| 摘 要： | 通过设置垄作全膜、垄作半膜、平作全膜以及平作半膜4个覆膜耕作处理,采用加权灰色关联模型评价不同覆膜耕作方式的优劣.结果表明:垄作全膜处理保水保温效果明显;干旱条件下,耕作措施较覆膜方式对地温的影响更为明显;而在水量充沛条件下,覆膜方式则表现出对地温更显著的影响.田间起垄耕作结合全膜覆盖的种植方式,有利于干物质的积累,促进滴灌条件下玉米产量的形成,同时提高水分利用效率,为干旱区农业节水和玉米高产提供了技术依据.

| Abstract: | Four film-mulching farming treatments are set, including ridge tillage whole membrane, ridge tillage half membrane, flat whole membrane and flat half membrane.Weighted grey correlation model is adopted to evaluate the advantages and disadvantages of different film-mulching farming modes.The results show that ridge tillage whole membrane treatment has prominent effect of water conservation and heat insulation.Farming measure has more prominent influence on ground temperature compared with film-mulching mode under dried condition.Film-mulching farming modes show more prominent influence on ground temperature under the condition of sufficient water content.Field ridge farming combined with full-film coverage planting mode is beneficial for accumulating dry materials, promoting formation of corn yield under drip irrigation condition, improving water utilization efficiency at the same time, and providing technical basis for agricultural water-saving and high yield of corn in arid area. |
