chatGPT给出的分析:

错误类型: Saturated water content (SAT) is LESS than drained upper limit. 错误文件: SOIL.SOL 错误行号: 1926 错误代码: IPSOIL

根据错误信息,饱和含水量 (SAT) 小于排水上限 (drained upper limit)。这可能表示在 SOIL.SOL 文件的第 1926 行存在问题。您需要检查该行的输入值,确保饱和含水量不低于排水上限。您可以打开 SOIL.SOL 文件,查找第 1926 行并检查相关的数值。

此外,根据 WARNING.OUT 文件的内容,还有一个警告信息指出光合作用方法 (Photosynthesis method) 已从 "L" 更改为 "C",以与作物模型 MZCER 兼容。

请注意,还提供了 RunList.OUT 文件,其中列出了运行列表中的实验、处理和文件名。这些信息可能对进一步分析有用。

SOIL.SOL文件:

我们发现此处应该为0.349,而不是0.394

再次运行DSSAT模型后发现实验输出文件一致。

接下来分析出错原因:

SDUL和SSAT之间存在密切联系,它们都是描述土壤水分特性的参数,但从不同的角度进行描述。

  1. SDUL(排水上限):它表示土壤在饱和状态下可以排出的剩余水分量。换句话说,当土壤处于饱和状态时,SDUL表示剩余在土壤孔隙中的水分量。SDUL通常比SSAT小,因为它考虑了土壤中存在的排水能力。

  2. SSAT(饱和的上限):它表示土壤的最大容水量,即土壤完全饱和状态下所能容纳的水分量。SSAT通常大于SDUL,因为它考虑了土壤孔隙的总容积。

可以说,SDUL是饱和状态下土壤中的剩余水分量,而SSAT是土壤中总的可容纳水分量。它们一起描述了土壤的水分保持能力和排水能力。

根据错误信息,饱和含水量 (SAT) 小于排水上限 (DUL,drained upper limit),即0.389(SSAT) < 0.394(SDUL)

经过检查发现SDUL应该为0.349 < 0.389(SSAT)

Tips

更改实验数据时,最好不要在shell软件中更改,它可能会导致(不知名原因)创建一个新的实验文件!所以最好直接在底层文件中进行更改。

DSSAT模型如何产出农事处方图

DSSAT模型可以通过以下步骤产出农事处方图:

  1. 数据收集与准备:收集所需的土壤数据、气象数据、作物品种特性和管理实践等相关数据。确保数据准确性和完整性。

  2. 模型设置:使用DSSAT模型的相应软件(如DSSAT-CSM)进行模型设置。输入土壤、气象、作物和管理数据,包括土壤性质、种植日期、施肥计划、灌溉方案等。

  3. 模拟运行:运行DSSAT模型进行模拟。根据设定的参数和管理措施,模型将模拟作物的生长、发育、产量和其他农艺特性。

  4. 结果分析:分析模拟结果,包括作物产量、水分利用效率、养分利用效率等。通过对比不同管理方案的模拟结果,评估其对作物产量和农艺特性的影响。

  5. 农事处方图生成:根据模拟结果,生成农事处方图。农事处方图可以包括作物种植日期、施肥量、灌溉量、病虫害防治策略等农事管理建议。这些建议是根据模拟结果和特定的土地条件、作物品种来推荐的。

  6. 解读与应用:解读农事处方图,并根据实际情况进行调整和应用。根据农田实际的土壤状况、气象变化和管理能力等因素,调整农事处方图中的参数和建议。

需要注意的是,DSSAT模型的准确性和可靠性取决于输入数据的质量和模型参数的准确性。因此,在使用DSSAT模型进行农事处方图生成之前,确保收集准确的数据并进行适当的参数化和校准是非常重要的。

此外,DSSAT模型还提供了丰富的图形和统计功能,可用于进一步分析和展示模拟结果。这些工具可以帮助农户、农业专家和决策者更好地理解模拟结果并做出相应的农事管理决策。

Prefixes

For most model input files and experiment observation files, the prefix is constructed from an institute code (2 characters), a site code (2 characters), the year of the experiment (2 characters) and an experiment number (2 characters). For example, an experiment conducted by the University of Florida (UF) at Gainesville (GA) in 1988 (88) would yield a file prefix of UFGA8801. The file prefix conventions used for output files and genotype coefficient files are shown in Table 1.

实验的管理信息 FileX

记录了要模拟的每个“实验”的模型输入。每个实验可以是真实的实验,有相应的观测到的现场数据,也可以是为模拟定义的假设实验。因此,可以存储许多真实和假设实验的输入以供记录并在不同时间使用。文件标题包含实验代码和名称、处理组合以及实验条件的详细信息(田间特征、土壤分析数据、初始土壤水和无机氮条件、苗床准备和种植几何形状、灌溉和水管理、肥料管理、有机残留物应用、化学品应用、耕作操作、环境改造、收获管理)和模拟控制。实验代码使用与文件命名系统相同的约定来提供有关机构、地点、种植年份、实验编号和作物的信息。例如:UFGA8201MZ,是玉米实验‘01’的代码,由 UF(佛罗里达大学)指定的研究所于 1982 年在 GA 地点(盖恩斯维尔)种植。该文件还可以包含提供实验中使用的数据集的人员的姓名以及有关绘图大小的信息等。

Treatments:

There were six treatments(需要创建6个处理) with varying amounts of N fertilizer or legume green manure applied.

Treatment 1: 0 nitrogen, 0 legume green manure(既不施氮、也不施绿肥)

Treatment 2: l00 kg N/ha applied as ammonium sulfate in two splits: 20 kg applied 21 days after planting and 80 kg applied 44 days after planting, with both banded 10 cm below the surface.(施100公斤/公顷的硫铵分两次:第一次是播后21天。。。)

Treatment 3: 200 kg N/ha applied as ammonium sulfate in two splits: 40 kg applied 21 days after planting and 160 kg applied 44 days after planting, with both banded 10 cm below the surface.

Treatment 4: *Caianus caian* *(木豆)* incorporated to a depth of 20 cm.(混合到地下20cm)

​ Incorporation date = 16 April 1987(模型模拟应该在4月16号以前)

Dry matter = 8733 kg/ha(干重)

N concentration = 2.35 %(氮素含量)

Treatment 5: *Canavalia ensiformis* *(刀豆)*incorporated to 20 cm.

​ Incorporation date = 16 April 1987

Dry matter = 7731 kg/ha

N concentration = 2.68 %

Treatment 6: *Mucuna aterrima* *(油麻藤)* incorporated to 20 cm.

​ Incorporation date = 16 April 1987

Dry matter = 5638 kg/ha

N concentration = 2.37 %

Initial Conditions:

Sampling of the soil for initial conditions was done on 16 April 1987. The amount of root residue for plots with treatments 1, 2 and 3 was 1000 kg/ha, 3150 kg/ha for treatment 4, 3260 kg/ha for treatment 5, and 2700 kg/ha for treatment 6. Soils were sampled for soil water content, ammonium, and nitrate in successive 15 cm increments to a depth of 1.2 m. The results are given below.

Treatments 1, 2, and 3:
