Title: | 2-Amino-4-chloro-6-methylpyrimidine抑制氮肥硝酸化作用之研究(第1報) | Other Titles: | A Study on 2-Amino-4-Chloro-6-Methyl Pyrimidine as a Nitrification Inhibitor in Paddy | Authors: | 溫西濱 H.P. Wen |
Issue Date: | 8-Mar-1967 | Publisher: | 農業試驗所 | Journal Volume: | 16 | Journal Issue: | 1 | Start page/Pages: | 76-83 | Source: | 農業研究 | Abstract: | 本試驗之目的為探討2-Amino-4-chloro-6-methylpyrimidine(簡稱AM)之施用對于水稻產量之影響,及對土壤中硝酸化作用之抑制效果,於1966年間採用直播栽培法舉行水稻盆栽試驗,並在實驗室內分析土壤中之NH3-N和NO3-N生成量,以究明所施尿素之銨化及硝酸化情形,測定AM之硝酸化抑制效果。 據盆栽試驗結果AM之施用對于稻谷之增收確有效果,土壤實驗結果示AM對尿素之銨化作用並無影響,但對其硝酸化卻有顯然抑制效果。 由以上結果可以推知AM在容易發生脫氮作用之環境下(如輪流灌溉地區或缺水地區水稻直播栽培)對于氮素肥料肥效之增進將有裨益。但實際應用效果如何尚待繼續試驗。 To test the effect of 2-Amino-4-chloro-6-methyl pyrimidine (A.M.) as a nitrifica-tion inhibitor in soil and its applicability in rice culture, a pot experiment under which loss of nitrogen by percolation and denitrification prevailed was conducted. A. M. was observed not to affect the rate of ammonification of urea, whereas the nitricfication was significantly suppressed by A. M. and the availability of the fertilizer applied for the plant was highly improved by its application. It is predicted that A.M. may be quite advantageous for certain paddy fields or cultivation methods under which denitrification is inevitable. |
