摘要
本文把土壤——作物——大气视为一个连续体,应用农田水分平衡方程及人工控制下的大田盆栽试验,分别对贵州省玉米和水稻的总耗水量以及耗水量随时间的变化规律进行了研究。指出省内各地应根据当地干旱气候规律,采取作物合理布局,优化灌溉的必要性。
In the premise of soil-crop-atmosphere being treated as a continuum, by means of farmland hydrological balance equations and the experimental results of field crop potted growing under artificial control, this paper studied the total water consumption of rice and corn and how it varies with time respectively in Guizhou, then put forward the necessity of taking crop rational distribution and superior irrigation according to the drought climate regularity of locality in the province.
