在毛主席无产阶级革命路线指引下,我省农村社队以阶级斗争为纲,坚持党的基本路线,自力更生,艰苦奋斗,广泛开展土法生产腐植酸类肥料的活动。为此我们对土法生产中的一些技术问题进行了调查和总结,现介绍如下. 原料细度和风化问题为了使氨水与草炭充分反应,原料应晾干粉碎,并通过80～100目筛子,粒度最好小于0.26毫米。但是,土法生产有困难,从实际情况出发,粒度在1～5毫米也可。草炭打碎后.立即拌氨熟化,效果较差。因此,草炭挖出后,应经过一段时间风吹日晒.一方面风干便于粉碎和拌氨水,另一方面可使 Guided by Chairman Mao’s proletarian revolutionary line, the rural communes and communes in our province, taking the class struggle as the key link, upholding the party’s basic line, relying on their own efforts and working hard to carry out extensive activities for the production of humic acid-type fertilizers by indigenous law. To this end, we conducted a survey and summary of some technical problems in indigenous production and are presented below: Raw Material Fineness and Weathering In order to fully react ammonia and peat, the raw materials should be dried and crushed and passed through 80-100 mesh sieves, The grain size is preferably less than 0.26 mm. However, indigenous production difficulties, starting from the actual situation, the particle size of 1 to 5 mm can be. Peat smash immediately after mixing ammonia aging, the effect is poor. Therefore, after digging out of the peat, it should be exposed to the wind and wind for some time.On the one hand, it is easy to crush and mix the ammonia by air-drying, on the other hand
