贵州省淡季种植番茄灌溉量时空分布特征
Temporal and Spatial Distribution of the Irrigation Volume of Tomatoes in Guizhou Province
中文摘要：
根据2011—2015年贵州省51个常规地面气象观测站逐日资料及自动土壤水分观测站资料，利用农田土壤水分平衡方程，计算了贵州省淡季番茄生育期灌溉量。简要分析了贵州省淡季番茄灌溉量的空间分布特征，以及不同播种日期番茄灌溉量的时空变化特征；同时利用Python语言对最小灌溉量播种日期进行EOF分析，找到灌溉量最小播种日期及地区，对增加贵州省淡季番茄产量及降低成本有指导性作用。

Abstract：
Based on the data of daily of meteorological stations (2011—2015) in Guizhou Province and automatic soil water observation station data, the irrigation volume of tomato in the off-season in Guizhou Province was calculated by using the farmland soil moisture balance equation. The spatial distribution characteristics of tomato irrigation volume in the off-season in Guizhou Province and the temporal and spatial variation characteristics of tomato irrigation volume in different planting dates were analyzed. Meanwhile, the Python language was used to carry out EOF analysis on the sowing date with minimum irrigation volume, so as to find out the sowing date and region with minimum irrigation volume, which has a guiding effect on increasing the output of tomatoes in the off-season of Guizhou Province and reducing the cost.
