通过2009~2010年在春小麦上进行多点分散的“3414”试验,通过一系列相关性分析出春小麦养分丰缺指标及不同养分丰缺指标等级下的推荐最佳施肥量范围,计算出春小麦单位经济产量吸收养分量、肥料利用率、土壤养分校正系数等参数,为施肥指导提供科学依据。
Through a series of correlation analysis, the index of spring wheat nutrient abundance and deficiency and the recommended optimum fertilization range under different nutrient abundance and deficiency index grades were calculated by using “34014” Spring wheat yield per unit of economic yield, fertilizer utilization, soil nutrient correction coefficient and other parameters provide a scientific basis for fertilization guidance.
