摘要

时事性。最近,人们越来越关注寻找由可再生能源即植物原料生产的能源。关于栽培技术要素,特别是播种率对用于生物燃料生产的普通双色高粱和高粱生产力形成的影响的相关研究越来越多。关于栽培技术要素,特别是播种率对用于生物燃料生产的普通双色高粱和高粱生产力形成的影响的相关研究越来越多。在乌克兰东部森林草原,这些作物的生产力在很大程度上取决于品种、环境条件和栽培技术要素。优化播种率是提高粮食和生物质产量以及生物燃料和能源产量的方法之一。目的。本研究旨在确定播种率对乌克兰东部森林草原条件下普通双色高粱和高粱能量生产力的影响。方法。2016-2020年,在乌克兰东部森林草原水分不稳定带的国家农业科学院生物能源作物和甜菜研究所伊万诺夫卡研究育种站进行研究,试验设计包括:因子A -品种Dniprovskyi 39(普通双色高粱)和Samaran 6 (soryz);因子B -播种率:1)150倍。个人电脑/公顷;2) 200这个。个人电脑/公顷;250年代。个人电脑/公顷。结果。结果表明,不同播量对高粱和高粱的籽粒产量、生物量产量、籽粒生物乙醇产量、地上质量固体燃料产量和总能量输出均有影响。播量为200株时,籽粒和生物量产量最大。普通双色高粱的产量分别为6.8和39.2 t/ha,普通双色高粱的产量分别为5.9和36.1 t/ha。结论。Dneprovsky 39和Samaran 6的生物乙醇和能量产量分别为2.24 t/ha和56.04 GJ/ha,分别为1.95 t/ha和48.63 GJ/ha。高粱和高粱的固体燃料和能量产量最高,分别为9.06 t/公顷和147.6 GJ/公顷,高粱和高粱分别为8.34 t/公顷和135.93 GJ/公顷。为生产生物燃料和能源资源,栽培普通双色高粱,出苗率可达200‰。pc /ha效率更高。关键词:品种,产量,粮食,生物质,生物乙醇,固体燃料,能源

Energy productivity of common bicolour sorghum (Sorghum bicolor (L.) Moenh) and soryz (Sorghum orysoidum) depending on seeding rates
Topicality. Recently, attention is being increasingly focused on the search for energy resources produced from renewable energy sources, namely from plant raw materials. There are increasingly relevant studies on the influence of elements of cultivation technology, in particular, seeding rates, on the formation of productivity of common bicolour sorghum and soryz used for biofuel production. There are increasingly relevant studies on the influence of elements of cultivation technology, in particular, seeding rates, on the formation of productivity of common bicolour sorghum and soryz used for biofuel production. In the eastern Forest-Steppe of Ukraine, the productivity of these crops largely depends on the variety, environmental conditions and elements of cultivation technology. Optimisation of seeding rates is one of the ways to increase grain and biomass yield and biofuel and energy output. Purpose. Our research aimed to determine the impact of sowing rates on the energy productivity of common bicolour sorghum and soryz in the conditions of the eastern Forest Steppe of Ukraine. Methods. In 2016–2020, the research was carried out at the Ivanivka Research and Breeding Station of the Institute of Bioenergy Crops and Sugar Beet of NAAS in the unstable moisture zone of the eastern Forest-Steppe of Ukraine The experimental design included: factor A – varieties Dniprovskyi 39 (common bicolour sorghum) and Samaran 6 (soryz); factor B - seeding rates: 1) 150 ths. pcs/ha; 2) 200 ths. pcs/ha; 250 ths. pcs/ha. Results. It was found that the different seeding rates have an impact on grain and biomass yield of sorghum and soryz, respectively, and on the estimated yield of bioethanol from grain, solid fuel yield from aboveground mass and total energy output.

For the production of biofuel and energy resources, the cultivation of common bicolour sorghum with a seeding rate of 200 ths. pcs/ha is more efficient.
