摘  要：
脲铵氮肥是新近研制的复合氮肥。研究表明,脲铵氮肥用于小麦全期追肥在碱性潮土上的肥效显著好于氯化铵、尿素和碳酸氢铵,N当季吸收率达77.19%,N的当季吸收量和吸收率比氯化铵分别增24.9 kg/hm2和13.26个百分点。比尿素分别增加43.05 kg/hm2、22.98个百分点。比碳酸氢铵分别增加80.7 kg/hm2、43.02个百分点。酸性水稻土上的N吸收量和吸收率比氯化铵分别减少14.25 kg/hm2、7.58个百分点。比尿素分别增加6.15kg/hm2、3.32个百分点。比碳酸氢铵分别增加31.8 kg/hm2、16.98个百分点。在碱性潮土上的小麦平均产量8134.2 kg/hm2,极显著地高于碳酸氢铵和尿素。与单施粉状氯化铵相比虽有增产,但增产差数未达显著。在酸性水稻土上小麦产量虽比尿素、碳酸氢铵增产,但增产差数也不显著。

摘  要：
Urea-ammonium chloride is a new kind of nitrogen fertilizer.In this study it was used as a top dressing and compared with ammonium chloride,urea,and ammonium bicarbonate.The results showed that the Absorption rate of urea-ammoniumchloride was 77.19%,and in current crop seasons on alkaline Fluvo-aquic soils it was 13.26,22.98,and 43.02 percentage point significantly higher than ammonium chloride,urea,and ammonium bicarbonate,respectively.The Absorption amount was 24.9 kg·hm-2,43.05 kg·hm-2,and 80.7 kg·hm-2 significantly higher than the latter three,respectively.Wheat yield was 8134.2 kg·hm-2 and significantly higher than urea and ammonium bicarbonate,respectively,but not significantly higher than powder ammonium chloride.In acidic paddy soils the Absorption rate of urea-ammonium chloride was 3.32 and 16.98 percentage point higher than urea and ammonium bicarbonate,respectively,but 7.58 percentage point less than ammonium chloride.Absorption of urea-ammonium chloride was 6.15 kg·hm-2 and 31.8 kg·hm-2 higher than urea and ammonium bicarbonate,respectively,but 14.25 kg·hm-2 less than ammonium chloride.Wheat yield was higher than urea and ammonium bicarbonate,but the difference was not significant.
