This study aims to improve the quality and quantity of winter wheat by using the potential of combining the use of cold plasma and waste biorefinery products for improving wheat yield. Plasma was applied by a radio frequency (RF) plasma reactor operated with air for 180 s and 50 W. The waste biorefinery products, including pyroligneous acid, biochar, and azolla compost, were used as plant nutrition. The effects of cold plasma treatment and waste biorefinery products were determined by measuring plant photosynthesis, grain yield, and content of chlorophyll, carotenoids, anthocyanin, protein, and starch. The experiment was conducted during the cropping seasons 2016-18 in a randomized complete block design with four replications. The combination of cold plasma and pyroligneous acid increased the grain yield up to 40.0%. The photosynthesis rate was improved up to 39.3%, and total chlorophyll content up to 48.3% in both years. Seed plasma treatment combined with biochar application increased the starch content by 36.8%. Adding azolla compost increased the protein content by 35.4%. Using seed plasma treatment with biochar increased the microbial biomass carbon by 16.0%. The application of plasma and azolla compost increased the microbial biomass nitrogen by 29.0%.
本研究旨在通过利用冷等离子体和废弃生物炼制产品相结合的潜力来提高冬小麦的产量和质量。采用射频（RF）等离子体反应器，以空气为工作气体，处理时间 180 秒，功率 50 瓦。将废弃生物炼制产品（包括木醋液、生物炭和满江红堆肥）用作植物营养。通过测量植物光合作用、籽粒产量以及叶绿素、类胡萝卜素、花青素、蛋白质和淀粉含量来确定冷等离子体处理和废弃生物炼制产品的效果。该实验于 2016-2018 年在随机完全区组设计中进行，重复 4 次。冷等离子体和木醋液的组合使籽粒产量提高了 40.0%。在两年中，光合作用率提高了 39.3%，总叶绿素含量提高了 48.3%。种子等离子体处理与生物炭应用相结合使淀粉含量增加了 36.8%。添加满江红堆肥使蛋白质含量增加了 35.4%。使用种子等离子体处理与生物炭相结合使微生物生物量碳增加了 16.0%。等离子体和满江红堆肥的应用使微生物生物量氮增加了 29.0%。
