“…APSIM rice-wheat rotation system model consists of two sub-models: APSIM-oryza model and APSIM-wheat model, which can simulate flooding condition for rice growth and drought conditions for wheat growth. APSIM model has been widely applied to simulate agricultural system in different regions of the world, including China (e.g., Wang et al 2012;Liu et al 2013;Xiao and Tao 2014).…”

Using the detailed field experiment data from 1981 to 2009 at four representative agro-meteorological experiment stations in China, along with the Agricultural Production System Simulator (APSIM) rice-wheat model, we evaluated the impact of sowing/transplanting date on phenology and yield of rice-wheat rotation system (RWRS). We also disentangled the contributions of climate change, modern cultivars, sowing/ transplanting density and fertilization management, as well as changes in each climate variables, to yield change in RWRS, in the past three decades. We found that change in sowing/transplanting date did not significantly affect rice and wheat yield in RWRS, although alleviated the negative impact of climate change to some extent. From 1981 to 2009, climate change jointly caused rice and wheat yield change by −17.4 to 1.5 %, of which increase in temperature reduced yield by 0.0-5.8 % and decrease in solar radiation reduced it by 1.5-8.7 %. Cultivars renewal, modern sowing/transplanting density and fertilization management contributed to yield change by 14.4-27.2, −4.7-−0.1 and 2.3-22.2 %, respectively. Our findings highlight that modern cultivars and agronomic management compensated the negative impacts of climate change and played key roles in yield increase in the past three decades.

“…In spite of this, adaptation measures such as cultivar shifts and management improvements could reduce the negative effects of warming climate on crop production (Liu et al 2010;Olesen et al 2011;Wang et al 2012). For example, the adoption of cultivars with longer growth periods could increase yield under climate change due to higher heat accumulation (Wang et al 2012;Liu et al 2013;Xiao and Tao 2014).…”

“…For example, the adoption of cultivars with longer growth periods could increase yield under climate change due to higher heat accumulation (Wang et al 2012;Liu et al 2013;Xiao and Tao 2014). Crop phenological processes are driven by the combined effects of climate variability and agronomic factors such as cultivar shifts and management practices, which are to some extent controlled by man (Liu et al 2010;Xiao and Tao 2014).…”

As climate change could significantly influence crop phenology and subsequent crop yield, adaptation is a critical mitigation process of the vulnerability of crop growth and production to climate change. Thus, to ensure crop production and food security, there is the need for research on the natural (shifts in crop growth periods) and artificial (shifts in crop cultivars) modes of crop adaptation to climate change. In this study, field observations in 18 stations in North China Plain ( ). The study suggests a gradual adaptation of maize production process to ongoing climate change in NCP via shifts in high thermal cultivars and phenological processes. It is concluded that cultivation of maize cultivars with longer growth periods and higher thermal requirements could mitigate the negative effects of warming climate on crop production and food security in the NCP study area and beyond.

“…There are seven provinces (cities) involved in this area 1 where summer maize is traditionally sowed one week before or directly after the harvesting of winter wheat depending on meteorological conditions at different locations within NCP. Annual regional grain yield (winter wheat plus summer maize) ranges from 11-13 t/ha 2,3 with a tendency of a tremendous yield increase since the 1960s but relatively stable yield after mid-1990s in NCP 4 . According to the results of modelling, potential yield of winter wheat can reach 9.75 t/ha 5 , and 13-15 t/ha for summer maize 6 .…”

ABSTRACT:Winter wheat (Triticum aestivum)/summer maize (Zea mays) rotation is a major system in the North China Plain. The wheat yield target was achieved recently, whereas the maize yield has been static since the 2000s, even with high density planting and fertilizer input. This study analyses the factors limiting maize growth and yield. Maize yields from eight field trials (2006)(2007)(2008)(2009)(2010)(2011) were classified into five levels: low yield (< 8.25), farmer yield (8.25-9.75), experimental yield (9.75-11.25), record high yield (11.25-12.75), and target yield (> 12.75) t/ha. Shoot dry weight, nitrogen accumulation, and leaf area index at critical stages, yield, and yield components were measured. Grain yield fluctuated from 6.4-13.8 t/ha (10.1 t/ha on average). Insufficient kernel number per ear and low kernel weight limited further yield improvement. Shoot dry weight, leaf area index, and shoot N-accumulation before silking did not vary among the different yield levels, whereas after silking these parameters were significant larger at high yield levels. It can be concluded that low kernel number per ear across yield levels was related to source limitation pre-silking. Additionally, low kernel weight was due to poor post-silking dry matter production. However, the potential of yield increment through increasing source size was limited under the current system. Strategies to enhance post-silking leaf and root function shall therefore be considered to improve post-silking dry matter production and transportation under a high density and high nitrogen input system.
