一讨论这个问题的重要意义石油是一种世界性能源,又是重要的战略物资,在现代各国的能源中占重要位置。现代农业的能源,一是靠太阳能,二是靠矿物能。随着农业现代化程度的提高,所需要的能源量相应增大。如美国,从1954～1970年,每公顷耕地消耗电力增加9倍,而消耗燃油增加5倍,日本自1950～1974年,每公顷耕地消耗电力增加1倍,而消耗燃油增加20倍。根据我国石油资源及开采情况和我国的能源政策,石油产量在相当长的时期内不可能有所增长。在这种情况下,农用柴油的供
A discussion of the significance of this issue Oil is a global energy, but also an important strategic material, in the modern energy occupy an important position. The energy of modern agriculture, one by the solar energy, the second is by minerals. As the level of agricultural modernization increases, the amount of energy required will increase correspondingly. For example, in the United States, from 1954 to 1970, the power consumption per hectare of cultivated land increased ninefold while the consumption of fuel increased fivefold. Japan from 1950 to 1974 doubled the power consumption per hectare of arable land while consuming 20 times more fuel. According to China’s petroleum resources and mining conditions and China’s energy policy, oil production can not be increased for a long period of time. In this case, the supply of agricultural diesel oil
