摘  要:
由于农田生态系统过量施肥而产生的气候变化和氮肥利用率较低的问题日益严重,寻找改善土壤质量、减少温室气体排放以及增加作物产量的有效途径尤为重要.近年来,生物质炭在全球范围内被广泛应用于农业生态系统的固碳减排,而其对各类农田生态系统氮素转化以及作物产量的影响并不一致.本文选取生物质炭对南方典型的稻麦轮作系统以及菜地生态系统氮素利用率的影响进行比较,为进一步研究不同农业生态系统中生物质炭与氮肥、植株的互作关系以及合理利用提供理论依据.

摘  要:
Climate changes and low nitrogen use efficiency(NUE)are increasingly becoming the serious problems due to the excessive nitrogen fertilization application in agriculture ecosystems,so it is important to find an effective way to improve the soil quality,decrease the greenhouse gases(GHGs)and increase the crop yield.Recently,biochar has been used world widely to achieve the carbon sequestration in agriculture ecosystems,but the effects of biochar on nitrogen transformations and crop yield were not consistent with various agriculture ecosystems.Therefore,we compared the effects of biochar on the NUE of typical agriculture ecosystems in southern China,namely,rice-wheat annual rotation system and vegetable agriculture ecosystem to provide a theoretical basis for the interaction among biochar,nitrogen fertilization and plant in various agriculture ecosystems.
