Discussion of Suitable Index for Wheat Before Overwintering Based on Interval Sowing Test
Abstract：Based on interval sowing tests in 2006-2007 and 2007-2008 of winter wheat for type of Zhengmai 366, combined with the observational data, which was the same variety for operation and services of many years, the paper studied the accumulated temperature, wheat growing condition before overwintering, as well as yield structure by methods of correlation analysis and least significant difference. It was concluded that： before overwintering of winter wheat, there was strong correlation between growing conditions and accumulated temperature of different developing stages, meanwhile, three elements that composed the final yield had dependence relation with accumulated temperature of different developing stages and tiller number, as well as LAI to a certain extent. Discussed wheat indexes as suitable sowing date, sowing temperature, et al has important sense for analyzing climate warming adapting measures of agriculture.
