Abstract
(l)本試驗為探討PCP尿素中含有之「PCP-Na」對於水田雜草之殺草效力及氮成分之硝酸化成抑制效力對水稻之生育，產量的影響，而在臺北、桃園兩地舉行田間試驗同時在實驗室內進行化驗分析。
(2)田間試驗結果PCP尿素對於水稻收量增產之影響較優於尿素，其原因可推定為「PCP-Na」之硝化抑制作用及殺草力之影響所致。
(3)PCP尿素之「PCP-Na」成分具有硝酸化成之抑制力同時對銨化作用有阻礙之傾向。
(4)PCP尿素施用過量時對農作物具有藥害作用，故其PCP-Na使用量每公頃10公斤左右較為適宜，在此範圍內水稻之生育初期雖受接觸藥害之影響，但至生育後期即可漸次恢復自然，不致影響稻谷產量。
(1) Field experiments were conducted at Taoyuan and Taipei areas to compare the fertilizer effect of PCP-urea with that of urea. The nitrification inhibitory effect of PCP-urea was also tested in the laboratory.
(2) With the same rate of nitrogen, PCP-urea gave a slightly higher grain yield than urea in the experiment, which might be attributed to both the nitrification inhibitory and the weed controlling effect of PCP-Na cantained in PCP-urea. migh be attributed.
(3) Nitrification is suppressed by PCP-urea, which is regarded favorable for the availability of nitrogenous fertilizer to the rice plant under water logged condition, as well as the ammonification of urea itself is also affected.
(4) Rice plants were injured by PCP-urea, however within the rate of 10 kg/ha, the plants were soon recovered.
