汉中丘陵生态区田湿土粘,地力水平低,直接影响小麦产量。为此,笔者根据有关调查资料,应用 Pferffer 等人提出的肥料效应进行回归分析,采用联合国粮农组织(FAO)的方法计算大面积生产中最高产量施肥量和最佳经济产量施肥量。旨在探讨汉中丘陵区小麦对氮肥的效应,以便根据产量结构与施氮水平的关系,确定该区小麦栽培生理指标和施氮指标。
Hanzhong hilly eco-area wet soil sticky, low ground fertility, a direct impact on wheat yield. Therefore, based on the survey data, the author uses the fertilizer effect proposed by Pferffer et al. To conduct regression analysis and calculates the highest yield fertilization and the best economic yield fertilization in the large-scale production by using the method of the United Nations Food and Agriculture Organization (FAO). The aim was to explore the effect of wheat on nitrogen fertilizer in the hilly area of Hanzhong in order to determine the cultivation physiological indexes and nitrogen application indexes of wheat in this area according to the relationship between yield structure and nitrogen application level.
