Correlation Analysis on the Yield and Its Factors of Winter Wheat in South Huang-Huai River
摘要
Abstract
[Objective] To study the influencing factors on the yield of winter wheat ( Triticum aestivum L. ) in South Huang-Huai River, and explore the relationships between wheat yield and its factors. [ Method] According to the preliminary test data during 2009 -2010, a correlation and path analysis was conducted on the yield and yield factors of winter wheat in South Huang-Huai River. [Result] All the three yield factors increased with the improving yield, but produced different effects on yield. Under certain level of yield, the correlation degree between yield factors and yield was 1000-grain weight (0.309 68) > number of grains (0.219 75) > number of productive ears (0.054 58) ; their influence on yield was 1 000-grain weight (0.703 05) > number of productive ears (0.613 19) > number of grains (0.469 10). [Conclusion] According to the ecological conditions of wheat production in South Huang-Huai River, the 1 000-grain weight should be improved, the number of productive ears should be kept stable and the potential of improving the grains number should be exploited.关键词
