开展测土配方施肥田间试验是获得各种作物最佳施肥量、施肥比例、施肥时期、施肥方法的根本途径,也是筛选、验证土壤养分测试方法、建立施肥指标体系的基本环节。只有做好田间试验,获得真实有效的数据,使田间试验结果准确可靠,符合客观实际,才能真正在农业生产中得到应用。在田间试验实施过程中,从试验地的选择、备耕、播种、施肥、田间管理、观察与记载,一直到收获,试验结果产量分析,都存在着应该注意的问题。结合实际工
Carrying out the soil testing and formulating fertilization field experiment is the fundamental way to get the optimum fertilization amount, fertilization proportion, fertilization period and fertilization method for all kinds of crops. It is also the basic link of screening and verifying the soil nutrient testing method and establishing fertilization index system. Only by doing field experiments and obtaining real and effective data can make the field test results accurate and reliable and accord with the objective reality, can we really get the application in agricultural production. In the process of field experiment, there are some problems that should be noticed from the selection of test sites, preparation for cultivation, sowing, fertilization, field management, observation and description, harvesting and yield analysis of test results. Combined with practical work
