| 摘要: |
| 【目的】研究种植模式和灌溉方式双因素对冬小麦和夏棉花生长状况、产量品质及综合经济效益的影响，为黄河流域麦棉两熟区种植模式和灌溉方式的科学选择提供理论依据。【方法】采用裂区设计开展大田试验，将麦棉种植模式设定为主区，主区包含麦棉套种和麦后移栽2个水平，副区为灌溉方式，包含畦灌、微喷带灌溉和地表滴灌3个水平，共6个处理。【结果】相比于麦棉套种模式，麦后移栽模式能够提升冬小麦叶面积指数（LAI）和产量，大幅提高冬小麦净收入；虽然麦后移栽模式下棉花籽棉产量降低了5.64%，但麦棉合计净收入比麦棉套种模式下提高8.64%。相比于畦灌和微喷带灌溉，地表滴灌能够显著提高麦棉株高、LAI、产量和经济效益，地表滴灌条件下的麦棉合计净收入比畦灌、微喷带灌溉条件下分别提高36.01%和10.10%。采用麦后移栽和地表滴灌组合下的麦棉合计净收入最高，最高麦棉合计净收入为15924.9元/hm2。【结论】麦后移栽和地表滴灌分别是适宜于黄河流域麦棉两熟区的种植模式和灌溉方式。 |

| Abstract: 【Objective】The effects of planting patterns and irrigation methods on growth, yield, quality and comprehensive economic benefits of winter wheat and summer cotton were studied to provide theoretical basis for scientific selection of planting patterns and irrigation methods in wheat-cotton double cropping areas of the Yellow River Basin. 【Method】The split plot design was used to carry out the field test. The planting pattern was set as the main area. The main area included two levels of the wheat-cotton intercropping and the transplanting cotton after wheat harvest. The secondary area was irrigation method, including border irrigation, micro-sprinkling hose irrigation and surface drip irrigation. A total of 6 treatments were set. 【Result】The pattern of transplanting cotton after wheat harvest improved leaf area index (LAI) and yield of winter wheat, and significantly increased the net income of winter wheat compared with the pattern of wheat-cotton interplanting. Although the cotton seed cotton yield under the pattern of transplanting cotton after wheat harvest decreased by 5.64%, the total net income of winter wheat and summer cotton was 8.64% higher than that under the pattern of wheat-cotton interplanting. Compared with border irrigation and micro-sprinkling hose irrigation, surface drip irrigation significantly improved the plant height, LAI, yield and economic benefits of winter wheat and summer cotton. The total net income under surface drip irrigation was 36.01% and 10.10% higher than that under border irrigation and micro-sprinkling hose irrigation, respectively. The highest total net income of 15924.9 yuan/hm2 was obtained in the pattern of transplanting cotton after wheat harvest under surface drip irrigation. 【Conclusion】Transplanting cotton after wheat harvest and surface drip irrigation are suitable planting pattern and irrigation method for the wheat-cotton double cropping system in the Yellow River Basin, respectively. |
