| 中文摘要: |
| 对华北小麦玉米一年两熟地区,小麦机械收获后残茬覆盖与不覆盖两种处理及其与免耕、翻耕和间隔深松三种土壤耕作方式结合条件下,夏玉米光合产物生产、积累、分配和籽粒产量进行了分析。结果表明,残茬覆盖结合深松耕作具有良好效果,其叶面积系数、叶片光合速率、干物质积累量及向籽粒的分配比例分别比不覆盖免耕高13.37%、45.83%、16.97%和3.09%,最终产量显著高于其它处理,比不覆盖免耕高15.9%。 |
| 英文摘要: |
| Based on the double cropping system of wheat-maize in North China, the effects of the combinations of two stubble mulching methods (mulching and no mulching) and three soil tillage methods (no tillage, moldboard plowing and subsoiling) after the harvest of wheat on the production, accumulation and distribution of photosynthetic matter and the grain yield of summer maize were studied. The results showed that the effects of stubble mulching + subsoiling on maize growth were the best, and that its leaf area index, leaf photosynthetic rate, dry matter accumulation and ratio of photosynthetic matter transported into grains were increased by 13.37%, 45.83%, 16.97% and 3.09% respectively, and its yield was increased by 15.9%, as compared with the treatment of no tillage + no stubble mulching. |
