我们从75年以来,先后在本省鄂城、黄陂、潜江、嘉鱼、通山等县,以及我院实习农场等14个点上,对水稻、小麦、大麦、棉花、蔬菜等作物进行了腐肥肥效的田间试验和盆栽试验.试验的土壤有江汉平原冲积性土壤、长江沿岸滨湖地区冲积湖积性土壤、鄂中平缓丘陵黄土、鄂东南丘陵红黄土等8种类型土壤.供试的腐植酸铵(简称腐铵,下同)是用当地产的风化煤(腐植酸总量在24～30%之间),按100斤风化煤与12～15斤的碳铵混合,氨化7～10天而成.腐肥用量为100～200斤/亩.试验均是在与等量碳铵为对照的条件下进行的.现将有关腐铵的研究结果简报于下.
Since 75 years, we have carried out rice, wheat, barley, cotton, vegetables and other crops at 14 sites including Echeng, Huangpi, Qianjiang, Jiayu, Tongshan counties in our province and internship farms in our province successively Field experiment and pot experiment of fertilizing effect of fertilizers were carried out.The soil tested included alluvial soil of Jianghan Plain, alluvial lake soil of Binhu area along Yangtze River, moderate loess hilly of E land and red loess of southeast Hubei province for test Ammonium humic acid (hereinafter referred to as humic ammonium, the same below) is used locally produced weathered coal (humic acid total between 24 to 30%), according to 100 kg of weathered coal and 12 to 15 kg of ammonium bicarbonate mixed, ammoniated 7 to 10 days made of rotting fertilizer dosage of 100 ~ 200 kg / mu The test is in the same amount of ammonium bicarbonate as the control conditions are now about the results of the study of ammonium briefed below.
