物基質特性及用量比例不同對堆肥 中營養要素含量及品質之影響,試驗堆肥基質以香菇木屑太空包廢料為主,再依 重量比分別與(A)雞糞10%、(B)雞糞10%、尿素及過磷酸鈣各0.4%(C)雞糞40% 等混合組成三種配方處理,其堆肥化前基質中碳氮比值分別為(A)29.9、(B)22.7、 (C)18.9。試驗結果顯示,腐熟堆肥中營養要素含量以C配方處理最高,其次為B 配方及A配方處理,堆肥化過程中各配方處理間氮成分損失率達到顯著差異水 準,A處理為31.4%,B處理為36.9%,C處理為48.3%,顯示氮成分損失率隨 基質中碳氮比值之降低而增加。磷、鉀、鈣、鎂及碳等成分損失率則未達顯著差 異水準。添加之尿素態氮在堆肥化過程中有54.6%(12.06kg)損失,25.8%(5.68kg) 轉化成有機態,19.6%(4.34kg)成為無機態留存於堆肥中,添加的過磷酸鈣則約有 原添加磷量的74.6%(2.81kg)及原添加鈣量的68.7%(7.06kg)留存於堆肥中。在堆 肥化前基質中添加化學肥料0.4%(B配方)及提高雞糞用量比例(C配方)等處理, 會增加腐熟堆肥中無機態氮含量及電導度,並降低堆肥水萃取液之種子發芽率指 數。 |
英文摘要 | The objective of this research was to assess the effects of the characteristics and application rates of mushroom wastes on the nutrient contents and qualities of composts. Experiment was conducted with three treatments by piling mushroom waste with A) chicken waste 10%, B) chicken waste 10%, urea 0.4%, and superphosphate 0.4%, C) chicken waste 40%, by weight basis. The C/N ratios of raw materials of ingredient A, B, and C were 29.9, 22.7, and 18.9, respectively. The results showed that compost from C ingredient had the highest nutrient contents than those of the other composts. The loss of total nitrogen of different treatments were significant during composting, however the loss of P, K, Ca, Mg, and C in different treatments were not significant. The loss of N in treatments A, B, and C during composting were 31.4%, 36.9%, and 48.3%, respectively. However, the loss percentage of N increased as the C/N of raw material lowered. During composting the added urea-N would be transformed into inorganic-N (19.6%), into organic matter (25.8%), or lost (53.2%). The retention parts of P and Ca in compost from the addition of superphosphate were 74.6% and 68.7%. Therefore, treatments of addition of urea and superphosphate (B ingredient) and high application rate of chicken waste (C ingredient) could increase the contents of mineral-N and EC in compost and decrease the seed germination index. |
