| 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. |
