在运用地力差减法进行施肥配方设计时,100kg经济产量吸氮量是确定氮肥用量的重要技术参数之一。我中心通过近几年测土配方施肥项目多点次肥效试验分析,探明了新野县冬小麦100kg经济产量吸氮量,研究结果报告如下。一、研究方法概述该研究引用数据为2007—2011年22点次小麦肥效试验统计结果,统计表中序号1~10为3414试验,序
In the application of fertility reduction formula fertilization formula design, 100kg economic yield nitrogen absorption is one of the important technical parameters to determine the amount of nitrogen fertilizer. My center through the soil testing and fertilizer project in recent years, multi-point fertilizer efficiency test analysis proved the Xinye County winter wheat 100kg economic yield nitrogen uptake, the results are reported as follows. I. Overview of research methods The data of this research are statistical results of wheat fertilization experiment at 22 o’clock in 2007-2011. The numbers 1 to 10 in the statistical table are 3414 tests,
