Kunz C.、Sturm D.J.、Sökefeld M.、Gerhards R. (2017)：不同覆盖作物覆盖下的杂草抑制和早期甜菜发育。植物保护。科学，53：187-193。 2014-2015年和2015-2016年在两个地点进行了田间试验，研究覆盖作物覆盖物对甜菜的杂草抑制能力。在所有四个实验中测试了三种覆盖作物和两种覆盖作物混合物。藜属 (Chenopodium album L.) 和繁缕 (Stellaria media (L.) Vill) 的杂草密度范围为 2 至 210 株/平方米。作为优势种。白芥子 (Sinapis alba) 的生长速度明显快于野豌豆 (Vicia sativa)、萝卜 (Raphanus sativus var.)。尼日尔，两者都覆盖作物混合物。白芥子 (Sinapis alba)、野豌豆 (Vicia sativa)、萝卜 (Raphanus sativus var.)尼日尔所有地点的杂草密度分别降低了 57%、22% 和 15%。与没有覆盖作物覆盖物的对照地块相比，七种不同覆盖作物的混合物减少了 64% 的杂草出现。 2015 年，所有覆盖处理都促进了早期甜菜生长，但 2016 年则有所放缓。
Kunz C., Sturm D.J., Sökefeld M., Gerhards R. (2017): Weed suppression and early sugar beet development under different cover crop mulches. Plant Protect. Sci., 53: 187–193. Field experiments were conducted at two locations in 2014–2015 and 2015–2016 to investigate the weed suppressive ability of cover crop mulches in sugar beets. Three cover crops and two cover crop mixtures were tested in all four experiments. Weed densities ranged from 2 up to 210 plants/m2 in Chenopodium album L. and Stellaria media (L.) Vill. as predominant species. Sinapis alba grew significantly faster than Vicia sativa, Raphanus sativus var. niger, and both cover crop mixtures. Sinapis alba, Vicia sativa, Raphanus sativus var. niger reduced weed density by 57, 22, and 15% across all locations, respectively. A mixture of seven different cover crops reduced weed emergence by 64% compared to the control plot without cover crop mulch. Early sugar beet growth was enhanced by all mulch treatments in 2015 and decelerated in 2016.
