Bioassays were conducted to determine the efficacy of barley straw liquor in controlling algal growth of 12 freshwater species of algae representing three divisions. Barley straw liquor inhibited the growth of three nuisance algae common in freshwater: Synura petersenii, Dinobyron sp., and Microcystis aeruginosa. However, Selenastrum capricornutum, Spirogyra sp., Oscillatoria lutea var. contorta, and Navicula sp. had significantly increased growth in the presence of straw liquor. The growth of the remainder, Ulothrix fimbriata, Scenedesmus quadricauda, Chlorella vulgaris, Anabaena flos-aquae, and Synedra sp. showed no significant difference from controls. In a related field study, we treated four of six ponds with barley straw and monitored their chlorophyll a levels for one growing season. While phytoplankton populations in all ponds decreased in midsummer, the phytoplankton biomass in treated ponds did not differ significantly from that of control ponds, suggesting that the application of barley straw had no effect on algal growth in these systems.
进行了生物测定，以确定大麦秸秆浸出液对代表三个门类的12种淡水藻类生长的控制效果。大麦秸秆浸出液抑制了淡水中常见的三种有害藻类的生长：彼得森合尾藻、迪诺比鞭毛虫和铜绿微囊藻。然而，羊角月芽藻、水绵属、扭曲颤藻变种和舟形藻属在有秸秆浸出液存在的情况下生长显著增加。其余的丝状绿藻、四尾栅藻、普通小球藻、水华鱼腥藻和针杆藻属的生长与对照相比没有显著差异。在一项相关的田间研究中，我们用大麦秸秆处理了六个池塘中的四个，并在一个生长季节监测它们的叶绿素a水平。虽然所有池塘中的浮游植物数量在仲夏时都有所下降，但处理过的池塘中浮游植物生物量与对照池塘没有显著差异，这表明大麦秸秆的施用对这些系统中的藻类生长没有影响。
