一、我省生态条件与小麦的品质我省位于祖国的东北端,地处高纬度,属雨养农业生态区。虽然春旱夏涝为不利生态因素,但其土质肥沃,光照充沛,热量有余,昼夜温差大,利于干物质积累,适于春小麦生产。因此,从历史上看本区盛产小麦,而且以优质麦享誉国内外(见表1、2)。 First, the province’s ecological conditions and the quality of wheat Our province is located in the northeast end of the motherland, is located in high latitudes, is a rain-fed agricultural ecological zone. Although drought and summer flood are unfavorable ecological factors, its fertile soil, plenty of light and more calories, large temperature difference between day and night, is conducive to the accumulation of dry matter, suitable for spring wheat production. Therefore, historically, the region is rich in wheat and is renowned both domestically and internationally for its high-quality wheat (see Table 1 and Table 2).
