| 为探究麦后复种绿肥对后茬小麦产量、土壤性质及经济效益的影响，为宁夏引黄灌区绿肥还田下小麦增产及土壤肥力提升提供技术支撑，本试验通过随机区组设计，设置T1（小麦-休闲，CK）、T2（小麦-毛叶苕子）、T3（小麦-油菜）和T4（小麦-毛叶苕子、油菜混播）4个处理，分析不同处理对小麦产量、土壤理化性质、活性有机碳库、土壤酶活性及经济效益的影响。结果表明：与对照相比，2022年和2023年麦后复种绿肥处理的后茬小麦产量均能显著提高（P<0.05），增幅分别为8.16%~35.35%和8.72%~41.09%，不同处理对千粒质量和穗长有显著影响，而对小麦产量、穗粒数和穗粒质量有极显著影响（P<0.01），其中，T2产量最高，达到了9 150.87 kg·hm-2和9 523.18 kg·hm-2。复种绿肥显著增加了土壤养分、活性有机碳库及胞外酶活性，降低了土壤pH和全盐含量。主成分分析综合肥力影响为：T2>T3>T4>T1。2022年和2023年T2、T3较T1处理净收益分别增加了37.74%、42.44%和48.31%、54.77%。研究表明，麦后复种绿肥改善了灌区麦田土壤性质，提高了土壤综合肥力，从而增加了后茬小麦产量，其中，复种毛叶苕子是宁夏引黄灌区麦田发展培肥增效的一种有效种植模式。 |

| This study investigated the effects of multiple cropping green manure after wheat on the yield, soil properties, and economic benefits of subsequent wheat, with the goal of providing a scientific basis for increasing wheat yield and enhancing soil fertility in the Ningxia irrigation area. A randomized block design was employed with four treatments：T1（wheat-fallow, control）, T2（wheat-hairy vetch）, T3（wheat- rape）, and T4（wheat-hairy vetch and rape mixture）. Mature wheat plants and soil samples were collected to analyze the effects of different treatments on wheat yield, soil physicochemical properties, active organic carbon pool, soil enzyme activities, and economic benefits. Results showed that, compared with the control, multiple cropping green manure significantly increased subsequent wheat yields in both 2022 and 2023（P<0.05）, with yield increments ranging from 8.16% to 35.35% and 8.72% to 41.09%, respectively. Different treatments significantly affected thousand-kernel mass and spike length, and had highly significant effects（P<0.01）on wheat yield, grains per spike, and grain mass per spike. Among the treatments, T2 achieved the highest yields of 9 150.87 kg·hm-2 in 2022 and 9 523.18 kg·hm-2 in 2023, respectively. Multiple cropping green manure significantly enhanced soil nutrients, active organic carbon pool, and extracellular enzyme activities（EEAs）but reduced soil pH and total salt content. Principal component analysis（PCA）revealed the following order of comprehensive soil fertility：T2 > T3 > T4 > T1. The economic benefits of T2 and T3 increased by 37.74% and 42.44% in 2022 and 48.31% and 54.77% in 2023 compared with T1, respectively. In conclusion, multiple cropping green manure after wheat can improve the soil properties in irrigated wheat fields, enhance overall soil fertility, and increase the yield of subsequent wheat, with multiple cropping hairy vetch being an effective farming system for enhancing soil fertility in the Ningxia Yellow River irrigation area. |
