Research of Precision Sowing Date of Winter Wheat ( Triticum aestivum ) in the Region along Huaihe River in Anhui Province in Dealing with the Climate Change
摘要
Abstract
[Objective] The purpose was to confirm the precise sowing date of winter wheat in the region along Huaihe River in Anhui Province. [ Method ] The predictability of the precise sowing date of winter wheat in the region along Huaihe River in Anhui province was studied according to the high-yielding cultural techniques of winter wheat and the meteorological data. [Result] The results showed that the suitable sowing dates had a delay trend in this region, the change rate was about 1. 75 d every 10 years, and climate warming was the fundamental cause of the delaying. But the sowing dates were fluctuations in the past 61 years, and the irregular extreme weather conditions were the main cause. The precise sowing date was potential predictability based on the regularly downward trend and after-effect of temperature. The research showed that the index of sowing date in the region along Huaihe River in Anhui Province was the first day when the five days moving average temperature below 17 ℃ , and then the precision sowing date could be accurately predicted based on the accurate routine weather forecast. [ Conclusion] The study provides a reference for high yield and good quality cultivation of winter wheat in the region along Huaihe River in Anhui Province.关键词
