2005年国家测土配方施肥资金补贴项目开始在河南省洛阳市各县陆续实施,2009年该项目在本市实现了全覆盖。项目实施以来,全市进行了大量的夏玉米田间试验。通过对70个丰缺指标试验和97个“3414”试验中的丰缺指标处理设计等结果进行分析,探索了夏玉米生育期的平均土壤养分校正系数、土壤供肥能力、100 kg籽粒吸收养分量、肥料利用率、最大最佳施肥量等区域技术指标,确定了洛阳市
In 2005, the national soil testing and formula fertilizer subsidy project started to be implemented successively in all counties in Luoyang, Henan Province. In 2009, the project achieved full coverage in this Municipality. Since the implementation of the project, the city conducted a large number of summer maize field trials. By analyzing the results of 70 indices of abundance and deficiency index and 97 indices of “3414”, the average soil nutrient correction coefficient of summer maize, soil fertility, soil fertility, Absorption of nutrients, fertilizer utilization, the maximum and optimum fertilization and other regional technical indicators to determine the Luoyang City
