Abstract

Adapting agriculture to climate change is essential for sustainable food production. However, the development of suitable adaptation mechanisms requires a clear understanding of the plant-climate interaction. The number of growing degree days (GDD) is a good proxy for understanding plant-climate interrelationship and farm productivity. Here, using a 2-year experiment of barley-sweet corn double cropping (DC) system and 20-year climate and yield data, we found that barley and sweet corn GDD and productivity were strongly related to changes in climate patterns. Furthermore, we found a positive effect of the barley-sweet corn DC system on farm productivity (18.5 and 5.6 tonnes. ha−1 for DC and single cropping respectively) and return on investment (1.8; 1.4 as benefit:cost ratios for DC and single cropping system respectively). Altogether the results of this study suggest that the winter barley-sweet corn double cropping system is a potential strategy to boost farm productivity as well as an adaptation mechanism to be considered for the changing climate in the study region.

喀尔巴阡盆地对气候变化模式的双重种植适应机制

使农业适应气候变化对可持续粮食生产至关重要。然而，建立合适的适应机制需要对植物与气候的相互作用有一个清晰的认识。生长度日数(GDD)是了解植物-气候相互关系和农业生产力的一个很好的指标。利用2年的大麦-甜玉米双季制试验和20年的气候和产量数据，我们发现大麦和甜玉米的gdp和生产力与气候模式的变化密切相关。此外，我们发现大麦-甜玉米直流系统对农场生产力(18.5和5.6吨)有积极影响。直作和单作分别为ha−1)和投资回报率(1.8;1.4为效益:分别为直作和单作的成本比)。综上所述，本研究结果表明，冬大麦-甜玉米双熟制度是提高农业生产力的潜在策略，也是研究区域气候变化的一种适应机制。
