大麦与谷类科学

为种植大户探索一种简便的增产模式，通过比较伟隆169单播、西农865单播、陕道198单播、1/3伟隆169+2/3陕道198混种、1/2伟隆169+1/2陕道198混种、2/3伟隆169+1/3陕道198混种、1/2伟隆169+1/2西农865混种、1/2西农865+1/2陕道198混种8个处理的小麦农艺性状、产量及其构成因素，发现1/3伟隆169+2/3陕道198混种、1/2伟隆169+1/2陕道198混种产量依次居前2位，分别较陕道198单播增产1.43%、1.38%，且分别较伟隆169单播增产9.43%、9.35%。虽然混种产量与单播产量差异无统计学意义，但操作简便，不增加生产成本，对种植大户而言，仍可提高一定的经济效益。建议结合地力、气候选择伟隆169和陕道198混种。

In order to explore a simple method for increasing crop yields for large-scale growers, eight agronomic traits, yields, and their constituent factors were compared including Weilong 169 single planting, Xinong 865 single planting, Shandao 198 single planting,1/3 Weilong 169+2/3 Shandao 198 mixed planting, 1/2 Weilong 169+1/2 Shandao 198 mixed planting, 2/3 Weilong 169+1/3 Shandao198 mixed planting, 1/2 Weilong 169+1/2 Xinong 865 mixed planting, and 1/2 Xinong 865+1/2 Shandao 198 mixed planting. The results showed that the yields of 1/3 Weilong 169+2/3 Shandao 198 mixed planting and 1/2 Weilong 169+1/2 Shandao 198 mixed planting ranked first and second, respectively, which were 1.43% and 1.38% higher than that of Shandao 198 single planting, and9.43% and 9.35% higher than that of Weilong 169 single planting. Although there is no significant difference in yield between mixed planting and single planting, the operation is simple and does not increase production costs. For large-scale growers, it can still improve certain economic benefits. It is suggested that Weilong 169 and Shandao 198 mixed planting should be selected based on soil fertility and climate.
