中文摘要 | 家畜禽排泄物為臺灣地區農業有機廢棄物主要來源之一,其中以豬、牛、雞等排泄物為大宗。本試驗目的在探討牛糞及豬糞堆肥長期施於狼尾草地後,對其產量、植體成分及土壤肥力之影響。以狼尾草臺畜草2號為供試品種,分成不施肥、全施化肥N:P2O5:K2O=920:144:450kg/ha/year、與牛糞及豬糞堆肥分別代替全施化肥中一半氮素(即460kg)及全部氮素(即920kg)等六種處理。經過7年連續施用結果,在施用等量氮素下,平均株高和總產量以全施牛糞堆肥及半量化肥加半量牛糞堆肥最高,全施豬糞堆肥處理較差,但仍與全施化學肥料處理間沒有顯著差異,又施用牛、豬糞堆肥可增加植體中磷、鈣、鎂、銅及鋅等含量,降低鉀╱(鈣+鎂)比值。狼尾草地施用牛、豬糞堆肥後,使酸性土壤pH及電導度提高,增加土壤中有機質、總氮、有效性磷、交換性鈣、鎂與酸可抽出銅及鋅的含量,尤其施用豬糞堆肥使銅和鋅含量顯著增加,因豬糞中含有較多之銅或鋅;因此牛、豬糞堆肥施用於狼尾草地後,可代替化學肥料,保持或增加產量,改善品質(降低K/(Ca+Mg)比),及提高土壤地力。 |
英文摘要 | Animal wastes are the major sources of organic fertilizer in agriculture. Most of them come from the wastes of hog, cattle and chicken. The objectives of the study were to determine the effects of cattle and hog manures on forage yield, chemical compositions of napiergrass (Pennisetum purpureum) and soil fertility for long term application. Napiergrass CV. Taishi No.2 was applied with 6-different fertilizers, i.e., no fertilizer, chemical fertilizer applied with N : P2O5 : K2O = 920 : 144 : 450 kg/ha/year, all cattle or hog manure equivalent to N 920 kg/ha, and one half on N replaced by cattle or hog manure. Seven years after application, the plant height and total forage yield for the plot applied with cattle manure only and those for the plot with one halt of N replaced by cattle manure were the highest among treatments. The plot with hog manure only showed no difference from which received chemical fertilizer only. The contents of P, Ca, Mg, Cu and Zn in the plants were increased and the ratio of K/(Ca+Mg) was decreased when the plots were applied with cattle and hog manures. The pH values and the electric conductivity were increased in soil. The contents of organic matter, total N, available P, exchangeable Ca and Mg, extractable Cu and Zn were increased in soil after applying with cattle and hog manures. Both contents of Cu and Zn were significantly increased in soil when hog manure rich in Cu and Zn was applied. The results showed that chemical fertilizer could be replaced by cattle or hog manure to maintain forage production and improve forage quality and soil fertility. |
