| 英文摘要 | Application of biochar in farmland to increase crop yield is globally used in agriculture. However, the benefits of biochar applications for agricultural drought-resistant in wheat farmland have not yet been sufficiently studied. To close this research gap, water isotopes (H-2 and O-18) were used to explore the effect of biochar application in 0-20 cm soil on water use pattern of winter wheat (Triticum aestivum L.) at a shallow Entisol in the Southwest China. The results showed that isotopes of soil water (SW) with biochar addition were more enriched than the values of plots without biochar. Correspondingly, the stem water for winter wheat with biochar was also more enriched than the ones without biochar. Biochar significantly decreased the soil bulk density and increased SW content of the uppermost 0.1 m during wintering and filing stages. Winter wheat water uptake pattern correlated with its root distribution. Winter wheat absorbed more water (0.7-4.3%) from 0-0.2 m soil layer under biochar-amended treatment than the control experiment, but the differences were not significantly at the heading, filling and ripening stages. The mechanism was explained by that the amendment of biochar significantly improved the plant available water capacity because of increased storage pores (0.68-30 mu m). This is due to the biochar which was a porous media itself improves soil structure by forming aggregates and increasing pore connectivity and quantity in the soils. Therefore, biochar application showed to be beneficial method in agricultural water management for alleviating the effect of drought on crop growth. (C) 2020 Friends Science Publishers |
