中文摘要 | 本試驗採用春作高粱-宿根高粱-秋作玉米之輪作系統,自1988年秋 作玉米迄1991年宿根高粱三年共計九期作,試區分別設于彰化縣埤頭鄉鹼性粘 板岩沖積土及台中縣外埔鄉酸性紅壤地區,以探討乾豬糞施用之效應。試驗結果 顯示,施用乾豬糞處理對玉米及高粱之株高、穗重、千粒重及子實產量均有顯著 效果,且該兩試區之結果頗為一致。以子實產量而言,不同期作及作物種類對乾 豬糞之施用適量即不同。秋作玉米以施用乾豬糞20t/ha配合化學肥料處理之產量 最高,春作高粱及宿根高粱則以施用乾豬糞10t/ha配合化學肥料之處理較適當。 且施用乾豬糞處理可增加土壤中玉米根密度,促進根系分佈,其效果可達土壤深 度30cm。 |
英文摘要 | Field trials were carried out at Changhua (slightly alkaline slate alluvial soil) and Taichung (strongly acidic red earth) under the sorghum-ratooned sorghum-corn cropping sequence during 1988-1991. Results showed that the application of hog manure 10 or 20t/ha increased significantly the plant height, ear weight (or panicle weight), 1000-grain weight and grain yield of the test crops or two sites of experiment. The yield of fall corn response best to the treatment of hog manure 20t/ha in combination with recommended chemical fertilizers. The spring sorghum and ratooned sorghum had a better grain yield under the application of hog manure 10t/ha and chemical fertilizers. The hog manure application significantly increased the density of rooting system in the 30cm depth of surface soil. |
