摘要
试验测定碳酸氢铵、硝酸铵和尿素三种氮肥在150、300、450、600、750 kg/hm25个不同用量水平对潍县萝卜叶面积的影响。结果表明:碳酸氢铵的促叶效果最好,其次为硝酸铵,尿素的促叶效果较差。
The leaf areas of Weixian radish were measured at the nitrogen supply levels of 150,300,450,600,750 kg/hm2 of ammonium bicarbonate,ammonium nitrate and urea respectively.The results showed that ammonium bicarbonate had the best leaf-area increasing effect,which was followed by ammonium nitrate and urea in turn.
