| 摘 要： | 研究新型腐植酸有机液肥对植物抗旱性的调节作用。通过分析喷施2次新型腐植酸有机液肥后4种类型植物的蒸腾速率和净光合速率抗旱生理指标的变化,对新型腐植酸有机液肥在提高植物抗旱性方面的作用进行评价。供试植物喷施2次新型腐植酸有机液肥后水分利用率较清水对照上升7.60%～34.32%,较喷施1次后水分利用率上升幅度有所增加,上升幅度增加值为0.69%～15.60%。喷施新型腐植酸有机液肥能显著降低植物的蒸腾速率和提高净光合速率,从而提高不同植物的水分利用率,增强其抗旱性。

| Abstract: | The regulating effect of a new humic acid organic liquid fertilizer on plant drought-resistance was evaluated through the changes of transpiration rate and net photosynthetic rate of four plants after sprayed the new humic acid organic liquid fertilizer.The results showed that the water use efficiency of plant was increased by 7.60%～34.32% in treatment with sprayed the new organic liquid fertilizer twice than that in control,and was increased by 0.69%～15.60% than that in the treatment with sprayed once.Applying the new organic liquid fertilizer could obviously improve water use efficiency of plant through reducing transpiration rate and enhancing net photosynthetic rate. |
