摘要
通过研究同心县主要农作物土壤水分与产量、经济效益的对应关系,为指导旱区农业种植提供理论依据。结果表明:6种农作物水分利用效率排序为西瓜>马铃薯>玉米>谷子>糜子>向日葵,而水分利用效益排序为西瓜>向日葵>马铃薯>谷子>玉米>糜子。
The relationship between the soil moisture and the yield and economic benefit of main crops in Tongxin county were studied to provide theoretic basis for guiding the cropping in dry-land regions. The results showed that： The WUE of 6 main crops could be put in order as： watermelon 〉 potato 〉 maize 〉 millet 〉 proso 〉 sunflower; and the EBWU of 6 main crops could be put in order as： watermelon 〉 sunflower〉 potato 〉 millet 〉 maize 〉 proso.
