中文摘要 | 本文由耕耘機、曳引機、單位率地面積馬力數及主要作物平均總產量的變遷來探討臺灣機耕發展的趨勢。分析1960到1980年20年的資料,指出本省機耕動力逐漸朝向曳引機的推廣使用,與農機發展進步國家比較,本省機率動力成長速率甚快,極具發展潛力。主要作物平均總產量與單位率地面積馬力數之間有顯著迴歸關係。 |
英文摘要 | The development and extension of power tiller and tractor in Taiwan from 1960 to 1980 were studied in this paper. During the past twenty years, Taiwan’s power tiller has increased from 3,700 units to 65,000 units, wheel tractor from 500 nits to 3,700 units, the available power of tractors and power tillers per hectare of arable land and land under permanent crops from 0.005 hp/ha to 1.04 hp/ha, the average aggregate yield of major crops from 3,000 kg/ha to 4,400 kg/ha, and the farm land from 870,000 ha to 910,000 ha. The annual growth rates of available input power of tractors and tillers were 0.015 hp/ha-yr in 1960-65, 0040 hp/ha-yr in 1965-74, and 0096 hp/ha-yr in 1974-80. The straight line log type regression equation between the yield of various crops and power used per hectare in Taiwan was established with a significant coefficient of correlation of 0.8896. It is estimated that the input power per hectare of farm land in Taiwan will reach 2.5 hp/ha before 1990. A comparison among Taiwan, Japan, U.S.A., U.K., and Israel on major crops yields in kg/ha and available powering hp/ha was also investigated in this paper. At the present time, the respective available horsepower and the average aggregate yield of major crops per hectare of arable land and land under permanent crops is 1.04 hp/ha and 4,400 kg/ha in Taiwan, 7.86 hp/ha and 7,200 kg/ha in Japan, 3.36 hp/ha and 6,200 kg/ha in Israel, 3.12 hp/ha and 5,800 kg/ha in U.K. and 1.32 hp/ha and 4,700 kg/ha in U.S.A.. |
