最近,农林部邀请了山东省土壤肥料研究所、华北农业大学、中国农林科学院原子能利用研究所、中国科学院南京土壤研究所等十七个单位,对于腐植酸类肥料的肥效和经济效果进行了座谈总结,写出了《三年来腐植酸类肥料肥效试验情况的报告》。试验表明,腐植酸类肥料只要质量保证,施用在有机质缺乏的瘠薄低产土壤和中等肥力土壤,以腐植酸铵为例,亩施量二百斤至三百斤,作水稻、小麦、玉米、高粱等粮食作物基肥或制成球肥深施,一般平均每斤腐肥增产粮食半斤左右,对油菜、蔬菜等其他作物也有增产效果。腐肥,可同农家肥料堆沤或直接施用;推广腐肥施用,可充分利用本地泥炭、褐煤、风化煤等资源,为增加土壤有机质、培肥地力、改良低产田,提高粮、油产量开辟了新的途径。为便于我省各地学习、推广、利用腐肥,我们把农林部转发的《三年来腐植酸类肥料肥效试验情况的报告》刊载这里,供参考。——编者
Recently, the Ministry of Agriculture and Forestry invited 17 institutes including Soil and Fertilizer Institute of Shandong Province, North China Agricultural University, Atomic Energy Utilization Institute of Chinese Academy of Agriculture and Forestry, and Nanjing Institute of Soil Science, Chinese Academy of Sciences to discuss the fertilizer efficiency and economic effect of humic acid fertilizers To sum up, write “three years report of humic acid fertilizer fertilizer efficiency test.” The results showed that the humic acid fertilizers could be applied in the infertile soils and medium fertility soils lacking in organic matter. Taking humic acid ammonium as an example, the humic acid fertilizers applied from two hundred to three hundred catties as rice, wheat, corn and sorghum Other grain-based crops such as fertilizer or made of deep-fat facilities, the average yield per kilogram of fertilizer per kilogram of about half a catty, on rapeseed, vegetables and other crops also increase yield. Rot manure can be used in combination with peasant manure or applied directly. Popularization of manure application can make full use of local peat, lignite, weathered coal and other resources to open up soil organic matter, fertility and fertility, improve low-yield fields and increase grain and oil production A new way. In order to facilitate the study, promotion and utilization of manure in our province, the “Report on Fertilizer Efficiency Test of Humic Acid Fertilizers in Three Years”, which is forwarded by the Ministry of Agriculture and Forestry, is here for reference. --editor
