针对2007至2008年度不同气候条件下,在黑龙江垦区西部雨养农业区对不同熟期春小麦品种进行不同播期试验,以寻求年际变化。最佳播期与产量关系,为本区域春小麦生产提供依据。
According to different climatic conditions from 2007 to 2008, different sowing dates of spring wheat cultivars with different maturity were studied in rainfed farming areas in the west of Heilongjiang Reclamation Area to seek interannual variation. The relationship between the best sowing date and yield provides the basis for spring wheat production in this region.
