Other Abstract

 Based on 30 years long⁃term fertilization experiment on the semiarid Loess Plateau in
China, we studied the effect of different fertilizer treatments on the winter wheat yield, fertilizer
contribution rate (FCR) and precipitation use efficiency (PUE) in different precipitation years
(drought, normal and wet years). The result showed that the wheat yield, FCR and PUE were sig⁃
nificantly higher in nitrogen + phosphorus (NP) and nitrogen + phosphorus +potassium (NPK)
treatments than in control (CK) and phosphorus (P) treatments when winter wheat was planted for
30 consecutive years. The wheat yield, FCR and PUE in NPK treatment were highest, with values
of 3480 kg·hm
, 61.45 kg·kg
and 6.13 kg·mm
, respectively, and those in the wet
years were higher than in drought and normal years. The stepwise regression analysis showed that
wheat yield was mainly influenced by the amount of nitrogen, phosphorus input and precipitation
during fallow period and wintering period. Accordingly, increasing nitrogen and phosphorus input
accompanying with potassium and water conservation practices during the fallow period could im⁃
prove the wheat yield on the semiarid Loess Plateau in China.
