Currently, in addition to a wide range of lawn fertilizers on the market, there are new biological products available called biostimulants, fostering plant growth and development. They are based on substances of natural origin, containing plant extracts, hormones or humic substances. Biostimulants exert a positive impact on grass metabolism, stimulating life processes and reducing negative effects of pathogen infestation and adverse environmental conditions like drought, salinity or temperature fluctuations. Disparities and the lack of a uniform position to recognize biostimulants as a strictly specified group pose many problems in legislative issues, with erroneous terminology used in relation to different groups of bioactive substances applied to crops. All this creates a situation when products of untested and unstable effects are placed on the market, even if they sometimes do not have any impact on plant growth despite the claims of the producer. Growth‐promoting potential of biostimulants is very significant, and previous research has shown real benefits of their use. Increasing environmental awareness and environmental regulations is an additional factor positively affecting the development of such products. However, there is still a lack of studies that would fully characterize the reaction of plant metabolic processes to biostimulants. The aim of the study was to review current knowledge of plant biostimulant usage in grassland.

生物刺激剂及其在草地中使用的可能性

当前,除了市场上广泛使用的草坪肥料外,还有新的生物产品称为生物刺激剂,可促进植物的生长和发育。它们基于天然来源的物质,包含植物提取物,激素或腐殖质。生物刺激剂对草的新陈代谢产生积极影响,刺激生命过程,并减少病原体侵染和干旱,盐度或温度波动等不利环境条件的负面影响。差异以及缺乏统一的立场来将生物刺激剂识别为严格指定的群体,在立法问题上造成了许多问题,其中使用的术语与应用于作物的不同类别的生物活性物质有关。所有这一切都造成了一种情况,即未经测试且不稳定的产品投放市场,即使尽管生产者声称其有时对植物生长没有任何影响。生物刺激剂具有促进生长的潜力,这一点非常重要,以前的研究已经表明了其使用的真正益处。增强环境意识和环境法规是积极影响此类产品开发的另一个因素。然而,仍然缺乏充分表征植物代谢过程对生物刺激剂反应的研究。这项研究的目的是回顾目前在草原上使用植物生物刺激剂的知识。生物刺激剂具有促进生长的潜力,这一点非常重要,以前的研究已经表明了其使用的真正益处。增强环境意识和环境法规是积极影响此类产品开发的另一个因素。但是,仍然缺乏充分表征植物代谢过程对生物刺激剂反应的研究。这项研究的目的是回顾目前在草原上使用植物生物刺激剂的知识。生物刺激剂具有促进生长的潜力,这一点非常重要,以前的研究已经表明了其使用的真正益处。增强环境意识和环境法规是积极影响此类产品开发的另一个因素。然而,仍然缺乏充分表征植物代谢过程对生物刺激剂反应的研究。这项研究的目的是回顾目前在草原上使用植物生物刺激剂的知识。
