谷类-豆类混合种植的好处是一种可持续的农业实践。然而，对半无叶豌豆品种基因型差异的了解不足以帮助它们与谷物竞争。在这项研究中，研究了立陶宛最新的豌豆品种（“Egle DS”和“Lina DS”）的效果，以及作为比较的在混作系统中与燕麦建立的对照品种（“Jūra DS”）的效果。经过三年的田间试验（2018 年、2019 年和 2020 年），共进行了四次实验，涉及每种豌豆品种与燕麦的三种不同混合物。发现混作新豌豆品种的地上生物量明显更高：与对照品种“Jūra DS”相比，品种“Egle DS”的生物量平均增加了 17.0%，“Lina DS”平均增加了 7.2%。对于混合种植系统，与豌豆单一种植相比，50%豌豆+50%燕麦和60%豌豆+40%燕麦的植物比例在统计上观察到更高的地上总生物量。混合种植燕麦是所有测试的混合物成分中的优势物种；然而，与对照品种相比，当将新豌豆“Lina DS”和“Egle DS”品种纳入混合物中时，混合作物的谷物总产量最高。与其他测试的豌豆品种相比，新豌豆品种“Egle DS”对蛋白质含量的影响更大。在豌豆新品种‘Lina DS’和‘Egle DS’中，豌豆与燕麦混作具有较高的光合能力和地上生物量，在混作系统中表现出混合效应，与单作豌豆相比，可以提高总产量。一般来说，新豌豆品种表现出更高的土地当量比（LER）值，导致所有三年和所有四次实验的混合物平均产量最高。未来的研究可以优化豌豆品种与谷物的混合物的效果，以进一步提高有机混合种植系统的产量。
The benefits of cereal-legume mixed cropping is a sustainable agricultural practice. However, knowledge of the genotypic differences of semi-leafless pea varieties is not enough to help them compete with cereals. In this study, the effects of Lithuania’s newest Pisum sativum cultivars (‘Egle DS’ and ‘Lina DS’) and, for comparison, a control cultivar (‘Jūra DS’) established with Avena sativa in mixed cropping system were investigated. Three years of field trials (2018, 2019 and 2020) with four experiments involved three different mixtures of each field pea cultivar with oat. The aboveground biomass of mixed cropped new field pea cultivars was found to be significantly higher: biomass of cultivars ‘Egle DS’ increased by 17.0% and ‘Lina DS’ by 7.2% on average compared with the control cultivar ‘Jūra DS’. For the mixed cropping system, statistically greater total aboveground biomass was observed with plant ratios of 50% pea + 50% oat and 60% pea + 40% oat compared to peas monocultures. Mixed cropped oat was the dominant species in all tested mixture compositions; however, the highest total grain yield of mixed crops was obtained when new pea ‘Lina DS’ and ‘Egle DS’ cultivars were included in the mixtures compared with the control cultivar. The new pea cultivar ‘Egle DS’ had a greater effect on protein content compared to other tested pea cultivars. In the new pea cultivars ‘Lina DS’ and ‘Egle DS’, the higher photosynthetic capacity and aboveground biomass of mixed cropped pea with oat showed mixture effects in the mixed cropped system and could increase total yield compared with pea monoculture. Generally, the new pea cultivars displayed a greater Land Equivalent Ratio (LER) value, resulting in the greatest yield among the mixtures on average for all three years and all four experiments. Future research could optimize the effects of pea cultivar mixtures with cereals to further improve the yield of organic mixed cropping systems.
