人尿为良好之速效氮肥,田间试验结果,巳于前篇讨论,惟因储存上之困难,仍难充分利用。察人尿中尿素,在普通贮存情况下,迅速水解为碳酸铵,再分解为氨与二氧化碳,氨则飞散丢失,故尿之储存问题,即是氮的保存问题。今将初步试验结果,讨论如下:一、人尿贮存氮素丢失情形,二、人尿与土或麦捍发酵,对于氮素之保特,三、土壤吸收铵的性能,四、钾、钠游子对于土壤吸收铵根之影响。
Human urine is considered to be a good quick-acting nitrogen fertilizer. The results of the field trial have been discussed in the previous section, but are still not fully utilized due to storage difficulties. Personnel urine urea, in the case of ordinary storage, rapid hydrolysis of ammonium carbonate, and then broken down into ammonia and carbon dioxide, ammonia is scattered lost, so the storage of urine, that is, the issue of nitrogen preservation. The preliminary test results will be discussed as follows: First, the loss of nitrogen stored in human urine, human urine and soil or Mai Han defeated fermentation, for the special security of nitrogen, three, soil absorption of ammonium performance, potassium, sodium Effect of wanzi on ammonium absorption by soil.
