摘要

分析了作物生产潜力常规研究方法的不足,探讨了作物生长模型模拟方法的优势,在模型验证和气象、土壤和作物数据库组建的基础上,应用DSSAT3中的CERES小麦模型模拟研究了黄土高原地区28个代表点冬小麦和春小麦的光温生产潜力和气候生产潜力,统计计算了各点小麦产量潜力多年平均值、标准差、最高值和最低值,分析了潜力值年际变异与地区分布差异,并计算了小麦的水分满足率。黄土高原冬小麦光温生产潜力、气候生产潜力和水分满足率分别为7970～8647kg/hm2、2219～7545kg/hm2和0.278～0.872,春小麦分别为7436～9127kg/hm2、0～7598kg/hm2和0.192～0.961。

Abstract

The shortcomings of traditional research method on crop productive potential were analyzed,and advantages of crop growth modeling on the field were proposed.Based on model validation and establishment of weather,soil and crop parameter database,the CERES wheat model of DSSAT3 was used to simulate wheat thermal potential productivity (TPP) and climate potential productivity (CPP) of 28 sites on the Loess Plateau region.The mean yield,yield standard deviation,maximum yield and minimum yield of wheat TPP and CPP were calculated for each site.The annual and locational changes of TPP and CPP were analyzed,and water content ratio (WCR,WCR=CPP/TPP) was calculated.The values of TPP,CPP and WCR of winter wheat on Loess Plateau are 7,970～8,647kg/ha,2,219～7,545kg/ha and 0.278～0.872 separately.And values of TPP,CPP and WCR of spring wheat in the region are 7,436～9,127kg/ha,0～7,598kg/ha and 0.192～0.961 respectively.
