Figure 1. Precipitation distribution in the study area from 2009 to 2017, during the growth stage of winter wheat and the fallow season. PF, PS-J, PJ-A, and PA-M denote the precipitation during the fallow, sowing, anthesis, and maturity stages of wheat, respectively (Note: Fallow period: 20 Jun to 30 Sep; SS-WS (sowing stage–wintering stage): 01 Oct to 30 Nov; WS-JS (wintering stage–jointing stage): 1 Dec to 25 Apr; JS-AS (jointing stage–anthesis stage): 26 Apr to 1 May; AS-MS (anthesis stage–maturity stage):2 May to 9 Jun, PGT: total growth period and PT: total precipitation, respectively) : Effects of Nutrient Management Strategies on Yield Formation of Dryland Wheat in the Loess Plateau of China : Science and Education Publishing
