Effects of water application uniformity using a center pivot

发布时间：2022-01-26 12:49

　　In recent years, the use of fertigation technology with center pivot irrigation systems has increased rapidly in the North China Plain（NCP）. The combined effects of water and nitrogen application uniformity on the grain yield, water use efficiency（WUE） and nitrogen use efficiency（NUE） have become a research hotspot. In this study, a two-year field experiment was conducted during the winter wheat growing season in 2016–2018 to evaluate the water application uniformity of a center pivot with two l...
