基肥配施土壤改良物对西藏盐碱地黑青稞光合特性的影响
Effects of Base Fertilizer Combined with Soil Amendments on Photosynthetic Characteristics of Black Qingke in Saline-Alkali Land of Xizang
探究基肥配施土壤改良物质对盐碱环境下黑青稞光合性能的影响,是为了西藏黑青稞高产栽培提供理论依据,本研究对基肥配施不同土壤改良物(生物质炭、腐植酸、柠檬酸)处理下,黑青稞花后旗叶叶绿素含量和光合特性进行了研究。结果表明:与常规施肥(CK)相比,基肥配施不同土壤改良物处理下,能够不同程度地提高黑青稞花后旗叶的叶绿素含量、净光合速率、胞间CO2浓度、气孔导度和蒸腾速率,延长有效光合作用期,延缓叶片衰老。其中,以基肥配施生物质炭处理效果最佳,为盐碱地种植黑青稞提高光合特性具有理论指导作用。
In order to explore the effect of base fertilizer combined with soil amendment on photosynthetic performance of black Qingke under saline-alkali environment, and provide theoretical basis for high-yield cultivation of black Qingke in Xizang. In this study, the chlorophyll content and photosynthetic characteristics of flag leaves after anthesis of black Qingke were studied under the treatment of base fertilizer combined with different soil amendments (biochar, humic acid, citric acid). The results showed that compared with conventional fertilization (CK), the chlorophyll content, net photosynthetic rate, intercellular CO2 concentration, stomatal conductance and transpiration rate of flag leaves after anthesis of black Qingke could be improved to varying degrees under the treatment of base fertilizer combined with different soil amendments, and the effective photosynthesis period was prolonged and the leaf senescence was delayed. Among them, the treatment effect of base fertilizer combined with biochar was the best, which provided theoretical guidance for planting black Qingke in saline-alkali land to improve photosynthetic characteristics.
