Abstract

ABSTRACT Field experiments were conducted from April 2015 to September 2016 at the Royal Agricultural University, UK to explore the impact of drilling pattern and species mixtures on weed growth and forage yield. The bi-crops of spring field bean (Vicia faba) cv. Maris Bead and Fuego with spring wheat (Triticum aestivum) cv. Paragon were evaluated at four drilling patterns in a randomized complete block design with four replicates and compared against their respective sole crops. Weed DM was 59% higher in the sole cropping systems than the bi-cropping systems. The sole cropping systems outperformed the bi-cropping systems for wheat (in 2016 only) and for bean forage DM yield. However, the bi-cropping systems produced higher total forage DM yields than sole cropping systems. Weed DM was higher in broadcast than in alternate rows systems. Bean forage DM was 74% higher in treatments with alternate rows than in the broadcast treatment. Wheat forage DM was not affected by the drilling patterns. Maris Bead had higher forage DM than Fuego (in 2016 only). It was concluded that bi-cropping can increase land productivity per unit area over sole cropping, whilst improving forage DM yield and providing low cost integrated weed management. Alternate row drilling can improve bi-cropping productivity over the broadcast practice. Abbreviations: LER - Land Equivalent Ratio

双季制小麦(Triticum aestivum)和豆类(Vicia faba)对牧草产量和杂草竞争的影响
摘要2015年4月至2016年9月,在英国皇家农业大学进行了田间试验,以探索钻探模式和物种混合物对杂草生长和牧草产量的影响。对春田豆(Vicia faba)和Fuego与春小麦(Triticum aestivum)的双季作物Paragon在四种钻孔模式下进行了评估,并与各自的单一作物进行了比较。单季系统的杂草DM比双季系统高59%。在小麦(仅2016年)和豆饲料DM产量方面,单季种植制度优于双季种植制度。然而,两熟制的饲料DM总产量高于单熟制。Weed DM在广播中高于在交替行系统中。交替行处理的豆饲料DM比广播处理高74%。小麦饲料DM不受钻孔方式的影响。Maris Bead的饲料DM高于Fuego(仅2016年)。结果表明,与单作相比,双季种植可以提高单位面积的土地生产力,同时提高饲料DM产量,并提供低成本的综合杂草管理。与广播实践相比,交替行钻孔可以提高双季产量。缩写:LER-土地当量比

期刊介绍: Biological Agriculture & Horticulture aims to act as the central focus for a wide range of studies into alternative systems of husbandry, and particularly the biological or organic approach to food production. The Journal publishes work of a sound scientific or economic nature related to any aspect of biological husbandry in agriculture, horticulture and forestry in both temperate and tropical conditions, including energy and water utilization, and environmental impact.
