摘要
An optimal temperature and sunshine hours (T&S) condition will contribute significantly to increase rice yield and nitrogen use efficiency (NUE). The T&S condition of a location serves as a limiting factor for NUE. The results of this study indicated that higher NUE and grain yield of rice could be obtained with the combination of higher effective active temperature and fewer sunshine hours during the entire growth period in Northeast China. The T&S conditions in the southern region of Northeast China promoted rice growth, and these conditions affected the assessment of local rice yield.
