摘要: |
根据1992年的试验资料,对半干旱地区马铃薯田水分平衡进行了初步分析。结果表明,全生育期需水量317.3 mm,耗水量250.5 mm,水分亏缺量66.8 mm;水分满足率为78.9%,秋霜冻导致马铃薯减产,使水分生产效率降低。 |

Abstract: |
The water balance in potato field were analysed in Semi-drought region by experimental plot data in 1992.The results showed that the water requirement was 317.3 mm,water consumption 250.5 mm.water diffcient capacity 66.8 mm,and the water satisfaction rate 78.9% in growing period,as well as influence of autumn frost and it brought out the potato reduction in yield and decreased water productive efficiency. |
Key words: potato water requirement water consumption water dificient number water balance |
