| 摘 要： | 在盆栽不同施肥水平条件下,肥料增效剂聚天冬氨酸对玉米苗期肥料吸收以及生长的影响进行比较研究。结果表明,施用聚天冬氨酸可以使玉米幼苗中叶绿素的含量增加,叶片中硝酸还原酶的活性增强,光合速率加快进而加速光合产物的积累,聚天冬氨酸有利于玉米干物重积累,尤其在养分较为充足条件下,单株地上部干重和总干重分别增加19%和16%。施用聚天冬氨酸有利于促进玉米幼苗对氮、钾的吸收,在养分较充足条件下,植株氮、钾吸收量分别增加27%和19%。

| Abstract: | The effect of polyaspartic acid on maize growth at seedling stage was studied in pot experiment and under different fertilizer applied condition. The results showed that polyaspartic acid indeed increased leaf chlorophyll content, leaf blade nitric acid reducted as activity and photosynthesis as well, which contributed to the increase of dry matter of seedling plant, especially under full fertilizer supply, the dry matter of shoot and total plant was increased by 19% and 16% respectively. Meanwhile, polyaspartic acid could enhance the uptake of nitrogen and potassium by plant root, and the nitrogen and potassium uptake was increased by 27% and 19% respectively under sufficient fertilizer supply condition. |
