摘要

台灣農地面積占地廣大，每年所產生之農業廢棄物亦具有相當大之數量；工業革命以後，化學肥料開始大量的使用，因為化學肥料能快速表現在作物的產量上，因此，傳統的有機肥料慢慢開始被化學肥料所取代，在經過長期且大量的施用化學肥料以及少用有機肥料的結果，土壤地力日益衰竭，甚至導致原有生態體系的平衡遭受破壞。直到今天，人類環保意識逐漸抬頭，所以越來越重視以環境為導向的有機農業。有鑑於此，全球農業界倡導農業永續性經營理念，期望經由有機質肥料的循環利用，維持作物較佳之生育環境。因此，傳統的有機農業再次被人類所重視，而各國紛紛對有機農業做進一步的研究。現今為推廣有機農業，將減少或限制化學肥料的施用，而在往後台灣地區之農業經營，將以有機農業之模式而進行規範。

本研究採用田間試驗方式進行，劃分為24個小區域，於每個區域配置禾本科與豆科類植株單植與混植，並於部分區塊施以農畜產廢棄物做為肥料，之後加以觀察並予以比較。

研究結果顯示，種植盤固草在施用有機質肥料與否及單植或混植上，對於土壤養分之影響無顯著性，種植Survenola草在與豆科混植上具有其顯著性。種植盤固草與種植Survenola草在施用有機質肥料與否於植體養分的影響上，無明顯之顯著性；而種植盤固草在單植、混植之植體氮含量與鉀含量上具有其顯著性，種植Survenola草則在單植、混植之植體氮含量與磷含量有顯著性。而在產量分析中，施用有機質肥料與單植、混植上均無顯著性。

Taiwan occupies vast area of agricultural land, agricultural waste generated every year and also have a large quantity. After the industrial revolution, the use of chemical fertilizers in large quantities, because chemical fertilizers can be quickly reflected in the yield of the crop. Therefore, the traditional organic fertilizer slowly being replaced by chemical fertilizers, after a long and substantial use of chemical fertilizers and organic fertilizers less the result of increasing soil fertility failure, even lead to the balance of the original ecosystem damage. Even today, human beings have begun to gain awareness of environmental protection, so more and more attention to environment-oriented organic agriculture. In view of this, the global agricultural community advocacy agricultural sustainability philosophy, expectations by the recycling of organic fertilizers to maintain crop growth environment for the better. Therefore, the traditional organic farming again valued by humans, while all of the countries for further study of organic agriculture. Now for the promotion of organic agriculture, will reduce or limit the application of chemical fertilizers, and in the future of agricultural operations in Taiwan, the pattern of organic agriculture will be regulated.

In this study, conducted field trials, divided into 24 small areas in each region configuration grass and leguminous plants with a single class of mixed planting plants, and in some blocks of agricultural animal waste as fertilizer to impose, to be observed after and compared.

The results showed that planting Pangolagrass or in the application of organic fertilizer and planting on a single plant or mixed, for no significant effect of soil nutrients, planting grass and legume mixed Survenola plant had its significant. Planting Pangolagrass and Survenola grass in the application of organic fertilizer nutrients in the implant, no obvious significant. The planting Pangolagrass single planting, mixed planting of vegetation nitrogen content and potassium content had its significant, planting Survenola mixed in the planting or single plant of plant nitrogen content and phosphorus content are significant. In the output analysis, application of organic fertilizer and planting on a single plant or mixed with no significant.
