| 摘 要： | 分析了德州地区主要作物不同生育期需水量与降雨量的吻合性,提出了适合当地气候条件的主要作物及栽培模式,并根据德州地区目前作物种植结构及水资源现状,提出了作物种植结构调整建议。目前水资源亏缺条件下若将春棉花种植面积提高9.3%,冬小麦和夏玉米种植面积减少9.3%,该地区水资源供需可实现平衡。

| Abstract: | According to the suitability of the water requirement and precipitation in a whole growth period for main crops,the suitable main crops and planting modes are suggested in Dezhou,Shandong province.The water resouces and total crop water requirement are analysed,and the adjustment project of the crop planting structure is suggested.If increasing the cotton planting area in spring by 9.3% and reducing the planting area of the wheat in winter and the maize in summer by 9.3%,the water resouces in this region wi... |
