在北京房山区潮土和褐土上设置田间试验 .结果表明 ,长效碳酸氢铵 (长效碳铵 )一次基施使冬小麦整个生育期间植株健壮 ,叶色浓绿 ,不脱肥 ,其生物学特性均优于基、追各半施用处理 ,最后增产7%～ 1 2 2 % .其原因是一次基施处理氮肥利用率比分次施用处理的提高 7 4%～ 1 8 6 % .长效碳铵是冬小麦区改革耕作制度一种省工、增产、增收的氮肥新品 .
A field experiment was conducted on the soil and cinnamon soil in Fangshan District of Beijing.The results showed that the long-acting ammonium bicarbonate (long-acting ammonium bicarbonate) could make the plants robust during the whole growth period, The characteristics were better than the base, chasing each half of the application treatment, and finally increase the yield of 7% to 122% .The reason is that a base application of nitrogen fertilizer utilization than the graded application treatment increased 74% to 186% Ammonium bicarbonate is a winter wheat reform farming system A province of labor, increase production, increase nitrogen fertilizer new products.
