| 摘 要： | 研究了Ｎ、Ｐ、Ｋ施用水平对生姜光合特性和ＮＰＫ吸收的影响。结果表明：中水平处理（每６６７ｍ２施Ｎ４０ｋｇ、Ｐ２Ｏ５７．５ｋｇ，Ｋ２Ｏ４０ｋｇ）叶片叶绿素含量高，光合和蒸腾强，对ＮＰＫ吸收多；低水平（Ｎ３Ｐ７．５Ｋ４０，Ｎ４０Ｐ０Ｋ４０，Ｎ４０Ｐ７．５Ｋ０）和高水平（Ｎ８０Ｐ７．５Ｋ４０，Ｎ４０Ｐ１５Ｋ４０，Ｎ４０Ｐ７．５Ｋ８０）施肥处理，上述指标均有不同程度的降低。

| Abstract: | The effects of different levels of supplying nitrogen,phosphorus,potassium on photosynthesis characteristics and NPK absorption were studied in gingers. The results indicated that for the middle level treatment (N 40kg,P 2O 5 7.5kg,K 2O 40kg per 667m 2) the leaves had higher chlorophyll content,strong photosynthesis,transpiration and more amount of the absorption of NPK. These objectives all decreased in some degrees for the low treatments (N 3P 7.5 K 40 ,N 40 P 0K 40 ,N 40 P 7.5 K 0) and high treatments (N 80 P 7.5 K 40 ,N 40 P 15 K 40 ,N 40 P 7.5 K 80 ). |
