我们忻县化工厂在生产糠醛的同时,每天排出20-30吨糠醛废渣。过去,这些渣子都是作为廉价燃料处理的。1973年以来,根据县委的指示,我们大搞综合利用,开展了醛渣(玉米芯作糠醛的醛渣)作肥料的试验。在我县广大贫下中农的支持下,取得了良好的效果。事实表明:醛渣肥料对作物有明显的增产效果,它能促使土壤变成保土、保水、保肥的大寨式海绵田,从而提高土壤肥力,对改良盐碱地尤
We Xinxian chemical plant in the production of furfural, 20-30 tons of furfural waste discharged daily. In the past, these dregs were treated as cheap fuel. Since 1973, according to the instruction of the county committee, we have made great efforts in the comprehensive utilization and carried out the experiment of aldehyde slag (aldehyde slag with corn cob as furfuraldehyde) as fertilizer. With the support of the majority of poor and middle peasants in our county, good results have been achieved. The facts show that the aldehyde slag fertilizer has obvious yield increasing effect on the crops, and it can make the soil become a Dazhai type sponge field which is soil-keeping, water-holding and fat-keeping so as to improve the soil fertility.
