定向爆破搬山造田是大寨贫下中农大干社会主义,为农业机械化创造条件的雄伟壮举。他们发扬自力更生、艰苦奋斗的精神,自已制造了铵油炸药。这种炸药由硝酸铵、柴油、锯木粉混合而成,成本低,原料来源广,适合当地自己加工。但是硝酸铵是化肥,柴油是农业机械的燃料,农田基本建设搬山造田使用大量铵油炸药就要占用一定数量的化肥和柴油,能否研制出价格更低廉、原料来源更广泛、效果更良好的土炸药,成为广大贫下中农的迫切要求。 Directional blasting and removal of land are the magnificent feats of creating conditions for agricultural mechanization in Dazhai. They carried forward the spirit of self-reliance and hard work and manufactured their own ammonium explosives. The explosives from ammonium nitrate, diesel, sawdust mixed, low cost, wide source of raw materials for local processing their own. However, ammonium nitrate is a fertilizer. Diesel oil is a fuel for agricultural machinery. The use of a large amount of ammonium-based explosives in farmland capital construction has a certain amount of fertilizer and diesel oil to be occupied. Can we develop cheaper prices, more extensive sources of raw materials and better results? Of the soil explosives, become the urgent need of the majority of poor and middle peasants.
