| 中文摘要: |
| 用浓度为2、5、10、15、20mg/L的植物高效活性剂分别处理苗期和生长期的香根草，研究其对香根草生长的影响。结果表明：苗期或生长期用植物高效活性剂处理香根草，均可以促进香根草的生长；苗期处理的香根草的株高、分蘖数、生物量高于生长期处理，而生长期处理的香根草的净光合速率、蒸腾速率和水分利用效率整体上高于苗期处理。综合各方面因素，苗期用浓度为20 mg/L 的植物高效活性剂处理香根草效果最好。 |
| 英文摘要: |
| The effect of plant high active agent with concentrations of 2, 5, 10, 15, 20 mg/L on the growth of vetiver in seedling stage and growth period were studied. The results showed that the plant high active agent could promote the growth of vetiverboth in seedling stage and growth period. Treated at seedling stage had higher height and more tillers and biomass, treated at growth period had higher net photosynthetic rate, transpiration rate and WUE value. The result indicated that vetiver had the best growth when it was treated by 20 mg/L plant high active agent in seedling stage. |
