| 摘 要： | 合理施氮量可促进生姜生长，提高叶片含氮量及叶绿素含量，增强光合作用速率，从而提高产量。但氮肥用量过多，可减少养分向根茎的分配率，而造成减产。本试验条件下施氮量以６００ ｋｇ·ｈｍ － ２ 为最佳，生姜产量达４５ ３３０ ｋｇ·ｈｍ － ２ ，分别比对照和施氮量１ ２００ ｋｇ·ｈｍ － ２ 处理增产６１ ．１ ％ 和２３ ．７ ％ 。

| Abstract: | Appropriate amount of nitrogen could increase the growth of ginger,the content of chlorophyll and nitrogen in ginger leaves,the photosythetic rate and the yield of ginger. Too much nitrogen could decrease the distribution of nutrition of rhizome and yield of ginger. The application of 600kg·hm -2 was best for the growth of ginger,and the yield reached 45330kg·hm -2 , which was 61.1% and 23.7% higher than that of control and 1200kg·hm -2 respectively. |
