摘要

利用 CROPWAT 8.0 和 CLIMWAT 2.0 模型以及通过 NASA 数据访问浏览器收集的有关气候、土壤、作物和水分供应的数据，估算了印度恰尔肯德邦不同农业气候区水稻的作物需水量。计算了恰尔肯德邦四个区的蒸散量（ETo）、有效降雨量（Peff）和作物需水量（CWR）。结果显示，在不同区域的水稻生长季节，参考蒸散量（ETo）从 420.4 毫米到 516.5 毫米不等。有效降水量从 748.4 毫米到 760.8 毫米不等。水稻作物需水量从 482.5 毫米到 592.4 毫米不等。除冲积区的净灌溉需水量仅为 67.6 毫米外，大部分地区的有效降水量足以满足水稻的需水量。

Crop water requirement of rice in different agroclimatic zones of Jharkhand

The crop water requirement of rice in different agroclimatic zones of Jharkhand, India was estimated using the CROPWAT 8.0 and CLIMWAT 2.0 models with data collected through NASA data-access-viewer on climate, soil, crop, and water availability. The evapotranspiration (ETo), effective rainfall (Peff), and crop water requirement (CWR) for the four zones of the Jharkhand State were calculated. Results revealed that the reference evapotranspiration (ETo) varied from 420.4 mm to 516.5 mm during the crop growing season of rice in different zones. The effective precipitation varied from 748.4 mm to 760.8 mm. The crop water requirement of rice varied from 482.5 mm to 592.4 mm. Effective rainfall was sufficient to meet the water requirement of rice in most of the zones except Alluvial zone wherein the net irrigation water requirement was only 67.6 mm.
