遵照毛主席“综合利用很重要”的教导,在厂党委的领导下,于一九七六年三月份成立了三结合试验小组,开始了变废为宝的战斗,进行了利用树皮废渣试制腐殖酸类肥料的试验。我厂生产栲胶每年用约六万吨落叶松树皮作为原料,这些树皮经过浸提之后成为废渣,除一部分掺合煤炭送往生产锅炉燃烧和用于居民烧火之外,多年来这些树皮废渣堆积成灾。大多数堆积在厂区周围,有时需要调动大量的运输力和劳力把堆积在厂区周围的树皮废渣运走,成为我厂生产中的老大难问题之一。 Following Chairman Mao’s “comprehensive utilization is very important” teaching, under the leadership of the factory party committee, in March 1976 set up a triple combination of experimental groups, began the fight for turning waste into treasure, the trial of the use of bark waste Humic acid fertilizer test. Our factory produces about 60,000 tons of larch bark per year as raw materials. After bark extraction, these barks become waste residue, except for part of the blended coal which is sent to the production boiler for burning and for residents to burn. Over the years these barks Slag accumulation disaster. Most of the accumulation in the plant area around, and sometimes need to mobilize a large number of transport capacity and labor to accumulate in the plant around the bark debris removal, become one of the most difficult problems in our plant production.
