摘要:

以东北春玉米为研究对象,基于2018—2021年锦州农业生态观测站试验数据,对作物生长模型CERES-Maize进行参数校准和验证,模拟不同降水年(平水年、枯水年和丰水年)各水氮管理措施对春玉米产量、水分利用效率和经济收益的影响,以确定不同降水年不同生产目标东北春玉米最优水氮管理方案。结果表明:CERES-Maize模型模拟春玉米发育期和产量的归一化均方根误差均为10%以内,能满足玉米生长过程及产量的模拟精度要求。不同降水年各水氮管理的春玉米最高产量分别为1.08×104、1.16×104、1.13×104 kg·ha-1,其中枯水年最高,平水年最低。获得最高产量的灌溉量分别为185、205和175 mm,施氮量分别为75、175、125 kg·ha-1;不同降水年各水氮管理的春玉米最高水分利用效率丰水年最高,枯水年最低。获得最高水分利用效率的灌溉量分别为175、195、175 mm,施氮量分别为75、175、125 kg·ha-1;不同降水年各水氮管理的春玉米最大经济收益枯水年最大,平水年最小。获得最大经济收益的灌溉量分别为175、205、175 mm,施氮量分别为75、175、125 kg·ha-1

Abstract:

Taken spring maize in Northeast China as the research object, based on the experimental data of Jinzhou Agroecological Observation Station from 2018 to 2021, parameters of CERES-Maize crop growth model were calibrated and verified.The effects of irrigation and nitrogen management on yield, water use efficiency and economic income of spring maize in different precipitation years (normal, dry and wet years) were simulated to find the optimal water and nitrogen management scheme for spring maize in Northeast China under different precipitation years and production targets.The results show that the normalized root mean square error of CERES-Maize model in simulating the growth period and yield of spring maize is less than 10%, which can meet the requirements of the simulation accuracy of the growth process and yield of maize.The highest yields of spring maize under different irrigation and nitrogen management in different precipitation years are 1.08×104, 1.16×104, 1.13×104 kg·ha-1 respectively, which is highest in dry year and lowest in normal year.The highest yields are obtained by irrigation quantity of 185, 205, 175 mm, and nitrogen application amount of 75, 175, 125 kg·ha-1, respectively.The maximum water use efficiency of spring maize under different water and nitrogen management in different precipitation years is the highest in wet year and the lowest in dry year.The highest water use efficiency is obtained by irrigation quantity of 175, 195, 175 mm, and nitrogen application amount of 75, 175, 125 kg·ha-1, respectively.The maximum economic benefits of spring maize under different water and nitrogen management in different precipitation years are the largest in dry year and the smallest in normal year.The maximum economic benefits are obtained by irrigation quantity of 175, 205, 175 mm, and nitrogen application amount of 75, 175, 125 kg·ha-1, respectively.
