腐植酸类肥料是近年发展起来的一种新型肥料,它是采用富含腐植酸的泥炭、风化煤或褐煤为原料采用不同生产方式,与氮、磷、钾、钠等营养元素复合而成的有机—无机配合肥料。我省自1974年开始试制,由土法或半机械化过渡到具有一定规模的机械化,肥料质量大为提高。1981年底,化工部对我省宜春县腐肥厂进行了定型鉴定,标志着腐肥产品已经商品化。目前,我省机械化生产腐肥的工厂已有五个,年产能力约三万余吨。如何使这一新型肥料,在农业生产中发挥更大的作用,笔者根据我省几年来的试验资料,结合外省经验,对腐肥的施用方法作一综合介绍。一、着重施于经济作物,提高经济效益。1975—1977年,我省各地对腐肥在各种作物上的
Humic acid fertilizer is a new kind of fertilizer developed in recent years. It is made of humic acid-rich peat, weathered coal or lignite as raw materials, and is made of different nitrogen, phosphorus, potassium, sodium and other nutrients Organic - inorganic compound fertilizer. Trial production in our province since 1974, from the indigenous or semi-mechanized transition to a certain level of mechanization, fertilizer quality greatly improved. The end of 1981, the Ministry of Chemical Industry Yichun County, Shaanxi Province, fertilizer factory stereotypes, marking the fertilizer products have been commercialized. At present, our province has five mechanized production of fertilizer factory, with an annual output capacity of about thirty thousand tons. How to make this new type of fertilizer, play a greater role in agricultural production, the author based on experimental data in our province over the years, combined with the experience of other provinces, the method of application of fertilizer for a comprehensive introduction. First, focus on the application of cash crops, improve economic efficiency. 1975-1977, throughout the province on the rot on a variety of crops
