Study On Zonal Ecological Divergence And Technological Regulation And Control Of Winter Wheat Qulity

This experiment choose separately high-quality strains which comes from four wheat zone of our country and four wheat zone of Shanxi, did multidrop tests seperatly during the same year in the four wheat zone of China and Shanxi. The paper studied the zonal ecological divergence and strain divergence of quality characters of wheat; Moreover explored parts of the splendid technology of winter wheat from the perspective of soil nourishment and cultivation measures. The result showed: The quality characters of wheat was influenced by the strain genotype, ecological environment and various cultivation measures. In our country , protein content ,one of the main quality characters,presented the tendency of Northern Winter Wheat Zone >Yellow and Huai Valley's Facultative Wheat Zone >Lower Yangtze Valley's Wheat Zone >Middle and Higher Yangtze Valley's Wheat Zone, but the divergence was obviously related to the sunshine and rainfall of wheat's later stage (positive correlation to sunshine and negative correlation to rainfall),The correlation to accumulated heat was not marked ; Protein content , Ash content , Development time and mixing tolerance varied greatly according to the environmental effect in the several main quality characters. In Shanxi province , protein content varied greatly according to zonal ecological , but sedinmention value and gluten varied less; while taking a sweeping view of Shanxi, strain (Genotype) was most important for high-quality production; also indicated , There were strain resources and environmental resources of high-quality production of wheat in Shanxi , three main targets that represent the quality characters of wheat attained or surpassed the international standard, Shanxi wheat zone accorded with the nationwide quality division proposal, Yet sedimention value was the main contradiction that affects the Shanxi's proceeding quality of wheat. The research still showed that it was the significant practice of high production and high quality of wheat to apply fertilizer , The NP actes could effectively lift the yield of wheat and improve the quality of wheat; Deferring top-dressing time could improve the quality of wheat obviously. The research still saw, on the loess plateau lime earth , three elements of fertilizer dominated different action to the yield and quality in the different phase. The quality of dry land wheat was obviously better than that of irrigated land. Feeble light in later stage, spraying leaf hormone and manure during grian-filling stage obviously improved the quality of wheat. That the spike germinates was able to effect the quality of wheat seriously.
