棉花 气候变化 模型 生产潜力
2020/4/26
【目的】运用农业技术转移决策支持系统(Decision support system for agrotechnology transfer, DSSAT)模型分析石河子地区气候变化对棉花生产潜力的影响,为棉花种植管理的可持续发展提供思路。【方法】本研究以石河子地区田间试验数据为基础,验证DSSAT V4.7模型适用性,模拟棉花光温生产潜力和气候生产潜力,并分析了气候变化对棉花生产潜力的影响。【结...
基于DSSAT模型的吉林省黑土作物-土壤氮循环和土壤有机碳平衡
DSSAT模型 土壤氮循环 敏感性分析 作物氮吸收
2011/10/21
应用DSSAT模型中的CERES-Maize作物模型和Century土壤模型,分析了作物管理参数、施肥量、土壤初始氮含量和作物桔杆还田对吉林省黑土地区玉米生长、氮循环以及有机碳氮生态平衡的影响.结果表明:在玉米目标产量为12000~15000 kg·hm-2条件下,最佳施氮肥量为200~240 kg N·hm-2.在该氮肥用量下,玉米地上氮吸收量为250~290kg N·hm-2,其中,120~1...
