| 摘 要： | 通过研究不同灌水定额下欧李抗逆性状及耗水特性，本试验探索了欧李在宁夏中北部半干旱地区栽培的可行性和最优灌水定额。结果表明：成年欧李树在灌水定额为7 mm时仍能完成生育全过程，表明其具有较强的抗旱性；随着灌水定额的增加，丙二醛含量和细胞膜透性均呈先降低后升高的变化趋势，游离脯氨酸和叶绿素a含量均呈先升高后降低的变化趋势。综合分析欧李抗逆性、耗水特性及水分利用效率可知，灌水定额为20 mm处理是兼顾产量和节水效益的最佳处理，与灌水定额为7 mm处理相比，虽然水分利用效率不高，但产量增加84.08%。总体来看，在该地区将欧李作为经济林兼作生态林的栽培树种，具有良好的经济效益和生态效益。

| Abstract: | Through the experimental research on the stress resistance traits and water consumption characteristics of Eurye vulgaris with different irrigation quotas, the reliability and optimal irrigation quota of Eucalyptus in the semi-arid area of central and northern Ningxia were explored.The research results show that there is a one-dimensional quadratic function curve between different irrigation quotas and malondialdehyde and cell membrane permeability, showing a parabolic shape with an opening upward; there is a one-dimensional quadratic function between different irrigation quotas and free proline and chlorophyll a. The function curve is regular and has a parabolic shape with an opening downward.According to the analysis results of stress resistance, water consumption characteristics and WUE, T3 treatment is the best treatment for both yield and water saving benefits. But the output increased significantly, reaching 8809.40kg·hm2.As a whole, planting Cerasus Humilis, which is both a fruit forest and an ecological forest, has good economic and ecological benefits. |
