ABSTRACT
Soybean is an increasingly important source for livestock feed, biofuel feedstock, and protein in human diets (Masuda et al., 2009a). Global soybean demand has increased in the past decades, and will continue to rise in the future (Masuda et al., 2009b). China has demonstrated a steady increase in its share of soybean consumption since the second half of 1985s; more than two-thirds of the country’s market depends on imports (Tuan et al., 2004; Masuda et al., 2012). Climate change is increasing the risk of food security. Slight changes in climate resources, particularly temperature and precipitation, can lead to remarkable effects to soybean (Ferreira et al., 2011; Calzadilla et al., 2014). Related studies have reported that global warming is beneficial to soybean planting in higher latitude, particularly in Northeast China (Xiao et al., 2007), but disadvantageous to the lower latitude (Hao et al., 2010).
