Background Weeds are plants that, although not specially cultivated, grow and often adapt to growing in arable lands. They form an ecological variant of flora, as a historically-formed set of species growing on cultivated soils. For the rational use of the chemical and biological crop protection products and to produce safe and high-quality food, up-to-date data on the floristic diversity of weeds and the patterns of its geographical change are required. The need for a weeds' database arises that allows many specialists to work together independently. However, the great value of any database lies not in its existence, but in the accumulation of data that can be used to analyse the factors affecting the species diversity of weeds. New information A dataset of weed species diversity and their distribution in the European part of Russia, based on the results of the authors' own research from 1999 to 2019, has been created. The dataset includes 24,284 observations of occurrences of weed plants, which were obtained on the basis of 2,049 relevés of segetal plant communities in seven regions of the European part of Russia. In total, the dataset includes information about 329 species of vascular plants growing in 65 farmlands: cereals, spring and winter crops, industrial crops, row crops and perennial grasses (Tretyakova et al. 2020).

俄罗斯欧洲部分的杂草植物数据库

背景杂草是一种植物，虽然不是特别栽培，但在耕地上生长并经常适应生长。它们形成了植物群的生态变体，作为在耕地土壤上生长的历史上形成的一组物种。为了合理使用化学和生物作物保护产品并生产安全和优质的食品，需要有关杂草区系多样性及其地理变化模式的最新数据。出现了对杂草数据库的需求，该数据库允许许多专家独立合作。然而，任何数据库的巨大价值不在于它的存在，而在于积累的数据可以用来分析影响杂草物种多样性的因素。新信息 俄罗斯欧洲部分杂草物种多样性及其分布的数据集，基于作者自 1999 年至 2019 年的研究结果，已创建。该数据集包括 24,284 次杂草发生的观察，这些观察是基于俄罗斯欧洲部分七个地区的 2,049 个植物群落的相关数据获得的。总体而言，该数据集包含有关 65 个农田中生长的 329 种维管植物的信息：谷物、春季和冬季作物、经济作物、行作物和多年生草类（Tretyakova 等人，2020 年）。
