朝阳地区每年播种谷子200万亩左右,占粮食作物总面积的40～50％。由于品种杂乱、退化严重,种植密度低,施肥不足,管理粗放和发病较重等原因,一般亩产只有二、三百斤。要扭转谷子的低产局面,必须从以下几方面着手。1.选用良种1982、1983两年,我们对朝阳地区引进和推广的8个谷子品种进行了多点产量对比试验。产量最高的
In the Chaoyang area, about 2 million mu of sown millet are annually planted, accounting for 40% to 50% of the total area of food crops. Due to the chaotic species, serious degradation, low planting density, insufficient fertilization, extensive management and heavy incidence and other reasons, generally only two or three hundred jin per mu. To reverse the millet low-yield situation, we must start from the following aspects. 1. Selection of elite 1982,1983 two years, we introduced and popularized the eight millet varieties in Chaoyang area for more yield comparison test. The highest output
