臺東之土壤地力分布與施肥策略

台東地處台灣東南部，地形狹長，北起長濱鄉南迄達仁鄉，長度達200公理。縱谷地區有延平、鹿野、關山及池上、海端等鄉鎮均為農業精華地區，西依中央山脈與屏東、高雄及花蓮等縣為鄰，東部海岸山脈橫亙其中，臨海則有台東、太麻里、東河、成功、長濱等5鄉鎮市。全縣總面積351,525公頃；其中平原地區面積22,208公頃，占6.32%；山坡地區97,567公頃，占27.67%；高山地區231,750公頃，占65.93%。雖然平原與山坡地所占面積上不及高山地區之三分之ㄧ，卻有稻米及番荔枝兩大經濟作物之生產，享譽全台。本文討論有關台東縣之土壤分布與地力狀況，以及依土壤肥力測定之分析資料作為施肥推薦之策略，提供農友參考。土壤是由固體、液體和氣體三類物質組成的，固體物質包括礦物質、有機質和微生物等，液體物質主要指土壤水分，氣體是存在於土壤孔隙中的空氣。這三類物質為提供作物必須的生長條件，也是土壤肥力的物質基礎。

Taitung is situated at southeast Taiwan, the terrain is long, north south the long shore township up to reaches the kind township, the length reaches 200 axioms. The longitudinal valley area has extends even, villages and towns and so on in Lu Yeh, Mt. Guanshan and pond, sea end for the agricultural essence area, west according to county and so on Central Mountain Range and Bingdong, Gaoxiong and Hualian is the neighbour among, eastern part the seacoast sierra spans, has Taitung near the sea, too in the hemp, Dong River, the success, the long shore and so on 5 townships -ville. County-wide total area 3.51,525 million hectares; Plain area area 22,,208 hectares, account for 6.32%; The hillside area 97,,567 hectares, account for 27.67%; The mountain area 2.31,75 million hectares, account for 65.93%. Although the plain and the hillside occupy in the area to be inferior to the mountain area 1/3, actually has the paddy rice and production the annona squamosa two big industrial crop, enjoys a good reputation entire. This article discusses concerns soil of distribution and the soil fertility condition the Taidong County, as well as applies fertilizer strategy of the recommendation analysis material achievement according to the soil fertility determination, provides the agricultural friend to refer. The soil is by the solid, the liquid and the gas three kind of matter is composed, the solid matter including the mineral substance, the organic matter and the microorganism and so on, the liquid matter mainly refers to the soil moisture, the gas is exists in the soil hole the air. These three kind of matter for provide the crops to have growth condition, also is the soil fertility material base.
