摘要

在可持续农业的背景下,寻找既能促进作物生长又不损害生物多样性的土壤改良剂正受到越来越多的关注。生物炭是有机物热解产生的固体残留物,近来已成为一种有希望提高作物产量的生物产品,但有关其对耕地生物多样性影响的信息却很缺乏。因此,在本研究中,我们在实验室条件下测试了施用生物炭对矢车菊(Centaurea cyanus L.,菊科)(一种受威胁的耕地杂草)发芽和幼苗生长的影响。我们研究了不同浓度生物炭处理下的各种参数,包括发芽率(GP%)、平均发芽时间(MGT)、发芽率指数(GRI)、发芽能(GE%)、幼苗鲜重和干重(毫克)以及胚根长度(毫米):0%(对照)、0.1%、0.2%、0.5%、1% 和 2%。我们的研究结果表明,生物炭浓度为 0.5%和 1%时,GP、GE 和 GRI 显著增加。生物碳浓度为 0.1%时,MGT 略有增加。施用生物炭对幼苗鲜重没有影响,而幼苗干重在 0.5% 生物炭浓度下有明显增加。第一天,0.1% 的生物碳可显著增加胚根长度,第二天,0.2% 和 1%的生物碳可显著增加胚根长度。然而,到了第三天,经生物炭处理的二孢子与对照组之间的胚根长度在统计学上不再有显著差异(即生物炭仅在第一阶段有积极影响)。这些结果表明,施用中等浓度(0.5% 和 1%)的生物炭总体上对青花菜的发芽和幼苗生长最有利。

Low Concentrations of Biochar Improve Germination and Seedling Development in the Threatened Arable Weed Centaurea cyanus
In the context of sustainable agriculture, the search for soil improvers that boost crop growth without harming biodiversity is gaining much attention. Biochar, the solid residue resulting from the pyrolysis of organic material, has recently emerged as a promising bioproduct in enhancing crop yield, but there is a lack of information regarding its effects on arable biodiversity. Thus, in this study, we tested the effect of biochar application on the germination and seedling growth of cornflower (Centaurea cyanus L., Asteraceae), a threatened arable weed, under laboratory conditions. We investigated various parameters, including germination percentage (GP%), mean germination time (MGT), germination rate index (GRI), germination energy (GE%), fresh and dry weight (mg) of seedlings, and radicle length (mm) under biochar treatments at different concentrations: 0% (control), 0.1%, 0.2%, 0.5%, 1%, and 2%. Our findings revealed a significant increase in GP, GE, and GRI at biochar concentrations of 0.5% and 1%. MGT slightly increased at 0.1% biochar. Seedling fresh weight was unaffected by biochar application, whereas seedling dry weight exhibited a significant increase at 0.5% biochar. Radicle length showed a substantial increase under 0.1% biochar on day one, and was significantly higher at 0.2% and 1% biochar on day two. However, by day three, no more statistically significant differences in radicle length were observed between biochar-treated diaspores and controls (i.e., biochar had positive effects only in the first stages). These results suggest that the application of biochar at intermediate concentrations (0.5% and 1%) overall provides the most benefit to the germination and seedling growth of C. cyanus.
