我国北方冬小麦产区,水资源普遍短缺。随着产量的提高,迫切要求掌握高产冬小麦的需水量。为了准确确定冬小麦需水量,以陕西省宝鸡峡试验站冬小麦田间和蒸渗器试验资料为基础,并收集了大量有关资料,分析研究得出了中壤土等冬小麦的需水量与其产量的关系。其在最高产量15000kg/hm~2以下近似呈直线。
China’s northern winter wheat producing areas, water resources are generally in short supply. With the increase of production, there is an urgent need to master the water demand of high-yield winter wheat. In order to accurately determine the water requirement of winter wheat, based on the experimental data of winter wheat field and steam infilter in Baoji Gorge Experimental Station in Shaanxi Province, a great deal of relevant data were collected. The relationship between the water requirement and the yield of winter wheat in middle loam soil was analyzed. Its highest yield 15000kg / hm ~ 2 the following approximate straight line.
