| 摘 要： | 以黑土为供试土壤,根茎为繁殖材料,分别测定了不同生长时期内穿龙薯蓣全株氮、磷、钾养分含量并分析其变化规律。结果表明:在长春地区,生长季内氮、磷、钾的吸收量N:P2O5:K2O=5.8:1:5.3。氮、钾在5月30日~7月10日是第一个吸收高峰期,7月10日达全年最大值,磷则在5月30日~7月21日,7月21日达全年最大值;氮、磷、钾在8月12日~9月1日时均出现了第二个吸收高峰期,在9月1日同时达到第二个吸收峰值。 |

| Abstract: | Black soil was used as the experiment soil and plant root and stem were used as propagate materials.The content of nitrogen,phosphorus and potassium of Dioscorea nipponica Makino in different growth periods was measured.The result showed that the absorbed quantity of nitrogen,phosphorus and potassium in growth period was N∶P_2O_5∶K_2O= 5.8∶1∶5.3 in Changchun area.The first peak for nitrogen and potassium appeared in the period of May 30 to Jul.10,but the absorbed phosphorus appeared in the period of May 30 to Jul.21,the second absorbed peak for all three nutrients appeared in the period of Aug 12 to Sep.1. |
