为了探讨腐铵在红壤上施用的增产改土效果、特别是施用腐铵后土壤理化性质的变化,我们从1976年开始,先后在新垦的红壤旱地和水田进行对比试验,所得结果,曾有过报导。去年根据全国腐植酸会议的精神,再次分别在新垦红壤旱地和水田,用腐铵,原料煤和等氮量碳铵进行对比试验,以进一步验证原来的试验结果,并着重比较原料煤与腐铵之间的差异。现将试验的基本情况和结果报导如下:
In order to investigate the effect of applying ammonium fertilizer on soil improvement and yield improvement of red soil, especially the change of soil physical and chemical properties after application of ammonium nitrate, we started from 1976 and conducted comparative experiments on newly cultivated red soil dry land and paddy field. Reported. Last year, according to the national meeting of humic acid, again in the red soil reclamation dryland and paddy fields, respectively, with ammonium, raw coal and ammonium nitrogen to compare the amount of ammonium in order to further verify the original test results, and focus on the comparison of raw coal and rot Differences between ammonium. Now test the basic situation and the results reported as follows:
