| Abstract: | Maize is one of the main grain crops in China. Three provinces of Northeast China are the main areas of planting spring maize. It is important for spring maize to study the relationship between key growth stages and critical temperature and to analyze the impacts of climate change on cultivated patterns. In this paper, daily time series of meteorological variables during the period 1961-2010 at 72 stations and growth stages of spring maize during the period 1981-2010 at 5 typical agro-meteorological station... |
