我国机电排灌每年都要消耗大量的能源,成为农业耗能大户。就电力排灌而言,电力排灌用电量占全国总用电量的5％,占农业用电量的44％,目前我国排灌机械效率低,能源浪费约为20％,据此计算我国机电排灌节能潜力为24～30亿度电。 China’s electromechanical irrigation and drainage every year to consume a lot of energy, a large agricultural energy consumption. In terms of electricity drainage and irrigation, the power consumption of electricity drainage and drainage accounts for 5% of the total electricity consumption in the country and accounts for 44% of the electricity consumption in agriculture. At present, the irrigation and drainage machinery in our country is inefficient and the energy consumption is about 20%. Based on this, Energy saving potential of 24 to 3 billion degrees of electricity.
