Abstract:

The aim is to provide technical support for drought-resistant cultivation of oats. ‘Hebei-Zhangjiakou No.5’ oat was used as the test material in a pot experiment, the effects of fulvic acid and S-abscisic acid (S-ABA) on the photosynthesis characteristics and yield of the variety in different periods and under different water supply conditions under drought stress were analyzed. The results showed that both fulvic acid and S-ABA improved the photosynthesis characteristics and yield of ‘Hebei-Zhangjiakou No.5’ to varying degrees. Under normal water supply, moderate moisture stress and severe drought stress, the yield of oat under S-ABA treatment was increased by 27.04%, 25.65% and 37.11%, respectively, compared with that of the control group, and the effect was better than spraying fulvic acid. Taken together, S-ABA has a significant influence on the increase of oat yield.
